Entomopathogenic Nematodes - Implementation into Crop Production Systems

Thirty years ago, the idea of using nematodes to control pest populations was vague promise held by the handful of researchers working with these obscure insect parasites. Today, they are no longer a laboratory curiosity but have begun to gain acceptance as environmentally benign alternatives to chemical insecticides.

A hundred different laboratories explore these nematodes and their bacterial symbionts in more than 60 countries from every inhabited continent. Worldwide examples of use of entomopathogenic nematodes in crop production systems show effectiveness against pests that were once thought impossible to control.

Controlling Soybean Cyst Nematode

The Soybean Cyst Nematode. It is a major player in production, and there have been millions of dollars lost to this nematode. The Soybean Cyst Nematode has a very narrow host range.

Current Options for Managing Nematodes Pest of Crops in India

Plant parasitic nematodes can cause damage to almost all kinds of crops. Estimated annual yield losses in the world’s major crops due to plant parasitic nematodes is about 12.3%. In India, recent estimate showed nematode is responsible for about Rs.240 billion yield losses every year.

Judicious use of chemical nematicides could be applied for protection of many crops. Integration of various available practices is one of the current approaches for managing pest problems of crops. Current options for nematode management are cultural practices, physical methods, biointensive nematode suppression, botanicals and sensible use of chemical nematicides.

Considering importance of nematodes in the integrated pest management system, following low input plant protection technologies viz. summer ploughing, soil solarization, organic manuring, crop rotation, adjusting dates of sowing, growing resistant varieties, irrigation management, optimum fertilization, hot water treatment, clean cultivation, green manuring, inter/mixed cropping, judicious use of pesticides, integration of two or more above mentioned methods could be adopted for managing insect pest, diseases including nematodes in the crop production system.

In the review, economically important plant parasitic nematode problems of crops in India and their management options are briefly discussed by dr. Khan.
