摘　　要：本研究旨在评估几种化学防治药剂对山东临沂市郯城县马头镇马铃薯晚疫病的田间防治效果。通过选取687.5 g/L氟菌·霜霉威悬浮剂、72%甲霜灵锰锌、42.8%氟菌·肟菌酯悬浮剂和100亿个/g枯草芽孢杆菌生物制剂,设对照与处理组,监测病情指数、防治效果和产量。结果表明,687.5 g/L氟菌·霜霉威悬浮剂控制病情效果显著,2020年3次用药后病情指数分别为3.21、5.13和6.02,防治效果超80%,最高达85.14%,增产27.9%;2021年3次用药病情指数分别2.95、4.75和5.45,防治效果超84%,增产26.0%。42.8%氟菌·肟菌酯悬浮剂防治效果略逊但优于其他药剂。强调了根据地区特定条件选择防治药物的重要性,并推荐687.5 g/L氟菌·霜霉威悬浮剂作为该区域马铃薯晚疫病的优选防治药剂,研究结果为农民提供了科学的防治指南。To evaluate the field control effects of several chemical control agents on potato late blight in Matou Town of Tancheng County,Linyi City,Shandong Province,687.5 g/L fluopyram-penoxifen wettable powder,72%mancozeb-manganese zinc,42.8%fluopyram-iprovalent wettable powder,and 10 billion/g Bacillus subtilis biological preparation were selected,and a control group and treatment groups were set up,and the incidence index,control effect,and yield were monitored.The results showed that the 687.5 g/L fluopyrampenoxifen wettable powder had a significant control effect on the disease.In 2020,the incidence index was 3.21,5.13,and 6.02 after three applications of the treatment,with an average control effect of over 80%and a maximum of 85.14%,and an increase in yield of 27.9%.In 2021,the incidence index was 2.95,4.75,and 5.45 after three applications of the treatment,with an average control effect of over 84%and an increase in yield of 26.0%.The 42.8%fluopyram-iprovalent wettable powder had a slightly lower control effect but was better than other pesticides.The importance of selecting control agents based on regional specific conditions was emphasized,and fluopyram-penoxifen wettable powder was recommended as the preferred control agent for late blight of potato in the study area.The research results provide scientific control guidelines for farmers.
