What is Pyrithiobac-sodium?

Description

Pyrithiobac-sodium is a post-emergence herbicide for the control of broad-leaved weeds in cotton and other crops. It has a high aqueous solubility, is non-volatile and, based on its chemical properties, it is very mobile and has high potential to leach to groundwater. It is generally moderately persistent in soil systems but tends to be non-persistent in aquatic systems. It has a low mammalian toxicity but may bioaccumulate.

The Uses of Pyrithiobac-sodium

Herbicide.

The Uses of Pyrithiobac-sodium

Pyrithiobacsodium can be used as pesticides of interest in agricultural crop.

Definition

ChEBI: Pyrithiobac-sodium is an organic molecular entity.

Mechanism of action

Pyrithiobac sodium acts on Acetolactate Synthase enzyme of the plant leaf and controls the growth of weeds and Quizalofop ethyl acts on acetyl-CoA carboxylase (ACCase) enzyme which stops the only grassy weed growth.
