阜阳市芝麻叶部病害药剂防治研究

Study on Pharmacy Control Sesame Leaf Disease in Fuyang City

针对阜阳市芝麻叶部病害发生较重的情况,设置5种药剂和3种施药次数15种处理的药剂防治试验。调查结果显示,5种药剂防效是施药3次>施药2次>施药1次,施药后7 d防效以枯草芽孢杆菌SC喷雾3次处理最好,施药后14 d以50%己唑醇WG喷雾3次处理、20%硅唑·咪酰胺EW喷雾3次处理、枯草芽孢杆菌SC喷雾3次处理的防效好于其他处理;增产效果、单株蒴数、千粒重与防治次数呈正相关,枯草芽孢杆菌SC喷雾3次处理和28%井岗·多菌灵WP处理的增产效果好于其他处理。

Aiming at the heavier situation of sesame leaf diseases in Fuyang City, the drug control test with 15 kinds of treatments, 5 kinds of pharmaceuticals and 3 kinds of application times were set up. The results showed that control effects of 5 kinds of pharmaceuticals was apply 3 times〉 apply 2 times〉 apply once. Control effect of treatment spray the bacillus subtilis SC 3 times 7 days after application was the best. The control effects of treatments with 50% hexaconazole WG 3 times, 20% silicon oxazole imidazole EW spray 3 times, bacillus subtilis SC spray 3 times 14 days after application were better than other treatments. The results showed that the yield effect, the number of single plant capsule and 1000-grain weight were positively correlated with number of prevention and treatment. The increase production effects of treatment bacillus subtilis SC spray 3 times and 28% Jinggang＇carbendazim WP treatment were better than other treatments.
