Possible description of the delivery mechanism of the CheckMate spray

research: "Polymer Microcapsules Background One of many fascinating applications of polymer microcapsules is in the area of crop protection. For example, insect pheromones are becoming viable as a biorational alternative to conventional hard pesticides. Specifically, sex-attractant pheromones can reduce insect populations by disrupting their mating process. To this end, small amounts of species-specific pheromone are dispersed during the mating season, raising the background level of pheromone to the point where it hides the pheromone plume released by his female mate."
