| 摘 要： | 对井冈霉素和满穗及其混配剂纹枯宝作为再生稻栽培方式下纹枯病防治剂的可行性进行了田间评价，结果表明，23％满穗悬浮剂15m1／667m2对水稻纹枯病防效和增产效果显著，符合再生稻栽培要求，可在再生稻栽培区推广。10％纹枯宝水剂防治水稻纹枯病在前期有良好的防治效果，虽持效期短于满穗，但成本大大低于满穗，因此在再生稻栽培区是一种较理想的候选药剂。井冈霉素效果较差。

| Abstract: | A field evaluation was carried to test the feasibility of Pulsor,Jinggangmycin and Wenkubao (Pulsor+validamycin) as sheath blight control agents under cultivation system of ratooning paddy,The results showed that twice 15ml applications of 23% Pulsor is the most effective against sheath blight (Rhizoctonia solani) although it is the most expensive.Twice application of 10% Wenkubao indosage of 75 or 100ml gave good control for 15d with much less cost and is recommended to use in the areas of ratooning rice.The control by validamycin is not satisfactory for ratooning rice system. |
