Tar spot is a fungal leaf disease that infects corn leaves and causes lodging and yield losses. First confirmed in 2015, it has rapidly spread in persistence and reach. Yield losses from tar spot infection can be severe.
Corn and soybean planting season may have been extreme, but there are many benefits to seeding alfalfa this time of year. As alfalfa stands age, yield potential declines.
Downy mildew or crazy top is a condition that often results in wet or flooded fields. A crazy top results when plants are infected by Sclerophthora macrospora at flooding.
Erwinia chrysanthemi pv. zeae is one of the most common causal agent of bacterial stalk rot. It is readily capable of establishing and thriving on corn and sorghum plants as it enters natural openings or wounds made from weather or pests.
Goss’s wilt has rapidly become a significant and yield-reducing disease.
One ear rot taking hold in many fields is Diplodia ear rot. It tends to thrive when there is wet weather and mild during grain fill. Upright ears with tight husks may promote Diplodia development in certain conditions.
Every year, a variety of diseases, fungi, and molds are present on ears as plants near harvest. Correctly identifying what culprits are present may influence your harvest prioritization, grain management and handling, or even next year’s cropping plan.
Late season rains are hard on crop root systems. Standing water can cause suffocation-like conditions where oxygen deprived soil cause death to plant roots and subsequent deterioration of above ground foliage.
