摘　　要：为了明确四聚乙醛不同浓度及加工含量对蔬菜蜗牛的防效,本研究利用80%四聚乙醛WP,60%、10%、15%四聚乙醛GR等药剂进行防治甘蓝蜗牛对比试验。试验结果表明,6%、10%和15%四聚乙醛GR对甘蓝蜗牛有较好的防效,显著优于80%四聚乙醛WP和5%甲萘威GR。6%、10%和15%四聚乙醛的施用浓度为360、450、540 g/hm^(2)时,防效呈现递增趋势,但浓度为450、540 g/hm^(2),防效间无显著差异,校正防效均大于88%。四聚乙醛高含量颗粒剂速效性好,相同使用剂量条件下,四聚乙醛颗粒剂撒施效果显著高于四聚乙醛可湿性粉剂喷雾防效。In order to clarify the control of different formulations and contents of metaldehyde on cabbage snails,a comparative experiment was conducted in the field.The results showed that 6%,10%,15%metaldehyde GR had good and fast effect for controlling cabbage snails,and significantly better than the treatment effect of 80%metaldehyde WP and 5%carbaryl GR.When the dose of metaldehyde GR were 360,450,540 g/hm^(2),the control effect showed an increasing trend,but there was no significant difference at dose of 450,540 g/hm^(2).The control effect on cabbage snails was close to or more than 88%.High content metaldehyde GR had good instant effect.Under the same dosage,the effect of metaldehyde GR was significantly higher than that of metaldehyde WP.
