恩施州不同药剂防治马铃薯病毒病田间药效试验

Field efficacy trial of different agents against potato virus disease in Enshi prefecture

筛选出比较理想的盐酸·吗啉胍、氨基寡糖素、太抗几丁、宁南霉素、病毒灵5种马铃薯(Solanum tuberosum L.)病毒病防治药剂,以恩施州当地农用自留种米拉为研究对象,结合相关农艺措施,5种药剂对病毒病的防治效果。结果表明,氨基寡糖素和核酸吗啉胍对马铃薯病毒病防效较好,相对防效分别为55.06%和44.95%,其增产效果明显,分别较CK增产22.71%和21.38%。

Five ideal agents for the prevention and control of viral diseases were screened out,including morinidine hydrochloride,amino-oligosaccharide,antichitin,ningnanmycin,viralin.Taking Enshi prefecture local agricultural use of self-retention species Mi⁃ra as the research subject,combining relevant agronomic measures,the prevention and control effects of the above five agents were studied for viral diseases.The results showed that amino-oligosaccharide and mononidine had better control effect on potato virus dis⁃ease,and the relative control effect was 55.06%and 44.95%,respectively,and the yield increase was 22.71%and 21.38%,respec⁃tively,compared with CK.
