通过对11种杀菌剂室内外研究,从中筛选出敌力脱(TILT)防治小麦根病效果显著;不同剂量拌种试验表明,用25％敌力脱乳油按种重的0.1％～0.2％拌种比较适宜,控制白穗效果好,保产效果显著;敌力脱拌种与茎叶喷雾试验证明,拌种效果优于茎叶喷雾,方法简便、省工、省时;并且在上述用量范围内对小麦安全。大田防治示范结果,用25％敌力脱乳油按种重的0.2％拌种。控制白穗效果达90.7％以上,亩平均增产79.63kg,保产效果达32.35％,经济效益显著,为小麦根病综合防治提供了一项有效措施。
The effects of TILT on wheat root blight were screened out through the study of 11 fungicides indoors and outdoors. The experiments of seed dressing with different dosages showed that with 25% It is more suitable to control the white spike effect and has a significant effect on yield protection. The stripping and seed spraying experiments show that the seed dressing effect is better than that of stem and leaf spraying, the method is simple, labor saving and time saving; and in the above dosage range Within the wheat safety. Demonstration results of field control, with 25% of the enemy de-EC oil seeds by 0.2% seed dressing. Control effect of white spike up to 90.7%, the average yield of 79.63kg acres, yield of 32.35%, with significant economic benefits, provides an effective measure for the comprehensive prevention and treatment of wheat root disease.
