Trial Comments

Tansy mustard and marestail were present at the early preplant burndown applications; all treatments controlled the winter annual weeds.

Injury to corn appeared as a reduction of plant height.Efficacy ratings included residual control of weed emergence on July 9 and 18.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Could not calculate LSD (% mean diff) for columns 1,2,4,5,6,14,16,21,24 because error mean square = 0.

Trial Comments

Treatment 13 originally contained a sequential postemergence timing that was not applied because excellent weed control was sustained following the POST application.

Plots 102, 103 and 106 contained some yellow nutsedge that was not completely controlled. However giant foxtail control in these plots was 99%.

Common cocklebur pressure was heavier on the side of the experiment with lower plot numbers (e.g. 101, 201, 301).

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Missing data estimates are included in columns:Average=7Could not calculate LSD (% mean diff) for columns 1,2,12,13,14,15,19,24 because error mean square = 0.

SETFA contains a changing mixture of giant foxtail and woolly cupgrass. As plot numbers increase (i.e. 101 to 111) the percentage of woolly cupgrass in the mixture increases.

Ivyleaf morningglory pressure was variable.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Could not calculate LSD (% mean diff) for columns 8,9,10,11,12,15,16,17 because error mean square = 0.

Trial Comments

Grass pressure was heavy in the trial area and covered 100 percent of the soil surface in all three reps on June 12. Velvetleaf covered 10, 50 and 50 percent of the soil in the first, second and third reps, respectively. Common waterhemp andcommon lambsquarters covered only about 5 percent and common cocklebur 10-20 percent ground cover across all 3 reps.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Missing data estimates are included in columns:Average=11,17,22Could not calculate LSD (% mean diff) for columns 1,4,5,6,10,12,16 because error mean square = 0.

Adequate rainfall for herbicide activation did not occur for at least 15 days after the preemergence applications. Treatments 1 through 7 had stunted corn because of weed competition prior to the POST applications.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Could not calculate LSD (% mean diff) for columns 6,14 because error mean square = 0.

Date By Notes5/26/2018 Treatments 2 through 7 were applied on May 25 and rain occurred one hour after application. Treatments 8through13 were applied on May 26 under similar weather conditions with warm temperatures, medium humidity and nearly fullsunlight.

Trial Comments

Common cocklebur pressure was variable in the study area.

Rainfall that occurred shortly after the EPOST application of treatments 2 through 7 may have impacted weed control for some of those treatments more than others.

Weed control ratings for June 27 and July 10 include residual weed control.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Missing data estimates are included in columns:Average=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23Could not calculate LSD (% mean diff) for columns 13 because error mean square = 0.

Trial Comments

Common waterhemp and common cocklebur pressure was greater on the right side of the trial area (plots with larger numbers).

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Missing data estimates are included in columns:Average=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24Could not calculate LSD (% mean diff) for columns 13,18,23 because error mean square = 0.

Trial Comments

Giant foxtail was present in the trial area at much lower densities than woolly cupgrass.

June 6 ratings evaluated residual control by PRE treatments. Ratings from June 14 through June 29 evaluated burndown control from the POST applications, and August 2 ratings evaluated residual control of new weed emergence together with burndown from POST applications.

The PRE application for Trt. 7 was not applied.

Trial Comments

Very small common waterhemp and common lambsquarters plants were present in the control plots on June 13. All treatments with preemergence herbicides achieved 99% control of these two weeds.

Weed control observed on July 5 was only residual control; burndown from postemergence applications was ignored.

Weed control on July 20 was observed as postemergence herbicide activity. Weed control less than 99% was observed as regrowth; weeds had been sprayed but recovered & started to regrow. Excellent residual control was observed for the most part with occasional new germinating velvetleaf and ivyleaf morningglory; Trt. 2 had the most emergence where no residual treatment wasapplied.

Trial Comments

Injury to soybean appeared as leaf crinkling and shortening of leaf mid-veins causing a "drawstring" effect.

Ivyleaf morningglory pressure was variable. Pressure was heavier to the side of the study with smaller plot numbers (i.e. 101, 201 & 301).

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Missing data estimates are included in columns:Average=5,10,15,20

Trial Comments

Alite27 is not registered for use in soybean at this time.

