Weed Control Guide for Field Crops

HTHE MAIN REASON for cultivating crops is to A control weeds. Chemicals (herbicides) often con­

trol weeds at a considerable savings over cultivation costs, and in some cases herbicides control weeds that cannot be controlled by normal tillage practices. How­ever, tillage is the only practical control measure in some situations.

Cultural Control

WILLIAM F. MEGGITT AND JIM KELLS

Department of Crop and Soil Sciences

(1) No weed competition to the crop with early control of weeds;

(2) Weeds already controlled in cases where wet weather later delays cultivation or spraying;

(3) Less reliance on rainfall to position some herbi­cides in the soil. Generally more reliable weed control than preemergence sprays;

(4) Much more effective control of some perennial weeds (nutsedge) than with preemergence sprays.

Minimum tillage aids in control of annual weeds. The loose soil surface left by this method makes for a dry topsoil layer which discourages growth of weed seedlings.

The field cultivator equipped with duckfoot or wide shovels is one of the best tools for the control of weeds with deep roots, such as bindweed and thistles. Use the disk or springtooth harrow just before the duck-foot shovel if the soil is firm and needs loosening. Unplowed fields of quackgrass can be effectively con­trolled by a well-constructed field cultivator with nar­row shovels if the operation is repeated often and if the season is dry.

The rotary hoe, spiketooth harrow, and weeder are effective on annual weed seedlings in row crops. Use these tools just after planting, while the crop is com­ing up or just after it is up. For effective weed con­trol, use these tools when the weed seedlings are just coming through the ground; weeds with much top-growth may not be controlled.

Plowing is usually necessary to kill and bury a heavy weed growth. Fall plowing brings roots and root-stocks to the surface where they are injured by winter freezing.

Chemical Weed Control

Many chemical weed-killers are now available. Selective control of weeds in crops may be obtained by either foliage sprays (postemergence) or applica­tion of the chemicals to the soil either as preplanting or preemergence sprays.

Preplanting sprays sometimes are applied to the weed before plowing (quackgrass).

Preplant incorporated sprays are incorporated into the soil prior to planting. This is best done by tilling in two different directions. Incorporation is necessary to prevent losses of volatile herbicides (ex. Treflan, Eptam) and increases or assures the activity of other soil applied herbicides.

Some advantages of preplant soil incorporation of herbicides are:

Some disadvantages of preplant incorporation of herbicides are:

(1) Incorporation operation represents added cost and fuel usage in herbicide application;

(2) Soil compaction is increased by the incorpora­tion operation;

(3) Herbicide may be diluted by improper incor­poration (too deep) resulting in reduced weed control;

(4) "Streaking" pattern of good and poor weed control can result from incomplete incorporation. Cross-wise incorporation helps prevent this problem.

(5) Planting operations may be slowed somewhat due to herbicide application and incorporation opera­tion.

Preemergence sprays are applied after planting but before the crop appears above ground.

Some advantages of preemergence herbicide appli­cations are:

(1) No weed competition to the crop with early control of weeds;

(2) Weeds already controlled in cases where wet weather later delays cultivation or spraying;

(3) Planting and herbicide application may be done in one operation;

(4) In the case of corn, herbicides can be used which will not present a hazard to nearby 2,4-D sensi­tive crops and plants.

Some disadvantages of preemergence herbicide ap­plications are:

(1) Preemergence applications are generally in­effective under dry soil conditions. Some preemer­gence herbicides are ineffective if dry conditions per­sist for only a few days; other herbicides may give weed control after as much as 10 days to 2 weeks of dry weather;

(2) On sandy soils, heavy rains may leach the herbicide down to the germinating crop seed and cause injury;

(3) Perennial weeds usually are not controlled by preemergence herbicide applications.

3

Postemergence sprays have the advantage of use in emergencies since they are not applied until the weeds are up. They can be used on any soil type, and soil moisture conditions are not a problem. However, in some cases there is greater risk of crop injury. Post-emergence sprays should not be applied when the plants are already wet with dew or rain. Postemer­gence sprays are usually more effective (though also more injurious to the crop) at high temperatures.

