An agronomist says the widespread tar spot problems in corn had varying impacts on yield.  Scott Rowntree is a field agronomist with Pioneer in Wisconsin. He says, “Anywhere from fairly minimal impact if we were in a field with fairly tolerant hybrids, but fields with susceptible hybrids, some irrigated, where folks might not have used a fungicide on some of these acres, we could easily see 50-100 bushel yield losses in those most susceptible acres.”

Rowntree tells Brownfield many farmers saw infected crops come in with good moisture, but very low test weights.
