On the basis of various cultural methods of control for individual pests of sorghum, as also resistant cultivars and multiple pest resistant sources, an operational integrated pest management strategy was evolved. It is recommended that stubbles, stalks, threshed earheads and trash should be consumed/destroyed or burnt before the onset of the next season preferably by the end of March. The sowings in kharif (rainy season) should commence with the onset of monsoon to avoid damage by shootfly, midge and earhead bugs. Sowing date-cum-varietal approach i.e., uniform date of planting of varieties and hybrids of similar maturity (CSV-7, CSV-8, CSH-9, IS 2205 and ICSV-197) in midge endemic area need to be adopted. Crop sown late in kharif and early in rabi is prone to shootfly. This serious problem can be overcome by planting resistant varieties, viz., SPH-196, SPH-225 and CSH-8R. Sowing of available high yielding, early maturing and insect resistant/tolerant varieties or hybrids, viz., CSV-4, CSV-5, CSV-6, CSV-7, CSV-8, CSH-9, E 201, E 202, E 303, P 297, P 500, E 601, P 311, SPV 102, P 37, P 151, E 501, AKSS-SSV-3, HES-4 and CO-26, with the onset of monsoon will reduce the damage due to major pests to a large extent. Cultivars P 37, P 151, E 501, HES-4 and AKSS-SSV-3 can be grown without plant protection.
