3B Exam
3/4/2010
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
Largest Turfgrass Disease Category
FUNGUS Not going to talk about them.
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
Types of WeedsBroadleaf Weeds
Grassy Weeds
Annual weeds
Winter
Summer
Biennials
Perennials
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.
Factors Influencing Weed Control with Soil Applied
Herbicides
Kinds of weeds Application rate Uniformity of application Solubility of herbicide Volatility of herbicide Rainfall or irrigation Soil type Organic matter
Factors Influencing Weed Control with Foliage Applied
Herbicides
Kinds of weeds Application rate Uniformity of application Spray additives Stage and rate of weed or crop growth Loss due to rain or degradation by sunlight Retention on leaves
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
Parts of the Label Brand Name Common Name Chemical Name Type of Pesticide Net Contents Name and Address of Manufacturer Registration & Establishment Numbers
Parts of the Label Signal Words
– Danger– Warning– Caution
Worker Protection Standards Precautionary Statements Statement of Practical Treatment Environmental Statement
Parts of the Label Physical or Chemical Hazard Classification Statement Storage and Disposal Statement Direction for Use
