Tired of slugs eating fruit and veggies in your garden? Big holes in your strawberries? Johan Watz and Daniel Nyqvist (Politecnico di Torino, Italy) have a new paper out on the performance of copper and waterglass (sodium silicate) barriers against movements of Spanish slugs (Arion vulgaris).

Copper foil barriers delayed, but did not prevent slug passage. Waterglass, on the other hand, prevented passage completely and reduced crop damage in a semi-field validation. You can read the full paper here: https://www.sciencedirect.com/science/article/pii/S0261219420304580
