Growsafe Mixing and Loading Agrichemicals 2

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 nozzle size and boom width of the spray equipment

Answer

The type of pest or weed being targeted and the time of year

Answer

The weather forecast and the product's withholding period

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

Excess mixture reduces the effectiveness of the agrichemical over time

Answer

Larger volumes of mixture cause spray equipment to corrode faster

Answer

Preparing excess mixture wastes agitation time and fuel

Question 3

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

Accepted Answer

Surfactants and adjuvants

Answer

Wettable powders and water-dispersible granules

Answer

Suspension concentrates and flowable formulations

Answer

Emulsifiable concentrates

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

Agitation increases the pressure needed for effective spraying

Answer

Agitation speeds up the chemical reaction between different products

Answer

Agitation reduces the toxicity of the agrichemical before application

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

The total volume capacity of the spray tank being used

Answer

The process of cleaning and neutralising the spray tank after use

Answer

The ratio of water to concentrate used to make the spray solution

Question 6

Before beginning to mix any agrichemical, what must you always read first?

Accepted Answer

The label of each product you intend to use

Answer

The weather forecast to check wind speed and temperature

Answer

Your spray records from previous applications in that paddock

Answer

The spray equipment manufacturer's operating manual

Question 7

What is the main purpose of a closed transfer system when loading agrichemicals?

Accepted Answer

To transfer agrichemical from the container to the tank without exposing the operator to concentrate

Answer

To seal the spray tank and prevent evaporation losses during application

Answer

To close off the spray nozzles automatically when the tank pressure drops

Answer

To prevent the spray tank from being accidentally overfilled with water
