One or more of 3 commercial samples of DDT, 3% DDT in an inert carrier, a spray containing 5% DDT and a wetting agent, and DDT concentrate, were used as dusts or sprays in small scale tests against 20 spp. of insect pests: American cockroach, bean leaf roller, a blister beetle, cabbage insects, Colorado potato bettle, corn leaf hopper, cowpea weevil, garden flea hopper, Harlequin bug, melon and pickle worms, red flour bettle, rice weevil, squash bug, Southern armyworms, spiraea aphid, and termites. Concs. of DDT in the dusts ranged from 0.6 to 5% and in the sprays from 1 to 8 lbs. per 100 gal. The tests showed DDT to be equal or superior to the standard insecticides, derris (4.2% rotenone) and pyrethrum (1.2% total pyrethrins), with which it was compared. Two applications, 7 days apart, of 8 lbs. of 5% DDT in 100 gal. H2O caused no injury to young beans, peas, pumpkins, Swiss chard, or collards. Two applications of a 1% suspension of DDT concentrate caused no injury to young beans, pumpkins, Swiss chard, potatoes, or collards.
