TLDR
None of the neonicotinoids have adverse effect on natural enemies of aphid in okra ecosystem and imidacloprid 17.8 SL@ 50 g a.i. ha -1 was found as a most effective neonicsotinoid insecticide against aphid.
Abstract
An experiment was conducted to observe the efficacy of some neonicotinoidsagainst aphid of okra during pre- kharif season of 2010 and 2011 at Instructional Farm , Bidhan Chandra Krishi Viswavidyalaya. Imidacloprid 17.8 SL@ 50 g a.i. ha -1 was found as a most effective neonicotinoid insecticide against aphid. It recorded least aphid infestation and 84.54 % reduction of population over control. To control aphid populationof okra the other two neonicotinoidsviz., thiamethoxam25WG @ 50 g a.i. ha -1 and acetamiprid 20SP @ 40 g a.i. ha -1 were also found at par with imidacloprid and showed better result than acephate 75WP and dimethoate 30EC. Considering incremental cost ben efit ratio acetamiprid 20SP @ 40g a.i. ha -1 was found most economic over other neonicotinoids . None of the neonicotinoids haveadverse effect on natural enemies of aphid in okra ecosystem.
