Folpet is the tradename for the organic compound with the formula C6H4(CO)2NSCCl3. It is a fungicide derived from phthalimide (C6H4(CO)2N-) and trichloromethylsulfenyl chloride. The compound is white although commercial samples can appear brownish. It is structurally related to Captan, which is also a trichloromethylsulfenyl-containing fungicide.[1]

Resistance

As of December 2019 folpet resistance is still unheard of due to its multiple effects.[2] However, in 2001 some degree of cross-resistance was reported in iprodione-resistant South African Botrytis cinerea on grape.[3][4]
