Synthetic herbicides with excipients for recovering from shock after instillation and methods for preparing these products

Abstract

The invention proposes a plant protection product. The plant protection product includes pretilachlor, pendimethalin, and a herbicide of choice derived from an amino acid inhibitor or a protoporphyrinogen oxidase inhibitor (PPO). The product contains a mixture of optionally linear copolymer polysaccharides obtained from brown algae (Phaeophyceae) or Ascophyllin iodide. The invention also proposes a method for preparing the plant protection product. In this method, prctilachlor, pendimcthaiin, herbicides, and excipients are mixed to obtain a pre-mixture. To this pre-mixture, water is added to obtain a blended mixture.
