As you’re planning your final crop protection applications and preparing to scout for disease threats, know what to watch out for and how to spot them.
Corn disease watchlist
Tar Spot – This disease begins showing as a flecking and mild yellowing on the corn leaves before it develops into raised, black, circular fungal structures – often mistaken for tar - that cannot be rubbed off. Tar Spot has quickly spread and grown into a leading disease threat, now appearing in more than 19 states.
Gray leaf spot – You can find gray leaf spot on the lower leaves of your corn in warm and humid environments. These lesions begin as a spot with a halo before elongating into a rectangular lesion running parallel to the veins of the leaf. This causes the leaves to turn gray in color.
Fusarium or Gibberella ear rot – A growing concern for many growers, Gibberella and Fusarium ear rot were two of the leading causes of yield loss in 2023. To spot ear rot, look towards the tip of the ear. Keep an eye out for powdery spores that are blue, green or pink in color, or white mold. Ear rots may appear as these different colors depending on which fungus is causing the rot.
Scouting soybean diseases
Frogeye leaf spot – These spots are recognized by a reddish-brown or purple ring surrounding the spots. As the lesions age, they turn light brown or gray - the centers of the lesions will either fall away or turn white with black specks.
White mold – On your soybeans, white mold will begin as a gray or white lesion at the node before it develops into a white, cotton-like mold. This disease can survive in your soil for many years and kills the plant from the point of infection upwards. White mold was the second biggest yield-robbing soybean disease in 2023, causing almost 30 million lost bushels.
