Effect of Environmental Factors on the Development of Grain Mold Disease Intensity of Sorghum, Sorghum bicolor (L. Moench)

Among the different weather factors, rainfall and air temperature (max.) were shown significant relation with disease intensity in various cultivars tested. Rainfall was found significant positive regression on CSH-9, and CSV-15 in Akola and CSH-6, CSH-13, CSH-14 and SPV-462 in Parbhani. Air temperature (max.) was found significant negetaive regression in two cultivars namely CSH-14 and CSV-13 in Akola and CSH-13 in Parbhani. In all, tested cultivars at both the centres, intensity of GM disease was mainly dependent on rainfall, alone.