Temperature greatly influences the effectiveness and volatility of many postemergence herbicides. Ideally, postemergence herbicides should be applied when temperatures range betweeen 65 and 85° F. Low tem­peratures (below 60° F) may result in reduced weed control, while temperatures above 85° F may result in crop injury. Late afternoon herbicide applications are less likely to result in herbicide injury than are early morning applications. Early morning application predisposes the crop plant to danger periods of high temperatures, which increases the potential for herbi­cide injury.

Volatile herbicides such as dicamba (Banvel) or ester formulations of 2,4-D or MCP may vaporize at temperatures as low as 70° F. Once they are vapor­ized, wind may move sufficient vapors to areas with sensitive crops to cause crop injury. Extreme caution is required when applying postemergence herbicides near sensitive crops. Amine formulation eliminates the danger of vapor drift; however, spray drift (droplets) may still occur. Reduce the possibility of spray drift by using a maximum of 35 pounds pressure, maintain­ing proper spray boom height and by using fan type nozzles rather than the hollow cone type.

Herbicide Incorporation

Herbicides are incorporated into the soil for several reasons. Some herbicides must be incorporated to overcome volatility or photodecomposition losses which would occur if the materials were left on the soil surface. Other herbicides are incorporated to insure good activity in the absence of the rainfall otherwise required to move the herbicide into the weed seed germination zone. This is often referred to as herbicide "activation." Incorporation is also often required to obtain perennial weed control from soil applications of herbicides.

The most consistent incorporation (no streaking), especially when using a disk or field cultivator alone, is achieved with two passes at an angle to each other. However, new tillage implements have made one-pass incorporation of herbicides a possibility. Many growers are asking what is the best way to achieve one-pass incorporation.

Soil Conditions Although a majority of the questions concerning

incorporation concern the best implement to use for

one-way incorporation* soil condition influences the success of incorporation more than the tool used. The reliability of one-pass incorporation will also be in­fluenced by the tillage system used.

In clean tillage (low crop residue) situations, pre-emergence applications made on wet soil will likely perform as well or better than two-pass incorporated treatments. One-pass incorporation is not a good ap­proach with less than optimum soil tilth.

High crop residue levels (corn stalks disked or chisel plowed with one or two secondary tillage operations) make one-pass incorporation difficult. If the residue level is great enough to clog the incorporation tool, two-pass incorporation is advisable. The soil should also have good tilth, as outlined above.

Where ridges are left from fall plowing or use of a chisel plow in the spring, it is advisable to level the ground before herbicide application. Streaking is fa­vored by application of the herbicide to rough ground.

Incorporation Implements

Disks, especially large tandem disks, are poor tools for incorporation. Depth and ridging are difficult to control. Non-uniform distribution of the herbicide in the soil is a distinct possibility with a disk.

A disk does have a place for special applications, particularly the use of Eradicane to control quackgrass. The disk does a,good job of chopping the quackgrass rhizomes required for good Eradicane activity. The disk should be operated at a depth of 4 to 5 inches and a speed of 4 to 6 mph. Incorporation must be done in two directions.

A field cultivator can give acceptable one-pass incor­poration of herbicides if special care is taken to set-up and operation. Wide sweeps, set-up so they meet, give better incorporation than points. Shanks should be close enough to give this, and three sets of sweeps are also required. It is important to follow with a leveling tool, such as a flex tine drag or spring tooth harrow, to smooth out ridges behind the cultivator.

The speed of the cultivator should be at least 6 mph, depth 3 to 4 inches. Actual incorporation will occur at one-half the tool depth. Caution must be taken not to run the rear portion of the cultivator lower than the front. If the back of the tool is lower, untreated soil can be brought to the surface burying the herbi­cide.

Danish type harrows equipped with "S" tines and rolling baskets can do a good job of one-pass incor­poration. Rolling baskets outperform other trailing operations.

Operation considerations are similar to those with the field cultivator. Again, good soil tilth is a pre­requisite for one-pass incorporation.

PTO driven tools do a good job of one-pass incor­poration. However, their application in Michigan may

be limited. These tools are operated at lower speeds and do not have the tool width the other implements can have.

