AI Technical Summary
Technical Problem
The existing herbicide pyrimisulfuron is difficult to dissolve in water and common solvents, leading to problems with formulation toxicity and flammability, and traditional solvents are not conducive to agricultural applications.
Method used
An improved solvent system, comprising amide solvent, co-solvent, emulsifier and pH stabilizer, is used to form an environmentally friendly emulsifiable concentrate (EC) formulation that dissolves pyrimisulfuron and improves its solubility in water.
Benefits of technology
It provides an environmentally friendly herbicide formulation that improves the solubility and safety of pyrimisulfuron, reduces the risk of toxicity and flammability, and is suitable for agricultural applications.
