Spurblight causes purple patches on raspberry canes. Discover how to manage this disease and protect your crop.Quick facts. What is spurblight? Symptoms. Control. Biology. Spurblightcontrol is aided by good air circulation through the canes. To achieve this, keep the rows quite narrow and the canes spaced well apart. Controlling weeds is also important. Spurblight can be minimized in raspberries by rigorous pruning to control the number of canes in a row, so that the overall row width does not exceed 14 inches at the base. Dead canes continue to produce conidia and remain a source of infection for several years. -3-. Control of SpurBlight and Cane Blight. Spurblight is caused by the fungus Didymella applanata. Spurblight occurs only on red and purple raspberries.Control. Figure 2. Spurblight symptoms on red raspberry leaves. Furthermore, the prevalence of the disease decreased by two times or more. relative to the control. The biological efficiency of the experimental bio preparation Phytop 26.82 reached. Conversely, azoxystrobin, pyraclostrobin, and fluazinam showed very low efficacy (13.7-37.8%) in control of raspberry spurblight.Spurblight of raspberry. Mycologist, 20(2), 77. In order to control the causal agent of spurblight of raspberry (Didymella applanata), the efficacy of five conventional fungicides and two biofungicides was evaluated during 2009 and 2010...
