Holcus leaf spot, a leaf spot of corn caused by a bacterium, has been confirmed across a wide geographic area in the Mississippi Delta over the past two weeks. The disease is typically characterized by numerous cream to white lesions on the corn leaf that can oftentimes be confused with herbicide (paraquat) drift.
The 2012 Mississippi Agricultural Industry Council and Mississippi Seedsmen’s Association convention will be held again at beautiful Perdido Beach Resort in Orange Beach, Alabama, on July 24-July 28, 2012. This will be our 19th year at Perdido Beach Resort.
In addition to the wheat rusts we’ve been observing over the past few months throughout our wheat production area, numerous additional foliar disease have been observed. The abnormally warm temperature and heavy dews we’ve experienced over the past several weeks have allowed several other wheat diseases to occur.
Sentinel plots will continue to be used to monitor for yield-limiting diseases throughout MS during the 2012 season. Even though in the past sentinel plots have more typically been used to monitor for the presence of soybean rust, the plots will be used to monitor for all economically important soybean diseases.
Heavy leaf and stripe rust sporulation continues to be a concern throughout much of the wheat production area in MS.
I have been told in many places by many people that using poultry litter to fertilize crops spreads weed seeds. However, research by Auburn, the universities of Kentucky and Georgia, and most recently, Virginia Tech found this to be untrue.
Wheat diseases continue to be identified throughout the MS production area. Barley yellow dwarf virus, leaf rust, powdery mildew, and stripe rust are all present in limited situations in several counties.
Paraquat is a critical component of an at-planting herbicide application.
The severity of the glyphosate-resistant (GR) Italian ryegrass problem in Mississippi has varied from year to year. This year has been the worst year since the initial confirmation in 2005, and GR Italian ryegrass is spreading.
In the last couple of days there have been calls coming in about armyworms in wheat. It is not unusual for us to get armyworms in wheat in MS but this at least 2-3 weeks ahead of schedule compared to years past.
The time until cotton starts to square is still a few months away, but it is not too early to start thinking about managing plant bugs in cotton. With the mild winter, plant bug population densities appear to be a little higher on wild hosts than they have the past couple of years.
Variety selection is one of the most critical components in maximizing soybean yields. Soil type, planting date, maturity group, and many other factors are key components in selecting the correct variety for your farm. The Mississippi Soybean Promotion Board offers a tool to aid you in your selection.
Corn is quite unique because much of its potential productivity is determined during the planting process. Thus, corn is often much more responsive or dependent on variables implemented during planting than other Southern crops. This article gives planting guidelines for enhancing corn productivity.
We are pleased to announce the EPA has granted the Mississippi Department of Agriculture a Section 18 emergency exemption allowing the use of anthraquinone, which is an unregistered product marketed as Avipel on field or sweet corn seed for the purpose of repelling blackbirds and cowbirds in newly planted corn fields in the state of Mississippi.
MSU Extension Service Publication 2647, Nutrient Management Guidelines for Agronomic Crops Grown in Mississippi, is now available. It includes: ********************************** Introduction to Nutrient Management The Soils of Mississippi Plant Nutrients Introduction to Soil Testing Introduction to Inorganic Fertilizers Lime, Liming
Over the past two weeks the reports of both stripe and leaf rust of wheat have increased in MS. The following blog article provides information regarding the developing situation. The continued unseasonably warm environmental conditions may contribute to an increase in stripe rust severity this season.
Word on the street is there will be many more corn refuge checks in 2012 in cotton growing regions. This is due to decreasing compliance over the last couple of years. However, it is getting so complicated that one grower
For many years, one of the mainstay residual herbicides in soybean weed control systems was metribuzin (Sencor/Lexone). One of the drawbacks to metribuzin use is the sensitivity of some soybean varieties to this herbicide. A research project conducted by Mississippi State University and the University of Arkansas screened some of the modern germplasms available to producers for metribuzin tolerance.
A disease issue and the response in 2011 led to litter supply issues at the beginning of the growing season. No problems are apparent at this time (late February). This report is specifically for cotton, but litter is an excellent
There is considerably more interest in growing grain sorghum this year. This article gives some suggestions and resources for evaluating hybrids which could be suited for dryland grain sorghum production in Mississippi.
Find below the final version of the 2011 Cotton Official Variety Trial. During 2011, small plot cotton variety trials were conducted near the following locations; Clarksdale, Rolling Fork, Schlater, Senatobia, Starkville, Stoneville, Tribbett, and Verona. Variety trial data is segmented
Warm winter weather has promoted wheat to begin growing much earlier than normal this spring. This can make decisions regarding nitrogen application timing quite challenging and different from field to field. This newsletter will give several pointers to help make good decisions.
This is a brief review of the many agronomy, breeding, pest management, soil fertility, and water conservation research projects funded by the Mississippi Rice Promotion Board.
Stripe rust was detected in a Bolivar County wheat field last Monday morning (January 30, 2012). The report is the first of stripe rust from MS in 2012 and the second report of the disease from wheat east of the Rocky Mountains.
