近年来,小麦纹枯病逐年加重,锈病重新抬头,白粉病发病面积扩大,赤霉病在不少地方流行,麦蚜发生量加大。这“四病一虫”已成为小麦增产的严重障碍。因此,要夺取小麦丰收,就要防治好“四病一虫”。 纹枯病 掌握分蘖末期病株率达5％,拔节期病株率达20％～30％时,667平方米用5％井岗霉素150毫升,或用井岗霉素高浓度粉剂25克对水70～100千克喷施茎 In recent years, wheat sheath blight increased year by year, rust recovers, the incidence of powdery mildew expanded, scab prevalence in many places, the occurrence of wheat aphid increased. This “four diseases and one worm” has become a serious obstacle to increasing wheat yield. Therefore, to seize the bumper harvest, we must prevent and treat “four diseases and one worm.” Rhizoctonia solani grasps the rate of diseased plants at the end of tillering to 5%, the rate of diseased plants at jointing stage reaches 20% ~ 30%, 66% of 150ml of 5% Jinggangmycin 667 square meters or 25ml of Jinggangmycin high concentration powder Stems are sprayed on 70-100 kg of water
