Time of Day Sampling and Stink Bugs
This is some old data from 2007 but it is still relevant today. How does time of day effect stink bug populations? When this small test was conducted we did not have redbanded stink bugs in our system but I

Southwestern Corn Borer Traps, August 8, 2020
Although most corn across the state is beyond the susceptible stage, southwestern corn borer traps were very high in some counties with multiple traps exceeding 100 moths per trap.
Southwestern Corn Borer Traps, August 1, 2020
Southwestern corn borer trap counts increased again this week in several counties. Traps in Leflore, Carroll, and Tate counties exceeded the current threshold of 100 per trap. As a reminder, corn is considered safe from yield losses from southwestern corn
Southwestern Corn Borer Traps – July 25, 2020
Overall, southwestern corn borer trap numbers are beginning to decline. Only one location in Leflore county exceeded the threshold of 100 per trap this week.
The Use of Biological Insecticides for Bollworm Management in Soybean
There are several biological insecticide options labelled in soybean; however, the most readily available and widely used product is Heligen. In the last week, many people have asked about the use of Heligen with the low bollworm numbers showing up
2020 Bollworm Management in Cotton and Soybean
This last week there have been reports of bollworm eggs starting to show up in Mississippi Cotton. Generally speaking, in a normal year the bollworm flight would begin around July 4th, and peak around the 15th. The wet spring pushed
Southwestern Corn Borer Traps, July 11, 2020
Trap count continue to increase in many regions of the state, but few are at threshold. As a note, the 2 traps that captured high numbers of moths in Tate county last week were knocked down this week and are
Rainfall and Insecticide Efficacy
With the increase of rain showers this week and tarnished plant bug numbers starting to pick up in some places, now is a good time to revisit the impact of rainfall on insecticide performance. Rainfastness is a complex topic because
Southwestern Corn Borer Traps, July 4, 2020
Trap counts for southwestern corn borer are highly variable this week. We did have two locations in Tate and Leflore Counties that exceeded the threshold this week. As a reminder, thresholds for southwestern corn borer suggest spraying non-Bt corn 7
Southwestern Corn Borer Traps, June 20, 2020
This is our first week of reporting southwestern corn borer trap counts. We had some numbers reported last week but they were extremely low (0-2). This week, a couple of traps started to pick up more moths, so we may
Early Season Plant Bug Management Utilizing Square Retention
With the season progressing and the onset of pinhead square, square retention will be an important factor in early season plant bug management. Prior to bloom, monitoring square retention is highly recommended as an additional tool to compliment sweep net
Foliar Thrips Control Options in Cotton: Pros and Cons
Thrips pressure to date has been a mixed bag. Some areas have reported treatable numbers, while in other areas seed treatments have held well. Going forward, should you need to treat thrips with a foliar insecticide there are a few
Calibration of In-Furrow Sprays
As we finally move into drier conditions and cotton planting is starting full swing, more and more folks are adopting in-furrow sprays for thrips control. We have had several questions regarding calibration of in-furrow sprays. Below are are few tips
Redbanded Stink Bug Survey: Week of 4/27/20
We have sampled enough areas at this point to feel reasonably certain that some areas will experience issues with RBSB this season. To what extent is yet to be determined. We will likely not continue the weekly surveys in weeks
Redbanded Stink Bug Survey: Week of 4/20/20

Bollworm Outlook for 2020
The 2019 season was one of the most challenging years we have had from a bollworm standpoint in both cotton and soybeans. The issue was not from a numbers standpoint where the numbers overwhelmed the traits and foliar insecticides. It
2020 Grain Sorghum Hybrid Suggestions
This article lists those grain sorghum hybrids which have produced superior yields in the Mississippi Grain Sorghum Hybrid Trials. This information should improve your ability to select well-adapted sorghum hybrids for your farm based on independent performance testing.
True Armyworm and Stink Bug in Wheat
Armyworms: Over the last few days we have had several reports of true armyworms showing up in wheat. Most of the calls received so far have reported numerous worms at the ground level starting to defoliate up the plant. Once
True Armyworms in Corn
We have gotten numerous calls over the last week about true armyworms in seedling corn. Although this is not extremely unusual, the widespread occurrence of high true armyworm numbers across the southern region in wheat and corn (and grass in

Redbanded Stink Bug Survey 4/2/20
This year has been unusual to say the least with the COVID-19 outbreak. During this time, worker availability has become our limiting factor. It has ultimately limited our ability to conduct as many state wide surveys with student workers at
2020 Recommendations for Controlling Thrips in Cotton
Not much has changed since last year in regards to thrips control via insecticide seed treatment. Thrips are considered the number one pest of seedling cotton. Tobacco thrips are the species that are encountered more than 90% of the time
