Benomyl (also marketed as Benlate) is a fungicide introduced in 1968 by DuPont.It is a systemic benzimidazole fungicide that is selectively toxic to microorganisms and invertebrates (especially earthworms), but relatively nontoxic toward mammals.

When they were the only fungicides used, pathogens became resistant after two to four seasons; when mixed with other fungicides, resistance developed more slowly. [ 3 ]
