Italian ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) is one of the most troublesome weeds with respect to herbicide resistance selection. Some reasons for this are the numerous documented cases of multiple and cross herbicide resistance and some of the biological characteristics of this species, such as wind cross-pollination...

Scouringrushes (Equisetum hyemale L.; E. xferrissii Clute; E. laevigatum L.) are ancient perennial seedless vascular plants historically associated with wetlands, low-lying roadsides or field margins with more plant available water. There has been little research conducted on scouringrush species in the context of agricultural production because traditional farming practices confined...
Centaurea solstitialis L. (yellow starthistle) and C. × moncktonii Britt. (meadow knapweed) are members of the genus Centaurea in the Asteraceae family. Both species have become serious management concerns as invasive species in North America, often displacing native vegetation and costing land managers millions of dollars to eradicate. Seven plants...
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...

Japanese knotweed is an invasive perennial shrub that dominates riparian
ecosystems. Effective management techniques are currently limited to repeated annual
herbicide applications and there is little science-based information about which control
tactics result in the greatest management success. Restoration of invaded sites to a
functioning riparian plant community is needed...
Annual ryegrass, or Italian ryegrass (Lolium perenne spp. multiflorum), has been the most stable, in terms of acres, grass produced for the past 25 years in Oregon. Increased interest in Italian ryegrass as a cover crop has increased demand for quality seed. Ideal Italian ryegrass cover crop cultivars are named...
Olive production potential in Oregon was researched in a multi-disciplinary approach, including a grower survey, a propagation greenhouse study, and a field study, from 2018 through 2020. The Oregon Olive Grower Survey was designed to collect information relating to orchard establishment and management practices, knowledge and understanding of these practices,...
With the expansion of the Tillamook Creamery, in Tillamook Oregon, to double or more
its cheese production, the demand for milk presents an economic opportunity for the member
dairies of the Tillamook County Creamery Association. Before area dairies can expand their
herd size to increase milk production for the creamery,...
Methane is the most abundant organic chemical in the
earth's atmosphere. Its abundance in the atmosphere is
increasing with time and has reached levels not seen in recent
geological history. The methane is produced both naturally, and
anthropogenically. One of the sources of anthropogenic methane
is manure from domesticated animals....
