Wilting peony stems- pest or disease?

4 years ago

My peony was thriving this spring but since the start of June, single stems have started to go floppy and wilt. At first, I thought it could be peony wilt but I also noticed a little hole in one of the stems that I cut from the base. Could a pest be causing my problems? Thank you! (first time peony owner)

how about a pic of the rest of the plant ...

and stop cutting off green material.. as long as its green i can process sun light into energy to feed the plant ...

i cant recall if peony stems are hollow.. that doesnt google up for me.... maybe someone else can answer that ..

if you do have borers of some sort.. the ONLY way to manage them would be a systemic product.. as you cant spray inside a stem ....

The second picture shows a neat hole in the side wall of the stem. That looks like a borer exit hole. If you split the stem open is it tunnelled through? Check the other stems. Any more holes?

Looks like stalk borer damage. Page 2 of this .pdf
