3A TURFGRASS PEST MANAGEMENT EXAM LATEST
REAL EXAM 200+ QUESTIONS AND CORRECT ANSWER|
AGRADE
Why is it important to use both short term suppression and long term suppression
tactics in pest management? - ANSWER: Short term suppression - offers a quick fix
but the pest population will rebuild.
Long term suppression - maintenance must be used to reduce pest populations
permanently
plant resistance - ANSWER: Varieties of grass containing endophyte fungi are one
example
Mechanical and physical resistance - ANSWER: Includes hand removal, traps, barriers
and repellents
Cultural control - ANSWER: includes raking, thatch removal and aeration
Give one example of a weed situation that can be managed with hand removal
techniques - ANSWER: In a new stand of grass, hand removal of weeds may be
necessary to prevent damage to the young grass plants
explain why turf cannot at the same time benefit from biological control methods
and be pest free - ANSWER: there must be a low level of pest or prey insects for the
predators to feed on
How can you help maintain existing populations of beneficial organisms in a turf
stand? - ANSWER: by making pesticide applications only when needed
Are microbial insecticides best used for short term suppression or long term
maintenance of pest populations? Why? - ANSWER: Long term maintenance.
Microbial insecticides are slower acting and do not kill all of the pest at once, which
allows there to be food for other beneficial organisms.
List four ways to classify pesticides - ANSWER: Type of pest
Pesticide chemistry
Mode of action
Pesticide formulation
Broad-spectrum pesticide - ANSWER: Can be used to control several pests, but more
likely to be hazardous to non target organisms.
Residual pesticide - ANSWER: Good for use when the goal is to reduce the number of
applications required to control persistent pests
, Systemic herbicide - ANSWER: Superior in treating persistent perennial weeds, kills
both aboveground and below ground parts of the plant
Contact herbicide - ANSWER: Does not kill the underground plant parts
Explain why keeping track of degree day accumulations is more useful for monitoring
pest activity than going by calendar dates - ANSWER: Insects, diseases and weeds
develop based on heat units. The accumulation of heat units varies from year to year
Explain how knowing the species or variety of turf grass in a stand can help in pest
diagnosis - ANSWER: Certain diseases and insect pests will affect certain species of
turf grass and will not affect others
What three categories of grass species in the United States and Canada? Which is
Michigan, and why? - ANSWER: Cool season, transition, warm season
Cool grass in Michigan
List examples of grass species in Michigan - ANSWER: Kentucky bluegrass
Perennial ryegrass
Creeping bent grass
Does the rate of photosynthesis increase or decrease as the temperature increases?
How does the temperature stress grass plants? - ANSWER: Food production
decreases but the amount of oxygen increases as the temperature gets higher. This
causes the plant to use stored energy at higher temperatures.
Most turf grasses grow best in shady locations? TF - ANSWER: False
How does soil PH affect the availability of nutrients to turf grass and other plants? -
ANSWER: If the PH is too high or too low, certain nutrients may be present in the soil
but will not be soluble and therefore can't be used by plants
Nitrogen (N) - ANSWER: Turfgrass uses large quantities of this nutrient, which may
be lost through leaching
Phosphorus (P or P2O5) - ANSWER: This nutrient is important for root development,
maturation and seed production, and is rarely deficient in most Michigan soils.
Potassium (K or K2O) - ANSWER: This is an important nutrient for rooting and
improves turf grass tolerance to climate stress, routine applications of it are
beneficial to turf grass
Micronutrients - ANSWER: Used in plants in relatively small amounts
Explain how to correct for iron (Fe) deficiency in turf. - ANSWER: in short term, by
applying an iron-containing fertilizer. In long term by lowering the PH in soil.
