For the first time in Azerbaijan pathogenic viruses, mycoplasmas, bacteria, fungi, and chromista occuring on and within the plants (tomatoes (Solanum Lycopersicum L.), potatoes (Solanum tuberosum L.), eggplant (Solanum melongena L.), peppers (Capsicum annum L.)) belonging to Solanaceae family were revealed and registered. The species recorded and grouped by modern systematics and the types of the diseases have been determined. Cladosporium fulvum Cooke, Oidium Lycopersicum is a widespread disease of tomatoes grown indoors in the past 5 years and causes yield loss. The spread of these diseases, distribution conditions, and yield loss were studied. Environmentally-friendly control of these diseases has been developed. The integrated plant protection system used agricultural, biological methods to increase the disease resistance of crops. The degree of plant damage and microscopic characteristics of pathogens were studied. The morphological characteristics of the pathogen inform about specific changes and the occurrence of a new specialized race.
