The main fungal diseases of roses in Abkhazia and protective measures

Abstract

The genus Rosa includes more than 250 wild species and varieties and many cultivars and hybrids grouped into several classes. Persia (modern Iran) is considered the birthplace of the rose.

Rose is a member of the genus Rosa (Rosehip). This is one of the most popular deciduous and evergreen shrubs used for decorative purposes everywhere: in urban landscaping, in parks, gardens, in private gar­dens. Roses have beneficial properties due to the high concentration of essential oils, which leads to the use of this plant in perfumery, cosmetology, medicine and even the food industry. Currently, roses are cultivated in almost all countries of the world. About 10 differ­ent rose species are grown in Abkhazia. The humid cli­mate of the region contributes to the development of infectious diseases, primarily fungal ones, and there­fore roses are quite often affected by various myco­ses. An important condition for the successful cultiva­tion of roses is the early detection of phytopathogens and timely control of them. The article briefly provides an overview of the biological characteristics of phyto­pathogens, data on the distribution and severity of the main fungal diseases of roses in Abkhazia. Black spot, rust, powdery mildew are the most dangerous and most common infectious diseases of roses in this region. The article emphasizes the need for fungicide treatments in protecting rose bushes against the diseases in ques­tion and the effectiveness of pruning, collecting and de­stroying affected plant residues.
