What are some of the basic principles of Integrated pest management? - (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 should you do in an IPM program? - (ANSWER)Produce healthy plants that can resist
pests
What is Phytotoxicity? - (ANSWER)A toxic effect by a compound on plant growth
Which method will NOT help monitor cutworms? - (ANSWER)Pitfall traps
What is Bacillus thuringiensis (Bt) ? - (ANSWER)A common bacterium that kills many types
of caterpillars
When should you apply an insecticide? - (ANSWER)When the insect is at its most vulnerable
stage
What is the Milky spore disease? - (ANSWER)A bacterial disease that is caused by the
bacterium, Bacillus popilliae, and kills Japanese beetles
,What do you do to control fire ants? - (ANSWER)Use a combination of broadcast bait and
mound treatments
Sod webworms... - (ANSWER)Spin silk webbing near the soil in turf
An insecticide applied to control white grubs... - (ANSWER)Should be watered in to reach the
soil
Mole crickets... - (ANSWER)Have only one generation per year
What are the 2 different kinds of metamorphosis that insect pests undergo? - (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
How do Chinch bugs damage turf? - (ANSWER)They feed in clusters and damage first appears
as circular patches of yellowing turf that resemble drought injury and large infestations of the
southern chinch bug may completely kill St. Augustine lawns.
What are 4 pests that might cause root damage to turf? - (ANSWER)1.) Japanese beetle
2.) Mole cricket
3.) Masked chafer
4.) Green june beetle
How does frequent mowing impact fire ants? - (ANSWER)Frequent mowing 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
,What are 3 ways to find turf insects in the soil? - (ANSWER)1.) Scouting
2.) Sampling
3.) Monitoring
What are 3 types of organisms that are used in biological control of turf insects? -
(ANSWER)1.) Predators
2.) Parasites
3.) Pathogens
Why should some insecticide formulations be watered in? - (ANSWER)Most soil insecticides
for control of white grubs or bill bugs need to be watered in because when the soil is dry, insects
like what grubs and mole crickets burrow deeper into the soil and are hard to control. Also,
irrigating before the pesticide is applied helps move these insects closer to the soil surface where
they are more likely to encounter the insecticide
What is Scouting? - (ANSWER)Looking for destructive turf grass insects and identifying them
What is Sampling? - (ANSWER)Selecting a pest that is appropriate for the location and habits
of the pest
What is Monitoring? - (ANSWER)Knowing whether the pest is causing enough problems to
justify control
What is an Endophyte? - (ANSWER)A fungus that lives within the plant
What are Parasites? - (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 is a situation where a broad spectrum, non-selective herbicide could be used on turf? -
(ANSWER)When your grass is basically all weeds or you are trying to kill the dead grass to put
new sod
When would weather conditions cause herbicide failure? - (ANSWER)If the weather is too hot,
too dry, or too cold
How do you use herbicides to slow the development of resistant weeds? - (ANSWER)1.)
Making fewer herbicide applications
2.) Using herbicides that have different modes of action
3.) Mowing to remove flowers before seeds form
When is the best time to control biennial weeds? - (ANSWER)The best time to control them is
in their first year of growth
What are 2 summer annual grasses and when is the best time to control them? - (ANSWER)1.)
Crabgrasses
2.) Goosegrass
* The best time to control these grasses is late winter/early spring
What are three problems that could cause failure of pre emergence herbicides? - (ANSWER)1.)
Applying herbicide after weed has emerged
2.) Thick thatch
3.) Too much sunlight causing the herbicide to break down
What is the best approach to control undesirable perennial grasses? - (ANSWER)The best
approach is to spot-treat the infested area of grass With a selective or nonselective, systemic
(translocated herbicide
