烯酰吗啉与喹啉铜混剂防治黄瓜霜霉病和细菌性角斑病

The Mixture of Dimethomorph and Copper Quinolate against Cucumber Downy Mildew and Cucumber Angular Leaf Spot

[目的]明确烯酰吗啉与喹啉铜混剂对黄瓜霜霉病和细菌性角斑病的综合防治作用。[结果]室内联合毒力试验结果表明,烯酰吗啉与喹啉铜混剂在5∶1~1∶5配比范围内,对黄瓜霜霉病表现出显明相加作用;田间试验,当黄瓜霜霉病和黄瓜细菌性角斑病混合发生时,用作保护剂,相同质量浓度下,烯酰吗啉与喹啉铜混剂的综合防治效果显著高于单剂。[结论]烯酰吗啉与喹啉铜桶混在黄瓜霜霉病和黄瓜细菌性角斑病混合发生的田块应用,具有很好的综合防治效果。该技术值得推广和应用。

[Aims] This study aims to confirm the integrated control of the mixture dimethomorph and copper quinolate on cucumber downy mildew and cucumber angular leaf spot. [Results] The results indicated that the mixtures of dimethomorph and copper quinolate afforded an addition joint action on cucumber downy mildew in the range of 5：1 to 1：5 in synergistic Action test. In field, the integrated control of the mixtures of dimethomorph and copper quinolate was significantly higher than the single at the same concentration as the protective fungicide when cucumber downy mildew and cucumber angular leaf spot occur mixedly. [Conclusions] Tank-mix of dimethomorph and copper quinolate achieved integrated excellent control on cucumber downy mildew and cucumber angular leaf spot which occur mixedly in field. This technology is worth to be promoted and to be applied in market.
