How long of a residual do the current dust formulations provide? Is the dust water-resistant?
In testing at the University of California-Riverside, our EcoPCO® D dust formula provided almost two months of activity from the active ingredient, and as Don Reierson at the University of California Riverside noted, “…there is no reason to presume that reasonably well-protected residues would not have a desiccating effect for as long as the powder remains and does not get too moist. It (EcoPCO® D) is also very active as a desiccant”. EcoPCO® D is a water-resistant dust.
