ABSTRACT

Experiments were conducted to evaluate efficacy of different pyrethroid alone and in combination with Dimethoate against stem fly of soybean during kharif season of 2011-2012 on field of Department of Agricultural Entomology, Dr. PDKV, Akola. In evaluation study twelve treatments were tested against stem fly Melanagromyza sojae (Zehnt) on soybean. The results revealed that the per cent stem length tunneled due to stem fly was significantly reduced in plots treated with Triazophos 35% + Deltamethrin 1% (36% ready mix formulation) @ 0.09% followed by Triazophos 40 EC @ 0.06% + Deltametrin 2.8 EC @ 0.0028% and Dimethoate 30 EC @ 0.045% were found significantly most effective in minimizing the average per cent infestation of stem fly at 90 days after sowing of soybean. Lastly economics and ICBR were calculated for each treatment.
