Thiophanate-methyl is an organic compound with the formula C₆H₄(NHC(S)NH(CO)OCH₃)₂. The compound is a colorless or white solid, although commercial samples are generally tan-colored. It is prepared from o-phenylenediamine. It is a widely used fungicide used on tree, vine, and root crops.^[1] In Europe it is applied to tomato, wine grapes, beans, wheat, and aubergine.^[2]

Methods for its analysis have received considerable attention.^[3]^[4]^[5] It is commonly used to treat botrytis bunch rot and gray mold caused by Botrytis cinerea strawberry in California.^[6] Thiophanate-methyl acts as a fungicide via its primary metabolite carbendazim.