Principles of Chemical Control of Weeds

1. Weeds are easiest to kill when they are small seedlings and when conditions favor rapid growth. Crop plants also are most easily injured under these conditions. Selective sprays (see Table 1) will control the weeds with little or no injury to the crop,

2. Time of spraying and rate of applications are very important. Spraying at the wrong time often re­sults in poor weed control and greater crop injury. No crop plant is completely resistant to injury from herbicides. Too much chemical will cause damage.

3. With most preemergence herbicides, do not cultivate for at least 3 weeks after preemergence spraying unless weeds appear that are resistant to the chemical. If weeds appear and dry weather persists for 2 weeks after herbicide application, rotary hoe or cultivate shallow. Delay cultivation after post-emergence herbicide applications for at least 2 or 3 days (7 to 10 days following 2,4-D application in com) to allow the chemical to move into stems and roots of the weed plants,

4. No one chemical used as a selective spray will kill all species of weeds. Therefore, select the right chemical for the job. The first step for successful weed control is to identify the weed species present. Some weeds are resistant to all of the present selective sprays.

5. Read current labels carefully and never apply a chemical at rates higher than recommended on the label. Use chemicals only on crops for which they are recommended on the label. Store chemicals in a room not subject to freezing temperatures and away from seed, fertilizer and other pesticides.

Herbicide Combinations

Two or more herbicides are often applied as a tank mix or in separate applications to give more consistent or broader spectrum weed control. Combinations are also used to decrease herbicide residue (for example, atrazine carryover) or to obtain adequate season-long control.

Only recommended or labeled herbicide combina­tions should be used. Growers and applicators are responsible for poor weed control, crop injury or herbicide residue from herbicides labeled for single application but used in combinations.

Pesticide — Fertilizer Compatibility

Combinations of herbicides, insecticides and/or fun­gicides applied in either water or liquid fertilizer car­riers decrease trips over the field and application costs;

however, compatibility is critical. Always test the compatibility of each mixture to be applied and follow label instructions.

A simple compatibility test requires only a glass quart jar and the pesticides and liquid fertilizer to be mixed. Place one pint of liquid fertilizer in the quart jar and add two teaspoons of the liquid pesticide. If the pesticide is a wettable powder, add two teaspoons of powder to sufficient water to form a slurry and add the slurry to the fertilizer. Cover the jar, shake well, and observe the mixture for 30 seconds. Check the mixture again after 30 minutes. If the mixture does not separate, it is compatible; however, check each batch of liquid fertilizer, as they may vary in mixing properties, Also, check compatibility if water source changes, as water pH and mineral content influence compatibility.

If more than one pesticide is to be mixed with liquid fertilizer or water, the pesticides should be premixed in liquid fertilizer or water and tested for compati­bility by mixing appropriate proportions of all com­ponents. The combination should be thoroughly agi­tated before each additional pesticide is added, and a specific mixing order should be followed. Generally, unless label directions state otherwise, add the pesti­cides being tested in the following order: first—wet-table powders, second—flowables, third—water solu­bles, fourth—surfactants and emulsifiable concentrates. Spray tanks should be at least half filled with carrier before the pesticide premixes are added. If the mixture foams excessively, separates or becomes syrupy, do not apply the mixture. Compatibility agents are avail­able which may be added to improve mixing ability.

Even if all components appear compatible, the field tank mixture will require constant, vigorous agitation to prevent separation or improper pesticide distribu­tion in the tank. Be sure the entire tank is agitated and mixed before spraying. Do not store pesticide mixtures overnight unless they are constantly agitated. Best results are obtained by applying the entire mixture in one day, (See Extension Bulletin E-1268)

Additives for Herbicide Use During the development of an herbicide, a major

effort of the chemical company is expended on the formulation of the active ingredient to optimize per­formance, mixing, and handling under diverse condi­tions. Every commercially available herbicide formu­lation contains its own particular set of additives to accomplish this purpose. However, sometimes addi­tional additives are required for specific applications or when compatibility or mixing problems occur. The herbicide label will describe the need and use of these additives. The indiscriminate use of additives should be avoided since they may not improve herbicide per­formance and may actually reduce weed control or cause crop injury.

