Fumigants, Sprays & Protectants
The Douglas agriculture division has been offering trusted commodity protection for over 100 years.
Guarding America’s Grain for Over a Century.
Ever since its beginning in 1916 and continuing today, Douglas has specialized in offering 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.
With distribution throughout the U.S., we expertly serve 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. We maintain all federal and state regulatory registrations for our pesticide labels.


Douglas ProTech’s Fumigants, Sprays & Protectants:
- Solve the problem of product preservation before going to market.
- Protect and sanitize commodities in storage, serving a vital role in food production.
- Maintain the value of stored commodities, ridding pests that would potentially ruin or significantly reduce their value.
- Are extremely useful just after initial harvest to eliminate pests from current commodity harvested to be stored, and to prevent infestation of commodities already in storage.
