Alternaria solani, which causes early burning disease in all areas of tomato farming worldwide (Ell. And Mr. Martin, ask me. This causes significant product losses. In this study, the effects of 8 endofit bacteria (EB) (T2K2, T26Y1, G116S2, T13K1, V17G2, V30Y3, V38K1 and V40K2) on the early burning disease caused by A. solani and on the morphological development parameters of tomatoes were studied. In the first phase of the study, the EB isolates looked at the plant morphological development in-vivo and the antagonistic effects against A. solani in-vitro. The second stage was successfully completed with the EB isolates. At this stage, the effects of selected EB isolates on the disease and the development parameters of infected plants with A. solani were assessed. It is estimated that EB isolates undermine the disease by 11-53%. In-vivo tests, the isolates T13K1, V40K2 and V30Y3 were the most effective applications against the disease. Also, V40K2 isolate has increased the development of plants under illness and disease stress in general. Following this insulation, the root age weight of the G116S2 insulation in uninfected plants (0.49 g) and the extraction length (59.17 cm) in infected plants increased, while the T13K1 insulation in uninfected applications increased the extraction age (3.14 g) and the dry weight (0.34 g). In infectious applications, negative controls (K(-)) indicate that EB isolates have a positive impact on plant development, while positive controls (K(+)) indicate a difference. As a result, it has been determined that used EB isolates have the potential to reduce pesticide and synthetic fertilizer intake, but this effect may vary according to the pathogen-endofit bacterial interaction.
