abstract
A field experiment was conducted during rabi, 2016-17 and 2017-18 to evaluate the efficacy of granular insecticides against stem borer and wireworm infesting un-irrigated fodder sorghum. An experiment was conducted at Agricultural Research Station, Anand Agricultural University, Arnej, Ta. Dholka, Dist. Ahmedabad. For the purpose different seven granular insecticides available in the market were applied in the soil along with seed and basal application of the fertilizer, while in case of seed treatment insecticide were applied to seeds and treated seeds were sown after proper drying. Among the tested insecticides seed treatment with thiamethoxam 30 FS @ 8 ml/kg seeds was found very good treatment in protecting the crop against stem borer and wire worm by recording maximum initial plant population and plant population at harvest, minimum reduction in plant population, minimum dead heart (%) and maximum dry fodder yield (kg/ha). It was followed by seed treatment with imidacloprid 600 FS and granular application of fipronil 0.3% G in soil in their efficacy.
