Tar spot has already been discovered in corn crops in Nebraska.
Fourteen counties have reported detecting the disease so far this year. Agronomists say that its presence at this point in the growing season is not surprising.
It has also been found in neighboring states, including Iowa, Kansas, Missouri, and Indiana.
Nebraska Extension advises farmers to intensify scouting efforts in fields with a history of disease or those in higher risk, like pivot irrigation fields.
Fungicide use is not recommended at this time because research shows application for tar spot management is most effective between R2 and R3 growth stages.
Large rain events, like those recently in Nebraska, can create ideal conditions for tar spot and other diseases to take place, so scouting is essential.
The USDA’s upcoming reports will drop on Tuesday afternoon, giving the trade real results on acreage shifts, drought concerns, and ongoing trade tensions, adding uncertainty for U.S. farmers.
