近年来,我省小麦的纹枯病逐年加重。锈病重新抬头,自粉病发病面积扩大,赤霉病在部分地方流行,麦蚜虫发生面广量大,它们已成为小麦增产丰收的严重障碍,各地应引起重视,采取措施加强防治。纹枯病的防治应以早播、连作、杂草多、氮肥偏高、品种感病强的麦田为重点防治对象。分蘖末期病株率达5%、拔节期病株率达20～30%的田土,可用井岗霉素150毫升或井岗霉素高浓度粉剂1包(25克装),对水75～100公斤喷施茎秆基部防治。小麦锈病分叶锈、条锈、秆锈三种,以叶锈病为害最重,可造成小麦严重减产,甚而颗粒无收。此病从2月中下旬开始 In recent years, the province of wheat sheath blight increased year by year. Rust disease recovers, the incidence of powdery mildew expands, and the scab occurs in some places. Wheat aphids occur in a large area. They have become serious obstacles to the yield increase of wheat. All areas should pay attention to it and take measures to strengthen prevention and control. The control of sheath blight should be pre-sowing, continuous cropping, weeds and more, high nitrogen fertilizer, susceptible varieties of wheat as the focus of prevention and control. At the late tillering stage, the rate of diseased plants reaches 5%, and the rate of diseased plants at jointing stage reaches 20-30%. One can use 150 ml of Jinggangmycin or 1 bag of high-concentration Jinggangmycin (25 g) Kilo spray stems base control. Leaf rust rust, stripe rust, stalk rust three, to leaf rust most seriously affected, can cause serious wheat yield, and even crop failure. The disease began in late February
