The winter wheat/summer fallow rotation is the most common cropping system in eastern Oregon. It is used to store winter precipitation and control weeds.

Weed control in grass pastures is limited to controlling broadleaf weeds and is generally accomplished with postemergence, translocated herbicides.

The wheat herbicides that are available for control of grasses include Axial, Maverick, Osprey, PowerFlex and Prowl H2O, are they are most effective when applied in the fall. Some of these products can work in the spring, but to be effective the weeds must be small, or in the case of Prowl, it must be applied before weeds germinate.
These herbicides have the longest application window. They can all be applied to winter wheat up to the boot stage (Feeke’s stage 9). However, many of these herbicides have fairly narrow spectrums of weed control.

Herbicides for Annual Weed Control in Eastern Oregon Wheat More than 50 different kinds of broad- leaf weeds and grasses can be found in most eastern Oregon cereal fields.

This handbook is designed as a quick and ready reference for weed control practices and herbicides used in various cropping systems or sites in Idaho, Oregon, and Washington. This handbook will be useful to Extension agents, company field representatives, commercial spray applicators and consultants, herbicide dealers, teachers, and producers.
Weed control in winter wheat requires an integrated system that relies on numerous management decisions related to maximizing crop growth and minimizing weed growth. The use of multiple cultural practices for weed control frequently provides synergistic benefits greater than the added effects of using just one or two cultural practices.

Weed management in the turf industry is very costly. It has been estimated that $ million per year is spent on invasive weed control in residential turf and $ 1 billion per year in the golf course industry.
When evaluated 30 days after treatment, control of rattail fescue was inadequate at rates typically used for control of downy brome and volunteer wheat (16 to 20 oz/A of Roundup Original®). A high degree of weed control (> 95%) is necessary to prevent rattail fescue seed production in chemical fallow.
In eastern Oregon, feral rye populations of 18 plants per ter annual grass weed that reduces wheat yield, grain quality and grade. Control methods are discussed in this NebGuide.
Some growers use herbicides early to control weeds and retain crop residues and then switch to tillage later to prepare the.

herbicides in western Oregon wheat production. Continued reliance on Hoe lon for grass control in winter wheat without sound crop rotation and herbi-cide rotation practices is not good management. When possible, all herbicides should be managed to prevent or delay weed shifts and the development of resistance.
Fall herbicide applications may not control late fall- or early spring-germinating winter or summer annual weeds. An early spring treatment after summer annuals emerge may be more effective. As the crop comes out of dormancy, apply herbicide with a top-dress fertilizer for minimal wheat stand impact.
“Weed-and-feed applications give the wheat. Strengths - Annual ryegrass, downy brome, some annual broadleaves; Wheat or triticale must be planted –1 inch deep to avoid crop injury.
Must be applied before weed emergence. Any emerged weeds will not be controlled, so use a tank mixture to control them. For best results, apply Prowl H2O once the wheat rows are visible and before weeds. Weed Control Recommendations in Wheat 9 Table 3.
