Good fungicide mixing strategies will be the most effective way of managing blight this season, says expert.
EFFECTIVE fungicide mixing strategies are the key to managing the increasing incidence of blight resistance in potato crops according to Syngenta Technical Manager, Andy Cunningham.
Andy says growers can still retain the benefits of utilising the most potent chemistry to protect crops.
Speaking at the Potato Science Live events this spring, he highlighted how the mandipropamid mixing strategy enabled growers and agronomists in Denmark to dramatically reduce the outbreaks of CAA-compromised blight strain EU 43 from more than 70% of recorded cases in 2022, to less than 20% of outbreaks last season.
As a result, the recommendations for the use of the Syngenta product Revus in Denmark have increased by more than 60% for this season, from two applications per crop to five, with a range of fungicide mixes. “UK growers are in a far more fortunate position, given that the EU 43 strain has never been sampled in blight monitoring programmes, and they have many more options available for mix partners.”
