几种药剂防治辣椒疫病田间药效试验

摘要

We studied the efficiencies of different fungicides on controlling pepper phytophthora blight in fields. The results showed that, sprayed three times from bud stage with the interval of 10 days, the following treatments, 500 g/L fenamidone suspension concentrate (SC) 15 g/667 m2, 722 g/L propamocarb hydrochloride aqueous solution 52 mL/667 m2 and 450 g/L fenamidone+propamocarb hydrochloride SC 100-133 g/667 m2, had higher control efficiencies and were safe for pepper.%开展了不同药剂防治辣椒疫病田间药效试验。试验结果表明，从辣椒花蕾期开始连续施药3次，每次间隔10 d，500 g/L咪唑菌酮悬浮剂（SC）15 g/667 m2、722 g/L霜霉威盐酸盐水剂52 mL/667 m2和450 g/L咪唑菌酮·霜霉威盐酸盐SC 100~133 g/667 m2，对辣椒疫病具有良好的防治效果，且对辣椒安全。
