Weeds in snap beans drag down yield and contaminate products sent to processors or markets. They may even make it impossible to harvest the crop mechanically. It is worth the effort to be proactive when managing weeds in row crops. Proactive rather than reactive approaches are essential to successful management...
Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with CO₂ precision plot sprayers. Unless otherwise indicated, preplant...

Results from vegetation management trials involving horticultural crops conducted during the past year are compiled and reported by faculty members of the Oregon Agricultural Experiment Station, the Oregon State Extension Service, and colleagues who cooperated from adjacent states along with local enterprises. This work was conducted throughout Oregon and involved...

The goal of this project was to develop and test non-herbicidal techniques that remove nonnative
plant or weed seeds from the top 2 inches of the soil. The Nature Conservancy (TNC) is
currently restoring prairies in the Willamette Valley. Some areas of the Pacific Northwest have
already seen loss of...
The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...
SUMMARY
Both Impact and Laudis are effective grass killers. The weed control spectrum of these herbicides was enhanced by the addition of atrazine. Both are weak on purslane.
The data from the Stayton I experiment with Coho sweet corn suggest that corn yield may have been reduced by as much...
