A dispersant for pesticides is a crucial adjuvant component primarily used in formulations like wettable powders, water-dispersible granules, and suspension concentrates. Its core function is to ensure that hydrophobic active ingredient particles can rapidly disintegrate, uniformly disperse, and form a stable suspension system in water. The dispersant molecules adsorb onto the pesticide particle surfaces, creating an electrostatic or steric barrier that effectively prevents particle agglomeration and sedimentation. This characteristic is vital for practical application: it guarantees uniform concentration of the spray solution, prevents nozzle clogging, and ensures even coverage on plant surfaces, thereby enhancing pesticide efficiency and control effectiveness. Furthermore, excellent dispersion stability prevents precipitation and caking during storage, ensuring product shelf-life stability and application reliability. It is an indispensable functional component in modern pesticide formulations.
