Benzimidazoles are low use-rate, broad-spectrum fungicides that have been used commercially for the control of plant diseases since the late 1960’s. At the time of their introduction, they represented a ground-breaking class of fungicides with unique properties including systemic and curative activity that allowed extended spray intervals. World-wide, benzimidazole fungicides are registered in many countries on more than 70 crops including cereals, grapes, fruits and vegetables. Benzimidazoles currently commercially available include the active ingredients benomyl, carbendazim (MBC), thiabendazole, thiophanate, thiophanate-methyl and fuberidazole.
