Ronnie Schnell, Ph.D. Associate Professor and Cropping Systems Specialist Texas A&M AgriLife Extension, College Station   Tony Provin, Ph.D. Professor and Extension Specialist – Soil Chemistry Texas A&M AgriLife Extension, College Station   Numerous rain events have resulted in flooding or significant ponding of water in many corn and sorghum fields across Texas.

Northern Corn Leaf Blight

As was the case in the spring of 2020, the fungal disease of corn, northern corn leaf blight (NCLB) (Figure 1), is again a concern in the spring of 2021. In most years in south and central Texas, a few lesions of the disease are seen on the lowest leaves and the disease never progresses. Disease development is driven by frequent rain and temperatures lower than 80°F. In a typical Texas growing season, infrequent rain, but moreover, increasing temperatures will hinder the progression of the disease. Cool, rainy… Read More →
