| 摘 要： | 一些蜗牛常栖息在高大植株上活动为害, 为探索其有效防治方法, 分别在玉米田及美国红枫( Acer rubrum L . )园选用5种杀软体动物剂进行喷雾法(在玉米田仅对植株喷雾、在美国红枫园对树体和地面喷雾)和撒粒法的防效对比试验。重复测量方差分析结果表明：26%四聚?杀螺胺悬浮剂1.125 L/hm2、45%三苯基乙酸锡可湿性粉剂1.125 kg/hm2、70%杀螺胺乙醇胺盐可湿性粉剂0.75 kg/hm2、40%四聚乙醛悬浮剂1.125 L/hm2喷雾防治灰巴蜗牛( Bradybaena ravida )的效果均显著高于6%四聚乙醛颗粒剂7.5 kg/hm2地面撒粒的防效。不同药剂不同施用方法的防治效果随用药后时间的增加而降低。用药后第3天, 4种喷雾处理在美国红枫上的防效均在90%左右, 在玉米上的防效在80%左右。当蜗牛在高大的植株上栖息为害时, 可用上述药剂按750 L/hm2的药液用量对植株均匀喷雾, 必要时同时进行地面喷雾防效更佳。

| Abstract: | Some snails often rest or live on tall plants and cause damage. In order to explore an effective method to control the snails, we compared the efficiency of two different application techniques, i.e., spraying vs distributing granule, in controlling Bradybaena ravida (Benson) with 5 formula of molluscicides on corn and American red maple ( Acer rubrum L.). The repeated measures ANOVA indicated that the control efficiencies of spraying 4 molluscicides, i.e., 26% metaldehyde?niclosamide SC 1.125 L / hm2, 45% fentin acetate WP 1.125 kg/hm2, 70% niclosamide clamine WP 0.75 kg/hm2 and 40% metaldehyde SC 1.125 L /hm2, were all higher than that of distributing 6% metaldehyde GR 7.5 kg/hm2. The efficiencies of various molluscicides with different application techniques decreased with elapse of time. The control efficiencies of spraying the 4 molluscicides were 90% on American red maple and 80% on corn at the third day after application. When snails rest or live on tall plants, satisfied control efficiency on snails could be obtained by spraying 750 L/hm2 solution of above mentioned molluscicides, especially in middle and late growing stage of corn, and better control efficiency would be achieved if the spraying was accompanied with distributing granules when necessary. |
