Abstract

Field trails were conducted in 1976–77, 78–79 and 79–80 to estimate losses caused by major pests on main (kharif) and ratoon (rabi) sorghum, by adopting recommended control measures. The shootfly incidence caused substantial loss of grain and fodder in unprotected plots. The ratoon crop suffered more by the pests as compared to the main crop. The average loss of grain and fodder in main and ratoon crop was to extent of 24.7 and 28.9 q/ha respectively. A net profit of Rs. 3405 and Rs. 3169/ha was obtained in main and ratoon crop respectively by using insecticides
