Six bite the dust from RRD

16 years ago

I just dug up my sixth this year from rose rosette disease. I need some sympathy please. I plan on replacing them as usual. I guess over the last 8 years I have dug up 12 or so. I live in mid-Missouri in the middle of farmland so there are lots of multifloras around I myself have round-uped and removed a couple of giants that bordered our property. I feel like I don't see the beautiful blooms anymore as I am constantly looking for suspicous growth. I need to remind myself to smell those roses too. I do have an question/observation: Since the mite most likely moves and infects during hot dry months like July and August, wouldn't any of the RRD I saw this year in May and early June be a result of infection from last year? And if so how could that RRD growth be at the tips of the plant in June when I pruned off to at least shin high in April this year? Where did those mites come from this early? Or did I just miss this RRD last year and just now seeing it and the plant is already a goner. I understand if the RRD growth is coming from the roots right now--then the plant was infected last year. I do spray with Cygon plant and all plants within 4 feet when I find RRD. I also follow the 3 strikes and you are out rule and I sterilize between cuttings. I have saved 3 or 4 plants over the years when I cut the RRD infected cane to the ground when I first see it. I have never saved a plant that had RRD canes coming up from the root. Another observation: I have found plants against the southern wall (which has most of our prevailing winds) is the kiss of death and any plants that in a breezeway like area get it first. The ones that are protected from the winds by buildings have no problem. Another climbers have a tough time with RRD wherever they are, due to the fact their canes are up high in the air and catch the mites on the winds.
