Abstract:
The study entitled “Compatibility of Herbicides Mixed with Insecticides in soybean (Glycine max (L.) Merrill)†was conducted in rainfed condition under “All India Co-ordinated Research Project on soybean at R.A.K. College of Agriculture, Sehore (M.P.), during kharif 2014. Experiment was laid out in randomized block design with three replications. The treatments included rynaxypyre 20SC @ 120g a.i./ha (T1), indoxacarb14.5SC @ 87g a.i./ha (T2), quinalphos25EC @ 150ga.i./ha (T3), imazethapyr10SL @ 100g a.i./ha (T4), quizalofop-p-ethyl 5EC @ 50g a.i./ha (T5), rynaxypyre 20SC @ 120g a.i./ha + imazethapyr10SL @ 100 ga.i/ha (T6), rynaxypyre 20SC @ 120g a.i/ha + quizalofop-p-ethyl 5EC @ 50 g a.i./ha (T7), indoxacarb14.5SC @ 87g a.i./ha+imazethapyr10 SL @100g a.i./ha(T8), indoxacarb14.5SC @ 87g a.i./ha +quizalofop-p-ethyl 5EC @50g a.i./ha (T9), quinalphos 25EC @ 150g a.i./ha + imazethapyr10 SL @ 100 g a.i./ha (T10), quinalphos 25EC @ 150g a.i./ha + quizalofop-p-ethyl 5EC @ 50g a.i./ha (T11) and untreated check (T12). Among the monocot weeds Echinochloa crusgalli Link., Degiteria sanguinalis, Dinebra arabica, Cyperus rotundus Linn. and Commelina benghalensis while the dicot weeds Acalypha indica Linn., Eclipta alba, Caesulia axillaris Roxb., Digera arvensis, Corchorous acutangulus and Phyllanthus niruri were observed in the field. Application of indoxacarb 14.5 SC @ 87 g ai/ha + imazathapyr 10 SL @ 100g ai/ha gave lowest weed dry weight and higher weed control efficiency (75.03%). Application of imazathapyr 10SL@ 100g ai/ha alone or in combination with insecticides viz. indoxacarb, rynyxypyre and quinolphos recorded less weed dry biomass and increased weed control efficiency, imazathapyr controlled both dicot and monocot weeds. Application of quizalofop-p-ethyl 5EC @ 50g ai/ha alone and in combination with insecticides effectively controlled the monocot weeds especially grasses viz. Echinochloa crusgalli Link. Degiteria sanguinali and Dinebra arabica.
