Indian mustard is commonly used as a trap crop in cabbage cultivation. Trap crops are planted to attract pests away from the main crop, reducing pest pressure. In this case, Indian mustard attracts pests such as cabbage aphids and caterpillars, thus protecting the cabbage plants from damage.
This practice helps reduce the need for chemical pesticides and promotes integrated pest management (IPM).
Mustard plants release chemicals that are particularly attractive to pests that would otherwise target cabbage, thus safeguarding the main crop.
Trap cropping is an effective method for managing pests without harming the environment.
