Approvals were withdrawn last September following the introduction of new EU residue levels that could have been breached on these crops despite growers following good agricultural practice.
The new approvals include, for the first time, a limit of 700g on the maximum amount of metaldehyde that can be applied per hectare per year. There is no restriction on the number of pellet applications if the total amount of metaldehyde is not exceeded, said De Sangosse managing director David Cameron.
Harvest intervals of seven days on cauliflower and 21 days on potatoes have also been introduced.
The NFU has warned that growers of cauliflower or potatoes could be fined for using metaldehyde products without the appropriate label approval.
- Vegetable growers can visit the new area for pellets and pelleting at the arable event Cereals on 10-11 June in Cambridgeshire.