5

Additives can be referred to as "adjuvants." This merely denotes an added ingredient. Surface active additives are called surfactants. Therefore, all sur­factants are also additives or adjuvants. All herbicide formulations contain surfactants. Emulsifiable concen­trates contain emulsifiers which aid in the dispersion of the formulation into the water phase. Wettable powders contain wetting agents and dispersants which facilitate moistening the tiny particles and prevent clumping. Postemergent herbicides, such as 2,4-D and Roundup, contain wetting agents which help spread the spray over the leaf surface.

When to Use Additives

Some herbicides may be applied either to the soil or postemergence so the addition of a surfactant is left to the user. Sometimes additives are only required for postemergence treatments made during adverse cli­matic conditions. In other cases, the nature of the herbicide may necessitate addition of the surfactant to the spray mix rather than the formulation. The herbicide label always gives directions for such addi­tive requirements.

Although claims have been made for additives in­creasing the effectiveness of soil-applied herbicides, there is no independent data to support these claims. Research in this area was conducted at several univer­sities across the country. These experiments failed to show any benefit from the inclusion of spray additives with soil applied herbicides. Additives are used with postemergence applications to aid coverage of leaf sur­faces and increase penetration into the leaf. Use of additives for soil applications of herbicides can help prevent clogging of lines and nozzles.

Concentrated Crop Oils

"Concentrated" oil additives contain higher percent­ages of emulsifier, combinations of oil, or differing emulsifiers and surfactants than the crop oils or vege­table oils previously used. Concentrated crop oils are generally recommended at a rate of 1 quart per acre.

These additives are recommended for use with post-emergence applications of atrazine and Basagran. They should also be used in postemergence applications on sugarbeets when large weeds are present or the weeds are not vigorously growing. Aatrex and Basagran labels contain directions on the use of additives.

There is a greater risk for crop injury when using additives with postemergence atrazine applications. Injury is frequently associated with cold, wet or cloudy conditions. The injury appears as a temporary stunt­ing plus necrosis of the leaf margins. Banvel, 2,4-D, or Bladex should not be included in a spray mix of atrazine plus crop oil concentrate or severe injury to the corn may occur.

The use of crop oil concentrate is recommended with Basagran to insure good coverage of the weed foliage.

Basagran requires good coverage for optimum weed control. Soybean injury can be increased with the addition of crop oil concentrate to Basagran sprays. When soybeans are growing poorly or were injured from soil applied herbicides, care must be exercised in the use of Basagran plus crop oil concentrate.

Adjuvants, Surfactants, Wetting Agents, Soaps

Many spray additives are currently available and many exaggerated claims have been made for them. In most cases, these materials are no better than crop oil concentrates. In fact, under poor environmental conditions for postemergence weed control, the crop oil concentrates can be slightly superior. Remember that any benefit comes only in postemergence applica­tions, not soil applied herbicides. Also, they aid per­formance of the herbicide in adverse conditions but are not a way to use less herbicide.

The Bladex 80W label calls for the addition of a surfactant or vegetable oil for postemergence applica­tions under droughty conditions. Weeds can harden off in this type of environment and become more diffi­cult to kill. However, because of the increased chance of crop injury and the infrequency of these conditions in the spring, additions of surfactants or oils are not recommended for postemergence Bladex 80W use in Michigan.

The Paraquat CL label calls for the addition of a nonionic surfactant (Ortho X-77). Good coverage is required for this contact herbicide. When paraquat is sprayed with fertilizer solution, be sure the rate of surfactant is increased as outlined on the label.

Roundup is formulated with a surfactant and further additives should not be made to avoid excessive leaf run-off. The addition of a defoaming agent can be a help if excessive foaming is a problem. This is ex­plained in the "Mixing" portion of the Roundup label.

Compatibility Problems

Compatibility problems in tank mixing herbicides usually occur when mixing directions are not followed. Mixing two herbicides in concentrated form, adding an EC to the spray tank first rather than first suspend­ing the wettable powder, insufficient agitation, exces­sive agitation, and air leaks are some of the causes of compatibility problems. Problems are much more likely when mixing herbicides with fluid fertilizer. The fertilizer solution is already loaded to near capacity with nutrients. Adding a herbicide to the already loaded solution may cause problems. Also, the fer­tilizer may interfere with the herbicide formulation additives. Since fertilizer may vary greatly from batch to batch, the only safe procedure is to test for com­patibility in a small container before mixing a large quantity. If compatibility problems are encountered, the addition of compatibility agents may help.

