Getting to grips with blight
Getting to grips with blight
Just when and how often
can you use different
potato blight fungicides
this season? We take a
closer look at the label
advice for some of the key
products on the market
WITH severe blight pressure now bearing down upon crops, potato growers are pushing ahead with disease control programmes. But difficult spraying conditions and increasingly strict monitoring by processors and retailers mean product choice needs careful consideration.
Here we have brought together the key label advice for the main potato blight fungicides to help you achieve the best blight control possible, while still complying with label advice.
Key to ensuring a close compliance with label advice is checking the precise MAFF number of the product being used, since label advice can vary depending upon formulation and date of manufacture.
While every effort has been taken to source the most up-to-date data, direct from the manufacturers, users should always check label details before applying a pesticide. *
