THE INFLUENCE OF THE TREATMENT WITH FUNGICIDES ON THE PHYSIOLOGICAL PROCESSESIN LYCOPERSICON ESCULENTUM MILL. PLANTS ATTACKED BY THE ALTERNARIA SOLANI SORAUER

The influence of the treatment with fungicides on the physiological processes were observed in Lycopersicon esculentum Mill. plants cultivated in the climatic conditions in Oltenia region.The physiological researches were performed on August 23th 2021, both for plants treated with Dithane M-45 (0,2%), in four phases, at 7 days interval and also for the plants attacked by AlternariasolaniSorauer, in which treatments have not been performed.In the leaves of the plants attacked by the pathogen it was observed that the physiological processes’ intensity (photosynthesis and transpiration intensity) is lower as a result of the effects produced by the pathogen manifested by the appearance of dark brown spots with closed concentric rings.The content in chlorophyll is higher at the analysed leaves after performing fungicide treatment, thus existing a positive correlation between this content and the photosynthesis intensity. &nbsp
