Douglas ProTech

Ever since our beginnings in 1916 as Douglas Chemical & Supply Company and now today as Douglas ProTech, we’ve continuously offered products that protect America’s commodities from insects and pests. Douglas ProTech manufactures and distributes time-tested fumigants, sprays and protectants that help protect our food throughout the entire supply chain — on the farm, in storage and transportation, and during manufacturing and distribution.

Our PH3 Aluminum Phosphide fumigant protects stored commodities from damage by insects, solving the farmer’s needs of product preservation before going to market. Our Max Kill Dusta-Cide 6 is a proven 6% malathion dust formulation that provides residual protection against insects in uninfested, stored grain. And our Max Kill Vapo-Cide is a versatile, quick-acting liquid insecticide that can be applied as a fog or spray to provide control against exposed stages of most stored-product insects.

With convenient distribution across the USA, we expertly serve a range of food processing companies including grain storage, flour & rice mills, food manufacturers and commodity warehouses. We’re proud to maintain the quality and customer service our family of distributors and applicators have come to expect and depend on for over a century.
