Trap cropping is an agricultural pest management technique in which farmers grow a specific crop around or alongside the main crop to attract harmful insects away from the primary crop. The trap crop acts as a decoy, drawing pests toward itself and reducing damage to the main crop. This method is an important part of Integrated Pest Management or IPM and helps minimize the use of chemical pesticides.

How Does Trap Cropping Work?

Certain pests prefer specific plants over others. Farmers take advantage of this behavior by planting a trap crop that is more attractive to the pests than the main crop. Once the pests gather on the trap crop, they can be controlled through mechanical, biological, or chemical methods without affecting the main field.

Benefits of Trap Cropping

• Reduces pest damage to the main crop.

• Lowers dependence on chemical pesticides.

• Supports environmentally friendly farming practices.

• Helps conserve beneficial insects and pollinators.

• Can improve crop yield and quality.

Common Examples of Trap Crops

• Mustard is planted around cabbage fields to attract aphids and diamondback moths.

• Marigolds grown near tomato crops to help manage nematodes.

• Castor planted around cotton fields to attract tobacco caterpillars.

Trap cropping is a cost-effective and sustainable farming practice that helps farmers protect crops while promoting ecological balance.