Foaming is usually due to excessive agitation or a bypass line that empties above the spray solution level in the spray tank. When foaming is a problem, addi­tion of a defoamer can help.

Preslurry the powder if you have problems in get­ting a wettable powder to wet and become suspended. Adding a wetting agent to the spray tank will some­times correct a floating powder problem.

Soil Type and Organic Matter

Soil texture (sand, silt, clay) and organic matter influence the effectiveness of soil-applied herbicides. Herbicide rate recommendations in this bulletin are given for medium-textured soils with greater than 3 % organic matter. Clay and organic matter adsorb herbi­cides, making them less available to germinating weeds and crop plants. Soils with high clay and organic matter content require greater herbicide rates for adequate weed control. Sandy soils with low or­ganic matter content require careful herbicide rate selection to avoid crop injury.

Soil pH can influence the activity of soil applied herbicides. Some herbicides (metribuzin) are more available at higher soil pH. Rates must be reduced to avoid crop injury. Knowledge of the soil pH is needed for proper rate determination.

Organic matter analysis is available through county offices of the Cooperative Extension Service or directly through the MSU Soil Testing Laboratory. Organic matter analysis may be determined on soil samples submitted for N-P-K analysis for an additional charge. Organic matter levels change slowly and may need to be checked every four years.

Organic matter analyses are only as accurate or representative as the soil sample, so each field should be checked individually. See Extension Bulletin E-498, Sampling Soils, for proper soil sampling procedure.

Follow herbicide label recommendations and ad­just herbicide rate for soil texture and organic matter as specified on the label.

Herbicide Residues and Bioassay

With the advent of preplant and preemergence herbicides which give season-long weed control, the accumulation of herbicides in the soil and their influ­ence on subsequent crops in the rotation have become important in crop management. This is particularly true since atrazine has come into common use on corn. However, when used at recommended rates in seasons of normal rainfall and temperature, most recom­mended herbicides for field crops do not present a problem on crops planted the following season. Ex­ceptions are listed in "Remarks" column of Table 1.

There have been reports of injury to crops following atrazine applications on corn. There is more likely to be a problem with herbicide residues in a season of limited rainfall and cool temperatures, due to the slow dissipation of the herbicide. (See Extension Bulletin E-1213)

Carry-over problems have been most commonly reported for two groups of herbicides, the triazines (ex. atrazine) and the dinitroanilines. If soybeans follow corn, or sugar beets follow a crop treated with dinitroaniline and if herbicide carry-over is a possibility, a bioassay late in the fall prior to freeze-up or early in the spring may indicate whether enough herbicide is present to harm the crop. A herbicide bioassay is a means of biologically measuring the level of herbicide in the soil. The bioassay procedure is a relatively simple test but a few basic steps should be followed.

1. Collect soil from several locations in the field as when taking soil samples. Reliability of the assay depends on accurate sampling. Sample soil to the depth the field has been tilled. Approxi­mately 5 lb. of soil are needed for each sample. Collect an equal amount of soil from an adjacent field where it is known no herbicide has been applied. This second sample is used as a "check."

2. Start bioassay within one or two weeks after soil is collected to prevent the loss of herbicide under warm conditions. If the assay cannot be run im­mediately, store the soil in a cool place, or even allow it to freeze.

3. If soil is wet, allow it to dry so that it may be worked easily. If the soil is cloddy, crush the clods but do not pulverize.

7

4. Partially fill two 1-qt. containers with soil, one with the soil being tested and the other with soil from the "check" field. Punch holes in the bottom of the containers to allow drainage. Tin cans or milk cartons make satisfactory containers.

