Metaldehyde, the active ingredient in Deadline, set the standard for effective slug and snail control in field, fruit and vegetable crops. Deadline Bullets (4% metaldehyde), dye-free to prevent staining on leaves and other crop surfaces, are choice for application in berries and vegetable crops. Deadline Bullets are rain fast, and can withstand as much as 6 inches of rain over a two week period, unlike competitive baits which dissolve and fall apart in as little as 1 inch of rain.
