Abstract

The bio-efficacy of imidacloprid seed treatment against leafhopper and thrips of groundnut was studied during kharif (23rd to 42nd standard week) and summer (5th to 23rd standard week) cropping seasons of 2010 and 2011. The six different concentrations viz., 0.5, 1.0, 2.0, 3.0, 4.0 and 5.0 g a. i. kg-1 were tested for their bio-efficacy. A modified sweep net method was followed to record the leafhopper and thrips populations. Seed treatments with imidacloprid @ 2.0 to 5.0 g a. i. kg-1 were found most effective in reducing the insect population. However, seed treatment with imidacloprid @ 2.0 g a. i. kg-1 may be included in integrated pest management (IPM) package for groundnut from environmental safety point.
