Isolation and Pathogenicity of Naturally Occurring Entomopathogenic Fungi to Clover Root Borer (Coleoptera: Curculionidae: Scolytinae), a Pest of Red Clover Seed Crops

Creator:: Lestari, Anis S.
Abstract:: 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...

Hybridization between yellow starthistle (Centaurea solstitialis) and meadow knapweed (Centaurea x moncktonii)

Creator:: Miskella, John
Abstract:: 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...

Effect of seed burial and vernalization on germination and growth of Bromus carinatus and its control with several herbicides

Creator:: Rojas-Calvo, Carlos Enrique
Abstract:: California brome (Bromus carinatus Hook & Arn), is considered an important weed infesting wheat and grass seed fields in the Willamette Valley of Oregon. Field and greenhouse experiments were conducted to study some biological aspects to develop more efficient management strategies. A field experiment was conducted to determine the effect...

Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

Multiple-resistant Italian ryegrass (Lolium perenne spp. multiflorum) populations in Oregon

Creator:: Liu, Mingyang
Abstract:: Italian ryegrass (Lolium perenne spp. multiflorum) is a common weed management problem in turfgrasses, cereals and non-crop areas in the United States. In Oregon, the number of populations with multiple-resistance continues to increase. To manage these resistant populations, the resistance patterns must be determined. In this study, five Italian ryegrass...

Integrated small broomrape (Orobanche minor Sm.) management in red clover (Trifolium pratense L.)

Creator:: Ross, Kyle C.
Abstract:: Small broomrape, a holoparasitic weed, is a relatively new weed introduction in the Pacific Northwest that has contaminated a limited number of red clover fields in Oregon. Greenhouse and field studies were conducted to evaluate small broomrape response to common crop and weed species in the Pacific Northwest. Host species...

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...

Hare barley (Hordeum murinum ssp. leporinum) biology and management in cool season perennial grass pastures of western Oregon

Creator:: Haavisto, Jessica Lee
Abstract:: 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...

Growth and reproduction of annual bluegrass (Poa annua) in response to trinexepacethyl or prohexadione-calcium at multiple rates and application timings

Creator:: Faletti, Matthew T.
Abstract:: Field experiments were conducted in 2002 and 2003 in the Willamette Valley of Oregon to investigate the effects of two plant growth regulators on the growth and reproduction of the weed annual bluegrass. Previous research suggested that the plant growth regulator prohexadione-calcium hastened senescence of annual bluegrass. Another plant growth...
