No doubt this is a very late planted crop by Mississippi standards, so I was a little surprised when numerous thrips calls started coming in about a week or so ago. Usually thrips issues are much worse on cotton that is growing off slow due to cold weather or any number of issues that may slow growth.
With all of the rainfall that we have had around most of the state, there have been a lot of questions about the impact on seed treatments. In general, most of the seed treatments that are being used in all crops are water soluble. Typical levels of rainfall should not have a negative impact on the efficacy of seed treatments, but excessive rainfall may.
The 2013 Scout School dates have been set. The first will be June 4th from 9:00 a.m -12:00 p.m. at the Delta Research and Extension Center in the auditorium of the main building. The last one will be on the main campus of Mississippi State University in the Clay Lyle Entomology Building conference room.
According to the National Agricultural Statistics Service in Mississippi, there were 4.5 days suitable for fieldwork for the week ending Sunday, May 19, 2013. Favorable conditions allowed for more field work to be completed. Operators were able to plant more corn, soybeans, and cotton. Soil moisture was rated 1 percent very short, 1 percent short, 52 percent adequate, and 46 percent surplus.
In 2012 Kudzu bugs were found in four counties in Mississippi on Kudzu. All finds were along major highways suggesting they “hitchhiked” in on vehicles. The counties were Warren, Lauderdale, Montgomery, and Carroll. In the last 2 weeks we have
Due to the rain and cold weather this spring a much larger percent of the soybean crop will be planted later than normal. There have been several questions lately about whether or not we should still include an insecticide seed
I have been asked several times over the last week about the need for thrips control now that we have more optimal planting conditions. This is a good question and I will attempt to provide some valuable insight about thrips control in both cotton and peanuts.
Earlier this week Transform WG insecticide from Dow received a full Section 3 label for use in cotton.
I am starting to get numerous calls about stink bugs in heading wheat. It is not uncommon to find stink bugs in wheat after head emergence. However, it takes extremely high numbers to cause economic damage to heading wheat. With this
Stink bugs damage small corn by feeding through the whorl or side of the stem hitting the growing point which either causes “dead heart†or severely stunts the plant. Severely stunted plants may not die but essentially become a weed. In many cases, corn that has been fed on without hitting the growing point will recover. Even if the growing point is not hit, in some situations where stink bugs feed through the stem you will see irregular growth.
According to the National Agricultural Statistics Service in Mississippi, there were 2.7 days suitable for fieldwork for the week ending Sunday, April 14, 2013. Dry conditions during the first half of the week allowed for some fieldwork to be done. Wet conditions in the last half of the week slowed or stopped all fieldwork. Soil moisture was rated 40 percent adequate, and 60 percent surplus.
This is an important question right now with the weather conditions that we have had over the last few weeks. A considerable amount of corn and a little bit of rice has been planted over the last 3 to 4 weeks. In most of those fields, the crop has either just emerged or has not emerged yet.
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.
On February 7th 2013, Mississippi State University hosted the first annual “Future of Agriculture Graduate Student Competitionâ€. The goals of this event were to provide students an opportunity to present their research findings to a diverse audience that included growers, consultants and industry personnel and interact with people from different segments of the agricultural community.
The Mississippi State University Extension Service conducts large plot, on-farm variety trials each year. These trials are intended to complement the small plot Official Variety Trials (OVT) that are conducted under the guidance of Dr. Bobby Golden. Large plot trials

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
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.
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
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.
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.

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.
