AGRP 1125-Review-Spring 2025

After we apply 2,4 D or Dicamba, we need to rinse the tank to avoid contamination. Detergent is recommended to use.

We need to rotate insecticides with different names and modes of action to prevent insect resistance.

Choose a crop where we cannot practice crop rotations.

Tools or equipment destroy or remove pests from the plant or area. What is the control method?

What is secondary dormancy?

The insect pest population level is tolerable when it is above the ET.

IPM aims to reduce pest damage to an acceptable level and increase production, regardless of environmental damage.

It is an insecticide put into soil or on a plant to protect it from insects that are killed once is touched.

Pesticide is a chemical compound used to control, prevent, kill, suppress, or repel pests.

One of the IPM goals is to eradicate insect pest populations under field conditions.

Fungi can make their own food because they have chlorophyll.

Bioaccumulation is the concentration of a toxin as it moves up through the food chain.

When we use the same insecticide for multiple applications, each application will kill fewer insects.

Contact pesticides are generally at risk for the development of resistance.

Pest density level at which management action should be taken to prevent a pest population from reaching the EIL.

After the EIL is reached, the benefits of applying chemical control will be greater than the cost.

The insect pest population level is tolerable when it is below the ET.

Bt corn and Bt cotton are two genetically engineered pest-resistant plants that are part of genetic control.

Chlorothalonil is a systemic fungicide that effectively controls peanut foliar diseases.

EIL is the smaller number of insects (amount of injury) that will cause yield losses equal to the insect management cost

We have a crop in the field that is injured by a pest but the yield reduction is minimal, how do we call this cultivar?

Choose the second stage of an insect that undergoes complete metamorphosis.

Pecan and peanut are two important GMO crops in the USA

Pesticide is a substance or mixture of compounds used to control, prevent, kill, suppress, or repel pests.

It is an enzyme that catalyzes the breakdown of acetylcholine.

We need to increase or decrease an insecticide rate depending on the insects' number/Acre.

Systemic pesticides are generally not washed off in rain after being absorbed.

A stylet is an anatomical structure found in plant-parasitic nematodes.

The following are steps in the IPM cycle. Choose the correct alternative.

It is a heritable trait that permits a pest to survive exposure to a full field rate of a properly applied pesticide.

It is the stage of an insect that develops in the water before it becomes an adult.

Biorational pesticides are compounds that are less toxic and target specific species and aspects of pest biology.
