Field trials were conducted to evaluate the effectiveness of seed-dressing aphicides admixed with seed at planting for control of Russian wheat aphid. Eleven Kenyan wheat varieties were tested. Four treatments were evaluated: Gaucho 350FS (imidacloprid) seed treatment; Carbofuran 350ST (furadan) seed treatment; a single foliar application of Brigade (bifenthrin); and an untreated check. Evaluation tests in two locations for two years demonstrated that Russian wheat aphid can be substantially avoided using seed treatment insecticides. Average grain yield gain for the 11 varieties at Njoro, for Gaucho 350FS, Carbofuran 350ST and Brigade treatments was 158.9%, 127.9% and 113.6%, compared with the untreated check, respectively. At Mau Narok average yield gain was 175.2%,146.9 % and 123.1%, for Gaucho 350FS, Carbofuran 350ST and Brigade treatments, compared with the untreated check, respectively. In conclusion, insecticide seed-dressings are effective in control of Russian wheat aphid in Kenya and such treatments can prevent heavy production losses due the pest. Foliar spray treatment with Brigade was not effective due to incomplete protection of the crop.|
