水稻白叶枯病是一种细菌性病害。一般年份发痫田块减产达10—20%,雨水多的年份,发病严重的地块,减产可达50%以上。以控制初侵染源为中心,选用抗病品种和合理的栽培措施,辅以早期药剂防治,可控制病害发生。1.种子处理:50%代森鲅500倍,或10%叶枯净240倍,浸种24—48小时。2.秧田药剂防治:拔秧前可用代森铵或叶枯净防治1～2次,如防两次,则在拔秧前半 Bacterial leaf blight is a bacterial disease. Epilepsy field general block production cut 10-20%, rainy years, the incidence of serious plots, cut down more than 50%. To control the source of initial infection as the center, the selection of resistant varieties and reasonable cultivation measures, supplemented by early agent control, disease control can be controlled. 1. Seed treatment: 50% dendrobium 500 times, or 10% foliar net 240 times soaking for 24-48 hours. 2. Seedling drug control: available before pulling seedling ammonia or leaf dry net control 1 to 2 times, such as anti-twice, then the first half
