Abstract


Research on the pathogen attack’s which cause diseases called spots, was undertaken in the green area of Craiova, on the assortment of flowering and ornamental plants and aimed to quantify the spectrum of fungal pathogens in the climatic conditions of 2019.

On the 13 host plants, the characteristic attack of a number of 15 fungal pathogens that caused spots produced by fungi of the genera: Diplocarpon, Sphaceloma, Phyllosticta, Lasiobotrys Clodosporium, Alternaria, Septoria, Cercosporia, Blumeriella and Venturia was reported.

The notes on the frequency and intensity of the attack, in order to calculate the degree of attack were made for each host plant and pathogen together with the diseases signaling.

The degree of attack values for the 15 pathogens that produce spots on the 13 host plants ranged from 0.03% (Phyllosticta magnoliae Sacc.) and 7.1% (Diplocarpon rosae).
