DEVELOPMENT OF A SAFE, EFFECTIVE SPACE TREATMENT FOR NAVY SUBSISTENCE WAREHOUSES.
Abstract
Laboratory tests showed that (1) weekly applications of dichlorvos vapor, applied and maintained at a concentration of 4 micrograms per liter of air for about 6 hours, provide an effective space treatment against most species of stored-product insects, (2) vapor applications provided more uniform distribution of the insecticide than aerosol applications, and (3) residues on commodities from vapor applications were much lower and dissipated more rapidly than residues from aerosol applications. Since a method for applying insecticide vapor in sufficient quantities to treat a large warehouse was not available, laboratory personnel developed a vapor dispensing unit for this specific purpose. Field tests were conducted with the vapor dispenser and an automatic aerosol dispensing system in a number of government subsistence warehouses. These tests showed that the vapor dispenser is superior to the aerosol system and will provide and maintain the desired vapor concentration of dichlorvos in large storage areas. (Author)
