This 1957 progress report will be concerned with results of the use of herbicides on pole beans, sweet corn, and table beets in trials at Corvallis. The plots were evaluated for effectiveness of weed control by these herbicides as well as their effects on yield. These results are to be...
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.
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...
