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 %:
| Product % metaldehyde |
g of metaldehyde |
| 4% | 200g |
| 3% | 150g |
| 1.5% | 75g |
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.

Maximum kg/ha of product per calendar year* |
| 5% | 4% | 3% | 1.5% | |
| 210g | 4 kg/ha | 5 kg/ha | 7 kg/ha | 14 kg/ha |
| 160g | 3 kg/ha | 4 kg/ha | 5 kg/ha | 10 kg/ha |
| 5% | 4% | 3% | 1.5% |
| 14kg/ha | 17kg/ha | 23kg/ha | 46kg/ha |
* To stay within 700g metaldehyde maximum per year
