Diesel fuel prices continue to decline, with off-road prices in some California locations at $1.89 a gallon, according to the Sacramento-based California Farm Bureau Federation.
Off-road diesel contains red dye, so it can be distinguished from retail diesel. Off-road diesel, which is used by agriculture and construction, also is not taxed.
The California Energy Commission says diesel prices got as high as $5.77 per gallon as demand from Chile took diesel supplies from California and all over the United States.
Chile experienced a colder-than-average winter and needed diesel to power electric generators to keep houses warm. That caused California diesel prices to soar higher than gasoline.
The lower prices come as farmers in California's desert regions have planted winter vegetable crops.
