Downy Mildew treatment
So you conducted a lab diagnosis and culturing and have positively confirmed Downy Mildew? It has been so cold that I have not heard of any Downy disease anywhere in the midwest or northeast yet.
I would suggest you contact our hop disease specialist, here is her contact information, If you have not had a lab diagnose the disease in the lab yet, Dr. Ivey will be able to help you with that lab culturing in her lab at Wooster.
