Powering up slug control…get ready for battle

Slug pellets should only be applied once populations have reached threshold.
The best time to assess slug populations is when the weather is mild and soil is damp, with the most effective method being to use refuge traps: each trap or shelter should consist of a tile, hardboard sheet or 25-30cm plant pot saucer which will provide a refuge underneath which slugs can gather. Each trap should be baited with a suitable food source (two heaped teaspoonfuls of chicken layer’s mash is recommended), but it is important not to use slug pellets for this purpose.
The traps allow free movement of slugs which are more likely to visit in mild and moist night-time conditions and stay until the following morning when they can be counted.
In each field, nine traps (13 in fields >20ha) should be set out in a W pattern, with the traps concentrated in areas known to suffer damage. The following thresholds indicate a risk when soil and weather conditions favour slug activity:
When, and only when these thresholds have been reached should a suitable molluscicide, such as Gusto® IRON be applied.
