Abstract

The effect of sulfonylurea (SU) acetolactate synthases (ALS) inhibitors (chlorsulfuron and triasulfuron) and their 13 guanidine and 7 azole derivatives was studied on 17 fungal and 21 plant species. The efficacy of chlorsulfuron and triasulfuron against Fusarium oxysporum and Thielaviopsis basicola was higher than carbendazim. Two azole derivatives were highly selective for maize. The antifungal activity spectrum of both guanidine and azole derivatives differed from that of chlorsulfuron and triasulfuron, and did not exert notable antifungal activity in vitro. However, they had significant anti-Fusarium efficacy on rye that surpassed that of carbendazim.
