You refer to labeled fungicides for treating cytospora fungus on the above.What are these and are they commercially available? Names and chemical composition would be helpful!

Hi, Thanks for your question. Unfortunately our system does not show us what web page you were looking at when you submitted your question. Can you tell me what page or publication you found the information on cytospora fungus on? That information will help me assign your question to he correct expert. Thanks!
The attached publication has information about fungicide spray options, but take note that fungicides alone will probably not adequately control this disease. Make sure that you are following proper watering, fertilizing, and pruning strategies, as well as practicing good sanitation around the trees.
