摘要
通过几种药剂对水稻立枯病菌的抑菌试验 ,筛选出 2种效果较好的药剂。将这 2种药剂按不同比例配方及不同使用浓度进行抑菌试验和田间试验 ,筛选出防治水稻立枯病混配药剂——— 5 6 %克枯灵可湿性粉剂。其最佳使用剂量为 1 6 7g/m2 。该药对水稻安全、防效显著 ,且比同类产品成本低 8%～ 10 %。
Two effective chemicals (E, F) for controlling rice seedling blight were selected. The control effect of different ratio of E to F and different dosage of E and F mixtures were tested in laboratory and field experiments. A new effective pesticide-56% Kekuling water powder (WP) to control rice seedling blight was formulated. The best dose was found to be 1 67?g/m 2. This was a safe and low cost pesticide, 8%～10% lower than similar pesticides in cost.
