Question 1

What two pieces of information do you primarily use to calculate how much agrichemical to measure out for a spray job?

Accepted Answer

The application rate on the product label and the area to be treated

Answer

The product label states the required application rate, and combining this with the area to be treated gives you the exact quantity of agrichemical needed.

Question 2

Why is it important to avoid preparing more spray mixture than you need for a job?

Accepted Answer

Leftover spray mixture is difficult and restricted to dispose of legally

Answer

Leftover spray mixture cannot legally be poured down drains or onto bare ground; excess must be managed according to label directions, so preparing only what is needed avoids this problem.

Question 3

In the recommended mixing order for agrichemicals, which type of product is typically added last?

Accepted Answer

Surfactants and adjuvants

Answer

Surfactants and adjuvants are added last because adding them early can cause excessive foaming that prevents other products from dispersing properly.

Question 4

Why is it important to keep the spray tank agitated while mixing agrichemicals?

Accepted Answer

Agitation keeps insoluble particles suspended and ensures an even, consistent mixture

Answer

Without agitation, wettable powders and suspension concentrates settle to the bottom of the tank, resulting in uneven application rates and ineffective pest or weed control.

Question 5

What does the term 'tank mix' refer to in agrichemical application?

Accepted Answer

A combination of two or more products mixed together in the spray tank

Answer

A tank mix combines two or more agrichemicals or adjuvants in the spray tank for simultaneous application, which can save time but requires careful compatibility checking.
