What is the name or address of the hall at OSU where I can send a sample of my grape vines to find out if they have black rot and how to treat it?
The Gardener’s Answer
Hi, Jason: Black rot is a common fungal disease among grapes. It can over-winter on the vine as well as on any mummified fruit left on the vine or on the ground. This is why good sanitation is essential for grape vines. Ohio State University has a pest and plant diagnostic clinic at the Ohio Department of Agriculture campus in Reynoldsburg. The C. Wayne Ellett clinic is located at 8995 East Main Street in Building 23. This is where you can take a sample of your vine/foliage to be diagnosed. Visit their Web site for directions and more information at http://ppdc.osu.edu/map
. You can reach them by phone at (614) 292-5006. They will be able to give you a definitive diagnosis and potential fungicide program if necessary. http://ohioline.osu.edu/hyg-fact/1000/1423.html is a link to an OSU publication on growing grapes.
