Hare barley (Hordeum murinum ssp. leporinum) is a cool season annual grass that invades pastures and range areas around the world. A documented weed management issue in several Oregon counties, hare barley may infest several thousand acres in western Oregon. This study was conducted to investigate the biology and develop...
Puncturevine is on the loose in western Oregon. Puncturevine is an annual in our climate, and it produces seeds that can contaminate snap beans headed to the cannery. Puncturevine also has very persistent seed with erratic emergence over several seasons. When spotted, puncturevine should be eradicated.

It is worth the effort to be proactive when managing weeds in row crops. Proactive rather than reactive approaches are essential to successful management...

Entomopathogenic fungi are cosmopolitan microbial pathogens that cause fungous diseases in a wide range of insects via spore infection. Due to their natural enemy status, they have tremendous potential for use as microbial control agents against insect pests, especially subterranean pests for which few management options are available. The clover...
Weed management in sustainable farming systems often requires the integration of several different pest management techniques. Cultural, biological, and chemical pest control efforts can be utilized to contribute to the common goal of reducing weeds in vegetable row crop systems. This research addresses how common disturbances such as tillage and...
