EFFICACY OF FUNGICIDES AGAINST OF POWDERY MILDEW DISEASE OF RASPBERRY PLANT

Abstract

In this study, it was established that the causative agent of powdery mildew in raspberries is the fungus Sphaerotheca macularis Magnus. Fungicides containing flusilazole, difenoconazole + cyflufenamid, and penconazole were tested against powdery mildew in raspberries. The best effect of the fungicides against powdery mildew was observed during the period of the initial flower bud formation and before flowering. The highest biological efficacy was recorded for the fungicide Cideli Top 140 EC (125 g/l difenoconazole + 15 g/l cyflufenamid) at a rate of 0.7 l/ha, achieving a biological efficacy of 90.0%.
