Abstract


The trial has been developed during a two years period, 2013 and 2014, on tomato cultures, and factorial analysis (Principal Components Analysis) was implemented. The factorial analysis shows that fertilization and humidity has biggest influence on Clavibacter michiganensis subsp. michiganensis attack degree, while humidity and temperature influences the most Phytophtora infestans and Alternaria solani attack degrees. The Phytophtora infestans attack degree recorded the biggest attack in climatic conditions specific to the experimental site, followed by Clavibacter michiganensis subsp. Michiganensis, and Alternaria solani.
