American Farm Bureau Federation President Zippy Duvall is calling on President Trump to take steps to lower diesel prices as farmers face record-high fuel costs during harvest. In a letter to the president, Duvall asked for a temporary suspension of the federal highway diesel tax, which currently exceeds 24 cents per gallon. He says diesel is essential for running tractors, combines, and irrigation equipment, as well as transporting crops, livestock, and farm inputs. The national average on-highway diesel price has reached $6.38 per gallon, while farm diesel in the heart of the Corn Belt is approaching $6. Farm Bureau is also asking the administration to waive federal penalties for emergency use of dyed diesel on highways. Duvall says farmers cannot postpone harvest or simply stop using diesel when prices rise, making high fuel costs a significant challenge during one of the busiest times of year.
