Blackberry Botrytis Resistance Profile

Botrytis (gray mold) is a common sight in strawberry fields, especially if it has been a rainy season. Although less common in blackberry fields, it can occur.

Guido Schnabel, Clemson Univ. is offering to test blackberry/raspberry samples to determine if you have resistance to  botrytis (gray mold) fungicides at your farm. He has done this for strawberry growers for a number of years and some blackberry growers have also used this service. It is a great way to determine if what you are spraying is effective in controlling gray mold.

See the link below for downloadable instructions. They suggest you use the swabs instead of fruit, because they are easier to ship. Note also that each farm will get 2 free samples analyzed, if you would like more than that, there will be a $110 charge.

Please share these with folks that may be interested.
