Removal of molluscicidal bait pellets by earthworms and its impact on control of the gray field slug (Derocerus reticulatum Mueller) in western Oregon grass seed fields

Creator:: Gavin, W. E., Mueller-Warrant, G. W., Griffith, S. M., and Banowetz, G. M.
Abstract:: Slugs are common pests of grass seed fields in western Oregon and the current focus of repeated, and often unsuccessful, efforts by growers to control them using molluscicides. Here we document rapid loss of molluscicidal bait pellets to earthworms and the resulting adverse effects on slug control. Three years of...

Impact of land use patterns and agricultural practices on water quality in the Calapooia River Basin of western Oregon

Creator:: Mueller-Warrant, G. W., Griffith, S. M., Whittaker, G. W., Banowetz, G. M., Pfender, W. F., Garcia, T. S., and Giannico, G. R.
Abstract:: Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and...

Puberty development and reproductive performance in beef heifers fed rations supplemented with Oregon by-product feeds

Creator:: Oswald, Keely E.
Abstract:: In the majority of management scenarios, it is imperative that beef replacement heifers calve at two years of age. In order to achieve this goal, yearling heifers should reach 60 to 65% of their mature body weight by 13 months of age. Feed costs represent 75 to 80% of the...

Postharvest residue management for grass seed production in western Oregon

Creator:: Hart, John M. (John Mervyn), 1947-, Anderson, Nicole P., Hulting, Andrew Gerald, Chastain, Thomas G., Mellbye, Mark Edward, Young, William C. (William Clyde), Silberstein, Thomas B., and Oregon State University. Extension Service
Abstract:: This publication incorporates 20 years of field research by OSU faculty comparing two grass-seed residue management methods: full straw load (straw is chopped and left on the field) and clean nonthermal (straw is baled and removed from the field). Comparison includes discussion of seed yield and quality, nutrient management considerations...

Trinexapac-ethyl and open-field burning in creeping red fescue (Festuca rubra L.) seed production in the Willamette Valley

Creator:: Zapiola, Maria Luz
Abstract:: Open-field burning has been an effective, economical, and widespread method of post-harvest residue management in creeping red fescue seed production in the Willamette Valley since the late 1940s. However, the use of field burning has been legislatively restricted due to air quality and safety issues. The foliar-applied plant growth regulator...

Genome-enabled discovery and characterization of type III effector-encoding genes of plant symbiotic bacteria

Creator:: Kimbrel, Jeffrey A.
Abstract:: Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...

Spring Nitrogen, Plant Growth Regulator, and Defoliation Effects on Seed Production in Two Fine Fescue (Festuca rubra L.) Species

Creator:: Anderson, Nicole P.
Abstract:: One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...

Residue management and yield characteristics of fine fescue seed crops

Creator:: Schumacher, Derek David
Abstract:: Chewings fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman] is a desired turfgrass with dense sod forming capabilities and superior shade tolerance. Thermal residue management (open-field burning) has traditionally been used to remove post-harvest residue and maintain seed yield over the life of the stand. However, alternative non-thermal residue management...

Spring irrigation management of tall fescue (Festuca arundinacea Schreb.) seed crops

Creator:: Orthel, Krista D.
Abstract:: Later maturing cultivars and increased ability to apply irrigation have led to inquiries by producers about proper irrigation management in tall fescue (Festuca arundinacea Schreb.) seed crops. The literature reveals little information about irrigation of perennial grass seed crops in general, and none about tall fescue in particular. Willamette Valley...

Effects of Biochar-Based Seed Coatings on Seed Germination and Seedling Vigor of California Brome (Bromus carinatus L.) and Blue Wildrye (Elymus glaucus L.)

Creator:: James, Matthew Scott
Abstract:: California brome and blue wildrye are important native grass species in the Pacific Northwest. However, both species have been reported to have low emergence under less than favorable field conditions. Seed coating is used to improve emergence and stand establishment of various crops. Three studies were carried out to determine...
