Slug Control
Slugs are a major pest of agricultural and horticultural crops which left unchecked can cause significant damage. A number of cultural control methods are employed but when conditions are difficult and these measures are not sufficient, chemical control options are a last resort. The most common crop protection product used in arable crops in the UK is metaldehyde-based slug pellets. Metaldehyde is often detected in raw water above the drinking water standard, with peaks following rainfall. While levels detected pose no danger to health or the environment, the UK’s environment agencies and Defra are responsible for the implementation of the Water Framework Directive. Unless action is taken, regulatory restrictions, or even withdrawal, may be enforced. Best practice advice on the application of Metaldehyde-based slug pellets, including guidelines on reduced rates and timings, has been produced by the Metaldehyde Stewardship Group (MSG) and is available.
