Locations containing the MSU official corn hybrid trials (OHT) were evaluated for foliar diseases during the 2019 season. Curvularia leaf spot and northern corn leaf blight (NCLB) were the two most commonly observed diseases. Presently, the evaluations from the irrigated locations (n=4) are included in the current post.
The EPA implemented new regulations and label updates to emphasize paraquat toxicity and reduce exposure to workers who mix, load, and apply herbicide products containing paraquat.

This publication lists those corn hybrids which have demonstrated superior performance in the Mississippi Corn for Grain Hybrid Trials. No other source tests as many hybrids representing today’s market. Thus, this is a great starting point and barometer for you to judge hybrid performance and select the best corn hybrids for your farm.
Mississippi State goes to great lengths to evaluate, assess and analyze corn hybrid performance. These Hybrid Demonstration trials are grown in numerous on-farm locations throughout the state where you can better evaluate hybrid performance of our region’s most elite hybrids. Grain yield results from this year’s trials are published here.
Although it has been a little warm, winter meeting season is approaching. Certified Crop Advisers can be prepared to get the proper credit for their CEU’s. Do this before the meetings. #mscrops
This will be the last week that southwestern corn borer trap counts will be reported since most corn is past the susceptible stage.
Since June, and most recently over the past few weeks, the corn disease questions have continued to include diseases from the lower canopy, in addition to Curvularia leaf spot. Southern rust was first detected in the MS corn crop on July 5. Since that time a limited number of counties have also observed the disease. However, at present, the amount of southern rust observed has been rather low.
We welcome you to attend the Row Crop Update at the 2019 Mississippi Agricultural Industry Council Annual Convention. This event is hosted at Perdido Beach Resort in Orange Beach, Alabama on Wednesday, July 24 starting at 8:00am.
As the corn crop nears maturity, knowing when you can safely terminate irrigation, without sacrificing yield, or wasting money and labor through unnecessary irrigation is likely the most important decision that will affect your bottom line. In order to make this call, you need to estimate when the crop will reach maturity and how much moisture is present in your soil. This article outlines the steps needed to help make this process accurate and reliable.
Several traps exceeded thresholds for the week ending on July 5. As a reminder, our current thresholds are 50 southwestern corn borer moths within a weeks time for corn that has not yet tasseled. From tassel to dent, the threshold
Southwestern corn borer trap numbers are starting to increase in some areas of the state. Scouting should be intensified over the next couple of weeks. It is likely some fields will reach threshold numbers over the next 10 days to
Most of the corn disease questions over the past week to 10 days have had to do with diseases in the lower canopy. Common rust has been one of the most commonly observed diseases and continues to be observed once plants reach reproductive growth stages.
As the Mississippi corn crop approaches tassel stage, weather has fluctuated from wet to dry conditions during recent weeks. Thus, this may affect your strategy regarding application of various management inputs, including nitrogen fertilizer or other products. This article will discuss factors that will improve your response.
The first week of dry, hot weather has folks scrambling to get ready to irrigate and often creates more anxiety than necessary. Deciding when to start irrigating corn can be confusing, but this article focuses on those factors which will help you make that decision and make more corn.
Vegetative growth stages of corn or sorghum are determined by counting the number of fully emerged leaves with leaf collars present. This methodology can be used to anticipate growth and determine appropriate timing of many management decisions, including herbicide application, sidedress fertilizer, etc….

Mississippi State University will be hosting 2 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology.
Brown stink bugs have been treated on a fair number of acres of corn in the Delta this year. With the loss of Methyl, there are not a lot of good choices to control this pest in corn. We are
Corn productivity may vary considerably depending on what fertilizer source, timing and application method you use. This article discusses how to improve corn response to nitrogen fertilizer and reduce risk of losses.
Over the last couple days we have begin to receive a few calls about brown stink bugs in seedling corn in the Delta region of the state. Stink bugs attack corn by feeding through the side of the stem or
