Clubroot is becoming an increasing problem on Willamette Valley vegetable farms. Most cultivated brassica crops (broccoli, cauliflower, cabbage, etc.) are highly susceptible to the disease, which is caused by the soilborne fungus Plasmodiophora brassicae. In severe cases it can cause significant crop losses, and heavily infested fields may be taken out of production. Once a field is infected, eliminating the pathogen is difficult if not impossible because its thick walled resting spores have been shown to remain viable in soil for up to 18 years. As a result, once pathogen populations have developed to economically damaging levels, the goal of the farmer is to manage rather than eradicate the disease. One effective control strategy is to raise the soil pH to ≥7.2 through liming.

Objective:

  1. compare crop tolerance of carrots and parsnips to two soil and early postemergent herbicides. Dual Magnum (s-metolachlor) was recently registered for use on root crops, but provides poor control of hairy nightshade, and loses effectiveness if rainfall is excessive after application.

Introduction

Control of virus-vectoring aphids is essential in potato seed production to exclude viruses such as potato virus Y (PVY) and leaf roll. Floating row covers might protect plants from insect attack, reducing the need for insecticides.

Research report from OSU's North Willamette Agricultural Research and Extension Center

Shallots can be planted in October for harvest the following summer. A major problem in overwinter shallot culture is weed control. Winter rains make tractor cultivation or hand-hoeing nearly impossible and effective herbicides have not been available. These trials were designed to test the weed control effectiveness of four herbicides applied immediately after planting and their effect on crop fields.
