A Capsule Suspension (CS) formulation is a combination of an active ingredient encapsulated in polymer shell suspended in water with a dispersant and wetting agent.
CS formulations remain one of the most advanced formulation types for crop protection products worldwide. These are typically next generation formulations. When CS formulations are diluted with water in the spray tank they form a spontaneous suspension, with particles in the size range of 0.1 to 20µm. When sprayed, the dilute emulsion gives a uniform and accurate application of active ingredient on to the crop, which is essential for effective pest control. It is possible to use CS formulations to give controlled or delayed release of pesticides as well as provide better protection against toxic active ingredients or prevent degradation of material.
