“When a picture is worth a thousand words!”
A farmer from a neighboring state recently shared this with me after seeing our Wisconsin research on cereal rye for #waterhemp (Amaranthus tuberculatus) suppression:
“Rodrigo, I appreciate the research your team puts out regarding #waterhemp control. I liked seeing the confirmation (of my own observations) from your work last year that cereal rye cover crop can help suppress waterhemp emergence. Attached is a picture from one of my fields last year. One drill section was turned off during the fall rye seeding. Note the difference in waterhemp size/density between where the drill was on and where the drill was off, at post emerge corn spraying time.”
Grower observation at POST corn application timing:
🌱 Cereal rye seeded = smaller, less dense waterhemp
🌱 Cereal rye absent = larger, denser waterhemp
The line in the field says it all. #CoverCrops are not a silver bullet, but cereal rye biomass can be a valuable tool within an integrated weed management program to help suppress waterhemp and reduce weed pressure.
Moments like this make years of applied research and Extension work incredibly rewarding!
