Active ingredient

TARGA component, Quizalofop-ethyl is a racemate with an asymmetric carbon atom at the α-position of the propionic acid moetiy. The active isomer is the R enantiomer, which is known as Quizalofop-P-ethyl.

Mode of action

Quizalofop-P-ethyl is hydrolyzed in plant to Quizalofop-P (acid form of Quizalofop-P-ethyl), which was proven to be an inhibitor of fatty acids synthesis through acetyl-CoA carboxylase (ACCase) inhibition.

Targa is a systemic herbicide. It absorbed through the treated foliage reaches to the meristem tissue within 24 hours and stops the growth of weeds by inhibition of ACCase in meristem tissue.


Quizalofop-P-ethyl selectively controls only grass weeds from other plants. While Quizalofop-P (active form of Quizalofop-P-ethyl) inhibits the ACCase from grass family (gramineous) plant, it does not affect the ACCase from other than the grass family plant, so it is highly safe for non-gramineous crops.

Targa has excellent crop selectivity and can be sprayed over the top of weeds and crop.
