Greater vigilance required for Alternaria

The Treater Group, chaired by Mark Taplin, focuses on all aspects of the crop management of potatoes with a core objective of improving standards, consulting on key matters, facilitating knowledge transfer and developing guidelines for best practice.

As we now enter a foliar disease management era without mancozeb it is highly likely that we may see more foliage infection with Alternaria solani. Whilst mancozeb was not a powerful fungicide against this disease, it was a useful preventative treatment, so greater vigilance will be required from now on.

To support growers, the group has created a short information sheet which can be downloaded here.
