IPM of Potato

India has a great diversity of insect pests and pathogens attacking potato. These pests and diseases can damage potato plants by feeding on leaves, reducing photosynthetic area and efficiency by attacking stems, weakening plants and inhibiting nutrient transport; and attacking potato tubers destined for consumption or use as seed. Tubers are heavily damaged in the field and in storage, and this damage causes direct losses to farmers. So, for high productivity, application of chemical pesticides has always been a first choice. But ever increasing resistance of pest to pesticide and residue remains of these pesticides leads to a major concern about human health and other environmental hazards. Therefore, at present the integrated management of pest and diseases is needed for economically sound pest control techniques. A great diversity of pests and diseases attacking potato exists in India due to different agro-climatic zones and their feeding habits.
