Efficacy of insecticides as seed treatment for management of termites in Chick pea

The field studies on bio-efficacy of imidacloprid 600 FS as seed treatment for the control of termites on chick pea and compared with chlorpyriphos 20 EC. Significantly lower plant damage was observed in seed treatment with imidacloprid 600 FS @ 1.2 and 1.5 g a.i./kg seed and was comparable with chlorpyriphos 20 EC @ 2.0 g a.i./kg. The analysis of two years trials showed that grain yield was significantly higher in imidacloprid 600 FS @ 1.2 and 1.5 g a.i./kg seed (1367.62 and 1381.12 kg/ha) which was at par with chlorpyriphos 20 EC @ 2.0 g a.i./kg seed (1389.50 kg/ha). Higher % yield increase over control and avoidable yield losses were recorded in upper doses of imidacloprid 600 FS and chlorpyriphos 20EC and net returns over control, these treatments were also better. Thus, it may be concluded that seed treatment with imidacloprid 600FS @ 1.2 g a.i./kg seed can be used effectively for the control of termites in chick pea.
