Numerous plant diseases have been observed over the past several weeks as out corn crop continues to mature. Many of the diseases listed in this post are not problematic once corn reaches milk/dough and are simply presented to aid in the diagnostics at the field level.
Corn kernel set near the ear tip may vary considerably depending on a number of cultural and environmental factors. These kernels have issues when the plant can’t supply enough energy to support all of them. Therefore, if we want to improve our yields, we need to recognize why kernel set is less than desired, so we can improve management in the future.
As our early corn crop nears maturity, knowing when you can safely terminate irrigation or even roll out poly pipe without sacrificing yield, time and money is likely the most important decision that will affect your bottom line. This article outlines the steps needed to help make these decisions accurately and reliable.

Abundant recent rainfall has suspended irrigation needs relative to normal, considering corn is now tasseling across much of the state. Accordingly, corn water demand will be high when soil moisture dries enough for us to make decisions to commence irrigation. This article will address how various factors affect corn irrigation management.
Southwestern corn borers were not detected in any of the trapping locations in any county during the week of May 24th-30th. Southwestern Corn Borer Trapping Program Week Ending May 30, 2026 County Traps Reporting Total Reported Avg/Trap Maximum/Trap Alcorn 3
As the Mississippi corn crop approaches tassel, crop health and weather may greatly affect response to various management inputs, including nitrogen and other practices. The wildcard this year is how dry weather this spring may affect nitrogen relations this season. This article will discuss factors that may affect your strategy and improve your chance for a profitable response.

This is the first southwestern corn borer report of the 2026 growing season. Traps are currently being deployed by extension agents across the major corn-producing counties in Mississippi. Southwestern Corn Borer Trapping Program Week Ending May 16, 2026 County Traps
Corn response to nitrogen fertilizer is a rather complicated puzzle considering all the factors that affect it. Furthermore, you may need to adjust plans depending on if the weather is wet or dry. This article covers a lot of scenarios to improve corn response to nitrogen fertilizer.
This video shows how to identify vegetative growth stages of corn or sorghum in the field. In this case we inspect two different examples of corn that have progressed into rapid growth stages.
Vegetative growth stages of corn are determined by counting the number of fully emerged leaves with leaf collars present. It is important to appreciate this methodology since it is a basis for timing many management practices, including herbicide application, sidedress fertilizer, and others.
Cover crops may improve soil health and water quality and are being grown on more acres. However, their growth extends into the spring and will present challenges for primary crops, depending upon how you handle them. We are researching cover crops, so you can manage them to optimize results for row crop systems.
