This invention discloses a controlled-release solid film formulation for pesticides, its preparation method, and its applications. This invention upgrades pesticides from liquid / powder formulations to solid film formulations, utilizing the solid film to physically block pesticide drift, diffusion, and loss, reducing off-target effects at the source. Through the combined use of physical and chemical techniques, pesticides are uniformly distributed within the solid film, and the pesticide release cycle is synchronized with the solid film degradation, achieving precise controlled release. This solid film formulation is applied from the beginning of crop growth, synchronized with the plant growth cycle, providing early preventative effects through quantitative controlled release of pesticides. This solid film formulation also functions as a mulch film; its preparation process is simple and easy, it is completely degradable and requires no recycling, reducing costs. The identification method of this invention utilizes selective precipitation separation technology, achieving high pesticide extraction efficiency of 95%-98%, especially suitable for low water-soluble pesticides. The drug identification process is simple to operate: the entire process takes less than 4 hours, requires no complex purification steps, and is suitable for batch sample processing.
