HIGH RESIDUAL EFFECT AND LOW OFF-SITE MOVEMENT AUXIN HERBICIDE FORMULATIONS

摘要

The present invention generally relates to high residual effect and/or low off-site movement anionic herbicide formulations and, more particularly, auxin herbicide formulations. Generally, the formulations of the present invention include an anionic herbicide (e.g., an auxin herbicide), a particulate sorbent (e.g., silica), a cationic surfactant, and water.

1. An aqueous herbicidal formulation, the formulation comprising:
an anionic herbicide, a particulate sorbent, and a cationic surfactant, wherein: the cationic surfactant is bonded to the particulate sorbent and the anionic herbicide is bonded to the cationic surfactant bound to the particulate sorbent, the particulate sorbent has a silica content of at least about 50 wt. %, and the concentration of anionic herbicide is at least about 0.1 wt % a.e.
