    Research progress and prospect on chemical control of wheat sharp eyespot in China

    • 摘要: 随着秸秆还田等耕作栽培措施的推广,中国小麦纹枯病发生日趋严重,对小麦的高产、稳产造成了很大威胁。由于缺乏免疫及高抗病性小麦品种,生产中对纹枯病一直采用播期拌种及春季喷雾相结合的化学防治方法。文章总结了当前中国小麦纹枯病的发生现状及主要病原;评述了三唑类药剂对纹枯病菌的毒力及对纹枯病的防治效果,介绍了生产中小麦纹枯病菌对三唑类药剂的抗药性现状及机理,分析了三唑类药剂对小麦的安全性;同时阐述了井冈霉素、甲基立枯磷及其他种类药剂在小麦纹枯病综合防治中的应用;指出小麦纹枯病化学防治的发展方向应是将生防菌剂同化学药剂相结合,实现生物防治与化学防治的协同应用。

       

      Abstract: With the wide application of cultivation techniques, likestraw returning, wheat sharp eyespot, which is caused mainly by Rhizoctonia cerealis, is becoming more and more serious, which is a great threat to the high and stable yield of wheat. Due to the lack of immunity and high resistance varieties, the chemical control of the wheat sharp eyespot has been acchievd by the combination of sowing seed dressing and spring spraying. In this review, the recent research progresses of the current occurrence of wheat sharp eyespot and its control agents were summarized, including the virulence of triazoles fungicides against wheat sharp eyespot, sensitivity monitoring, the resistance status and mechanism of R. cerealis to triazoles fungicides, the safety of triazole fungicides to wheat, and the application of jinggangmycin, tolclofos-methyl and other fungicides in the integrated control of wheat sharp eyespot. The outlook for the development of chemical control methods against wheat sharp eyespot was pointed out: the combination of biocontrol and chemical agents to achieve synergistic prevention and integrated control.
