摘要
本研究针对韭菜的多种病虫害问题,综合考虑作物产量和生产安全等因素,配制了8种植物源药剂,分别在病害发生前、发生后及虫害发生后施用,25%戊唑醇可湿性粉剂、25%吡虫啉可湿性粉剂、50%辛硫磷乳油、2.5%高效氯氟氰菊酯做为对照组。结果表明,发病前施药,各类病害预防效率最高可达98.15%(药剂8号);各类虫害的最大治疗效果为88.11%(药剂8号);综合各类病虫害防治结果,含有中药材数量最多的药剂8号为最佳药剂,药剂4~6号效果相差不大,药剂1~3号防治效果相对较差;与对照相比,所有施用药剂的韭菜产量均高于对照组,说明配制药剂不会对受试韭菜产生较大危害。
This study focuses on multiple diseases and insect pests of leek,consider factors such as crop yield and production safety,Prepare 8 botanical drugs,they are administered in before and after the occurrence of the disease,and after the occurrence of pests,25% tebuconazole wettable powder and 25% imidacloprid wettable powder and 10% by Metalaxyl+Mancozeb water dispersible granule and 50% phoxim EC and 2.5% cyhalothrin were used as the control group.The results showed that the highest prevention efficiency of all kinds of diseases could reach 98.15%(No.8)by using tebuconazole and imidacloprid before the disease onset According to the results of all kinds of pest control,the best one was No.8,which contained the most Chinese medicinal materials,and the effect of No.4~6 was similar,the control effect of No.1~3 was relatively poor,and the yield of The leek was higher than that of the control,which indicated that the preparation of medicines was not harmful to the tested the leek.
