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.

Five insects contaminate broccoli in the Willamette Valley: cabbage loopers (Trichoplusia ni), cabbage white butterfly larvae (Pieris rapae), diamondback moth (Marrtestra aphids (Brevicoryne brassicae). Broccoli is inspected very closely before it is accepted for processing. Low levels of insect contamination result in the rejection of truckloads of harvested broccoli by processor quality assurance programs and thousands of dollars of loss to growers.

The Cabbage Aphid can cause significant economic loses in broccoli grown in the Willamette Valley (Figure One). The feeding of the aphid on the broccoli plant may reduce yield slightly, but the real damage it causes is contamination. The cabbage aphid contaminates the harvested heads of broccoli. This can result in rejection of entire loads of broccoli by the quality assurance program of broccoli processors. Once the aphids have moved up into the developing broccoli head, it is possible to kill them, but it is no longer possible to remove them as a contaminant.

Rodents are an increasing problem in fields and pastures. Birds of prey play a vital part in integrated pest management of rodent pests. Living on The Land — Attracting Birds of Prey for Rodent Control succinctly describes the value to farmers and ranchers of attracting barn owls and American kestrels for rodent control, and ways to help build up local populations of these birds.

Continued use of atrazine for weed control in sweet corn has led to the evolution of atrazine tolerant weeds. The objective of the research was to evaluate efficacy and crop tolerance of several new herbicides and several herbicide combinations at sites with atrazine tolerant pigweed.

Our goal is to start with computerized record keeping, GPS based sampling systems, and the creation of yield maps. Once this has been done various forms of computer assisted management become possible.

The Cabbage White Butterfly can cause damage to several cole crops in the Willamette Valley. 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
This research has demonstrated that liming clubroot infected soils to a pH ≥7.1 is an effective practice for reducing both the incidence and severity of clubroot. Liming does not kill the pathogen but rather prevents disease spores from infecting the plant. This research demonstrated that highly reactive calcitic lime products could be substituted for hydrated lime as they effectively raise the pH of the soil to the target pH of ≥7.1 within a week after application. The project also demonstrated that boron and Serenade drenches did not suppress clubroot under field conditions.

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 by 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.
