This arises from a firm understanding of the relevant IPM concepts for each stage of crop growth, from planting to harvest. - - Integrated Pest Management (IPM) for Rice: GCP/RAS/NET 145. Integrated Pest Management (IPM) is a technique by which farmers encourage the natural enemies of the pests attacking their crops.

In this case IPM is being used on rice production.
