作者通过对11种杀菌剂室内外研究,从中筛选出丙环唑(Propiconazole)防治小麦全蚀病(Gaeumannomyces graminis var. tritici)效果显著;不同剂量试验结果,用25％丙环唑乳油按种重0.1％—0.2％拌种比较经济有效;不同施药方法中,丙环唑按种重0.1％—0.2％拌种或0.1％拌闷种防病效果优于浸种、茎叶喷雾;通过持效期、作用方式和药害试验证明,丙环唑用量低,持效期较长,以保护作用为主,也有一定的治疗作用,在上述用量范围内对小麦安全。大田防治示范结果,用25％丙环唑按种重0.2％拌种,控制白穗效果达90.70％以上,每ha平均增产1194.45kg,保产效果达32.35％,为小麦全蚀病综合防治提供了一项有效措施。
Through the study of 11 fungicides indoor and outdoor, the effect of propiconazole against Gaeumannomyces graminis var. Tritici was obvious. The results of different doses of propiconazole were evaluated by 25% propiconazole EC 0.1% -0.2% seed dressing is more economical and effective; propiconazole is better than soaking seeds and stems and leaves sprayed by 0.1% -0.2% seed dressing or 0.1% Period, the mode of action and the phytotoxicity test showed that propiconazole low dosage, longer duration, with the main protective effect, but also a certain therapeutic effect, within the above range of wheat safety. Field control demonstration results, with 25% propiconazole according to the seed weight 0.2% seed dressing control effect of white spike up to 90.70%, an average yield of 1194.45kg per ha, the yield of 32.35%, for the comprehensive prevention and treatment of wheat ecliposis provide An effective measure.
