Growers are set to lose a key tool used to help control late blight in potato crops. The EU Standing Committee on Plants, Animals, Food and Feed (SCoPAFF) has voted not to renew approval for the active substance mancozeb.

Mancozeb was a widely used multi-site fungicide to control late blight and a number of other diseases in potatoes. The active played an important role in blight resistant-management programmes.
