Assessment of yield loss caused by powdery mildew disease in mungbean

An experiment was conducted at the Instructional Farm of Agronomy, College of Agriculture, JAU, Junagadh during Kharif, 2015. The yield loss caused by powdery mildew disease was recorded on three treatments i.e. application of propiconazole @ 0.025%, water sprays and untreated control under field conditions. Out of three treatments, lower disease intensity (18.5%) and higher seed yield (1242 kg/ha) was recorded in protected plots as compared to untreated control plots where disease intensity was 68.0% and seed yield was 709 kg/ha. With the application of propiconazole, 42.9% seed yield could be saved with the reduction of disease intensity by 72.8%. Whereas, the application of water saved 5.7% seed yield with reduction of disease intensity by 13.8%.
