Question:

Statement I: The use of biopesticides can overcome the disadvantages of synthetic pesticides.

Statement II: Biopesticides effectively control weeds and pests without causing harm to living organisms.

Options:

Only statement I is correct .

Only statement II is correct .

Both statement I and statement II are correct .

Both statement I and statement II are incorrect .

Correct Answer:

Both statement I and statement II are correct .

Explanation:

The correct answer is Option (3) - Both statement I and statement II are correct.

Statement I suggests that the disadvantages associated with synthetic pesticides can be addressed by using biopesticides. Synthetic pesticides, although effective in controlling pests, often come with drawbacks such as environmental pollution, harmful effects on non-target organisms, and the development of pesticide resistance. Biopesticides, on the other hand, are derived from natural sources such as plants, bacteria, and fungi. They offer a safer and more environmentally friendly alternative to synthetic pesticides. Biopesticides can target specific pests while minimizing harm to beneficial organisms and the ecosystem. By utilizing biopesticides, the negative impacts associated with synthetic pesticides can be mitigated.

Statement II highlights one of the key advantages of biopesticides, which is their ability to control weeds and pests without causing harm to living organisms. Unlike synthetic pesticides, which may have broad-spectrum effects and harm beneficial organisms, biopesticides can target specific pests or weeds while sparing non-target organisms. This selective targeting ensures that the ecological balance is maintained and reduces the risk of harming beneficial insects, birds, animals, and the environment. Biopesticides are designed to be effective against pests while posing minimal risk to other living organisms, making them a sustainable and environmentally conscious choice for pest control.
