Science Takes Flight: Detection of Black Leg on Turnip Gray Mold on Hemp

Creator:: Bates, Taylor A.
Abstract:: Disease detection through traditional techniques such as scouting fields on foot, molecular assays, or morphological identification of plant pathogens is time consuming and costly. Disease diagnosis in the field can be extremely subjective, and largely depends on the experience and knowledge of pathogen identification and disease quantification. This thesis provides...

Presence and pathogenicity of Fusarium and Verticillium species in commercial red radish (Raphanus sativus) seed production in the Willamette Valley of Oregon

Creator:: Bomberger, Rachel A.
Abstract:: Commercial radish seed producers in the Willamette Valley of Oregon have observed a late season wilt in their seed fields. Twenty-two fields were surveyed for wilt in the Willamette Valley during June through August 2012 and 2013. Plants exhibiting wilt symptoms were collected from the fields and examined for vascular...

Hop cone tip blight : a new disease in the Pacific Northwest

Creator:: Bienapfl, John C.
Abstract:: A necrosis at the tip of cones was observed on hop (Humulus lupulus), cultivar "Nugget", grown in Oregon in the early 1990's. Fusarium sambucinum and F. avenaceum were recovered from symptomatic cones in 1998 and preliminary inoculation experiments suggested both Fusarium species could cause hop cone necrosis. Studies were carried...

Examinations of Fusarium sambucinum on Humulus lupulus and co-infection with hop stunt viroid in commercial hop fields

Creator:: Cerruti, Natasha R.
Abstract:: After an unusually high incidence of Fusarium canker was observed in commercial hop fields of the Pacific Northwest, field surveys were conducted and revealed that canker incidence ranged from 20 to 60% of bines sampled in six commercial fields, as well as wide-spread Hop stunt viroid infection in these six...

A shoreline survey of on-site systems in the Tillamook Bay Watershed, Tillamook County, Oregon

Creator:: Gaines, Cynthia K.
Abstract:: Tillamook Bay is used for recreational activities such as swimming and diving, as well as recreational clam harvesting. The bay is also used for one of Tillamook's most prominent industries, oyster harvesting. Bacterial contamination of Tillamook Bay has been a recognized problem since 1962. There are a number of known...

Pollution prevention in Oregon's electronics industry

Creator:: Jones, Cynthia L.
Abstract:: Pollution prevention is promoted by the Environmental Protection Agency (EPA) and other governmental agencies as a method of reducing the generation of wastes and pollutants. Pollution prevention is also called source reduction because it reduces wastes early in the production process. Source reduction has been used by some industries to...

Investigations of Black Leg and Light Leaf Spot on Brassicaceae Hosts in Oregon

Creator:: Claassen, Briana J.
Abstract:: The Pacific Northwest is an internationally important region for the production of Brassica seed and other seed crops including grass seed. Oregon lawmakers mandated research into the co-existence of canola (Brassica napus) with other Brassica production in the Willamette Valley and House Bill 2427 was signed into law in 2013,...

Addressing the relationship between Pseudoperonospora cubensis and P. humuli using phylogenetic analyses and host specificity assays

Creator:: Mitchell, Melanie N.
Abstract:: The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...

Competing Roles of Sea Level Rise and Sediment Supply on Sediment Accretion and Carbon Burial in Tidal Wetlands; Northern Oregon, USA

Creator:: Peck, Erin K.
Abstract:: Quantification of contemporary sediment and carbon accumulation within Oregon tidal saline wetlands will: (1) fill a critical knowledge gap, and (2) naturally test without complicating variables whether sea level rise or sediment supply primarily control wetland growth. Here we measure vertical accretion rates and carbon burial rates in three Oregon...

Heuristic algorithm for multistage scheduling in food processing industry

Creator:: Juwono, Cynthia P.
Abstract:: A multistage production system consists of a number of production stages that are interrelated, that is the output from one stage forms input to the next stage. There are constraints associated with each stage as well as constraints imposed by the overall system. Besides, there are multiple objectives that need...
