苯醚菌酯·霜霉威复配新型杀菌剂,经室内生物活性测定结果表明:苯醚菌酯·霜霉威以质量比1:20混配时,该组合物对黄瓜霜霉病具有很高的杀菌活性。田间试验初步结果表明组合物在1000～250mg/L剂量下,对黄瓜霜霉病的防效在93.0%～73.6%之间。苯醚菌酯·霜霉威的作用机制虽然不同,但2种有效成分组合在一起,对黄瓜霜霉病具有明显的增效作用,并能有效延缓抗性的产生。
Phenylcarbamate · propamocarb complex with a new fungicide, the indoor bioassay results show that: phenylsuite ester · propamocarb at a mass ratio of 1:20 when the combination of the composition of cucumber downy mildew is very High bactericidal activity. The preliminary results of field experiments showed that the control effect of the composition on cucumber downy mildew was between 93.0% and 73.6% at the dosage of 1000-250mg / L. Although the mechanism of action of phenylfenorubicarb and propamocarb is different, the combination of the two active ingredients has obvious synergistic effect on cucumber downy mildew and can effectively delay the generation of resistance.
