Responses and relationships among Fusarium species, sweet corn, and western spotted cucumber beetles

Creator:: Miller, Nathan L. (Nathan Louis)
Abstract:: Sweet corn (Zea mays L.) yields in the Willamette Valley of Oregon have been declining since the early 1990’s. Studies were done to determine if there is a relationship between ear weight and several disease parameters including necrotic crowns or stalk nodes, nodal root rot, radicle root rot, and sub-crown...

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...

Evaluation of fungicides for the control of gray and white mold in snap beans: Report to the Agricultural Research Foundation for the Oregon Processed Vegetable Commission, 2006

Creator:: Ocamb, Cynthia M., McReynolds, Robert B., and Peachey, Ed
Abstract:: Cancellation of the registration of an effective bean mold fungicide, Ronilan, occurred at the end of the 2005 growing season. Finding equivalent alternatives for use in snap bean is critical. The goal of the project is to continue evaluations of alternative fungicides for their effectiveness in controlling white mold (Sclerotinia...
