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.
