Much of the research effort with Dacthal in 1961 was based on obtaining samples for residue analysis. Crops in these tests included broccoli, cabbage, cauliflower, onions and soybeans. Observations were made on crop response and weed control.
Several herbicides were evaluated for selective weed control in sweet corn in 1961. Various methods of application were compared and a comparison of planting depths was made to determine possible interactive effects with Eptam applications
A planting of three varieties of strawberries was made in the spring of 1959 with herbicide treatments designed to provide weed control through the normal life of the planting.
A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
