Also, I didn't address this, but I got this from Ashdown in 2009, so I it is an own root plant. At least that is my understanding. But I don't think there would be anyway for me to separate the roots of the diseased from the rest, because the most recent new growth is almost in the center, while the other section is on the far left. That would seem to me to indicate that too much of it is infected to even consider separating it. I'm not sure I have much confidence in it surviving anyway (especially with me doing a chopping job on it). I think I might be better off to bite the bullet, and proceed with another plan. I can't imagine the frustration of hacking down a row of productive blackcurrents 3 times. That had to be extremely painful. One thing this has done is motivate me to work on other areas of the lawn that I planned to take over anyway. My husband has been a bit resistant, but I have shown him enough nice examples of what can be done that he is now on board. I have about 13 boxwood, a cedar, and many other things that I need to plant now anyway. I've learned a great deal, and that is one of the things I love about gardening anyway-endless number of things to learn, and some aspects are just trial and error ultimately. You can't succeed if you don't try, and there are bound to be failures no matter what you do.

Maybe we can spray the rrd mites with roundup on their way to the sea! There was a guy at OSH yesterday asking the salesman if roundup would work on mice and rats.... 24

Jax, That fortuniana survived for a decade without catching a mite was the hope, that and its distance from R. multiflora on the part of both of its parents. I wasn't going for a genetic salvation, but I hoped that there might be a cultural barrier tied to the preferred growth times of banksia and laevigata. I had hoped that the 'off' growth cycle of fortuniana might be a saving grace, that it grows through winter when the mites aren't out. Mine was relatively dormant through summer, and post bloom spring pruning sufficed. An example is R. setigera which doesn't get RRD often, even though R. multifloras in the same fencerows (unsprayed with herbicides) get RRD rather easily. R. setigera just doesn't get 'that' large nor is it actively growing through summers here. Not exactly a cultural barrier , but a reduced propensity to contract the disease. There are so many instances where one rose appears to have avoided infection, and the more we know, we find that others of the same cultivar are infected. Wind tunnels with a speeded up wind speed are not practical at all (although they work). I have always expected RRD to infect all roses, but I had hoped that some barriers might exist in nature, a lesser propensity to infection for the ones that go to near dormancy in summer, ones who have a limited window of opportunity for the mites to feed on undifferentiated meristem tissue in axillary buds or at the ends of broken stems (the latter seems to be the problem here). Or maybe have really tight buds that the mite's feeder tube can't get through. As to a pest that will take out the eriophyid mite: it's out there and was described early on in the Allington, Staplin and Viehmeyer paper. The predators are conventional spider mites; in the isolation labs at the University of Nebraska they were trying to study the eriophyids, but spidermites kept getting in and destroying the eriophyid populations. Amrine and his students have also found some unnamed species of predaceous thrips will feed on erophyids AND thrips. I don't use insecticides or acaricids on my roses. I haven't in a long time.

Roundup can pass through a connected system. But despite Henry's repeated quotes of various scientific articles (usually related to edible annual herbaceous plants unrelated to roses or seedling growth in farmland) there is no real evidence that any transfer from roots to soil to roots in the sort of application we're talking about, can really harm an adjacent hardwood bush like a rose, not to mention a huge established shrub like the one we are discussing. People have been 'surgically' removing garden plants using roundup for ever. Most of it is bound rapidly to the soil (to the extent that cutting a stub and powdering with a little dirt before 'rounduping' greatly diminishes the efficacy of the herbicide) and what little may or may not end up in the rizosphere from where some may or may not be absorbed by adjacent roots has not shown any harmful effects under field conditions. Now we have discussed this repeatedly before and I'm sure Henry will come up with yet a few obliquely related articles stating that traces of roundup or the results of its decomposition in the soil have mean identified in adjacent plants (and I have no reason not to believe this) but the field experience of millions of gardeners and farmers shows you can roundup a bush with the cut and apply method with no noticeable harmful effects to the adjacent ones. If there was a problem we would know about it through collective knowledge and word of mouth even if we didn't undestand the mechanics of it. I don't challenge what the linked articles are describing, I'm challenging Henry's crude interpetation and his arbitrary chain linking of them, which is grossly exaggerating to say the least. I'm sure Henry understands very well what he's reading but when someone is on a mission anything goes. There, I have vented off. PS I have never ever sprayed roundup or any other herbicide in my garden for weed control and I don't intend to, but I have used roundup on cut stems and stubs of small bushes and large trees repeatedly when it was the only viable solution to get rid of the plant for whatever reason. PS2 In the above I don't mean to recommend the roundup method for the particular RRV suspicion problem at hand. Firstly I have no knowledge or experience of RR disease and secondly I wouldn't do it myself out of fear of passing the herbicide through a possibly connected root system which, even if it doesn't kill the mother plant, it may cause symptoms similar to RRD which, for obvious reasons, would defeat the purpose of the original effort to save the mother plant..... I just commented on the use of roundup to kill individual plants.
