Can anyone answer this thread's question?

"Is Rose killing Rose rosette being spread by infected commercial mulch?"

We know how it spreads. It's not from mulch. Not saying it couldn't happen, but I doubt the mites would survive being chopped up and then composted.

RE: rose rosette virus - something to think about

I doubt it too with commercial mulch and their composted temperatures. I am concerned that another vector for this disease might be aphids as they mimic the mites in terms of their sucking parts of the sap.
Currently from what I understand, there is not enough research money or someone setting up a scientific study to determine if aphids are another vector of this disease.

RE: rose rosette virus - something to think about

I bought a bunch of bags of mulch this weekend. I forgot to put out two of them. So last night I opened them and put them down. The mulch was so HOT!. I hope that killed all the weeds I put it over.

Those bags sit out in the sun at Home Depot or whatever. I'm not sure the mites could survive that. But still, don't put a RRD bush in the landfill or compost!
