Pesticide Labels Are Changing
The Environmental Protection Agency (EPA) regulates pesticides because their use can affect animals and plants (or their habitat). Farmers and applicators should expect to see some new application requirements on their pesticide labels to comply with the EPA Endangered Species Act.
- What You Need to Know About Pesticides and the Endangered Species Act
- New rules for herbicide applications are coming, are you prepared?

Tools & Calculators
Several tools and calculators have been temporarily removed to be redesigned for better accessibility and ease of use. If you don’t see the tool you’re looking for below, we have a few tools available as raw file downloads in our archive. Please subscribe to the “Smallgrains” listserv to be notified when more tools become available.
Variety Selection Tool
A preliminary edition of the Variety Selection Tool is available, although it does not contain all varieties and data yet.
This interactive tool helps wheat growers select what variety of crops to grow based on rainfall zone.

Spring Canola Nitrogen
Use this calculator to determine how much nitrogen fertilizer your dryland spring canola crop needs.
Dryland Wheat Nitrogen Recommendation
Nitrogen recommendations are based on the potential yield for a site, the amount of N required to achieve yield and protein goals for a desired wheat class, and an inventory of soil N contributions.
Growing Degree Day Calculator
Estimate growing degree days based on detailed weather information from AgWeatherNet.
WSU Pesticide Information Center OnLine (PICOL) Database
Search for electronic copies (PDFs) of information from pesticide products registered in Oregon, Washington, or both.
AWN Spray Guidance Tool
Identify the most favorable times to spray for crop protection and weed management, while reducing chemical drift and human exposure. Once signed in, navigate to Models >> Human >> Spray Guidance.
Post-Harvest Hard Wheat Performance Evaluation
A post-harvest assessment of grain yield, protein and test weight by field or zone within the field can help you evaluate what went wrong (or right) during the crop year and inform your plans for next year.
Postharvest Wheat Nitrogen Efficiency
Average yield per acre and grain protein concentration can be used to estimate N uptake by the crop. These measures of N efficiency can be used to refine future N management practices.
