[目的]为了开发防控马铃薯晚疫病的新药剂,实现化学农药的减量增效,以植物提取物香芹酚与化学农药霜霉威复配采用转相法制备水乳剂。[方法]采用菌丝生长速率法分别测定香芹酚、霜霉威以及不同配比对马铃薯晚疫病菌的生物活性,通过Wadley方法评价不同配比的增效作用,筛选最佳质量比。筛选了关键的溶剂和乳化剂组合,确定了最佳配方,测定了该制剂的质量指标,并进行了盆栽试验。[结果]香芹酚、霜霉威对马铃薯晚疫病菌的EC50值分别为16.1552、0.8353 mg/L,香芹酚与霜霉威在质量比为30:1时,SR最大为1.393 05,判断为相加作用,其EC50值为7.2864 mg/L。10%香芹酚·霜霉威水乳剂的最佳配方:香芹酚与霜霉威...

[Aims]This study aims to develop new agents for the prevention and control of potato late blight and to reduce the amount and increase the efficacy, this paper prepared water emulsion by phase transfer method with plant extract carvacrol and chemical pesticide propamocarb.[Methods]The mycelial growth rate method was used to determine the virulence of carvacrol, propamocarb and different ratios to Phytophthora infestans, and the Wadley method was used to evaluate the synergistic effects of different ratios to screen out the best quality ratio.Th...
