Hello! This is my first post as a new member of this forum...we are having a problem with volutella blight on our pachysandra flats and gallons. I have two questions:
1. Do we destroy our entire crop or can it be saved? And if it can be saved, how?
2. Is there a way to take cuttings from the pachysandra flats on areas that don't look affected since they are technically rooted seperately? Or is this a waste of time?
These are in an inside greenhouse and unfortunately were too closely spaced to begin with so we know air circulation/humidity were a factor. We are just west of St Louis, MO
Any help would be greatly appreciated!
I would say you first line of defense would be to space them out and reduce any stress on them. Then follow up with a full coverage spray of Chlorothalonil.
Thank you Eric for responding! Would you throw away the diseased ones away or cut them back to flush back out? Would you take cuttings from a flat that had some with the symptoms and some not? Would you recommend the same treatment for Phytophthora? We have been told in the past the problem was Phytophthora but haven't tested this year and the symptoms are so similar (Phy and Blight)
I appreciate you taking the time to answer..
You could clip them back and apply the spray of Chlorothalonil. I think Pachysandra always has blight to some degree. It's just a matter of keeping it under control with environmental and culture conditions. The chemical sprays will help bridge the gap.
Thank you Eric!!
