Abstract
Raspberry cane decay disease are the major problem in its production by reducing yield and lifetime of orchards. This disease cause a several disease-causing agents, and the most important is Didymella applanata, causal agent of raspberry spur blight. With regard to the biology of the pathogen fungicide use postharvest is not efficient enough because pathogen can infect raspberry far earlier. Therefore, the aim of this study is testing the efficacy of newer organic fungicides applied before and after the harvest raspberries and mutual comparison thereof on biological efficacy. The results show that the tested fungicides exhibited very high efficacy against D. apllanata on the raspberry leaves and the canes (from 83.0 - 96.5%).
