Free Botrytis Fungicide Resistance Testing

Written by

Phil Brannen

If you see Botrytis in your grapes, it is always a good idea to test for fungicide resistance in your pathogen population. While the funds last, you can receive free testing. The results can provide you with information on which fungicide classes are working and which are not. This will allow you to switch fungicides to more active compounds/classes as the season progresses. See the link below for details. I would encourage you to all sign up for this Southern Region Small Fruit Consortium Newsletter. Not all the articles are on grapes, but you will find good information on grapes and other small fruits.
