Note: Click on photograph for larger size. I am located near Ithaca, NY in the United States, zone 5-ish. I am hoping someone here will be able to identify the problem and/or suggests ways I can either stop it or at least prevent it from killing my plants in the future. I have never had to worry about plant diseases before so I am not at all sure what to do next. But now the replacement appears to be dying from whatever killed the first plant. The first plant I received eventually died and Burpee replaced it. This is actually my second time trying to grow this raspberry. I have tried pruning the affected leaves off, but the problem still spreads to other parts of the plant. Usually crinkling is accompanied with yellowing. But then leaves started curling and eventually dying (pictures below). Viruses Raspberry Mosaic Virus and Leaf Curl Virus are common causes of leaf crinkling. Prune out infected twigs and branches may provide adequate control. Natural Control Pruning to promote better penetration of sunlight and air movement may help. A white threadlike fiber will form in advance of dead areas. The first few weeks everything seemed to be fine. Leaves wilt, curl and turn brown, usually in the shaded part of the plant. When I received the plant I transplanted it to a larger container to allow it to recover & develop more before planting it in a permanent location. My understanding is that this raspberry is a variety released by Cornell about 3 years ago. Burpee lists the plant as Crimson Night Raspberry PPAF. About a 1 1/2 months ago I ordered and received a live raspberry plant from Burpee.
