Learn about atrazine herbicide
Atrazine is a systemic selective pre-emergence and post-emergence blocking herbicide. Mainly absorbed by roots, with very little absorbed by stems and leaves. The herbicidal effect and selectivity are the same as simazine, and it is easily washed by rainwater into deeper layers of the soil. It is also effective against some deep-rooted grasses, but is prone to phytotoxicity. The shelf life is also longer.
