The maximum application rate 210g metaldehyde a.s./ha. For the additional protection of water, suppliers/BASIS advisers may recommend rates reduced to 160g metaldehyde a.s./ha or less (from any combination of metaldehyde products).
To stay within the maxiumum MSG rates it is important to vary the rate according to % of the chosen metaldehyde product. The tables below help to make the maximum dose rates more meaningful to operators using different % metaldehyde products.
Please note a 6 metre no spread zone must be employed adjacent to watercourses.
Using a typical 5kg/ha spreading rate, the dose of metaldehyde applied will vary according to a product's %:
Using the tables below, or calculator on the home page, operators can work out the maximum kg/ha of products that can be applied during the restriction peroid and within the calendar year.
1st August - 31st December
