Folpet

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.

[1] As of December 2019[update] 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.
