Pesticides and Pest Control Questions

Multiple choice

Which of the following is a natural pest control method used in organic farming?

  1. Using synthetic pesticides

  2. Releasing ladybugs to prey on aphids

  3. Applying chemical fertilizers

  4. Using genetically modified crops
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Releasing ladybugs is a natural and effective way to control aphids, a common pest in organic farming. Ladybugs feed on aphids, helping to reduce their population and protect crops.

Multiple choice

How does the use of integrated pest management (IPM) strategies help reduce the reliance on pesticides and promote sustainable pest control?

  1. By combining multiple pest control methods

  2. By promoting the use of biological control agents

  3. By monitoring pest populations and applying pesticides only when necessary

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

IPM strategies combine multiple pest control methods, promote the use of biological control agents, and monitor pest populations to minimize the reliance on pesticides and promote sustainable pest control.

Multiple choice

What is the term used for the practice of applying fertilizers and pesticides only where and when they are needed?

  1. Variable rate application

  2. Precision application

  3. Targeted application

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Variable rate application, precision application, and targeted application are all terms used to describe the practice of applying fertilizers and pesticides only where and when they are needed.

Multiple choice

Which of the following is NOT a key component of IPM in Integrated Crop Management?

  1. Monitoring pest populations.

  2. Applying chemical pesticides as a primary pest control method.

  3. Utilizing biological control agents.

  4. Implementing cultural practices to reduce pest pressure.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

IPM emphasizes the use of non-chemical methods as the primary means of pest control, reserving chemical pesticides for specific situations.

Multiple choice

Which IPM technique involves the introduction of natural enemies of pests into the ecosystem?

  1. Cultural control.

  2. Biological control.

  3. Chemical control.

  4. Mechanical control.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biological control is an IPM technique that involves introducing beneficial organisms, such as predators or parasitoids, to manage pest populations.

Multiple choice

Which of the following is an example of a mechanical control method in IPM?

  1. Releasing ladybugs to prey on aphids.

  2. Applying neem oil to control insect pests.

  3. Using pheromone traps to disrupt mating.

  4. Handpicking pests from infested plants.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Handpicking is a mechanical control method that involves manually removing pests from plants.

Multiple choice

Which IPM practice involves the use of pheromones to disrupt pest mating?

  1. Biological control.

  2. Cultural control.

  3. Mechanical control.

  4. Chemical control.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pheromone traps and dispensers are chemical control methods that utilize pheromones to disrupt pest mating and reduce pest populations.

Multiple choice

Which IPM technique involves the release of sterile insects to disrupt pest reproduction?

  1. Biological control.

  2. Cultural control.

  3. Mechanical control.

  4. Sterile insect technique.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The sterile insect technique is an IPM method that involves releasing sterile insects into the population to mate with wild insects, reducing the overall pest population.

Multiple choice

Which IPM practice involves the use of resistant crop varieties to reduce pest damage?

  1. Biological control.

  2. Cultural control.

  3. Host plant resistance.

  4. Mechanical control.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Host plant resistance is an IPM technique that involves using crop varieties that are naturally resistant to pests, reducing the need for chemical control.

Multiple choice

Which IPM technique involves the use of natural substances to control pests?

  1. Biological control.

  2. Cultural control.

  3. Chemical control.

  4. Botanical control.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Botanical control is an IPM technique that involves the use of plant-derived substances to repel, attract, or kill pests.

Multiple choice

Which of the following is NOT a prohibited substance in organic farming according to the NOP?

  1. Synthetic pesticides

  2. Synthetic fertilizers

  3. Genetically modified organisms (GMOs)

  4. Natural pesticides derived from plants
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural pesticides derived from plants are allowed in organic farming according to the NOP, as long as they are approved by the program.
