In early May of 1969 a corn screening trial was established on the East Farm Experiment Station near Corvallis. The purpose of the trial was to determine the effectiveness and safety of a series of experimental herbicides.
The following summaries of results from experimental work with herbicides in horticultural crops cover work completed in 1967. Crops included are bush snap beans, red beets, direct seeded broccoli, cucumber, summer squash, strawberries and nursery rhododendrons. In general, weather conditions were warmer and drier than usual during the 1967 growing...
In herbicide plots on tree fruits in the Willamette Valley and at Hood River there has been a consistent correlation between weed control effectiveness and tree growth in young orchards. This appears to be particularly true of weed control during the spring and summer obtained from spring applications as compared...
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
