The objective of this research was to study the effect of Defazeem (carbendazim 50%) and Agrisin (thiophanate methyl 70%) on the mycelial growth and conidia spores germination for five isolates of Fusarium oxysporum f.sp. lycopersici at Faculty of Agriculture, Tishreen University, during 2017 and 2018. The two fungicides were used in different concentrations ranged from 0.1 to 1000 parts per million (ppm) (active ingredient) on nutrient culture media (PDA). The results showed that carbendazim inhibited the fungus growth by 59.94% to 76.4% at 1 ppm and by 100% at 10 ppm for all isolates. Thiophanate methyl inhibited the growth by 71.73 to 81.47% at 100 ppm, and by 100% at 1000 ppm. The effect of carbendazim in conidia spores germination was medium and ranged from 37.98 to 66.75% at 100 ppm and by 100% at 1000 ppm. While the effect of thiophanate methyl was low at all studied concentrations.

Key words: Carbendazim, Thiophanate methyl, Fusarium oxysporum, Tomato.
