进行6%聚醛·甲萘威颗粒剂防治甘蓝蜗牛的药效对比试验,结果表明:6%聚醛·甲萘威颗粒剂对甘蓝蜗牛具有良好的防治效果。在甘蓝蜗牛发生初期每667 m2施用6%聚醛·甲萘威颗粒剂750 g、600 g 1次,药后5 d的防效为94.96%和91.28%,高于6%聚醛·甲萘威颗粒剂450 g及对照药剂6%四聚乙醛颗粒剂。6%聚醛·甲萘威颗粒剂750 g药后10 d的防效仍可高达95.04%。生产上建议在甘蓝蜗牛发生初期,每667 m2使用6%聚醛·甲萘威颗粒剂750 g进行防治。
A comparative study on the efficacy of 6% polyaldehyde and carbenicillin in the control of cabbage snail was conducted. The results showed that 6% polyaldehyde and carbaryl had good control effects on cabbage snail. In the early stage of the cabbage snail, 6% polyaldehyde carbendazim granules were applied at a dosage of 750 g and 600 g for every 667 m2, and the control effect was 94.96% and 91.28% on the 5th day after the treatment, which was higher than that of 6% Wei Granule 450 g and the control agent 6% four acetaldehyde granules. The control efficacy of 6% polyaldehyde and carbenicillin granules at 750 g after 10 d could still reach as high as 95.04%. Production recommendations In the early stages of cabbage snail, use 6% polyaldehyde carbendazim 750 g per 667 m2 for control.
