DISEASE OBSERVATIONS

Reports of mosaic virus symptoms have increased this past week, with moderate levels reported in symptomatic fields. All of the samples we have tested so far this year have been positive for both Wheat streak mosaic virus (WSMV) and Triticum mosaic virus (TriMV) (Figure 1). In WSMV-resistant varieties, WSMV levels have been low, so the symptoms observed in these varieties are very likely caused primarily by TriMV. However, in susceptible varieties, both WSMV and TriMV levels have been very high. This suggests that the WSMV resistance is still working in WSMV-resistant PlainsGold® varieties, but we will continue to monitor for resistance-breaking. The drought has contributed to the severe virus disease symptoms this year.

Premium Program

2026 program Information:

Ardent Mills has partnered with the Colorado Wheat Research Foundation (CWRF) and CSU for years to develop top performing wheat varieties that meet the special quality needed for UltraGrain®.

Eligible Plainsgold Varieties:

PlainsGold Hard White Winter wheat varieties are developed at Colorado State University (CSU) specifically for the quality characteristics needed by Ardent Mills, with the yield performance and agronomics needed by farmers.

For the 2027 crop year, the following varieties are included in the program: Snowmass 2.0, Breck, Monarch, Windom SF, and Telluride. Certified seed is required on all Ardent Mills contracts, and the use of glyphosate for pre-harvest crop desiccation is prohibited.

Ardent Mills is currently paying premiums as follows for the 2027 crop. Future year contracts are subject to market conditions and may change. For 2027, all varieties are paid at the same premium levels:

  • $0.25 base grower premium
  • $0.40 @ 11.0% protein
  • $0.60 @ 12.0% protein
  • + $0.05 each half a point up to 14% ($0.65 at 12.5%, $0.80 at 14%)

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.
