Wheat Stem Sawfly
We have continued our sweeps twice per week at Orchard and New Raymer, CO. This month’s average catch has deviated significantly from what we observed throughout the month of May in previous years. For example, on May 17th, 2022, our average catch was 72.6 sawflies per sample site. In contrast to this, on May 26th of the current year we averaged only 29.4 sawflies per sample site.
The 2023 sawflies in these areas are emerging later than those of previous years. As explained in our May 1st newsletter, we’re hypothesizing that an increase in precipitation has delayed the sawfly emergence cycle. We’re expecting to observe sawfly activity well into June. This may not be the case for regions that have received less moisture.
Sally Jones Diamond (CSU Crops Testing) has visually confirmed sawfly adults at the variety trials in Akron and Yuma, CO. The activity appears to be particularly heavy at Akron. Our sawfly emergence graphs from 2011-2022 can be viewed at Research

Wheat Assessment

Wheat Subject to Assessment

Wheat grown in the 32 Colorado counties covered by the Colorado Wheat Marketing Order are subject to assessment. The counties include: Adams, Arapahoe, Baca, Bent, Boulder, Cheyenne, Crowley, Custer, Douglas, El Paso, Elbert, Fremont, Huerfano, Jefferson, Kiowa, Kit Carson, Larimer, Las Animas, Lincoln, Logan, Moffat, Morgan, Otero, Phillips, Prowers, Pueblo, Rio Blanco, Routt, Sedgwick, Washington, Weld, and Yuma.

Assessment Rate

The current assessment rate is two cents per bushel.

Refundable Assessment

A producer may request a refund of that portion of the assessment withheld which exceeds one-half cent per bushel (currently one and one-half cents per bushel).

Producers can request an “Application for Refund of Wheat Assessment” (ARWA) form by contacting the Colorado Wheat Administrative Committee (CWAC) by one of 2 ways:

Mailing a written request to

4026 South Timberline Road, Suite 100
Fort Collins, CO 80525

E-mailing a written request to

info@coloradowheat.org

Producers must submit a completed ARWA form, along with proof of assessment withheld, within 30 days of the date of assessment to be eligible for refund. The date of assessment is the actual date of wheat sale or date wheat was placed under loan by the FSA.

Assessment Collection & Remittance

Wheat assessment is collected by the “first handler” (typically an elevator or feedlot) directly from the producer and then remitted to the Colorado Wheat Administrative Committee (CWAC). A “Wheat Assessment Reporting Form” and full instructions can be obtained from CWAC.
