Over the last several years we have seen a consistent response in wheat yield when a pyrethroid was used during the late winter months (late January-February). Often when this application goes out it is very difficult to find aphids at
The results from the Second Annual Future of Ag Graduate Student Competition are included in this post.
Over the last several years there has been a media blitz surrounding the decline in honey bee populations around the globe. It seems like the science changes daily as to cause of the problem. Most believe it is a complex
Attached please find the agenda for the Delta Ag Expo in Cleveland, MS. Make careful note that the dates of the meeting have changed from previous years due to a minor scheduling conflict with the Bolivar County Exposition Center.
Since 2011 we have seen a decline in efficacy of thiamethoxam treated cotton seed against tobacco thrips. This has led to the increase of foliar applications in mid-south cotton acres. Recently Syngenta has confirmed that populations in the mid-south region
The 2013 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University from December 2 – 4, 2013. The 2013 Row Crop Short Course will begin with an irrigation symposium hosted
The 3rd annual joint MEA/MAPPAN/MWSS annual meeting will be held next week at the Bost Extension Building in Starkville, MS next week. The dates of the meeting are Monday and Tuesday October 21-22. We have a very informative and exciting
This week marked the first reported appearances of sugarcane beetles in sweetpotato fields in Mississippi for the 2013 growing season. The sugarcane beetle is a relatively new pest of sweetpotato in Mississippi. However, in recent years, heavy sugarcane beetle populations
Since the last update several new counties have been added to the list in MS. Currently we 33 counties positive for Kudzu Bugs. Out of the 33 counties, 21 have positive finds in soybeans.
Virus-infected soybean material has been observed almost statewide this season. The high numbers of bean leaf beetles can be blamed for some of the observed viruses; however, bean leaf beetles are not the only insects that can vector soybean viruses between plants. This specific blog update presents information on the three most commonly encountered soybean viruses in the MS soybean production system.
Over the last month we have had numerous questions about terminating stink bug applications in late season soybeans. Typically we manage stink bugs until near harvest but there are several things to consider before making an application to control stink bugs in beans beyond R6 growth stage.
Soybean looper has started to show up in soybean and a few applications have started in some fields. We have several good options to manage soybean looper and all of them should be considered. Belt has become the go to insecticide for looper control in a lot of situations over the last couple of years.
Now that early planted beans are drying down quickly and insect pressure is increasing on late planted soybeans in some areas, many are asking when it is safe to quit spraying insect pest in soybeans. For most pest in soybean
I have looked at several fields over the last couple weeks that should be considered safe from yield loss from insect pest. Keep in mind that termination rules for insects in cotton do not mean the crop is “bug proof” but
Bollworm moth trap counts were lower at nearly every location this week compared to last week, indicating that bollworms are primarily in the larval stages at this time. Tobacco budworm trap counts were also low, so if a field is clean, new infestations
As is typical for this time of year, bollworm pheromone counts were higher this week, particularly in the Delta. These moths are presumably those that developed in corn ears, and will now be seeking out hosts for another generation, likely
Bean leaf beetle numbers have been much higher than they have been in the last couple years. We have actually made bean leaf beetle targeted sprays on a number of acres this year. Yield loss is caused by defoliation and
Trap counts were generally steady to slightly lower this week compared to last week for both bollworm and tobacco budworm. As has been the case all year, counts are higher than in 2012 but slightly lower than long-term average catches.
Seems like we are adding new counties every week. We are now at 24 counties total with 16 of those having kudzu bugs found in soybeans. At this time we have actually treated a field or two for kudzu bugs in
For the second week in a row, tobacco budworm counts are higher than average for this time of year. Bollworm catches were fairly typical for this time of year, so in non-Bt crops where both pests develop (like soybean), a
This week we added four new counties for positive finds of kudzu bug. All finds were in soybeans. This weeks new counties were Benton, Noxubee, Lawrence, and Issaquena.
Several insect pests have started to show up in cotton over the last couple of weeks. In most cases in the Delta, applications have shifted from targeting plant bugs to targeting plant bugs plus at least one other pest. In most of those situations, tank mixes with multiple insecticides are needed to control the whole complex. In this update, we will attempt to cover all of the current pests and highlight some control options.
With the exception of the last three years, stink bugs have always Mississippi’s number one insect pest of soybean. There are many species of stink bugs in MS soybeans but the three predominate species are Southern Green, Green, and Brown
Trap counts for tobacco budworm were sharply higher this week in the MS Delta for the first time this year. Bollworm counts were also somewhat higher in the Delta compared to last week. However, from a historical perspective bollworm counts
As expected based on field observations, trap counts for bollworm were higher this week. They are not higher than historical averages, but are definitely high enough to cause economic infestations in some fields. Tobacco budworm pressure exists, but remains low, so most Heliothines
