Infobox references

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.

Resistance

(As of December 2019) folpet resistance is still unheard of due to its multiple effects. However, in 2001 some degree of cross-resistance was reported in iprodione-resistant South Africa n Botrytis cinerea on grape.
