General description: | Pyrithiobac, a pyrimidinyl carboxy herbicide, is widely used for postemergence control of broadleaf weeds in cotton. It is effective against most of the dicot weeds including, pigweed species (Amaranthus spp.), most annual morning glory species (Ipomoea spp.), common cocklebur (Xanthium strumarium), and smartweed species. The herbicide acts by inhibiting acetolactate synthase (ALS) enzyme. |
