Weed management is a continual challenge to Oregon table beet growers. Research over the last several years has documented that s-metolachlor (Dual Magnum) will substantially improve weed control and crop yields when applied alone or in concert with other registered herbicides such as Roneet and Pyramin, with the potential to...
The objective of the study was to 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 looses effectiveness if rainfall is excessive after application.
1) Develop and moderate a workshop to discuss hypothetical crop rotation strategies that would
allow conversion of land to organic processed vegetable production without exacerbating weed
or pest positions.
• Invite industry leaders to help develop crop rotations
• Invite potential forage consumers/buyers to help focus on projected forage needs...
The objectives of this project were to evaluate the efficacy of common row crop herbicides for control of puncturevine, and determine the effect of post harvest weed management strategies on hairy nightshade seed development.
Research efforts were focused on testing various inbred combinations for hybrid produc-tion, and evaluating commercial cultivars for adaptation to Oregon growing conditions and for head rot resistance.
SUMMARY
• Impact and Laudis herbicides were evaluated for wild proso millet and broadleaf weed
control in sweet corn.
• The most effective treatments were Impact and Laudis applied with Outlook and atrazine at
V2-3.
• Increasing the methylated seed oil (MSO) rate from 0.25% to 1 % was more...
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...
Objective 1: Evaluation of commercial sweet corn varieties and inbred germplasm in small plots for susceptibility to seed rot/damping-off as well as root, stalk, and crown rot. Objective 2: Evaluation of microbial (biofungicides) and chemical treatments for suppression of sweet corn seed rot/damping-off, root rot, and crown rot.Objective 3: Cooperate...
