24

Increase in the population of a pest following a reduction in the population of natural predators or parasites of the past. Usually the result of a Nonspecific pesticide or unfavorable environmental condition

Pest resurgence

25

Any chemical used to control or kill unwanted pests such as weeds, insects, or fungi.

Pesticide
