I found this great Reuter’s Seeds catalog, Spring 1954. It’s especially notable for offering “DEENATE” 75-W: a wettable powder containing 75% DDT. Or 50% DDT wettable, 2 pounds per 100 gallons water, a 50 lb. bag for $17.00. There’s also Dupont Garden Dust, 5% DDT, Rotenone, Zerlate, and Fermate. 1 lb. can for $1.25. And “All Insecticides can now be Mailed.” They provide a handy Parcel Post Rates chart.
