Abstract


Harmful pathogens immune actions need to establish protective measures against the introduction into the country of organisms harmful to plants or plant products, respectively orgnismelor quarantine and against their spread. The experiment was conducted in experimental 2010, under the test conditions of a tomato farm located in the County of Alba, commune Răhău respectively. In the experimental period, the dependence of the degree of attack of septoriosis in tomatoes and registered thermic and pluviometruc regime from the month of April up to September, representing a negative trend and a positive trend, respectively, but it does not respect linearity The value of the correlation coefficient between septoriosis attack and temperature is negative and moderate R = -0.442, representative for 19.50% of the analzyed culture, and correlation coefficient between septoriosis attack and rainfall is positive and moderate R = +0.488, representative for 23.80% of the analzyed culture.
