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.

Objectives:
Processors need broccoli with better quality traits than what is available in cultivars developed for California and Mexico fresh markets. Farmers need to reduce labor costs of broccoli production but mechanizing harvest. Most contemporary commercially available cultivars are not suitable for either mechanical harvest or processing. The objective of the OSU broccoli breeding program is to develop broccoli varieties adapted to western Oregon with suitable quality and high yields. The program operates on a one year cycle where cuttings from the field are taken into the greenhouse in the fall where they are rooted and hand crossed and self-pollinated to produce seed for the next generation. Seed is harvested in May and June and used to plant trials for fall evaluation.

Objective:
"Sweet corn decline" emerged as a significant constraint to corn production in the Willamette Valley during the 1990's. During the winter of 2001-02 a group of farmers, industry agricultural professionals, and OSU personnel met to discuss strategies for improving our understanding of this syndrome and for identifying strategies for its management.

This publication explores possibilities for new crops in the Columbia Basin. Includes crops for oilseeds, food, forage, revegetation, and xeriscape plant nurseries. Crops are classified into three categories: grasses and cereal grains, broad-leafed herbs and forbs, and shrubs and trees. Includes index by common and scientific names.

The Black Cutworm & Variegated Cutworm can be particularly damaging to corn and bean crops in the Willamette Valley if infestations are not detected early. This page provides some basic information about the pest and discusses management and controls methods. Detailed scouting and monitoring techniques are provided as well as a risk assessment for spray decisions.
Introduction
Beet western yellows virus (BWYV), an aphid-vectored luteovirus, causes a pronounced, bright yellow color to the leaf margin of lettuce, spinach, and other leafy greens. Interveinal chlorosis may also develop. The virus does not usually stunt growth and is not considered a problem in many susceptible crops. However, where the leaves are harvested or comprise the edible portion of the crop, such as with lettuce, spinach, Chinese cabbage, and root crops sold with the shoots attached, even a slight expression of symptoms can render the crop unmarketable.
For the past 18 years, processed vegetable growers in the Willamette Valley, OR have had a vital partner in crop pest monitoring – Oregon State University’s VegNet. This regional pest monitoring program provides weekly activity reports for common broccoli, cauliflower, sweet corn, and snap bean pests. Data is published on www.oregonvegetables.com and is available as an email subscription newsletter. The main goal of the program is to provide an early warning to growers of potential outbreaks that may warrant increased field scouting and action.

Introduction
The cabbage maggot, Delia brassicae, is a chronic pest problem in Willamette Valley cauliflower. This report summarizes the second year of research to identify deficiencies in current practices and improve management of cabbage maggot. This study has investigated cabbage maggot life cycles, evaluated treatment practices and tested sampling techniques for making management decisions.

OBJECTIVES FOR 1996:
To evaluate effects of several winter cover crop systems, including fall-seeded and overseeded triticale, fall-seeded triticale plus winter pea, and overseeded red clover on yield and quality of sweet corn at three rates of N. The cover crops follow broccoli fertilized with three rates of N.
To evaluate the effect of these cover crops and the N applied to sweet corn on the amount of nitrate leached below the root zone.
To evaluate the effect of these cropping systems on the potential for herbicide degredation in the soil profile.

The EPA is making available for a 30-day public comment period a proposed regulatory decision to register Enlist Duo containing glyphosate and the choline salt of 2,4-D for use in controlling weeds in corn and soybeans genetically engineered (GE) to tolerate 2,4-D.

The processed vegetable industry has struggled annually with EPA to secure the Ronilan label. EPA announced that the registration will be cancelled in September 30, 2005. There are a number of new fungicides that have not been evaluated for the control of either Botrytis or Sclerotina for snap beans in Oregon. The currently registered alternative fungicides to Ronilan; Benlate, Bravo, Topsin, and Royal, are all subject to review by the EPA under the guidelines set forth in the provisions of the 1996 Food Quality Protection Act.

The varieties Armado April and Armado Quick (Elsoms, Ltd.) were seeded in 2-inch pots in the greenhouse on August 1, August 16, and August 30, 1978, and were transplanted to the field on August 21, September 12, and September 26, respectively. Plots consisted of two 25-foot rows. Treatments were 1) 50 pounds N/acre as ammonium nitrate applied on December 22, 1978, and again on February 26, 1979, and 2) 100 pounds N on the same dates. Treatments were in randomized block design. Heads were harvested twice weekly from April 13 until May 9, 1979.
Overwintering varieties of cabbage are available, particularly from European seed companies. Variety trials were conducted in 1980 and 1981, with planting dates the same as for the cauliflower, but quality was low and disease incidence high. The hardiest varieties had pointed or conical heads which are not desired in the local markets.
