GAP Crop Production & Protection 3

Question 1

What does the term 'action threshold' mean in IPM for GAP-certified growers?

Accepted Answer

The pest population level at which intervention is economically justified

Answer

An action threshold is the pest density at which control measures must be implemented to prevent economic loss.

Question 2

Which type of irrigation method is generally considered to reduce the risk of foliar contamination on fresh produce under GAP?

Accepted Answer

Drip or subsurface irrigation

Answer

Drip or subsurface irrigation delivers water directly to the root zone, avoiding direct contact with edible plant parts.

Question 3

Under GAP standards, when must pesticide applicators who apply federally restricted-use pesticides (RUPs) be certified?

Accepted Answer

Always — before applying any RUP

Answer

Federal law requires that restricted-use pesticides be purchased and applied only by certified applicators or persons under their direct supervision.

Question 4

A GAP grower notices that a non-target weed species has developed resistance to a herbicide used repeatedly over five seasons. What is the best corrective action?

Accepted Answer

Rotate to a herbicide with a different mode of action

Answer

Rotating herbicides with different modes of action is the standard resistance management strategy to prevent and address herbicide-resistant weeds.

Question 5

What is the correct disposal method for empty pesticide containers under EPA and GAP requirements?

Accepted Answer

Triple rinsing and then puncturing before disposal according to label instructions
