Burns Douglas-fir Tussock Moth Control Project, 1965. Malheur National Forest, Oregon. Photo by: James W. Hughes Taken: June 1965 Credit: U.S. National Archives and Records Administration Reference: RG# 95-GP. Records of the Forest Service. General Subject Files. Forest Service Negative Number: 513697 Note: "During the period of June 10 to July 1 , 1965, a total of 65,945 acres were sprayed with DDT for control of early-instar larvae (Perkins and Dolph 1967). Application was by helicopter and at the rate of 0. 75 pound DDT in 1 gallon of fuel oil formulation per acre. Because of public concern at this time about side effects of DDT in the environment, impact of the spray on other resources, including fish, water, soil, forage, and cattle, was evaluated by scientists working independently of the project (Crouch and Perkins 1968, Tarrant et al. 1972). In addition, a small test was made of two other candidate insecticides, Dursban, an organic phosphate, and Zectran, a carbamate." From: Wickman, B.E.; R.R. Mason; and C.G. Thompson. 1973.
