摘　　要：为了减少马铃薯晚疫病防治中化学农药喷施剂量和次数,降低对马铃薯品质和环境的潜在威胁,本研究选择4种生物药剂在两个地区进行马铃薯晚疫病田间试验。结果表明,1000亿孢子·g^(-1)枯草芽孢杆菌可湿性粉剂、0.3%丁子香酚可溶液剂、5%香芹酚水剂、0.5%苦参碱水剂对马铃薯安全,且对马铃薯晚疫病均有防治效果,防效为35.86%~71.41%,商品率比对照增加0.9~5.1百分点;增产幅度2.6%~7.6%;增加产值34.3~2656.5元·hm^(-2),增效0.1%~6.3%。In order to reduce the dosage and frequency of chemical pesticide spraying in the prevention and control of potato late blight,and reduce the potential threat to potato quality and environment,four biological agents were selected to conduct field trials of potato late blight in two regions.In this experiment,four biological fungicides were selected tofield trials of potato late blight in two areas.The results showed that 100 billion spores·g^(-1) of Bacillus subtilis WP,eugenol 0.3%SL,carvacrol 5%AS and matrine 0.5%AS were safety to potato and had effective control to potato late blight.The control effect of potao late blight were 35.86%-71.41%,and the commodity rate increased by 0.9-5.1 percentage points,the yield increased by 2.6%-7.6%,the output value increasedby 34.3-2656.5 yuan·ha^(-1),and the effect increased by 0.1%-6.3%.
