You must provide numerous resources and management to optimize the opportunity for corn plants to produce high yields. Of course, favorable weather plays a huge role as well. This article describes areas where we can improve corn yield potential.
What is the importance of a neonicotinoid insecticide seed treatment in soybeans? Basically it is a risk management tool. Soybean seedlings have a tremendous amount of vigor and can tolerate a substantial amount of insect injury. However, early planted soybeans can encounter less than optimal environmental conditions which can stress plants and reduce vigor. Insect injury under these conditions is an additional stress. During 2010, it is estimated that the use of insecticide seed treatments in soybeans resulted in a value of $28.8 million to Mississippi soybean growers.
Sugarcane beetles (Euetheola humilis rugiceps), have caused many Mississippi corn producers major headaches in the last decade. Ironically enough, most of the problem areas are in the Hill region of the state and not the Delta region. Sugarcane beetles are certainly present in the Delta but rarely cause widespread problems in corn (to date). Sugarcane beetle infestations are sporadic in nature but heavy infestations can be very serious and require replanting in some situations. Unfortunately there are no viable rescue treatments available, so this pest has to be managed at planting.
University Research and Extension Entomologists from across the southern U.S. participated in a survey where they rate the performance of insecticides against various insect pests in cotton, soybean, and field corn.

The 2012 Row Crop Short Course will be held from December 3-5, 2012 at the Bost Extension Center on the campus of Mississippi State University. Pre-registration is free of charge until November 30 and will be $40 thereafter including at
The 2012 Delta Crop Summit will be held on Tuesday, November 13, in Stoneville, MS. Please see the attached schedule.
As we begin to gear up for wheat planting there have been several questions regarding the use of insecticide seed treatments. We have been testing insecticide seed treatments in wheat for several years and have seen a positive response in nearly every case.
Two new insecticides from Valent recently received federal labels for use in rice. The state approval is still pending, but expected soon. The insecticides are Belay and Nipsit INSIDE. Both of these insecticides have the same active ingedient, clothianidin.
Bollworm trap counts dropped slightly from the previous week in the Delta and Central MS regions while staying about the same in the Northeastern MS region. Tobacco budworm counts also dropped back some this week while beet armyworm counts were
Bollworm trap catches were up sharply this week all across the state to levels higher than seen at any time this year. Tobacco budworm catches were also higher this week, particularly in the northern Delta region. While many crops are
Mississippi producers planted 65K acres of grain sorghum this year, up from 52K acres in 2011, and 12K acres in 2010. Grain sorghum traditionally in MS has been considered a “step child†crop that went on the worst dry land
Tobacco budworm catches were up sharply this week, especially in the northern and central Delta region. Bollworm catches were slightly higher in all regions of the state. With higher tobacco budworm catches, the proportion of worms that are budworms in
When to terminate spider mite treatments can be a very difficult decision this time of year. Spider mites can cause yield loss directly by feeding on small squares and bolls causing them to abort, or indirectly by feeding on leaves which reduces photosynthesis not allowing bolls to fill out correctly. In many ways this indirect damage would be very similar to defoliation.
Bollworm pheromone trap counts were lower in all regions of MS this week and they weren’t very high before. Tobacco budworm and beet armyworm catches also remain at low levels. Unless something dramatic happens in the next few weeks, it looks like
Fall armyworm can be a challenging pest to find and an even more challenging pest to manage in some crops. The damage that they cause and their management varies greatly from crop to crop. The reason for this is due to their preferred feeding sites on different crops and the presence of host strains.

Bollworm pheromone trap counts stayed at their relatively low numbers again this week. Moths are present in all areas of the state and larvae are being found in susceptible crops, but not at densities like the last few years. Tobacco
This is a friendly reminder that the Rice Field at Delta Research and Extension Service in Stoneville, MS will be tomorrow (July 31, 2012). Registration at Capps Center- 2:00 pm. Rice Market Outlook presentation by Milo Hamilton –
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.
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
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.
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.
