| 摘要 |
Dry, water-soluble powder, substituted heterocyclic acid, substituted phenol herbicidal compositions, combinations thereof, or in combination with phenoxy and/or benzoic acid herbicides, are prepared by grinding and dry blending the herbicide in acid form with a dry, particulate solubilization medium selected from the group consisting of diammonium phosphate, dipotassium phosphate, disodium phosphate, trisodium phosphate or tripotassium phosphate. At least about 1 mole of the medium is provided for each mole of active herbicidal agent in the initially dry blended mixture. The dry blended mixture may be packaged in suitable containers such as paper bags, and added directly to a quantity of water to form a solubilized herbicidal formulation containing from about 0.1% to about 2-1/2% of the active herbicide and which is suitable for direct application to vegetation to be controlled.
