Saline County Wheat Crop Enters Harvest Under Pressure From Disease and Unsettled Weather
Saline County wheat producers are entering the 2026 harvest season with concerns about disease-related yield losses, drought damage and recent storms that have delayed cutting across portions of Kansas.
Harvest activity has begun moving into central Kansas, although verified yield, protein and test-weight reports specifically from Saline County have not yet been released.
The U.S. Department of Agriculture reported that 6 percent of the wheat in Kansas’ central crop-reporting district had been harvested as of June 7. Statewide, harvest was 5 percent complete, compared with the five-year average of 1 percent for this point in the season.
The crop matured considerably earlier than normal. Across Kansas, 62 percent of winter wheat was mature, compared with 11 percent at the same time last year and a five-year average of 16 percent.
Despite the early development, the condition of the crop remains poor. USDA rated 26 percent of Kansas winter wheat in very poor condition and another 31 percent in poor condition. Only 14 percent was rated good, and none was rated excellent.
In Saline County, wheat streak mosaic virus could become one of the largest causes of lost production this year.
Gypsum-area farmer Justin Knopf told Kansas Wheat that 2026 is the worst year he has seen for the virus’s effect in the area. Numerous fields have shown a high presence of the disease, while fields located near an infection source have experienced more substantial damage.
The virus can prevent wheat from heading properly and reduce grain development, particularly when the plant’s upper leaves turn yellow before grain filling is complete. There is no treatment capable of reversing an infection once it is established.
Knopf said wheat streak mosaic virus was likely to become the leading cause of yield loss in the area unless another major weather event, such as hail or excessive heat, caused greater damage.
The outbreak has been linked to several factors, including consecutive dry fall and winter seasons, hail-damaged fields and volunteer wheat or other plants that allowed wheat curl mites to survive between growing seasons. The mites spread wheat streak mosaic virus as they move into newly planted fields.
Recent rainfall has added another complication as harvest begins.
Storms and persistent humidity have kept combines out of fields in parts of central and eastern Kansas. Farmers elsewhere in the state have reported that wheat went without needed rain during important growing periods, only to receive rainfall as the crop became ready to harvest.
Early Kansas harvest reports have shown wide differences in production. Farmers in nearby areas have reported yields ranging from fewer than 10 bushels per acre in severely damaged fields to more than 40 bushels per acre in stronger fields.
Those reports should not be treated as Saline County results. Local yields, test weights and protein levels will become clearer as more combines enter fields and grain begins arriving at area elevators.
For Saline County producers, the final outcome will depend on how severely individual fields were affected by drought and disease, along with whether dry weather allows the crop to be harvested before additional quality losses occur.
