Question

Which of the following pest control techniques is/are used in IPM?

• A. Use of citronella and neem oil as effective pesticides
• B. Use of genes from Bacillus thuringiensis to eradicate bollworm
• C. Use of Trichoderma harzianum fungus as a fungicide
• D. All of the above

Answer 1

The correct option is D All of the above

IPM emphasises on the growth of healthy crops with the least possible damage to the environment, and encourages natural pest control mechanisms like the use of naturally occurring compounds from plants, animals, fungi and bacteria. For example:
1. Traditional plant products like citronella oil, garlic oil, neem oil, pongamia oil, etc. can be used as effective pesticides which have a fairly broad range and are non- toxic to the rest of the environment.
2. The use of genes from bacteria like Bacillus thuringiensis to eradicate bollworm infecting the cotton plant, through biotechnology.
3. The use of Trichoderma harzianum fungus which is used as a fungicide for the suppression of various disease-causing fungal pathogens.
