Recent research by EuroBlight has highlighted a new blight genotype that has spread rapidly across mainland Europe, and was reportedly found in some British crops late last year.
Growers need to remain aware of the huge risk resistance poses to the sector, and should have a robust Integrated Crop Management (ICM) strategy in place to ensure sustainable protection of their crops.
What can you do?
Samples taken in the Netherlands and Germany have demonstrated that this new strain, EU_37_A2, has a reduced sensitivity to Fluazinam, resulting in unexpectedly high tuber blight infection risk.
Making use of alternative chemistry and applying a blight fungicide with two or more Modes Of Action (MOA) will help in the battle towards protecting against particularly virulent strains.
Using a product like Valbon, which includes two different actives with two different MOA that have not been shown to be sensitive to the new strains, can help with resistance management.
This is a serious issue, but by drawing on a well-prepared ICM strategy and the latest research to ensure your crop management is as proactive as it can be, it’s possible to stay one step.
