Additional soybean rust has been detected in MS as of last Thursday. At present, 5 counties (George, Issaquena, Jefferson, Pearl River, Pike) contain extremely light soybean rust infections in either commercial soybean fields (George, Jefferson, Pike) or in soybean sentinel plots (Issaquena, Pearl River).
There is some late-planted Mississippi corn which has not reached physiological maturity. This corn may have its yield reduced somewhat by severe problems or stress. Included is a chart which may help assess potential corn yield reduction or risk.
Bollworm counts plateaued throughout the state this week after rising the last two weeks. Bollworm larvae can be found in most susceptible crops, but pressure is still somewhat light compared to recent years. Tobacco budworm and beet armyworm pressure remains low.

Corn harvest will be upon us much sooner than normal and expectations are generally much higher than recent years. However, we still need to get this corn crop out of the field and safely deliver it to market. Methods to successfully harvest your corn crop may vary depending on several factors.
Numerous foliar diseases in our soybean production system are being observed. Frogeye leaf spot, aerial blight, Cercospora blight, and southern blight have been observed on numerous acres at this time.
This year started out with most folks expecting higher than usual bollworm numbers due to the mild winter. Couple that with increased corn acres and the perfect storm was thought to be brewing. This is why entomologists get “shifty†when
Southern rust continues to be a topic of conversation throughout the MS corn production area. Presently, the disease can be observed at low levels in a patchy distribution throughout the Delta. However, there are likely some fields that contain hot spots of the disease. Scouting continues to be necessary in situations where a fungicide application could be beneficial. But, the necessity to apply a fungicide will be dependent on several important variables.
Aphids have really been blowing up recently in cotton across Mississippi, so I wanted to give a quick update on our bioassay results from this year. To date, I have not tested a single colony that was susceptible to neonicotinoids.
For the second week in a row, bollworm pheromone trap catches were up sharply throughout the state. They are now in a range more typical of catches in previous years. Tobacco budworm catches were up some in the Delta this
On Friday July 13th a former graduate student from Clemson was traveling through the Vicksburg, MS area where she stopped at a gas station and noticed six adult kudzu bugs on a vehicle in close proximity to a kudzu patch.
Late-emerging hemp sesbania is problematic at harvest due to its height, woody stem, and the fact that its black seed contaminate grain samples.
Soybean rust has been detected for the first time during the 2012 season in George County in southeastern, MS. Additional information regarding the specific find as well as management scenarios are included in the blog update. Stay tuned for additional information regarding the presence of soybean rust in the MS soybean crop on the blog, at www.sbrusa.net, and through the free telephone hotline (1-866-641-1847) that provides information regarding the presence of soybean rust in AR, LA, and MS and is sponsored by the Mississippi Soybean Promotion Board.
Over the past week we have been getting a significant amount of rain across most of Mississippi. Unfortunately, most insects don’t mind the rain. Other than spider mites and aphids, we will likely have to continue managing insects in all crops despite the rain.

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
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.
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
Bollworm pheromone trap catches were higher in all regions this week. Reports from field scouts also indicate that bollworms are being flushed more commonly from fields, so expect to see more bollworm larvae in the near future. Bollworm catches are still
The World Agricultural Outlook Board of USDA released their monthly World Agricultural Supply and Demand Estimates report (WASDE) this morning, July 11. The report revealed what most had feared, a much lower per acre yield than trend would suggest. The
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.
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.
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 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.
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
