How do you use herbicides to slow the development of resistant weeds? - CORRECT
ANSWER: 1.) Making fewer herbicide applications
2.) Using herbicides that have different modes of action 3.) Mowing to remove flowers before seeds form

is a control method that golf course managers use to force red imported fire ant colonies to less disturbed areas. The more times areas are mowed, the less time fire ants have to establish colonies

CORRECT ANSWER: 1.) Crabgrasses
2.) Goosegrass
- The best time to control these grasses is late winter/early spring
What are 3 types of organisms that are used in biological control of turf insects? -
CORRECT ANSWER: 1.) Predators
2.) Parasites 1 / 4
3.) Pathogens
What are 3 ways to find turf insects in the soil? - CORRECT ANSWER: 1.) Scouting 2.) Sampling 3.) Monitoring
What are 4 pests that might cause root damage to turf? - CORRECT ANSWER: 1.)
Japanese beetle 2.) Mole cricket 3.) Masked chafer 4.) Green june beetle
What are Bactericides? - CORRECT ANSWER: Chemicals that are used for control of
bacterial diseases
What are Parasites? - CORRECT ANSWER: Nematodes that search out insects and
enter their bodies through natural openings or by drilling through the skin and once inside the insect, the nematodes release bacteria that kill the pest within hours
What are some of the basic principles of Integrated pest management? - CORRECT ANSWER: 1.) PREVENTION: Produce healthy plants that resist plants: (Selecting healthy plants, using certified seed, providing good growing conditions, and making a good match between the plant and the site) 2.) MONITOR AND IDENTIFY THE PEST: Identify the problem: (Finding out whether the damage to a particular plant is caused by a pest or by an environmental condition such as freezing or drought and always determine the exact pest that you are dealing with) 3.) SET ACTION THRESHOLDS: Expect some pests and tolerate some damage: (Deciding how many pests and how much damage to tolerate)
4.) CONTROL: Use pesticides as a last choice-Not a first choice
What are some of the ways to control Pythium blight? - CORRECT ANSWER: 1.)
Provide good surface and subsurface drainage 2.) Removal of shrubs, tree limbs, etc., to increase air movement and light penetration will improve conditions commonly associated with chronic problems with Pythium blight 3.) Installing fans near bent grass putting greens will increase air circulation and reduce leaf wetness 4.) Minimize nitrogen applications to cool-season turf grasses when weather conditions are favorable for Pythium development 5.) Fungicide treated seed has improved control of damping-off and seeding blight 6.) Fungicide provides good control when applied on a preventative basis during conditions that favor disease development
What are some of the ways to control Spring dead spot? - CORRECT ANSWER: 1.) In
areas prone to harsh winters, select less susceptible cultivars. Bermuda grass cultivars with good cold tolerance also tend to be more resistant to spring dead spot 2 / 4
2.) Aerify and dethatch regularly 3.) Stop nitrogen applications to bermuda grass 6 weeks prior to the expected rate of dormancy 4.) Use fertilizer such as ammonium sulfate
What are some turf symptoms that would lead you to test for Nematodes? - CORRECT ANSWER: Infested areas tend to wilt prematurely, even when adequate soil moisture is available and short, stunted, and brown root systems from excessive feeding damage
What are some ways to control Brown Patch? - CORRECT ANSWER: 1.) Good
surface and subsurface drainage 2.) Avoid excessive irrigation. Irrigate early (before sunrise) to reduce duration of leaf wetness 3.) Promote air circulation by pruning or removing trees and shrubs or installing electric fans around putting greens 4.) Avoid high nitrogen fertilization, especially during warm weather 5.) Apply preventative fungicides in late spring when night temperatures stay above 60 degrees
What are some ways to control Dollar spot? - CORRECT ANSWER: 1.) Select
turfgrass cultivars that exhibit resistance to dollar spot 2.) Fertilize to avoid nitrogen deficiencies and to reduce disease severity 3.) Irrigate during early morning hours to limit high periods of high humidity and leaf wetness 4.) Mow at correct height
What are some ways to control Fairy ring? - CORRECT ANSWER: 1.) Remove stumps
and other wood material from the root zone before establishing a turf grass area. Fairy rings will develop where wood is left in the root zone 2.) Deep tilling and application of an approved fumigant have shown limited success 3.) Symptoms may be masked by adequate irrigation or fertilization with nitrogen and/or iron
*Fairy rings are very difficult to control
What are some ways to control Gray leaf spot? - CORRECT ANSWER: 1.) Mow at
recommended height. Infrequent mowing and high cutting height may favor disease 2.) Improve air movement and light penetration in areas prone to chronic infections 3.) Irrigate only during early morning hours to minimize duration or leaf wetness 4.) Fungicides provede short-term (2-3 week) suppression of the disease in lawns
What are some ways to control Pink snow mold? - CORRECT ANSWER: 1.) Maintain
balanced fertility levels and optimal soil pH based on soil tests 2.) Mow frequently at appropriate cutting heights 3.) Avoid fertilization during periods of slow turf grass growth in winter

What are the 2 different kinds of metamorphosis that insect pests undergo? - CORRECT ANSWER: 1.) Gradual metamorphosis: Nymphs (young stages) of insects that undergo this look like small versions of the adult 2.) Complete metamorphosis (most common type of development among turf grass pests): The young stages of insects that undergo this look very different from the adults before before they become pupae and change into adults
What are the 5 cultural practices that change the environment for the pathogen? -
CORRECT ANSWER: 1.) Irrigation
2.) Air flow 3.) Drainage 4.) Compaction 5.) Thatch
What are the different components of the disease pyramid? - CORRECT ANSWER: 1.)
Susceptible host 2.) A disease causing pathogen 3.) An environment favorable for infections and development of the disease 4.) Time for the disease to develop
What are the guidelines for use of post emergence herbicides? - CORRECT ANSWER:
1.) Do not apply post emergence herbicides to newly seeded grass until it has been mowed at least 3 times 2.) Wait 4 to 6 weeks before applying herbicide to a newly sodded area 3.) Do not apply when rain is expected 4.) Try to avoid mowing a treated area for at least 3 days after application 5.) Wait 3 to 4 weeks before seeding bare spots left by killed weeds. Do not seed until the area has received rain or irrigation to break down any herbicide remaining in the soil
What are the guidelines for use of pre emergence herbicides? - CORRECT ANSWER:
1.) You may need to wait 2 to 4 months before it is safe to reseed. Read the label 2.) Do not use a pre emergence herbicide before laying sod or at the time of turf grass seeding unless indicated on the label 3.) Do not add a surfactant or wetting agent to a pre emergence herbicide unless indicated on the label 4.) Wait until after new turf grass seedlings have been mowed 3 or 4 times before applying a pre emergence herbicide 5.) Return clippings to the turf grass area for 2 to 3 weeks after the herbicide application to give time for any herbicide absorbed by the leaves to be returned to the thatch layer and contribute to the chemical barrier 6.) Try to avoid use of pre emergence herbicide on thin, weak, or damaged turf

shaped gray or tan lesions with dark brown borders are present on infected leaves
