阅读说明：本技术 两种蒽醌类化合物在防治根结线虫病方面的应用 (Application of two anthraquinone compounds in preventing and treating root knot nematode disease ) 是由 黄衍章 李彩斌 李章海 毛振坤 杨云飞 丁涛 于 2021-10-12 设计创作，主要内容包括：本发明公开了两种蒽醌类化合物在防治根结线虫病方面的应用,涉及生物农药应用领域。本发明所述两种蒽醌类化合物源于掌叶大黄根茎提取物,分别为大黄素(1,3,8-三羟基-6-甲基蒽醌)和芦荟大黄素(1,8-二羟基-3-羟甲基蒽醌),其对南方根结线虫等有较高的致死率,可用于开发源于中药草的杀线剂；可用于制备防治根结线虫病的水乳剂、可湿性粉剂、可溶性粉剂、可溶粒剂、水分散粒剂、悬浮剂、油悬浮剂和片剂。本发明难以使线虫产生抗药性,也不存在药剂残留问题,符合有害生物绿色防控技术的基本要求；本发明用于防治植物根结线虫病,有利于保护农田生态环境和生物多样性,具有良好的生态效益。(The invention discloses application of two anthraquinone compounds in preventing and treating root knot nematode diseases, and relates to the field of application of biopesticides. The two anthraquinone compounds are derived from Rheum palmatum rhizome extracts, are emodin (1,3, 8-trihydroxy-6-methylanthraquinone) and aloe-emodin (1, 8-dihydroxy-3-hydroxymethyl anthraquinone), have high lethality to Meloidogyne incognita and the like, and can be used for developing a nematicide derived from traditional Chinese medicinal herbs; can be used for preparing emulsion in water, wettable powder, soluble granules, water dispersible granules, suspending agents, oil suspending agents and tablets for preventing and treating root knot nematode diseases. The invention is difficult to cause the nematode to generate drug resistance, has no problem of drug residue, and meets the basic requirements of the green prevention and control technology of pests; the invention is used for preventing and controlling plant root knot nematode disease, is beneficial to protecting the ecological environment and biological diversity of farmlands, and has good ecological benefit.)
