In India, pigeonpea grown mainly in the semi-arid tropics and it is a drought-tolerant legume of kharif season. The crop represents about 5 per cent of global legume production, with more than 70 per cent being produced in India. Madhya Pradesh is a leading state in pulse production which contributes 10 per cent of the total pigeon pea production in the country. Bundelkhand region of the state is well known for cultivation of the pulses especially pigeonpea due to prevailing rainfed situation, however its production is usually affected by diseases and pest incidence due to change in certain weather parameters (rainfall, temperature and relative humidity). Keeping in view the above, the relationship of disease and insect incidence in pigeonpea with meteorological parameters was studied in Sagar district of Bundelkhand region which falls in Vindhya Plateau agro-ecological zone. It was noticed that the phytophthora blight disease occurred in the Ist week of August after heavy rains where maximum temperature was 32.8 and relative humidity was 76.5 per cent and maximum mortality was observed during continuous drizzling which continued for 2 to 3 days. Wilt disease incidence was observed at flowering stage of pigeonpea during IInd fortnight of October and it gradually increased with the lack of moisture in the soil. Pod borer incidence of was found maximum in the second week of November when temperature was 31.7 and relative humidity was 60.7 per cent. Pigeonpea yield affected due to occurrence of diseases and pests which largely attributed to variation in the above meteorological parameters.
