Kyle Strachila is a crop protection field sales representative for Bayer Crop Sciences. He says customers are proactively looking to Prosaro® fungicide, one of their products to manage this disease. Strachila… “I've heard of guys in the last couple of years, starting to use Prosaro® as their preventative measures on almost every irrigated acre that they advise for, because the Fusarium disease is really prevalent in fields after a corn crop.
