Resp Edassery sir, Upto my knowledge.Imidacloprid will be mixed @ 0.3 ml per ltr water and sprayed on crops. Per acre , around 250 ltrs are required and Imidacloprid 75 ml per acre only required. If it is confidor Super, 0.125 ml/0.150 ml per ltr is required per ltr water, and per acre 30 to 35 ml is required. As said by your shop keeper, ).5 ml super confidor per ltr water is wrong and the bottle showing figures are wright. pl follow company,bottle instructions.
Best wishes, g.p.rao, farmer
