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.
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.
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
(Correction to Mississippi cotton acreage change from March has been made) The much anticipated, and likely to be much debated, 2012 Acreage report from USDA was released this morning (June 29). Nationally, the report bumped up the number of acres

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
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.
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
Generally speaking, the 2012 crop is ahead of where we typically are at this time of year. Much of this can be attributed to planting earlier than usual due to warm weather conditions earlier in the spring. Blooms have already
The United States Department of Agriculture’s World Ag Outlook Board released their monthly supply and demand estimates report earlier this morning. The report was the second round of forecast for the current summer (new) crops, which is the 2012/13 marketing
The biennial North Mississippi Research and Extension Center Agronomic Row Crops Field Day will be held at the Lee County Agri-Center, Magnolia Conference Center, Highway 145 South of Verona, on Thursday, August 9, 2012, from 8:00 a.m. to 1:30 p.m.
Plant bug sprays are going out this week but overall numbers have not been as high as expected to date. This can change rapidly as plant bugs begin to move into fields from wild host plants. Click to Enlarge
Bollworm and budworm pheromone trap catches are up some from last week, but bollworm catches are still far below typical catches for this time of year. Some sampling of corn and sweet corn has confirmed the low pressure. Once corn
Transform, a new insecticide containing the active ingredient sulfoxaflor, has received an emergency use exemption for Delta counties in Mississippi for the control of tarnished plant bug in cotton. This product represents a new mode of action and has excellent

Cotton planting is all but completed for the 2012 growing season. Given current cotton prices the number of acres of cotton planted behind wheat will likely be very small this year. Cotton growth stages throughout the state range from one
Hail damage has occurred in scattered areas over the past week to ten days. Areas around Clarksdale, Sledge, and Yazoo City as well as others have been affected by hail. Deciding whether or not to replant following hail damage can
Seedling disease has been making an appearance in isolated pockets over the past week to ten days. Primarily we have been observing Rhizoctonia, also known as soreshin, on cotton in the north Delta. Seedling disease, caused by Rhizoctonia solani, is
When glyphosate was effective on most weeds, we were in a period of “weed controlâ€. However, over the last few years since glyphosate-resistant weeds have become so prevalent, we have entered a period of “weed managementâ€.
Plant bugs are still the predominant pest we are finding on wild hosts at this time. Click on to Enlarge
Sprayer cleanout after a herbicide application is a critical component to a successful herbicide application.
From time to time we send crews out to survey insect pest populations in ditchbanks adjacent to agricultural fields. This gives us an idea of what to expect later in the season based on what and how many pests we
The insect scout schools for 2012 have been set. At each scout school we will go over biology, thresholds, and scouting techniques for each of the major pests of cotton, soybean, and corn. This is a great refresher for the
