Arionid slugs can be serious pests on horticultural and agricultural crops. Using slug movement barriers is a potentially effective method to control slug damage. We evaluated the performance of waterglass (sodium silicate) and copper foil as barriers against Arion vulgaris movement both in a controlled experiment and in a semi-field validation under natural conditions. We used strawberry fruits as baits behind the barriers and monitored slug movement and damage to the strawberries. In the controlled experiment, copper foil barriers delayed but did not prevent passage, whereas waterglass barriers completely hindered slugs from passing. Barrier width (3, 4 or 6 cm) did not affect the passability of the barriers. In the semi-field validation, there was no difference in slug damage events between pots with and without copper foil barriers. Waterglass barriers applied to the pots reduced slug damage events by 50% compared with pots without a barrier. Using waterglass to hinder slug movement may prove to be a cost-effective method to control slug damage in horticulture without any adverse side effects on non-targeted organisms.

芳香族可能是园艺和农作物上的严重害虫。使用弹头移动障碍物是控制弹头损坏的潜在有效方法。我们评估了水玻璃（硅酸钠）和铜箔作为抗Arion的屏障的性能在自然条件下在受控实验和半场验证中进行运动。我们使用草莓果实作为障碍物的诱饵，并监测弹头运动和草莓损坏。在对照实验中，铜箔屏障延迟但不能阻止通过，而水玻璃屏障则完全阻止了弹丸的通过。障碍物的宽度（3、4或6厘米）不影响障碍物的通过性。在半场验证中，有铜箔障碍物和无铜箔障碍物的锅之间的弹头损坏事件没有差异。与没有障碍物的花盆相比，应用于花盆的水玻璃障碍物将的损坏事件减少了50％。
