ABSTRACT
This experiment followed the pyramid effect influention about tomatoes breed plants process as much below the appearance of total weight and component elements ( leafs). The cultivated plants protection influenced precocity demonstrated through the rhythm of growth and production obtained. In the tomatoes plants case the host-pathogen pathosystem were represented of present fungi as Alternaria dauci f. sp. solani, Septoria lycopersici and Phytophthora infestans which were very viperous forms caused varied damages between 0,2-12 in the pathogenetic case Alternaria dauci f. sp. solani, between 7-12 in the pathogenetic case Septoria lycopersici and Phytophthora infestans with intensities of attack contained between 75-100, fact drove to the drying completes the leafs in the case of untreated tomatoes to Rada cultivar and to Romec 554 J cultivar
