试验示范结果表明,叶锈特对小麦叶锈病防病保产效果好,残效期长,用药量低,内吸传导性能强,使用方法多,是目前防治该病较理想的农药品种。在冬小麦播种期,用叶锈特湿拌、浸种和干拌处理种子,对叶锈病均有显著防治效果,其中以种子重量的0.03～0.035％剂量湿拌处理方法为好,防病效果在90％以上,保苗效果显著,可基本上控制整个秋苗期叶锈病的为害。防治成株期叶锈病,应掌握在早期病轻时施药,方可求得最大防效。一般在小麦挑旗期,病情基数低时,采用叶面喷雾和土壤浇灌方法,每亩50克原药,施用一次,防病效果在90％以上,保产效果显著,可控制整个成株期叶锈病的为害。也可用超低容量喷雾方法。
Experimental results show that the leaf rust on leaf rust prevention and protection of wheat is good, long residual period, low drug consumption, strong absorption performance, the use of more, is currently the best control of the disease pesticide varieties. In the winter wheat sowing period, the treatment with leaf rust, wet soak and dry mixing seeds had significant control effects on leaf rust, of which 0.03 to 0.035% of the weight of the seed was treated with a wet mixing method, and the disease prevention effect was 90% % Or more, Paul seedling effect is significant, can basically control the entire autumn seedling leaf rust damage. Prevention and treatment of leaf rust in adult plant, should be mastered in light of early disease application, before the maximum control effect. Generally in the wheat flag period, the condition of a low base, the use of foliar spray and soil irrigation methods, 50 grams of the original drug, applied once, disease prevention effect of more than 90%, the yield effect is significant, can control the entire adult stage Leaf rust damage. Can also be used ultra-low volume spray method.
