Many growers in the Mid-South apply a herbicide shortly prior to sorghum harvest to facilitate combine efficiency and suitable grain moisture. This season, this issue is even more critically important because of severe harvest problems potentially created by White Sugarcane aphid infestation. This article will discuss appropriate timing and potential outcome of such harvest aid applications.
Southern corn rust continues to be observed throughout MS. We continue to receive calls regarding late fungicide applications (> R4/R5) to reduce yield losses attributed to southern rust. Numerous myths regarding the disease have been widely spread throughout the MS corn production area including death of a corn plant in as fast as 7 days following southern rust infection and lodging as a result of heavy southern rust infection.
The North Mississippi Research and Extension Center’s Agronomic Row Crops Field Day on Thursday, August 7 will present the latest research to the area’s row-crop farmers and consultants. The field day will be from 8 a.m. to 1:30 p.m. at the Lee County Agri-Center Magnolia Conference Center on Highway 145 South in Verona.
“It ain’t over till it’s over!” Amazing as it seems, several producers have not laid poly pipe. After the five plus inches of rainfall we received last week, some producers are questioning the need to lay pipe this late in
Considering the abundant rainfall during June and the corn crop progressing closer toward maturity, many are wondering whether additional irrigation may even be needed. This article discusses how to make that and other late-season irrigation decisions.
Foliar corn diseases continue to be observed throughout the MS corn crop. Common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight are all present at low levels throughout the Delta. As of Wednesday (June 25, 2014), southern corn rust had only been observed in southeastern MS (Forrest, George, Greene, Jackson, Perry, and Stone counties).
The importance of soil moisture sensors is becoming more evident as we continue forward this growing season. Today (Monday, June 16th), we received a call regarding sensor readings that were assessed early this morning. The following are the data discussed in this scenario.
More and more corn growers are applying various management inputs around tassel stage in order to improve efficiency and corn productivity. This article discusses how crop physiology affects the appropriate timing and crop response.
A corn, cotton, peanut, and soybean field day is scheduled for June 17th at the Delta Research and Extension Center in Stoneville, MS. The general theme of the field day will include pertinent information for mid-season row crop issues.
Considering the abundant rainfall we experienced during April and typically have, it is usually very important to optimize nitrogen fertilizer management. This newsletter discusses best management practices for corn nitrogen fertilization. These recommendations reduce the risk of nitrogen loss and can improve crop response when wet weather is prevalent during the spring.
Mississippi growers will likely plant far more acres to grain sorghum than previous years. This article outlines suggested seeding rates and other key planting tips for successful sorghum production.
Much like last year, as rains delay corn planting progress, more concerns arise regarding the appropriate “cut-off” date for planting corn. This article states new guidelines for late corn plantings based upon recent MSU research.
March is here, anticipation is building and our fields may dry out soon, if rain holds off. So when should we start planting corn? This article gives tangible recommendations for determining suitable planting time when nature throws us curveballs.
Included are Mississippi State’s suggested grain sorghum hybrids for planting during the 2014 season. These hybrid recommendations are intended for dryland production.
Mississippi has a 24c label allowing Avipel use on field or sweet corn seed for the purpose of repelling blackbirds and cowbirds. Thus, we no longer need to rely on an emergency condition to be declared. This newsletter will discuss different formulations and use of this product on corn seed.
RISER irrigation approach reduces water use by 50% while maintaining yield potential.
The MSU Corn Hybrid Demonstration Program evaluates superior corn hybrids from numerous seed companies who participate in the MSU Corn for Grain Hybrid Trials. Our objective is to provide you more opportunity to evaluate premier corn hybrids and substantially supplement the information gathered in the University Hybrid Trials.
On February 6th 2014, Mississippi State University will host the second annual “Future of Agriculture Graduate Student Competitionâ€. The competition will be open to M.S. and Ph.D. students working in production agriculture.
This effort lists those corn hybrids which have demonstrated superior productivity in the MSU Corn for Grain Hybrid Trials. Approximately 80 corn hybrids representing the vast majority of seed companies in the Mid-south participate in the MSU hybrid trials. This information should help you better assess relative corn hybrid productivity and profitability in future seasons for either irrigated or dryland culture.
Italian ryegrass is a serious weed in wheat production and continues to spread across much of Mississippi. The increasing prevalence of Italian ryegrass in grower fields is compounded by the lack of control from many commonly used herbicides, such as ALS inhibitors and glyphosate.
Metribuzin is an important herbicide for controlling numerous weed species in wheat. However, wheat varieties may differ in tolerance to metribuzin. This article shows our evaluations of wheat varieties included in the current MSU Wheat Variety Trials for metribuzin tolerance. This should help you better assess potential for wheat crop injury.
This publication lists those wheat varieties which have demonstrated superior productivity in the MSU Wheat and Oat Variety Trials and summarizes their characteristics. This impartial information should help you better assess wheat varieties and pick those suited for your farm this season.
Numerous questions have come in over the past few weeks regarding proper grain storage. Maintaining moisture below 15% is extremely important to reduce the likelihood of fungal growth. However, not all fungi that develop on harvested grain are problematic and toxin production is not something that can occur overnight. Even though fungi such as Aspergillus flavus can produce a green fungal growth on harvested grain not all fungi that grow on grain can be considered to be A. flavus.
Corn fungicide questions continue to be made even in situations where corn has reached dent. In general, making a fungicide application at dent or later corn growth stages only pays off if excessive disease pressure is observed prior to the fungicide application being made. Moreover, making a fungicide application to a foliar disease tolerant hybrid will likely not pay off since the genes present in the hybrid should be relied on for preventing yield loss as a result of foliar disease.
This season’s corn crop is generally much later than normal and far behind the pace of last year’s crop. Thus, even the earliest fields will need additional irrigation or rainfall for several more weeks. This article discusses crop progress and methods to schedule and terminate irrigation water for corn.
