Worms in Peanuts
I am getting a lot of calls about various worms in peanuts. In nearly every case, it is a complex of multiple species. It seems that the complex in the Delta region consists mainly of the rednecked peanut worm, granulate

Bacterial Blight of Cotton Update: July 13, 2012
For the second year in a row bacterial blight of cotton has been observed on numerous acres in the MS production system. Compared to 2011, twice as many counties have been observed to contain infected plant material.
Will Abamectin Provide Any Plant Bug Control?
Over the last couple of weeks I have actually gotten quite a few questions about whether or not abamectin alone has any activity on plant bugs. Plant bugs have been light this year to date and spider mites have been
Insect Trap Counts, July 4, 2012
Bollworm pheromone trap counts remain at low levels throughout the state. They are so low that we are catching more tobacco budworms than bollworms, a very rare occurence for this time of year.
Response of Cotton Varieties to Inoculation with Xanthomonas axonopodis pv. malvacearum in Mississippi
Inoculation trials were conducted during the 2011 season to determine the response of several popular cotton varieties to the bacterial blight organism. The attached blog post is a poster that was presented at the 2012 Beltwide Cotton Conferences that were held in Orlando, FL in January 2012.
R.R. Foil Plant Science Research (North Farm) Center Field Day – July 19, 2012
It has been a number of years since a field day was conducted at the R.R. Foil Plant Science Research center near the campus of Mississippi State University. To that end, a row crop field day will be held on
Southern stem rot or white mold of peanut
Discusses the life cycle, management and identification of white mold or southern stem rot of peanut caused by Sclerotium rolfsii. It includes a section on how to distinguish it from a white mold look-alike. Southern stem rot or white mold
Root-knot Nematode Observed in Some Delta Cotton Fields
Root-knot nematode damaged cotton fields have been observed in at least two fields this season. With the loss of Temik, farmers have had to rely on alternative methods to manage high nematode populations.
Insect Trap Counts, June 27, 2012
Pheromone trap catches of bollworm have been low all year and this week they were even lower. No individual trap monitored had more than 4 moths in it from the entire week. None were caught in the south Delta. Unfortunately, traps
Scouting Cotton for Bacterial Blight
Bacterial blight of cotton has once again been observed in the MS cotton production area. Angular lesions associated with the disease can easily be confused with many other foliar diseases as well as other important issues in cotton. Observe the photos for help in scouting for the disease that until the past two seasons has been a fairly rare occurrence in MS.
Ditch Bank Survey 6/27/2012
Overall, tarnished plant bug numbers appear to be decreasing across the Delta. Several things are contributing to this decline. The biggest factor is that the hot, dry weather is starting to take it’s toll on a lot of the wild

Fall Armyworms in Soybeans and Peanuts
We have gotten multiple calls over the last week about fall armyworms in soybeans and peanuts. In every case, it has been a situation where people got behind on grass control when we were getting a lot of rain a couple weeks ago. In those situations, they have sprayed the grass during the last two weeks with products such as Select or Roundup that are relatively slow acting. A lot of the grass is infested with grass-strain fall armyworm and big worms start moving over into the crop about a week to ten days after the application when the grass starts to die.
Cotton Irrigation and Plant Growth Regulator Applications
Up until this week, much of the crop throughout the state appeared to be in good shape. However, the onset of high heat combined with the lack of rainfall has made this a pivotal week for cotton in many areas
Corn Disease Update for June 22, 2012: Southern Rust Detected in Localized Areas
Numerous diseases and disease-like issues are being detected throughout the corn crop in this stage of the season. Nutrient burn, sun scald, northern corn leaf blight, gray leaf spot, and southern corn leaf rust can all be observed throughout localized areas of the Delta at this stage in the season.
Tarnished Plant Bug Update
This week has been the turning point on plant bugs and appears to be the week for the mass movement of migrating adults into cotton fields in many areas. Compared to previous years we are 10-14 days behind schedule. There have been quite a few sprays going out for tarnished plant bug this year but as a whole numbers have actually not been as high to date as many of us would have thought with the warm winter.
Twitter and Agriculture: A Perfect Union
Three years ago if someone would have told me I would be blogging, I would have said they was crazy. When we started the Mississippi Crop Situation Blog, I had to look up the definition because I did not even
Late Season Corn Irrigation and Termination
This season’s corn crop, particularly that planted in early March, is extraordinarily early. However, it will still need additional irrigation or rainfall to finish the crop out. This article discusses crop progress and methods to schedule and terminate irrigation water for corn.
Crop Update and Four Bract Squares
In general, the cotton crop in Mississippi appears to be in good shape. Some areas are beginning to need some rainfall; however, a few fields just got water off low areas a few days ago. Blooms are becoming more prevalent
Insect Trap Counts, June 20, 2012
Bollworm trap counts remain low again in all monitored regions. Tobacco budworm and beet armyworm counts are also fairly low, so it appears that worm pests are not a major problem in MS cotton production at this time. Our best
Tomato Spotted Wilt, Quick Identification
Tomato spotted wilt virus (TSWV) has historically been a devastating disease of peanuts. Given the high thrips population this spring and large population of flowering winter weeds known to be TSWV hosts, I was expecting a TSWV year. I was
Appropriate Timing for Optimizing Corn Yield Response
Interest in mid-season application of various inputs has certainly increased as we try to improve corn productivity through better management. This article discusses how corn physiology plays a primary role in determining corn yield response and appropriate management timing.
Soybean Crop Update and Management Considerations
We are all thankful for the recent rains that were received throughout the majority of the state. These rains were certainly welcomed, especially in those areas that have remained dry for the last several weeks. Many places received adequate rainfall,
Table of Peanut Fungicides Labeled in Mississippi
I have been asked for my “cheat sheets” of peanut fungicides labeled for use in Mississippi. Here are two tables, one alphabetized by active ingredient (primary a.i. if more than one a.i.) and the second table alphabetized by Trade Name.
