摘要
田间小区试验结果表明，施药后在雨量较多情况下，６％密达粒剂对烟草蜗牛仍具有良好的防治和保护烟苗的效果。各处理剂量１０．０ｋｇ／ｈａ、８．５ｋｇ／ｈａ和７．０ｋｇ／ｈａ。经统计分析在防治效果上处理间差异不显著，最低剂量７．０ｋｇ／ｈａ，在施药后２天、７天、１６天和２１天的校正防效分别为５２．１２％、６６．６７％、７４．２８％和７７．７４％，其保苗效果分别为７２．７３％、６６．６７％、７２．７３％和６９．４４％。
The results of plot test showed
that 6%Meta pelletized granule could effectively control tobacco snailand protect its seedlings,
although the rainfall was much during the test days.The treatmental dose
was10.0kg/ha,8.5kg/ha,7.0kg/ha respectively with non-significant difference among them.The
correctedcontrolling effect for 7.0kg/ha of minimum dose was 52.12%,66.67%,74.28%and
77.74%respectively,and effect of keeping a full stand of seedling 72.73%,66.67%,72.73%and 69.
44%respectively in 2-day,7-day,16-day and 21-day after applied.
