Redbanded Stink Bug Update 7/15/2017
We have sprayed several fields in the last 2 weeks for RBSB’s. To date, most fields have been late March planted beans that are R5.5-R6 growth stage. Most of the fields so far have been south of Hwy 82, but

Soybean Disease Update: July 1, 2017
The soybean disease situation continues to change throughout MS depending on growth stage situations in each field. Over the past week root diseases have been commonly observed. The first soybean rust of the season was observed in southwestern MS on kudzu.
Navigating Fungicide Active Ingredients
Over the past several years, fungicide pre-mix products have dominated the marketplace. Keeping up with the specific chemical classes within each product can present a challenge. Included in this blog post are some information to aid in making fungicide decisions.
Soybean Disease Update: June 18, 2017
Limited soybean diseases have occurred throughout the MS soybean production system. Observations of Septoria brown spot and taproot decline have been quite common this season. Lesions that result from herbicide injury have also been commonly observed, but should not be cause for concern.
Redbanded Stink Bugs and R3 Fungicide Applications in Soybean
Getting more calls everyday about low numbers of Redbanded Stink Bugs (RBSB) in R2/R3 soybeans. Many are asking about what to mix with a fungicide to take them out. Before jumping out too quickly, consider this, I would suspect very little
Considering the R3/R4 Automatic Application in Soybean: Time to Apply Two Modes of Action Instead of One
Over the past week calls have started to be received regarding the automatic fungicide application in soybean. On-farm, large plot trials were conducted during 2015 and 2016 to assess the benefit of several different fungicide products and to reevaluate the automatic application timing. At present, we believe that a mixed mode of action fungicide, or one that provides more than one mode of action would be more beneficial than the stand-alone strobilurin (QoI) fungicide application that has become popular over the past decade.
Redbanded Stink Bugs Successfully Overwintered In MS
In 2009 Redbanded stink bugs (RBSB) were treated in numerous areas of the state but numbers crashed in 2010. In 2013 there were a few fields treated and then they essentially were a non-issue until 2016. We have been hearing
REMINDER: 2017 Agronomic Scout Schools
Mississippi State University will be hosting 4 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. There
Flooding in Corn and Soybeans
By now I am sure everyone has seen the pictures of the flooding occurring from recent rains in across the river in Arkansas and Missouri. Compared to those states, Mississippi has fared pretty well in regards to flooding of young

Herbicide mixtures can have a large influence on barnyardgrass control with glyphosate.
Managing Target Spot of Soybean: 2016 Fungicide Trial Efficacy Results
Target spot management in soybean production systems remains a hot topic going into the 2017 season. The environment that occurred during late July and early August 2016 made us respect a disease that is often “out of sight and out of mind”. Fungicide data from two efficacy trials conducted during 2016 are included in this blog post.
Enlist and Xtend: What Buffers are Mandatory?
Labeling for new auxin herbicide products detail requirements that either restrict application or require buffers between the treated field and sensitive areas or susceptible crops.

Enlist and Xtend: What Mixtures Are Approved?
New auxin herbicide products have associated websites, which are considered extensions of the federal labels, that list additives and herbicides approved for mixture.
Target Spot Management: Thoughts from 2016 Observations
Target spot was one of the main diseases that occurred during 2016. Normally a disease of little consequence in soybean as well as cotton, severe target spot outbreaks were observed in both crops. Making decisions regarding the occurrence of target spot during 2016 are difficult since the environment during key plant growth stages was the most important ingredient for the occurrence of target spot last season.

Enlist and Xtend: What Are the Herbicide Rates?
New herbicide-resistant technologies offer the option to use herbicides previously not labeled for in-season application in cotton and soybean
Enlist and Xtend: What Can I Spray and on Which Crops Can I Spray It?
New herbicide-resistant crop options are available for 2017 in the form of the Enlist Weed Control System from Dow Agrosciences and the Roundup Ready Xtend Crop System from Monsanto.
