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
After two months of bollworm trap catches running higher than normal, this week the catches are similar to long-term averages. Tobacco budworm catches were also about average for this time of year.
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
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
Bollworm pheromone trap catches were higher than long-term averages again this week as they have been all year, while tobacco budworm catches were about the same as long-term averages. As most corn is advancing past the green silk stage, more
Bollworm pheromone trap catches were not extremely high this week, but June overall set a new high average trap catch and it the high catches were distributed among most monitored counties. To give some perspective, the highest previous years of
Bollworm pheromone moth trap catches have continued to be very high again this week in nearly all traps across the state. Tobacco budworm trap catches were also high in a few traps, suggesting that worm pressure from both species could
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
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
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
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
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

Grain sorghum can be a consistent crop suited for dryland acreage and marginal fields in the Midsouth. It also produces many benefits when grown in rotation with our primary crops. This article outlines important planting practices and management tips needed to grow a successful sorghum crop.
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
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.
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
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

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
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
We have been getting some questions about what to expect this upcoming season with RBSB in soybean. While we have had a few freezes and cold snaps this winter, we do not believe we have had a cold enough winter
