经1991～1995年室内、田间试验,筛选出丙环唑(Propiconazole)、三唑酮(Triadimefon)等三唑类杀菌剂为防治小麦根病的有效药剂。这类内吸性的杀菌剂不仅对小麦根病的主要致病菌全蚀病菌(Gaeumannomyces graminis var. tritici)和麦根腐离蠕孢菌(Bipolaris sorokiniana)毒力强,且对小麦生长有良好的调节作用,可降低小麦苗期株高,促进根系发育,提高幼苗根冠比,增强根系活力,增加单位重量叶片叶绿素含量。在各试验处理中,以25％丙环唑EC拌种加苗期喷洒白穗防效高达98.4％。改变药剂剂型和处理方法,延长药效,且提高防效,湿拌闷种的防病增产效果优于干拌。
From 1991 to 1995, indoor and field trials were conducted to screen out triazole fungicides such as Propiconazole and Triadimefon as effective agents for controlling wheat root diseases. Such systemic fungicides not only have high virulence to Gaeumannomyces graminis var. Tritici and Bipolaris sorokiniana, but also have good growth on wheat Can reduce the height of wheat seedling, promote root development, increase seedling root to shoot ratio, increase root activity and increase chlorophyll content per unit weight of leaves. In each treatment, the control effect of spraying 25% propiconazole EC with white spike seedlings was as high as 98.4%. Change the dosage forms and treatment methods to extend the efficacy, and improve anti-disease effect, wet mixed bored species of disease prevention and increase yield better than dry mix.
