CHB-HS, with gibberellic acid and 3-indolebutyric acid as actives, is a specially designed plant growth regulator to increase weed susceptibility to selective postemergence herbicides. Optimum weed control is obtained when CHB-HS is applied to actively growing weed seedlings. Thorough coverage of the weed seedlings is essential for optimum control.
