Abstract

In 1992 and 1993 insecticide, trials were carried out in two locations in Lao PDR to compare the effectiveness of four insecticides (imidachloprid, benfuracarb, carbosulfan, furathiocarb) applied in seed treatment before sowing , and three modes of application of imidachloprid (powder, coating, pelting) in the control of early cotton pests. The results showed that such seed treatment could accelerate the plant emergence and reduced the rate of damping-off. All the insecticides showed an effect against cotton aphid, leafhopper, whitefly, scale insect and grasshopper when compared to an untreated check, but variations in the level of efficiency were registered according to the active ingredients and the pests. Overall, imidachloprid was the most effective, with the longer residual effect.
