CGM Pest Management & Integrated Pest Management (IPM) 3

Question 1

What does the signal word 'DANGER' on a pesticide label indicate about the product?

Accepted Answer

The pesticide has the highest relative acute toxicity to humans among the three signal word categories

Answer

The pesticide is approved for use only by certified applicators

Answer

The pesticide poses extreme risk to non-target wildlife and aquatic organisms

Answer

The pesticide is classified as a restricted-use product requiring a special permit

Question 2

What is the primary difference between a contact herbicide and a systemic herbicide?

Accepted Answer

Contact herbicides kill only the tissue they directly touch while systemic herbicides translocate throughout the plant

Answer

Contact herbicides are applied to soil while systemic herbicides are foliar-applied

Answer

Contact herbicides are synthetic compounds while systemic herbicides are organic

Answer

Contact herbicides require multiple applications while systemic herbicides work after a single treatment

Question 3

Which biological control organism is widely used to control Japanese beetle grubs in turfgrass soil?

Accepted Answer

Heterorhabditis bacteriophora (entomopathogenic nematode)

Answer

Trichoderma harzianum (biocontrol fungus)

Answer

Beauveria bassiana (entomopathogenic fungus)

Answer

Bacillus subtilis (plant-growth-promoting bacterium)

Question 4

What is the primary advantage of using spot treatment rather than broadcast pesticide application?

Accepted Answer

Spot treatment reduces total pesticide use by targeting only the areas where pests are present

Answer

Spot treatment is always less expensive per treated acre than broadcast methods

Answer

Spot treatment consistently provides faster control results than broadcast application

Answer

Spot treatment is required by EPA regulations for all turf pesticide applications

Question 5

Which of the following is classified as a mechanical or physical pest control method in IPM?

Accepted Answer

Installing yellow sticky traps to monitor and capture flying insects

Answer

Applying a granular insecticide to control soil-dwelling pests

Answer

Inoculating turf soil with beneficial entomopathogenic nematodes

Answer

Applying a biological fungicide to suppress turf diseases

Question 6

Under IPM principles, when should a chemical pesticide application be considered as a control measure?

Accepted Answer

Only when pest populations or damage levels exceed the established action threshold

Answer

Immediately upon detecting any pest presence, regardless of population size

Answer

On a predetermined calendar schedule to prevent pest populations from building up

Answer

Whenever a new pest species is first identified in the managed landscape

Question 7

Which of the following best describes 'cultural control' as applied in an IPM program for turfgrass?

Accepted Answer

Adjusting mowing height, irrigation frequency, and fertilization to promote turf health and reduce pest pressure

Answer

Using imported beneficial insects to suppress native pest populations

Answer

Applying soil fumigants to eliminate all soil-dwelling organisms before planting

Answer

Installing underground barriers to prevent pest movement between turf zones
