Summary
Benzimidazole fungicides are low use-rate, broad-spectrum fungicides, widely used in agriculture for pre- and post-harvest treatment for control of a wide range of pathogens. Benzimidazole fungicides were the first fungicides to be used to control eyespot in Europe from around 1974. 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. These substances are applied directly to the soil or sprayed over crop fields and hence are released to the environment. They readily penetrate plants through the roots and leaves and can directly enter natural waters by drainage from agricultural land. Most of these compounds persist in the environment after application; some even remain for years. Benzimidazoles currently commercially available include the following active ingredients:
