Recently, we hosted a Willamette Valley Vegetable Education Day at NWREC. The link includes slides from our presenters on a variety of topics including pest management, irrigation, and cover crop selection.
For more field days and workshops, check out the NWREC Events calendar and the College of Agricultural Sciences Field Days calendar.
Extremely high quality leeks are being produced on a small scale in the Willamette Valley with good yields. The crop is usually seeded in early spring, matures in autumn, and can be held through the winter for harvest the following spring. Very few varieties are grown commercially and the highest quality plants have been transplanted and grown in trench culture. The most lucrative market is the restaurant trade, which demands long, thick, blanched stems. Healthy foliage can also be used decoratively in presentation of restaurant dishes.
Control of virus-vectoring insects, particularly aphids, is essential in production of potatoes for seed to exclude viruses such as potato virus Y, leaf roll, and net necrosis. Seed production fields are heavily treated with insecticides to prevent virus transmission, but control is often inadequate. Floating row covers may protect plants from attack by insect vectors, reducing the need for insecticides. Row covers might also increase yield through their effect on air and soil temperatures around the plants.
Objective: Identify sweet corn hybrids released for the processing market for high and stable yields under heavy and light root rot pressure.
VegNet is a regional pest monitoring and reporting network serving the Oregon processed vegetable industry, managed by the OSU Extension Service, and funded by the Oregon Processed Vegetable Commission. In the early spring of 2007, a variety of insect traps were placed on cooperating farms in vegetable production areas around the Willamette Basin and maintained during the growing season.
Three trials at two locations were conducted to evaluate sweet corn hybrids for performance under root rot conditions. While both sugar/se and supersweet sweet corn hybrids were evaluated, the emphasis was again on identifying supersweet hybrids with improved tolerance to root rot.
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 sclerotiorum) and gray mold (Botrytis cinerea) on snap bean.
Objective 1: Evaluation commercial sweet corn varieties in small plots for susceptibility to seed rot/damping-off as well as crown rot.
Cancellation of the registration of an effective bean mold fungicide, Ronilan, is slated to occur at the end of growing season in 2005. Finding equivalent alternatives by 2006 for use in snap bean is critical. The goal of the project is to continue evaluations of alternative fungicides for their effectiveness in controlling Gray Mold (Botrytis cinerea) and White Mold (Sclerotinia sclerotiorum) on snap bean using Ronilan as the industry standard.
Twenty-five sweet corn cultivars were evaluated for resistance to natural infection by common smut.
Fifty-three preliminary OSU breeding lines along with Savannah, 91G, OR54, OSU 5630, and OSU 5669 as checks were processed in the 2009 OSU Preliminary Breeding Trial. In the Commercial Trial, seventeen commercial selections were processed along with four checks:. OR 91G, OR 54, OSU 5630, and OSU 6443.
Objective 1: Evaluate sweet corn inbred germplasm for colonization of silks by Fusarium species and subsequent seed infection/contamination. Objective 2: Evaluate biological applications to silks and subsequent Fusarium presence in ears. Objective 3: Evaluate seed disinfestation and location of remaining Fusarium on or in seed. Objective 4: Examine the yield and disease levels of sweet corn plants grown from seeds treated with germicidal light.
Objective: Identify sweet corn hybrids released for the processing market for high and stable yields under heavy and light root rot pressure.
