Question: Growing a non-host crop in between susceptible crops is an example of nematode control using which method?
Options:
Physical method
Mechanical method
Biological method
Cultural method
Growing a non-host crop between susceptible crops is a classic example of a cultural control method for managing nematode populations. Cultural control methods involve modifying the cropping system or environment to make it less favorable for pests.
• How crop rotation works:
Starves nematodes: Nematodes are often host-specific, meaning they can only feed and reproduce on specific plants. When a non-host crop is planted, the nematodes are unable to feed and their population decreases due to lack of food and reproduction.
Disrupts life cycle: Crop rotation can disrupt the life cycle of nematodes, preventing them from completing their development and reproduction.
Reduces nematode pressure: By reducing nematode populations, the overall pressure on subsequent susceptible crops is reduced, leading to healthier plants and potentially higher yields.
