Bees Associated with Linden (Tilia spp.) Trees and their Susceptibility to Toxic Sugars in Nectar

Creator:: Argoti, Adriana G.
Abstract:: Bees provide critical pollination services to diverse agricultural crops, native plants and trees. Globally, there are reports of bee declines which have been attributed to diseases, exposure to pesticides and changes in land use that are believed to have led to a reduction in foraging resources and nesting habitats for...

Trinexapac-ethyl timing and rate effects on crimson clover (Trifolium incarnatum L.) seed yield and seed yield components

Creator:: Morad, Mohammed
Abstract:: Oregon is the world’s leading producer of crimson clover (Trifolium incarnatum L.) seed. Recent research has reported that seed yield has been increased in cool-season grass and red clover (T. pratense L.) seed crops with the application of trinexapac-ethyl, a gibberellic acid biosynthesis inhibiting plant growth regulator (PGR) and lodging-control...

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...

Spring nitrogen and cultivar effects on winter canola (Brassica napus L.) production in western Oregon

Creator:: Ferguson, Brock T.
Abstract:: Limited information is available on the effects of applied spring nitrogen (N) and cultivar on winter canola (Brassica napus L.) production in high-rainfall environments. The objectives of this investigation were: (i) to determine the effects of spring N and winter canola cultivars on seed and oil production characteristics, and (ii)...

Mapping quantitative trait loci underlying genome-wide recombination rate and mating system differences in meadowfoam

Creator:: Kishore, Venkata Krishna
Abstract:: Meadowfoam (Limnanthes alba Bentham; Order: Brassicales; Family: Limnanthaceae) is a self-compatible, predominantly allogamous, insect pollinated species. Meadowfoam oil is a source of novel unsaturated very-long-chain (VLC) seed oils (C₂₀ and C₂₂) with low concentrations of saturated fatty acids (typically less than 2%) and outstanding oxidative stability. Here we report the...

Selection for Persistence in Red Clover through Improved Tolerance to Northern Anthracnose [NA; Kabatiella caulivora (Kirch.) Karak.] and Drought

Creator:: Sahin, Muhammet
Abstract:: Twenty-three red clover cultivars and accessions were grown in Boyd, KY, and Philomath, OR to evaluate their tolerance of northern anthracnose [NA; Kabatiella caulivora (Kirch.) Karak.] and drought, dry matter (DM) production, and their agro-morphological characteristics. The key research questions of this study were the influence of NA on yield...

Jointed goatgrass : outcrossing, competition with winter wheat, and response to timing and rate of imazamox

Creator:: Cannon, Joshua B.
Abstract:: Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat (Triticum aestivum L.) production in the United States. Studies were conducted to determine the outcrossing rate, competitive ability, and effectiveness of certain control practices on jointed goatgrass. A field study was conducted over two years at four locations...

Elicitors: A Novel Tool for Controlling the Colorado Potato Beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

Creator:: Butcher, Alexander M.
Abstract:: Over the last several decades, potato production has increased globally as it has been recognized as an important component to improving food security. However, potato production has been continuously challenged by pests. Current pest management practices rely heavily on chemical pesticides. Unfortunately, the overuse of pesticides can be harmful to...
