Turfgrass Management Turf must have proper care and
management and timely pest control to be attractive, have good color, and be free of weeds, insects and diseases.
Turfgrass management includes selecting the right grass, mowing, watering, fertilizing, and thatch control.

Turfgrass Problems Determine the kind of grasses
involved. Find out why the problem occurred. Determine if the problem is best
corrected by management practices, soil modification, or pesticides.

Turfgrass Problems Check to see if a chemical is labeled
both for turfgrass species and disease. Recommend good cultural practices
that will assist in turfgrass recovery.

Preventive Disease Control
Water properly Control thatch Mow to the proper height Mow grass frequently Do not restrict air movement Use blends of grasses Provide good drainage

Preventive Disease Control
Fertilize properly Follow a insect and weed control
program Do not plant grasses that are not
adapted to your area.

How do you Diagnosis??1. Identify the turf grass
2. Determine the weather conditions before and during disease development
3. Look at the soil structure and fertility
4. Review cultural and chemical management practices
5. Determine the overall distribution of the problem

How do you Diagnosis?6. Observe symptoms on individual plants
7. Use reference materials

WEEDS Any plant can be considered a weed if
it is growing where it is not wanted.

Good Weed Control Program
1. Identify the desirable turfgrass
2. Identify the existing weeds
3. Combine pest control with good management practices

Weed Control Granular formulations are effective for
preemergence herbicides. Liquid formulations are better for
postemergence control where foliar coverage is needed.

Broadleaf Weed Control Spring and fall applications of
postemergence herbicides normally give satisfactory control and reduce the possibility of damage to nontarget plants.

Grassy Weed Control Control of annual grasses is best
achieved with preemergence herbicide for general infestations and spot treatment with postemergence herbicides for localized infestations.

Managing Insects Inspect all lawn and turf areas on a regular
basis Learn how to ID important turf insect and
their damage Develop a sound pest management strategy Select and apply insecticides carefully and
only when necessary Evaluate the success of the management
program

Minimizing Pesticide Hazards
Make sure you are at the right location Do not allow children or pets to remain in the area
being sprayed. Check neighboring areas for pets or people that
may come into contact with drift Remove toys, pet food dishes, birdfeeder, etc. Avoid spray objects such as park benches or patio
furniture. Avoid fish ponds, bird bathes, and other water
features

Minimizing Pesticide Hazards
Observe pesticide label restrictions Sweep or rinse away all spills Secure all pesticide containers or
spray apparatus before moving