5. Plant 15 seeds of a sensitive crop in each container and cover with Vz inch of soil. Wet the soil but do not saturate. Oats are very sensitive to both triazines and dinitroanilines, and sugar beets and sorghum are extremely sensitive to dinitroanilines. Place exactly the same number of seeds in each container. By knowing the exact number of seeds planted, seedling emergence can be measured. Do not plant too many seeds or the seedlings may compete for the herbicide and decrease the injuri­ous effects.

6. Place containers in a warm place (70 to 75° F ) , preferably in a window to receive as much sun­light as possible. Additional artificial light should also be supplied to obtain approximately a 15-hour day length. Water plants sparingly, but do not let soil dry out.

7. Determine plant emergence, and monitor plant growth for at least three weeks after planting. Compare "check" plants with those in the soil being tested.

8. Atrazine injury may cause yellowing of the oat leaves, with the plant becoming droopy and finally dying, or if carry-over is marginal, stunting may occur. Stunting can be determined by a compari­son with "check" plants. Dinitroaniline injury may result in a decrease in seedling emergence and/or stunting of the sugar beet or sorghum.

9. If any evidence of herbicide carry-over is observed, it is advisable to plant a resistant crop.

Weed Sprayers Crop injuries often result when sprayers used for

weed control are also used for disease and insect con­trol. Some chemicals are more difficult to wash from a sprayer than others, and wooden tanks are more difficult to clean than steel tanks. Hand sprayers of 3- or 4-gal. capacity are suitable for small areas of 1 acre or less and for patch spraying. Tractor-mounted sprayers driven from the power takeoff are very satis­factory for larger areas.

A good weed sprayer should: 1. Have a pump which is inexpensive, easily replaced,

resistant to wear and chemicals and has a mini­mum capacity of 4 gal. per minute.

2. Provide some means of keeping the solution well mixed. This can be by mechanical or jet agitation, using a bypass from the pump. Be sure the agita­tion mixes the entire tank. An agitator mounted too far from the tank bottom can leave an unmixed layer on the bottom.

3. Have 50-mesh screens for suction line and nozzles.

4. Have a gauge which measures pressure accurately in the range of 20 to 100 lb. per square inch.

5. Have flat fan nozzles with replaceable tips. Wide angle nozzles (73 to 80 degrees) will permit the boom to be carried closer to the ground and thus reduce spray drift.

Cleaning and Storage Keep weed sprayers clean. Where soil applications

only are practiced, thorough rinsing with water is sufficient. For other spraying purposes, wash out the sprayer (tank, hose, boom, nozzles) with one of the following in 100 gal. water:

1. 1 gal. household ammonia (allowed to stand in sprayer overnight).

2. 5 lb. of sal soda. 3. 8 lb. trisodium phosphate.

Corrosion and mechanical damage to pumps, tanks, nozzles, etc. may result from leaving water in spray equipment over winter. Thoroughly clean spray equip­ment after each spraying operation; however, even when properly cleaned, some water may remain in the sprayer. To prepare the spray equipment for storage, disconnect all hoses, and allow all water to drain. Coat all bare metal parts with oil or a rust inhibitor. Disassemble metal nozzles, and store them in oil. Pre­pare the sprayer pump for storage based on the manu­facturer's recommendations.

Band Application In cultivated crops, spraying narrow bands of herbi­

cide over the rows will take less material per acre, cutting the cost per acre for the chemical. Where chemical costs are high, band spraying may be justi­fied. However, with band spraying, timely cultivation of weeds in the unsprayed area between rows is neces­sary. In seasons when the soil is too wet to cultivate, overall spraying has the advantage of controlling weeds between the rows.

When band spraying, be very careful to maintain the proper rate of application on the area sprayed. (If you lower the spray boom to narrow the area covered by a given nozzle, remember that each nozzle is still delivering the same amount of spray mixture as it did on the wider area.)

Accurate Calibration Accurate sprayer calibration is essential for effective

chemical weed control without crop injury. Calibrate a new sprayer before use and recalibrate a sprayer each year before using. MATERIALS REQUIRED

A quart container graduated in ounces. Sufficient string to tie container to nozzle tip.

PRELIMINARY STEPS

1. Make certain that nozzle tips are of proper type for the spray job and of proper size for gal./acre.

8

2. Be sure all nozzle tips are of the same size and type and that screens are of proper mesh. (For most wettable powders, 50-mesh or coarser screens are recommended.) Check nozzle delivery. All nozzles should deliver within 10% of each other.

