Development Dynamics of Punica Diseases in Absheron District of Azerbaijan

Abstract

The article describes the dynamics of the development of diseases of Punica in Absheron district. According to the methodology, visual inspection (5-25) of leaves, branches and fruits was carried out on 4 sides of the tree sample. Recorded samples of flower leaves, branches, stem bark and infected fruits were delivered to the laboratory; signs of the presence of pests and diseases: darkening, puncturing, spotting, drying, rotting, wilting, etc. Microscopic analyzes were carried out to determine species composition by recording characteristics. Using the method, the species composition of pomegranate mushroom seedlings was determined. Disease samples collected and delivered to the laboratory were analyzed according to the relevant methodological rules. A photograph of the pathogenic fungus spores was taken under a microscope. Under laboratory conditions in a thermostat, the development of ascospores of perithecia of the Sphaceloma punicae Bitanc. et Jenkins, which is a widespread disease of pomegranate, was partially controlled. When studying the spread of diseases affecting pomegranate plants in the region, route observations were carried out 3 times at 4-5 stations in the region at different stages of the growing season. At this time, visual observations were made of pomegranate bushes planted in different places (private courtyards and other enterprises, parks and roadsides).
