Abstract

Fourth instar Douglas-fir tussock moth were used to assess the residual toxicity of 10 insecticides applied to Douglas-fir seedlings. Among the 10, carbaryl compared most favorably to DDT. Rainfastness of the insecticides was tested by means of a rainchamber. Permethrin, diflubenzuron, and carbaryl were least affected by simulated rainfall, while acephate and trichlorfon were seriously and adversely affected.