Herbicide injury to soybean appeared as leaf puckering and sometimes as a "drawstring" effect caused by a shortened middle vein.

Percent ground cover for giant foxtail, velvetleaf, common waterhemp and ivyleaf morningglory averaged over July 10 and July 23 for the three reps are listed as follows, respectively:

Plot 101; 97, 20, 20 & 2;Plot 206; 100, 40, 4 & 2%;Plot 311; 100, 20, 3 & 1%

(ASE4) ARM 2018.2 Trial Comments Page 5 of 10




Common waterhemp pressure was lighter on the right side of the experiment (higher plot numbers). Ivyleaf morningglory pressure was uneven.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Could not calculate LSD (% mean diff) for columns 11,12,13,14,15,16 because error mean square = 0.

Trial Comments

Neither Alite27 nor Callisto are registered for use in soybean at this time.Weed pressure was inconsistent in the trial area and made herbicide efficacy evaluation difficult. Initial weed emergence

was just occurring at the May 31 evaluation, and significant rainfall did not occur until June 2.Percent ground cover for giant foxtail, velvetleaf and common waterhemp for the three reps are listed as follows,

Date By Notes5/21/2018 We were not able to apply the Xtendimax treatments (May 21) the same day as the Liberty treatments (May 18).Consequently, there are two application codes for PRE applications.

Trial Comments

Preemergence applications were applied on two dates as depicted by the application codes.

Soybean injury on July 9 appeared as chlorosis and light necrosis.

Treatment 1 soybean showed plant lodging at a 30% angle at harvest.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Could not calculate LSD (% mean diff) for columns 1,2,3,4,5,6,7,8,9,10,11,12 because error mean square = 0.

Trial Comments

Corn injury for Treatment 5 appeared as necrosis on June 15 and 20. Velvetleaf pressure was variable in the experiment.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Missing data estimates are included in columns:Average=3,6,7,8,9Could not calculate LSD (% mean diff) for columns 1,7 because error mean square = 0.

Trial Comments

Weed pressure in the experiment was light.

For demonstration purposes, corn was not planted in the first rep, and the first two reps were not randomized.

Herbicide injury to corn appeared as chlorosis and stunting.

Eastern black nightshade emerged for the August 7 evaluation at 1 to 4 inches in height and 10 to 15 plants per plot in the untreated controls. All treatments provided 100 percent control.

Trial Comments

For demonstration purposes, the first rep was not planted, and the first two reps were not randomized.

Weed pressure in the experiment was light.

Weed control could not be evaluated on June 14 because there were no weeds present in any treated plots or the untreated controls.

An additional weed control rating was taken on July 23 as weed control by some treatments began to break.

Trial Comments

Common waterhemp size and pressure varied significantly for postemergence applications depending on whether a PRE or EPOST application already occurred.

Treatments 1 & 2 contained large common waterhemp ranging from 10 to 30 & 8 to 25 inches in height, respectively, at the LPOST application timing. Common waterhemp for Trts. 3, 6 & 9 averaged 14 to 17 inches and Trts. 4, 5, 7 & 8 averaged 12 inches in height. Trts. 12, 13 & 14 averaged 8 to 11 inches in height for common waterhemp at the LPOST application timing.

Means followed by same letter or symbol do not significantly differ (P=.05, LSD)Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.Missing data estimates are included in columns:Average=1,3,5,7,9,11,13

Date By Notes6/23/2018 Common waterhemp pressure varied as a result of PRE applications from almost no plants for Trts. 4, 5 & 8-12and from 0.5 to 1 per square ft for Trts. 2, 3, 6 & 7.

Trial Comments

Neither Alite27 nor Callisto are registered for use in soybean at this time.

Common waterhemp pressure is lighter towards the side of the trial with larger plot numbers (i.e. 112, 212 & 312).

Common waterhemp pressure at the POST application varied as a result of control by PRE applications; Little to no common waterhemp pressure was present for Trts. 4, 5 & 8-12 (8-10" height) and larger plants (13-16" ) from 0.5 to 1 per sq. ft. were in Trts. 2, 3, 6 & 7.
