The EPA has new mitigation requirements for pesticide applicators. Here are tips and step-by-step instructions for how to comply.

The WSU projects that received funding from the Washington Grain Commission in fiscal year 2024 are summarized in the 2023-2024 WSU Wheat and Barley Research Progress Report.

Results of field studies conducted by WSU researchers to help dryland farmers in eastern Washington manage weeds of concerns are now available in the 2023 Weed Control Report.

New Endangered Species Protection Requirements are coming to pesticide labels. This article shares how applicators can comply with the new rules.

A reminder for applicators that paraquat has a closed-system container requirement.

Many conservation goals can benefit both productivity and revenue. Learn more about programs that can offset the cost of trying new conservation practices and explore qualifying conservation practices around nutrient management, IPM, and soil health.

Controlling volunteer wheat is important to minimize the survival of various insects and diseases from one season’s wheat crop to the next.

Growers who want to move away from using Beyond in Clearfield wheat after multiple years of using the technology, may want to consider testing for soil residues before planting a non-Clearfield wheat variety. Use this step-by-step guide to test for herbicide residues by conducting a bioassay.

The Herbicide Resistance Screening Program helps farmers determine if the lack of efficacy of herbicides in their fields is due to herbicide resistance.

Using drones to control unwanted vegetation has many benefits and also requires licensing and planning.

The 2023 WSU Weed Science Field Tour will be held from 1:00 to 5:00 p.m., Wednesday, June 14 at the R.J. Cook Agronomy Farm in Pullman, Washington.

Relying only on glyphosate for Italian ryegrass control in glyphosate-resistant canola is effective; however, this approach is likely to quickly result in the selection of Italian ryegrass biotypes that we can no longer control with glyphosate.

When comparing glyphosate products, it is recommended to look at the amount of “acid equivalent or ae” rather than the amount of “active ingredient” that is listed on the label.

Mustards need to be controlled by late winter or early spring, while they are still in the rosette stage of growth. Fields need to be scouted now, and treated as soon as possible if mustards are located.

If you hold a pesticide or applicators license, you’re likely to have heard the phrase “Label is the LAW” or have been reminded at workshops or presentations to always READ the label before buying the…

The 2022-2023 Research Progress Reports and the 2022 WSU Weed Control Report are now available on the Wheat and Small Grains website.

Oregon Weed Science Society is a non-profit organization founded in 1951 and dedicated to promoting weed science scholarship, education, and knowledge dissemination. Our primary goal is to organize an annual meeting for growers, agronomists, and…

What happened? Wheat fields throughout Eastern Washington are full of downy brome (a.k.a cheatgrass). Many of those that aren’t, are full of Italian ryegrass. Why didn’t herbicides perform better than they did this year?

Wheat harvest is underway in Eastern Washington. With cool spring weather and ample spring rainfall, it looks like it will be a bountiful harvest. Understandably, growers will be focused on getting their grain out of…

The 2022 crop tour season will soon be starting and provides opportunities to view field trials and interact with Washington State University personnel. The list below provides an outline of when each small grain variety…

In the 1990s, when I was beginning my academic career at the University of Nebraska-Lincoln Panhandle Research and Extension Center in Scottsbluff, Monsanto still held the patent for glyphosate, and it could only be purchased…

The 2021 WSU Weed Control Report is now available on the Wheat and Small Grains website. Drew Lyon and Ian Burke, WSU weed scientists, manage numerous field studies to evaluate new herbicides, and new uses…

As the snow begins to fall, memories of the 2021 crop season begin to fade and thoughts about what lies ahead in 2022 start to take center stage. I would like to use this Timely…

First COVID-19 and now DROUGHT-21. We just can’t seem to catch a break. As I drive around the region, I see a lot of green fields, but that green often turns out to be common…

The addition of winter and spring canola to the crop rotations of Eastern Washington has provided growers with increased options for weed control, particularly for some of the most troublesome grass weeds such as downy…
