| 摘 要： | 本试验在温室内用有效成分浓度25、50和100ppm的羟锈宁和粉锈中浸种,对种子的发芽势和发芽率没有明显影响,浸种对开始出土的幼苗有一定的抑制作用,但后期长势无明显差别,而叶片稍浓绿,似有一定的壮苗作用,浸种后防效达64.2—99.8%.100ppm羟锈宁的保护作用在3天内可达92.5%,到第7天下降至72.2%.羟锈宁的治疗作用比较明显,在叶锈菌侵入寄生后的6天内防效显著,100ppm羟锈宁的治疗效果为100%,有效成份浓度100ppm的羟锈宁和粉锈宁,对小麦没有药害.

| Abstract: | Wheat seeds were soaked with Baytan and Bayleton 25ppm, 50ppm and 100ppm a.i. respectively to control leaf rust in green house. There was no effect on the germination of seeds and the effectiveness of control was 64.2 -99.8%.The protective effect of Baytan was 92.5% within 3 days after treatment, but decreased to 72.2% 7 days later. The curative effect of Baytan obviously evident within 6 days after inoculation and Baytan 100ppm gave 100% control. Spraying Baytan and Bayleton 100ppm had no harmful effect to wheat seedling. |