3. For spraying wettable powders, be sure the sprayer is equipped with some type of jet or mechani­cal agitation.

PROCEDURE

1. In a band application, accurately determine the width, in inches, of the band sprayed. In a broad­cast application, measure the distance, in inches, between two adjacent nozzles.

2. Locate this width in the table below and read off the corresponding course distance.

WIDTH COURSE DISTANCE (inches) (feet)

8 510 10 408 12 340 14 291 16 255 18 227 20 204 22 185 24 170 26 157

3. In the field to be sprayed, mark off course of the proper distance.

4. Tie quart container to one nozzle on the sprayer so as to catch all of that nozzle's spray when sprayer is turned on.

5. Start a distance back from the beginning of the course to get up to operating speed, and turn sprayer ON at beginning of course and OFF at end of course.

6. Remove quart container, and read volume col­lected IN OUNCES.

7. Ounces collected = gal./acre. This procedure can be used to calibrate sprayers

for both banded and broadcast type applications. For a given recommendation, the actual amount of mate­rial to be applied per square foot of soil treated should be the same for both types of application. Banding reduces the amount of chemical used by reducing the number of square feet treated per acre.

After using the above procedure for calibration of sprayer, remember that the gal./acre figure deter­mined is for each acre (43,560 sq. ft.) treated, NOT necessarily each acre driven over. In a broadcast ap­plication, the acres treated will be equal to the acres driven over.

Granular Formulations Herbicides are available in granular form for dry

application. Granules are usually applied in a band over the row at planting time, but they may also be

broadcast. Usually, equal weed control can be ex­pected from granular and spray formulations, but in some cases granules have not given as good weed con­trol as the sprays. This generally has been due to either the use of equipment giving nonuniform dis­tribution of the granules or to formulations with too high a concentration, resulting in inadequate volume for uniform distribution.

Granular herbicides eliminate the need for a water supply and they reduce the drift hazard. But there still is a volatility hazard from granular formulations of 2,4-D ester or dicamba applied near sensitive crops— especially grapes and tomatoes. Granules give best results on fine, firm seedbeds. A wide, flat press wheel on the planter is desirable for band application at planting. Weed control may be hampered when granules are applied on a rough seedbed, because of uneven application, such as that often obtained with minimum tillage.

The use of granular formulations does not eliminate the need for calibration. Various materials will "feed" differently because of variations in carrier and in particle size. Therefore, granular applicators, like sprayers, should be accurately calibrated.

Herbicide Rates and Spray Volume Table 1 lists chemicals which will give satisfactory

weed control without injury to crops, except as noted under "Remarks." The volume of water to use will vary with the herbicide, although generally 10 to 40 gal. per acre and a spraying pressure of 30 to 40 lb. is recommended for ground equipment. A minimum of 10 gal. of water per acre is recommended for the phenoxy herbicides [2,4-D, MCPA, 4-(2,4-DB)]. With wettable powders such as atrazine and linuron, use nozzles that deliver at least 15 gal. per acre. Use 30 to 40 gal. of spray per acre when spraying quack-grass with atrazine or dalapon. Some contact type postemergence herbicides (Basagran, Blazer) require a minimum of 20 gallons per acre spray volume and 40 psi spray pressure to insure adequate coverage. Flat fan nozzles are effective for herbicide applications. Hollow cone nozzles can also give good results, espe­cially for postemergence applications made at higher pressures. If higher pressures are used, be sure the nozzles are designed to be operated at the increased pressure. Operating nozzles beyond the specified pres­sure range will result in a poor spray pattern, insuffi­cient coverage, and a lack of weed control.

Some herbicides are available in a number of dif­ferent formulations and concentrations. For this reason the recommended rates in Table 1 (col. 3) are given as pounds of active ingredients per acre. Thus when a liquid formulation contains 4 lb. of active ingredient (or acid equivalent) per gallon, 1 pt. will provide Vz lb. of active ingredient, or 1 qt. will provide 1 lb. of active ingredient.
