Abstract


Due to the increasing impact of clime influence upon tomato diseases, our study aimed to identifying the extent of the most important tomato pathogens of fungic and bacterial origin, (Phytophtora infestans, Alternaria solani, Clavibacter michiganensis subsp. Michiganensis), and extent of risks exposure to this pathogens., in a genuine tomato variety in specific pedo-climatic conditions of Transylvanian Plane, Romania. For late blight are reported the biggest attack degree average values by entire experimental period, whatever fertilized (33.88%) or not fertilized variant (36.50%), while for early blight the smallest, significant different (p < 0.05) in fertilized variant (20.88%), compared to not fertilized (22.95%).
