Abstract:

Soybean (Glycine max L.) is an important leguminous oil seed crop among all the seed crops of country grown during rainy season. The higher incidence of weed and pests during growth period are one of the important menaces in getting higher yield of crop.A field experiment was conducted during rainy season 2019 at Agricultural Research Station, Banswara (Raj.), India to evaluate bio-efficacy of compatible tank-mix combinations of herbicide and insecticides to manage the weed and insect-pests in crop. The lower weed density and weed dry matter were recorded in combine application of imazethapyr+chlorimuron compared to sole application of imazethapyr and chlorimuron. Tank mix application of imazethapyr 10 SL @ 75 g a.i./ha + chlorimuron 25 WP @ 9 g a.i./ha) with chlorantraniliprole@0.3ml/L. resulted in significantly lowest weed density (33.14/m2) followed by profenofos with imazethapyr + chlorimuron   (36.22/m2) at 30 DAS. These similar results were recorded at 45 and 60 DAS. Application of imazethapyr+chlorimuron with chlorantraniliprole was recorded lowest weed dry matter (11.56 g/m2) and highest weed control efficiency (87.22%) at 60 DAS followed by imazethapyr+chlorimuron with profenofos and significantly superior over rest treatments. Number of leaf roller and caterpillar larvae per meter row length/mrl at one week after treatment was significantly less in treatments involving insecticides. Visual defoliation score was significantly less in treatments involving insecticides than weedy check and sole herbicide.
