Tom Ashfield and a multidisciplinary team have been looking at using multispectral imaging to detect slugs in fields. At the moment only really 2 tools available for slug control in agriculture: slug pellets (ferric) and nematodes, which are too expensive to make economic sense in arable crops. By getting more precise data about here the slugs are, you can target the areas with high slug density. As a result, the amount of product (molluscicide/nematodes) can be reduced, with economic and environmental benefits.
