The marsh slug, (Müller), is a generalist pest of agricultural crops. Slugs are mainly managed with synthetic pesticides that can also have high toxicity toward vertebrates and nontarget arthropods. Besides, they are not labeled for use in organic crop systems. Bordeaux mixture (BM) is an alternative product often used in organic crops for controlling plant diseases. The molluscicidal activity of BM has been reported; however, to our knowledge, no study has determined its efficacy to control . This study aimed to determine the lethal (concentration- and time-mortality curves, and foliar persistence) and antifeedant (reduction in leaf consumption) effects of BM-treated cabbage leaves on . The LC of BM was 28.15%, and the LT was 8.83 h. The BM LC reduced leaf consumption by 3.31-fold. Furthermore, high control effectiveness (mortality > 90%) was attained until the 7 day after spraying. These findings reveal that BM reduces damage by killing in a fast faction and by reducing foliar consumption. Therefore, BM can be an alternative to management in both conventional and organic systems.
黄蛞蝓（Müller）是一种农业作物的通用害虫。蛞蝓主要通过合成农药来管理，但这些农药对脊椎动物和非目标节肢动物也有很高的毒性。此外，它们在有机作物系统中没有被标记为可用。波尔多混合物（BM）是一种常用于有机作物的替代产品，用于控制植物病害。BM 具有杀软体动物活性，已有报道；然而，据我们所知，尚无研究确定其防治 的功效。本研究旨在确定 BM 处理的甘蓝叶片对 的致死（浓度和时间死亡率曲线，以及叶面持久性）和拒食（减少叶片消耗）作用。BM 的 LC 为 28.15%，LT 为 8.83 小时。BM 的 LC 使 叶片消耗减少了 3.31 倍。此外，在喷洒后的 7 天内，高控制效果（死亡率>90%）得以维持。这些发现表明，BM 通过快速杀死 和减少叶片消耗来减轻 造成的损害。因此，BM 可以替代常规和有机系统中的 管理。
