One new U.S. state was added to the list of states reporting fumonisin in corn, according to Neogen’s Monday Mycotoxin report from November 16.

Meanwhile, the U.S. corn harvest is advancing, with 93 percent of the harvest completed. That is 15 points ahead of this time last year and 5 points ahead of the five-year average.

Mostly favorable weather across the country has helped harvest progress. In the past week, temperatures east of the Mississippi River averaged 6 degrees above normal, while temperatures in the west were slightly below normal. Precipitation was near normal, although heavy rains fell in the Mississippi Delta and parts of the Southeast.

Texas and Colorado are the only states that remain behind average harvest progress for this time.
