Dutch tests on a new strain of potato blight similar to that discovered for the first time in the UK last year have shown some isolates have reduced sensitivity to the common active fluazinam used to control the disease.
The results from the Dutch trials have, however, prompted experts to remind growers of the importance of following best practice guidelines when using fluazinam this season. The fear is that fluazinam insensitive phyptophthora infestans could become established in the UK.
