Cool weather stalling crop development

A field agronomist for Burrus Seed says the latest cool stretch of weather has caused some corn and soybean emergence issues.

Chris Brown, who covers the eastern two thirds of Illinois and southern half of Wisconsin, tells Brownfield, “We don’t have those growing degree units and that heat out there that really helps those plants power through onto the next phase.”  He says, “It exacerbates some ugliness and you really start to question your stand.”

He says the delayed development can increase the risk of herbicide injury.

“If the crop was stalled out right at that hot layer of herbicide, you might see some increased PPO damage, which normally the crop would just grow through that hot layer.”  He says, “Or you might see some group 15 herbicide damage.”

Brown says patience and warmer weather are the best management options.

“Unless there’s a large stand reduction, you’re probably not going to see a significant yield hit by those.”  He says, “It’s just going to not look appealing.”

While not typically cause for replanting, Brown says growers should continue to evaluate herbicide injured stands to ensure adequate development and populations.
