A plant pathologist is encouraging growers to select varieties with white mold resistance.
Michigan State University’s Marty Chilvers tells Brownfield continuous rainfall this summer after soybean canopy closure caused significant white mold pressure for many farmers.
“If we’re pushing populations, narrow rows, that’s going to increase our risk because we’re increasing that canopy closure,” he says.
His research trials showed resistant varieties were the least impacted.
“Screening commercial varieties, we see about a 20-bushel difference between the most susceptible to the most resistance within a company lineup,” he says.
