Control of Rice Gall Fly by Water-Surface Application of Granular Insecticides with Special Reference to Timing of Application

Abstract

Studies were made to test the efficacy of four granular insecticides in four timings of application for the control of the rice gall fly. Phorate and carbofuran were equally effective in checking the incidence of gall fly. The commencement of the first applica. tion on 15th. 20th and 25th days after planting gave better check on silver shoot infes tation irrespective of insecticides.
