Question

Pest and disease management practices under organic farming include:
A. Fertile soil of high biological activity
B. Minimum amount of pesticide application
C. Protection of natural enemies of pests through habitat management
(D) Disrupting the ecological needs of pests
Choose the correct answer from the options given below:

• A. A, B and C only
• B. B, C and D only
• C. A, C and D only
• D. A, B and D only

Hint:

In organic farming, "Control" is replaced by "Management." The goal is to keep pest populations at a level where they don't cause economic damage, rather than trying to eradicate them entirely using chemicals.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question explores the fundamental principles of organic farming, specifically focusing on how pests and diseases are controlled without the use of synthetic chemicals. Organic farming relies on ecological processes and biological cycles.

Step 2: Detailed Explanation:

• Fertile soil of high biological activity (A): Organic farming emphasizes building soil health. Soil rich in organic matter and beneficial microorganisms (bacteria, fungi) helps plants develop strong immune systems and better root structures, making them naturally more resistant to pests and diseases. Healthy soil is the first line of defense.

• Minimum amount of pesticide application (B): Strictly speaking, organic farming prohibits the use of synthetic pesticides. While some botanical extracts (like Neem oil) are permitted in emergencies, the philosophy is not about "minimizing" synthetic use but eliminating it in favor of natural alternatives. Therefore, statement B is often considered less accurate in the context of pure organic principles compared to preventative ecological methods.

• Protection of natural enemies (C): Biological control is a pillar of organic farming. By maintaining hedges, flower strips, and diverse habitats, farmers encourage the presence of ladybugs, spiders, and predatory wasps that naturally feed on harmful pests.

• Disrupting ecological needs (D): Cultural practices like crop rotation, intercropping, and altering planting dates disrupt the life cycles and resource availability for specific pests. For example, rotating crops ensures that a pest specific to one plant doesn't find its host in the same spot next year.

Step 4: Final Answer:
Organic pest management primarily focuses on preventative and ecological measures (A, C, and D) rather than just minimizing pesticide volume.
