摘要
在室内条件下,用枯斑抑制率法测定了宁南霉素、醋酸铜及其5种不同比例的混配对烟草普通花叶病毒的毒力。结果表明,宁南霉素和醋酸铜对烟草普通花叶病的EC70分别为0.9647mg/L和0.4556mg/L,两者以4:1混配具有显著的增效作用,增效系数为1.48。
The synergistic effects of Ningnanmycin,copper aeetate monohydrate and their mixtures-made up by mixingthe two pesticides in different ratios on TMV were tested. The best results could be achieved with 4：1 of Ningnanmycin and copper aeetate monohydrate,the EC70 was 0.964 7 mg/L and 0.455 6 mg/L respectively and the synergistic coefficients was 1.48.
