John Goeser, animal nutrition and research director at Rock River, says mycotoxin levels have been a mounting challenge the past few years, but this year is different. He speculates, “We’re seeing challenges due to environmental conditions including heavier rains and humidity throughout silage and corn harvest (September to October), increased fungal disease pressure and reduced tillage or no-till practices.”
Goeser says, “Professor Damon Smith [University of Wisconsin plant pathologist] mentioned to me that his team was seeing fungal contamination as early as June and July this year, which is early.” Goeser also mentioned the possibility of lesser hybrid resistance as a potential cause for increased mycotoxins.
