Pigeonpea sterility has been lumped with the emaras in other papers. This is, apparently, the formal RNA support. Pigeonpea is also transmitted by an eriophyid mite (not the same one as any other of the 'like' viruses, and has been doing horrible things to the pigeon pea crops which are / were major sources of protein for farmers. There is one picture in a recent paper comparing sick and healthy pigeonpea plants. Some contortions of foliage and lack of flowering seem to be symptoms, but a discussion of the symptoms is something I'm still looking for.

Yeah, we were crawling with kudzu bugs the other day. And we don't even have kudzu anywhere near.

What I did was to cut off the diseased growth below the point on the cane that it appeared on. Any new growth from that cane has not shown any more symptoms with the exception of General Cavaignac. It was asymptomatic for a whole year but started showing it again. I cut it off and watered it with more aspirin, and it has been okay. I am suspecting a reinfection rather than a relapse because it is close to the infected Dr. Huey. I have used an aspirin spray. I have used one 325 mg pill per 3 gallons of water, the size of my tank sprayer. I do have to watch it carefully because I have seen foliage burn on some of the plants doing this. There is increased blackspot resistance from this treatment, but again foliage burn can be a risk. I have also been using the harpin material for good blackspot control, but it does not appear to have much influence, if any, over rosette. I think that early detection and treatment is a key help for this problem, like cancer. If it gets too far along, the plant will probably be lost. I am also wondering if an interferon-like material would be a good treatment option if it could be either sprayed or maybe watered into the ground. I hope these observations help this situation somehow.

As the originator of the one cane removal technique, I can tell that it works sometimes. Sometimes is a whole lot better than never. One scientist has said to me that how can you tell it doesn't come back. I have responded to him, after ten years of good healthy growth, that should be enough. I don't think it works for fall infected hybrid teas as I didn't save any of mine that got fall infections that I saw the following spring. The other thing I do is check with a microscope to see if the infected bush is teaming with eriophyid mites. Mine aren't. I don't use insecticide or acaricides and I see beneficials at the microscopic and visbile to the naked eye sizes. Here's my ebook about RRD/RRv for those who haven't seen it before.
