Benthiocarb

Benthiocarb is a thiocarbamate cholinesterase inhibitor used as an herbicide. Benthiocarb is almost always used to control the weeds around rice crops, but its effectiveness is not specific to just rice crops.[3] The benthiocarb molecule is an organic molecule containing a phenol bonded to a chlorine atom.
