Both sprays and dusts were used from 1936 to 1938 incl. on trellis peas grown in the coastal area. Satisfactory control was obtained with a spray containing rotenone 1 part in 10,000, wetting agent (Aresket 241), 1 part in 660, and fish oil soap 1 part in 440 applied at 300 gal. per acre. Insecticides applied in a dust form in 1937 and 1938 included nicotine, rotenone, and Loro. A dust containing rotenone 0.75% and vegetable oil, 4% gave the most satisfactory control. Loro produced a good kill but caused slight burn. The control obtained with rotenone plus a wetting agent was inferior to that obtained with rotenone plus oil or Loro. Nicotine was also inferior.
