Heliothine Trap Catches, July 6, 2018
Bollworm pheromone moth traps were relatively low for the second consecutive week. Tobacco budworm catches remained low as they have been all year. I expect bollworm catches to begin to rise next week as we will be about one month
Identifying Corn Reproductive Growth Stages and Management Implications
Corn reproductive stages generally comprise nearly 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions.
Southwestern Corn Borer Traps: June 29, 2018
Southwestern corn borer trap counts were up this week in Coahoma county. As a reminder, our threshold for foliar sprays on non-Bt corn is to spray one week after trap counts exceed 100 per trap from tassel to full dent.
Heliothine Trap Catches, June 29, 2018
Bollworm moth trap catches were lower this week in Mississippi. Tobacco budworm catches remained at very low levels.
Potato Leafhoppers in Soybean
Every few years we have a surge of potato leafhopper calls in soybean in MS. This is one of those years. Potato leafhoppers strongly prefer smooth leaf soybean varieties and I suspect that the calls increase on years where popular
Heliothine Trap Catches, June 22, 2018
Bollworm pheromone trap catches for the week remained relatively high in the Delta region, especially in Washington county. Tobacco budworm counts remain low in all counties. As corn matures past silk stage, fewer bollworm eggs will be laid in corn,
Managing Plant Bugs in Cotton That is Just Starting (or About to Start) Bloom: Diamond or Not?
So far, the 2018 cotton crop is off to a good start. Good growing conditions caused cotton to grow off from thrips pretty quick and plant bugs have been fairly light so far this year. A lot of cotton has
Rainfastness of Insecticides
This article is dated but applies very well today given the pop up showers across most of the state lately. Every year when afternoon thunderstorms start popping up, the phone starts ringing about rainfastness. Rainfastness simply means the amount of
Southwestern Corn Borer Traps – June 15, 2018
We have been trapping southwestern corn borer for the last few weeks, but most traps have not caught any moths until this week. Overall, numbers are still low, but are starting to increase which may signal the beginning of the
Common Questions, Myths, and Facts About Soybean Insect Control in MS
This is a recycled article from 2012 and slightly updated but it fits well with recent calls. Sentences in italics have been added or updated since original posting. We have some of the earliest beans that are R3/R4 getting fungicide applications
Heliothine Trap Counts, June 15, 2018
Bollworm trap catches are up sharply this week for the second consecutive week, especially in the Mississippi Delta region. Most of these moths will likely oviposit in silking corn where they cause minimal damage, but early cotton and soybeans should
Heliothine Trap Counts, June 8, 2018
Bollworm trap catches rose sharply this week, especially in the Delta, signalling the beginning of another generation. Moth emergence is aligning with corn silking this year which is bad news. While economic damage to corn is minimal, larvae develop very
Heliothine Trap Catches, June 1, 2018
Pheromone trap catches for the week ending June 1 were similar to the previous week, which is similar to or slightly lower than historical averages. Tobacco budworm counts continue to be low, so most heliothine larvae observed should be bollworms
Heliothine Trap Counts, May 25, 2018
We will be posting pheromone trap catch data again this year from several counties in Mississippi to give you an idea when pressure is greatest and whether your population is likely mostly bollworm (corn earworm) or tobacco budworm. We have
Reminder: 2018 Agronomic Scout School Dates
Mississippi State University will be hosting 2 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology.
Redbanded Stink Bug Ditchbank Survey 5/10/2018
In 2017, we were able to accurately predict the threat of RBSB based on sampling ditch banks in the spring. Every year we sample ditch banks across the state to make collections of various insect pests. With most pests, such
2018 MSU Grain Sorghum Hybrid Suggestions
This article lists grain sorghum hybrids which have produced superior yields in the Mississippi Grain Sorghum Hybrid Trials and neighboring University trials. This information should improve your ability to select well-adapted sorghum hybrids for Mississippi based on independent performance testing.
Controlling Thrips in Cotton: Recommendations for 2018
Over the years many have questioned whether the use of a seed treatment is considered IPM because they are used prior to the onset of a problem. In our area, and across most of the cotton belt, thrips are considered
Bollworm Management in Bt Cotton: Things to Consider at Planting Time
As the 2018 cotton season approaches, it is a good time to look back at 2017. From an insect management standpoint, the number one thing that stands out about last year is the amount of foliar sprays that were made
Redbanded Stink Bug Ditch Bank Survey 4/15/2018
In 2017, we were able to accurately predict the threat of RBSB based on sampling ditch banks in the spring. Every year we sample ditch banks across the state to make collections of various insect pests. With most pests, such
Cool, Wet Weather, and Residue Brings Slugs
I have recently received a few call about slugs in corn. I suspect this will increase in more crops as planting continues and they begin to emerge. Slug problems usually start on corn first, then move to soybeans, then cotton in our area.
What Will Cold Temperatures Mean for Redbanded Stink Bug This Year?
Entomologist across the Mid-South have had numerous questions about how below average temperatures we have encountered this month will impact RBSB populations this year. What we know is RBSB’s are tropical insects that do not survive well in cold temperatures. We have
2018 County Extension Meeting Schedule
The Mississippi State University Extension Service will be hosting a number of county row crop extension meetings in the spring of 2018. Each meeting will cover issues specific to the area and will provide information on weeds, insects, disease, economics,
