Abstract

Hazelnut (Corylus avellana L.) is an important agricultural crop for Georgia and one of the main agro-export products. Significant
reductions in hazelnut production in recent years and a deterioration in its quality have necessitated certain research measures. Based on the three-year study conducted in 24 sample plots of hazelnuts in Samegrelo, Guria and Kakheti Regions, a wide range of hazelnut diseases is revealed. In particular, 18 pathogenic microorganisms were isolated and identified on hazelnut stems and fruits. Fifteen of them are fungal, one - bacterial, and two - viral pathogens. The incidence of each pathogen and the three-year average disease prevalence rates are determined.
