Abstract:

The objective of this research was to evaluate the effect of tow fungicides vis. Defazeem (carbendazim 50%) and Agri sin (thiophanate methyl 70%) on the mycelia growth and conidia spores germination of a local isolate of Botrytis fabae in vitro at Plant Protection Department, Faculty of Agriculture, Tishreen University, during 2017-2018. The same concentrations of each fungicide were used, they ranged from 0.001 to 100 part per million (ppm) (active ingredient) within the nutrient medium (PDA or PDB), according to completely Randomize Design with three replications. The results showed that the tow fungicides had significant effects in inhibiting the radial growth and spores germination, but carbendazim efficacy was significantly more better, because it could inhibit radial growth and spores germination 100 % by the concentration 1 ppm, but it needed 10 ppm, to achieve that efficacy by thiophanate methyl.
