News and Events

Ag Tech Field Day is a new event for 2025! Hosted at OSU's North Willamette Research and Extension Center in Aurora, OR, the event will showcase research trials, demonstrations, and discussions about emerging technology applications for farms in our region. Join us on June 12th, 2025. The link provides details on presenters and topics and the station locations can be seen on this map. 

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.

Introduction

Aphid and Looper Contamination of Broccoli and Cauliflower (2002)
December 31, 2002

Report to the Oregon Processed Vegetable Commission

Dan McGrath
OSU Dept of Horticulture

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.

Attracting Birds of Prey for Rodent Control (2012)
December 1, 2012

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.

Cabbage Aphid & Green Peach Aphid

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.
