Description
Propanil (3,4-dichloropropionanilide) is an acetanilide post-emergency herbicide with no residual effect. It can be prepared by reaction of 3,4-dichloroaniline with propionic acid in the presence of thionyl chloride. Propanil is in toxicity class II - moderately toxic, due to its potential to irritate eyes and skin.
Propanil functionalizes by the inhibition of RNA/protein synthesis and the inhibition of anthocyanin. Propanil is used to against numerous grasses and broad-leaved weeds in rice (mainly), potatoes, and wheat. It is typically applied aerially. propanil is used
as a rice herbicide. The resistance of rice plants toward
propanil has been found in an enzyme aryl-acylamidase
that rapidly hydrolyzes the herbicide. This enzyme can be
inhibited by carbamate insecticides, and this can lead to
an increased propanil phytotoxicity (38).

Uses
Propanil is a a widely used herbicide. Propanil is used mainly to control weed growth in rice fields. Postemergence herbicide, especially for rice
culture; nematocide. Selective preemergence and postemergence herbicide used to control many grasses
and broad-leaved weeds in potatoes, rice and wheat.
