This article provides data on the main fungal diseases of dog rose in the conditions of the Tashkent Botanical Garden. The main diseases and their causative agents and signs of such diseases as rust, powdery mildew, gray rot and various spots have been studied. The results of the study were used to develop measures to combat rosehip fungal diseases. To suppress the spread of rosehip spots, Previkur SL 722 c.c. preparations were used. at two consumption rates and Falcon 46% e. The biological effectiveness of the drugs used was studied. Thus, the maximum value was noted in the variant with Previkur SL 722 v.r.k. at a consumption rate of 1.5 kg / ha, which was 90.9% on day 15, and by 30 - 86.5%. For the fungicide Falcon 46% ae. (0.5 l / ha), biological efficiency was 78.2% on day 15 and 66.8% on day 30. Against powdery mildew, we used fungicides Ridomil Gold 68% w.g. at a consumption rate of 2.5 kg / ha and powder of ground sulfur (20 kg / ha). fungicide Ridomil Gold 68% w.dg, showed biological effectiveness on leaves on day 15 - 74.8%, on stems - 71.3%, however, these indicators on day 30 were 75.2% and 72.2%, respectively , on the 45th day the indicators decreased. In the case of sulfur, 20 kg / ha, the indicators were on the 15th day, on the leaves - 71.5%, on the stems 70.6%, on the 30th day - on the leaves 71.3% and on the stems 70.6%..
