Question 1

A technician wants to spray a perimeter treatment but rain is forecast within the hour. What is the BEST decision?

Accepted Answer

Postpone the application to avoid runoff and reduced effectiveness

Answer

Rain shortly after application can wash pesticide into non-target areas and waterways while destroying efficacy.

Question 2

What is pesticide drift?

Accepted Answer

Movement of pesticide through the air away from the intended target site

Answer

Drift is airborne off-target movement of spray droplets or vapors, which can harm people, pets, and the environment.

Question 3

Which condition MOST increases the risk of spray drift?

Accepted Answer

Small droplet size combined with wind

Answer

Fine droplets produced at high pressure stay airborne longer and are easily carried off target by wind.

Question 4

Repeatedly using pesticides with the same mode of action against a pest population is most likely to cause what?

Accepted Answer

Development of pesticide resistance in the pest population

Answer

Survivors of repeated identical treatments pass on resistance traits, so rotating modes of action is essential.

Question 5

Written information about the pesticide, such as label information or required notice

Answer

NYS neighbor-notification and consumer information rules require applicators to supply pesticide information and required notices to occupants.
