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
Corn Disease Update: June 26, 2018
Over the past week the corn disease situation in MS has changed. Several foliar diseases are starting to be observed in our production system. However, the vast majority of the leaf spots present are not yield-limiting issues.
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
Considering an R3/R4 Automatic Fungicide Application in Soybean?
Numerous questions over the past several weeks regarding automatic foliar fungicides applications in soybean have been made. The current blog post should help guide decision-making regarding the R3/R4 automatic fungicide timing.
Plant Growth Regulator Use in Cotton
Numerous questions have came in over the past 7-10 days regarding managing cotton growth with plant growth regulators. While every situation can be unique with respect to cotton growth and development and subsequent plant growth regulator use, the slides given
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
Could Weather Limit Effectiveness of your “Tassel Shot” Application?
As the Mississippi corn crop approaches tassel stage, weather has fluctuated from dry to rainy conditions during recent weeks. Thus, how may this affect how the corn will respond to mid-season application of various management inputs, including nitrogen fertilizer or other products? This article will discuss factors that could dramatically affect corn response.
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
Soybean Disease Update: May 19, 2018
Soybean root diseases have started to be observed in the Delta. Over the past week several calls have been received regarding the presence of southern blight. Dead seedlings along with white mycelial growth below the soil line is a common observation in fields where southern blight occurs.
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
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.
2017 Soybean OVT Foliar Disease Ratings: Maturity Group V FINAL
The MSU MG V OVT soybean locations were evaluated for disease during the 2017 season. Multiple diseases were rated at multiple locations and are provided in this post by herbicide trait. Cercospora blight, Septoria brown spot and target spot were the three most commonly encountered diseases during the season.
