Extract

The herbicides 2,4-D and 2,4,5-T are used extensively in the Western States for killing Ribes, the noxious plants that spread the destructive blister rust (Cronartium ribicola Fischer) to white pines (Pinus L.). Tests of the thermal fogging unit here described relate to the broadcast application of low dosages of 2,4-D as a wet oil-fog designed to defoliate and damage ribes plants without significantly damaging associated white pines. Tests were made at Stockton, and near Pescadero, Calif., in 1950.
