Abstract:
This study the bio-efficacy of chlorfenapyr 240 g/l SC, at four doses viz.,144 ml a.i./ha, 192 ml a.i./ha, 240 ml a.i./ha and 288 ml a.i./ha along with Chlorantraniliprole 18.5% SC @ 30 ml a.i./ha and Profenofos 50 EC 500 ml a.i./ha against Spodoptera litura and Helicoverpa armigera of soybean its safety to natural enemies at during Kharif season of 2016. The chlorfenapyr 240 g/l SC @ 288ml a.i./ha provided optimum control against the Spodoptera litura and Helicoverpa armigera of soybean along with significant increased yield and was at par with Chlorantraniliprole 18.5% SC @ 30 ml a.i./ha against S. litura and H. armigera. At a lower dose chlorfenapyr 240 g/l SC @ 144 g a.i./ha was also effective against Spodoptera and Helicoverapa. chlorfenapyr 240 g/l SC in any dose is quit safe to the important natural enemies such as different spider species, coccinellids and chrysopa associated in soybean.
