ABSTRACT
Field experiment was conducted at Nagpur, Maharashtra, during 2014-15 on the management of with seven treatments against major defoliators on soybean (Glycine max L.). Larval population of major defoliators among different treatments were found significant over control. Among these treatments, least number of larvae were recorded in fenvalerate, indoxcarb, emamectin benzoate and spinosad. Minimum per cent foliage damage was recorded in fenvalerate, indoxacarb, emamectin benzoate and spinosad. Lowest number of Chrysoperla carnea was noticed in fenvalerate, spinosad, indoxacarb, emamectin benzoate and whereas, highest number of Chrysopa was recorded in neem seed extract, neem oil and Beauveria bassiana. Maximum yield was found in fenvalerate and it is on far with spinosad, emamectin benzoate and indoxacarb.
Key words :
Emamectin benzoate, Indoxacarb, Soybean, Spodoptera litura, Spinosad, Thysanoplusia orechalsia.
