Heliothine Trap Catches, July 30, 2020
Bollworm moth trap catches were up this week compared to last week as expected. Moths are emerging from corn now and will be primarily laying their eggs in cotton and soybeans at this time, so be attentive in scouting these
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
Heliothine Trap Catches, July 23, 2020
Bollworm moth trap catches were generally down this week from last week and were fairly average for this time of year. Tobacco budworm catches continued to be low, also about average for this time of year. However, as corn is
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
Heliothine Trap Counts, July 17, 2020
After reporting the first week of catches in the “normal” range last week, bollworm traps were filled with a unusually large number of moths this week, especially in the Northeastern part of Mississippi. Tobacco budworm trap catches remained at average

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
Heliothine Trap Catches, July 9, 2020
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.
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
Heliothine Trap Counts, July 2, 2020
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
Corn Reproductive Stages and Their Management Implications
Corn progresses through six stages as ears develop through reproductive growth stages. Identification of these stages can be helpful for timing development, making prudent management decisions and anticipating crop response to practices and environmental conditions.
Heliothine Moth Trap Catches, June 25, 2020
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
Heliothine Trap Catches, June 19, 2020
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
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
Heliothine Trap Catches, June 5, 2020
As I have done every year since 2007, 3 or 4 pheromone moth traps each for bollworm and tobacco budworm have been erected in agricultural regions of Noxubee, Lowndes and Oktibbeha counties. They are checked once per week and the
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
*Each week we sample, we will add to the previous weeks post with updated map and new counties This year has been unusual to say the least with the COVID-19 outbreak. During this time, worker availability has become our limiting
