Pesticides and Pest Control Questions
Which of the following is an example of a biosecurity measure in aquaculture?
-
Quarantining new fish before introducing them to the farm
-
Disinfecting equipment and vehicles before entering the farm
-
Using only certified disease-free fish seed
-
All of the above
D
Correct answer
Explanation
Quarantining, disinfection, and using certified fish seed are all examples of biosecurity measures.
Which of the following is NOT a key principle of IPM in aquaculture?
-
Prevention is better than cure
-
Reliance on a single pest or disease management method
-
Integration of multiple pest and disease management strategies
-
Monitoring and evaluation of IPM strategies
B
Correct answer
Explanation
IPM emphasizes the integration of multiple management strategies, rather than relying solely on a single method.
Which agricultural practice involves the use of beneficial insects and other natural enemies to control pests?
-
Biological pest control
-
Chemical pest control
-
Crop rotation
-
Agroforestry
A
Correct answer
Explanation
Biological pest control is an agricultural practice that involves the use of beneficial insects, predators, or other natural enemies to control pests and reduce the need for chemical pesticides.
Which agricultural practice emphasizes the use of natural enemies to control pests and diseases?
-
Biological control
-
Chemical control
-
Physical control
-
Cultural control
A
Correct answer
Explanation
Biological control is an agricultural practice that involves the use of natural enemies, such as predators, parasites, and pathogens, to control pests and diseases in a sustainable and environmentally friendly manner.
Which of the following is NOT a key component of IPM?
-
Monitoring pest populations
-
Applying chemical pesticides
-
Utilizing biological control agents
-
Implementing cultural practices
B
Correct answer
Explanation
IPM emphasizes the use of non-chemical methods to manage pests, such as monitoring, biological control, and cultural practices. Chemical pesticides are used as a last resort when other methods fail to control pest populations.
What is the role of monitoring in IPM?
-
To determine the presence and abundance of pests
-
To identify beneficial organisms in the crop
-
To assess the effectiveness of pest control measures
-
All of the above
D
Correct answer
Explanation
Monitoring in IPM involves regularly assessing pest populations, beneficial organisms, and crop health to make informed decisions about pest management.
What is the purpose of biological control in IPM?
-
To introduce natural enemies of pests into the crop
-
To release genetically modified organisms to control pests
-
To apply chemical pesticides to kill pests
-
To remove pests manually from the crop
A
Correct answer
Explanation
Biological control in IPM involves the introduction and release of natural enemies, such as predators, parasitoids, and pathogens, to suppress pest populations.
Which of the following is an example of a selective pesticide used in IPM?
-
Broad-spectrum insecticide
-
Systemic herbicide
-
Narrow-spectrum insecticide
-
Contact herbicide
C
Correct answer
Explanation
Selective pesticides, such as narrow-spectrum insecticides, target specific pests while minimizing harm to beneficial organisms.
What is the concept of economic threshold in IPM?
-
The pest population level at which control measures are economically justified
-
The pest population level at which crop damage becomes irreversible
-
The pest population level at which chemical pesticides must be applied
-
The pest population level at which natural enemies become ineffective
A
Correct answer
Explanation
The economic threshold in IPM is the pest population level at which the cost of control measures is equal to or less than the value of the crop saved.
Which of the following is an example of a non-chemical pest control method used in IPM?
-
Crop rotation
-
Biological control
-
Chemical pesticide application
-
Tillage
A
Correct answer
Explanation
Crop rotation is a non-chemical pest control method used in IPM to disrupt pest life cycles and reduce pest populations.
What is the importance of integrating multiple pest management tactics in IPM?
-
To enhance the effectiveness of pest control
-
To reduce the risk of pest resistance
-
To minimize the environmental impact of pest management
-
All of the above
D
Correct answer
Explanation
Integrating multiple pest management tactics in IPM enhances pest control effectiveness, reduces the risk of pest resistance, and minimizes the environmental impact of pest management.
Which of the following is NOT a key principle of IPM?
-
Prevention of pest problems
-
Reliance on chemical pesticides
-
Monitoring pest populations
-
Decision-making based on economic thresholds
B
Correct answer
Explanation
IPM emphasizes the use of non-chemical methods to manage pests and relies on chemical pesticides only when necessary.
Which of the following is an example of an integrated pest management (IPM) strategy that can be used to mitigate the impacts of climate change on agricultural pests and diseases?
-
Crop rotation
-
Biological control
-
Resistant varieties
-
All of the above
D
Correct answer
Explanation
IPM is a holistic approach to pest management that emphasizes the use of multiple tactics to reduce pest populations and minimize the use of pesticides. Crop rotation, biological control, and resistant varieties are all examples of IPM strategies that can be used to mitigate the impacts of climate change on agricultural pests and diseases.
Which of the following is an example of the Precautionary Principle being applied in India?
-
The ban on the use of DDT in agriculture
-
The ban on the import of genetically modified crops
-
The requirement for environmental impact assessments for new development projects
-
All of the above
D
Correct answer
Explanation
All of the above are examples of the Precautionary Principle being applied in India.
Which insect repellent is most suitable for preventing bug bites during farm activities?
-
Natural insect repellent
-
Chemical insect repellent
-
Homemade insect repellent
-
No insect repellent
A
Correct answer
Explanation
Natural insect repellents are effective and gentler on the skin, making them suitable for farm stays.
