Question 1

What is 'spray drift' and why is it an environmental concern?

Accepted Answer

The movement of spray droplets or vapour away from the target area, potentially contaminating non-target crops, waterways, or habitats

Answer

A measurement of the distance a spray boom covers in a single pass

Answer

The process by which agrichemicals move into the soil profile

Answer

The pattern of spray deposition on a target surface

Question 2

What is a 'buffer zone' in agrichemical application?

Accepted Answer

A minimum distance from sensitive features such as waterways, neighbours' properties, or conservation areas within which application is restricted

Answer

A zone inside the treated area where application rates must be reduced

Answer

The area between the spray boom and the crop canopy

Answer

The area immediately around the spray operator where PPE must be worn

Question 3

Which agrichemical application practices help minimise the risk of waterway contamination?

Accepted Answer

Observing label buffer zones, applying in calm conditions, and avoiding application before forecast rain

Answer

Applying at higher rates to compensate for potential runoff losses

Answer

Applying only in wet conditions so the product is diluted

Answer

Increasing spray pressure to reduce the time near waterways

Question 4

What is 'leaching' in the context of agrichemical environmental impact?

Accepted Answer

The movement of agrichemicals through soil into groundwater

Answer

The evaporation of agrichemicals from treated surfaces into the air

Answer

The breakdown of agrichemicals by soil microorganisms

Answer

The movement of agrichemicals from leaves into plant tissue

Question 5

What environmental hazard classification on an agrichemical label indicates risk to aquatic life?

Accepted Answer

Environmental Hazard Class 9 — Aquatic Ecotoxicity

Answer

Environmental Hazard Class 3 — Aquatic Ecotoxicity

Answer

Class P (Persistence) only

Answer

Class W (Water) — there is no numerical system for aquatic hazards

Question 6

Why is it important to read the environmental hazard section of an SDS before applying an agrichemical near a stream?

Accepted Answer

It specifies the aquatic toxicity and persistence of the product, informing buffer zone distances and precautions

Answer

It only covers terrestrial animal hazards, not aquatic hazards

Answer

It tells you which fish species are most at risk but does not guide application decisions

Answer

The SDS environmental section is relevant only to disposal, not application
