Funga stop proved to be the most effective in inhibiting by 72 to 76% the mycelial growth of this pathogen on PDA media after incubation for six days at 25 °C. Biocont-T also limited its development by 37 to 63%. However, Polyversum showed a very little activity in controlling this fungus in vitro. All bio-fungicides reduced disease incidence compared to the untreated control. Funga stop and Biocont-T were the most active during the bioassay. Whereas, Polyversum had a lesser effect in controlling this disease.]]>Anonymous,20032nd Edn.,pp: 206pp: 206Ayed, F.,2005Fusarium wilt of potato: Cultivars behaviour and chemical and biological control.]]>2005Ayed, F., M.
