What is back-siphoning in the context of pesticide application?

Accumulation of pesticides at the bottom of a tank
Contamination of water supply due to reverse flow
Over-application of pesticides in a specific area
Under-application of pesticides due to equipment failure

The correct answer is: Contamination of water supply due to reverse flow

Back-siphoning is a term used in the context of pesticide application and refers to the reverse flow of contaminated water back into the supply system. This can happen when there is a change in pressure or when equipment failure occurs. Option A is incorrect because accumulation at the bottom of a tank does not necessarily result in back-siphoning. Option C is incorrect because back-siphoning refers to contamination of water supply, not the amount of pesticides applied. Option D is incorrect because back-siphoning is not related to under-application due to equipment failure, but rather contamination of water supply.
