Question

All of the following is the part of IPM(Integrated pest management) except
A. Use of resistant varieties
B. Use of crop rotation
C. Biological and mechanical control of pest
D. Regular use of high dose of pesticides from beginning to end of crop

Answer 1

Hint: IPM is an ecosystem-based approach that focuses on the long-term prevention of or harm to pests through a mix of strategies such as biological protection, manipulation of environments, modification of cultural practises and the use of resistant varieties.

Complete Answer:
Only after testing shows that they are required according to existing guidelines are pesticides used, and treatments are made with the objective of eliminating only the target organism.
Pest control products are chosen and implemented in a way that minimises threats to human health, beneficial and non-target species, and the environment. Pests are species in our fields and orchards, habitats, or wildlands that affect or interfere with desirable plants, or affect homes or other structures.

- Organisms that affect human or animal health also include pests. Pests may be disease-transmitting or just a nuisance.
- Pests may include plants (weeds), vertebrates (birds, rodents, or other mammals), invertebrates (insects, ticks, mites, or snails), nematodes, disease-causing pathogens (bacteria, viruses, or fungi), or other unwanted species that could affect the quality of water, animal life, or other parts of the environment.
- Biological controls: Biocontrol is the use of natural enemies.
- Cultural control: Cultural controls are behaviours that reduce pest management, reproduction, dispersal and survival.
- Mechanical and physical controls: Mechanical and physical controls destroy the pest directly, block the pests or make the atmosphere unsuitable for it. Traps for mice are examples of mechanical controls.
- Chemical control: The use of pesticides is a chemical regulation. In IPM, pesticides are used only when appropriate and in conjunction with other methods for more efficient, long-term control. Pesticides are chosen and administered in a manner that minimizes their potential harm to humans, non-target species and the environment. With IPM, you will use the most selective pesticide that does the job and is best for other species and for air, soil and water quality.

The correct answer is option(D) Regular use of a high dose of pesticides from beginning to end of the crop.

Note: With IPM, you take steps to prevent pests from being a problem, such as growing a healthy crop that can withstand pest attacks, using disease-resistant plants, or coating cracks to prevent the entry of insects or rodents into a house. Using IPM means you'll look at environmental factors that impact the pest and its ability to survive, rather than just removing the pests you see right now. You can create conditions that are unfavourable for the pest, armed with this knowledge.
