Timing Critical for Postemergence Herbicide Applications
A good rule of thumb is that the crop should be weed-free for the first four to six weeks following emergence to avoid yield loss.

Environment is the key component in the expression of every plant disease. Especially when considering the occurrence of seedling diseases we typically have a situation in place where inoculum is present in the soil, more than likely in high quantities,
Mississippi State University has named Dr. Jason Krutz as Extension/Research Irrigation Specialist at the Delta Research and Extension Center
Yesterday (4/30), I had a call from a consultant who found about 20% infestation of 3-4 day old SWCB in Non-Bt, V6 stage corn in the Minter City area. There were places in the field that averaged 40-50% infestation, but overall was about 20%.
Over the last several weeks corn has either passed or approached the V2-V5 stage of corn growth. During this time we have received numerous calls about corn having a yellow, streaky appearance. Many of the fields we received calls on
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.
Rice Acreage: On March 30th USDA estimated that Mississippi will plant 135,000 acres of rice. That is down 16% from 2011 and the lowest acreage since the mid 1970’s. Talking with producers and seed retailers, I would estimate that Mississippi acres will be closer 100,000 acres. There are a lot of farmers across the delta that will not be planting any rice and it has been over 40 years since they have done that. Stagnant rice prices and high urea prices have not encouraged any additional plantings. The recent upswing in urea prices will not have a significant impact on rice acres.
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.
A problem that has become increasingly common in Mississippi and across the Midsouth over the last two years is corn injury from fomesafen (Flexstar, Flexstar GT, Prefix, Reflex) carryover.
USDA released their April World Agricultural Supply and Demand Estimates (WASDE) report this morning and inside was one unforeseen surprise. Corn carry-over (the amount we keep in bins and elevators from one year to the next) was unchanged from the March estimate
Encouraging farmers to plant rice this year has been a hard sell. The rice industry is facing multiple issues that have put downward pressure on acres resulting in what will be one of the smallest rice acres since the early
Using herbicides with different modes of action is an excellent resistance management tool for glyphosate-resistant Palmer amaranth.
USDA released their annual Prospective Plantings report Friday morning (Mar 30). The report reveled that corn is the big gainer in terms of acres planted this year versus last year. Corn acres across the U.S. are expected to jump by
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.
Below is a short list of apps that I have found helpful in the agriculture world. This list is by no means the only ones available or useful. These are just the ones I found to be pertinent and can help your overall productivity. I am sure there are more apps out there that could be beneficial, but I may not have discovered them yet. As always, I welcome your comments.
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.
