Conditions ripe for crop disease

Conditions are ripe for crop diseases as summer heat intensifies.

University of Minnesota Extension crops educator Angie Peltier says plant pathogens favor a wet start to the growing season.

“Oftentimes for these multi-cyclic diseases, think frogeye leaf spot in soybean, you get lesions forming towards the base of the plant. And those lesions can then produce spores that can infect leaves as they continue to emerge, grow, and develop.”

She tells Brownfield early signs of disease could warrant a fungicide treatment to protect yield.

“Knowing that you have a particular disease now and going forward into the growing season, that’s really critical information for you in order to be able to make a good disease management decision going forward.”

Peltier says her message to growers is scouting is key.
