Research helps growers fight peach brown rot

 

Guido Schnabel: Peaches are threatened by a disease called brown rot of peach. It is a disease that develops in the field but later it also causes a post-harvest rot of the peach. In any particular year, the brown rot disease can cause about five to ten percent loss but in a really bad year, it can climb up to about twenty to thirty percent. The resistance monitoring program that we developed for strawberries is also suitable for detecting fungicide resistance in the brown rot fungus. We are able to tell the growers which fungicides are working the best. He is then capable of using better products and avoiding using products that do not work. That in a year with a lot of moisture and cool temperatures would save peach growers a lot of money.
