Cotton Field Tour/Turnrow Talk – Brooksville, MS – July 12
Field tour from 9 – 10:45 A.M. A field tour co-hosted with Dow AgroSciences/Phytogen will be conducted under the leadership of Drs. Dodds and Catchot. The program for the field tour is as follows: Phytogen Variety Overview – Kerry Saylors –
Cotton Disease Update: July 6, 2017 UPDATED (7/10/2017 @ 6 PM)
Bacterial blight of cotton has shown up in younger cotton in east and west MS. At present, 10 counties have been observed to contain bacterial blight cotton. To date (July 6), target spot has not been observed in the MS cotton crop.
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.
Early Season Plant Bug Management with Diamond
Most of the cotton across the Delta is squaring now and plant bug applications have started to go out on most fields. We are catching a lot of plant bugs in flowering soybeans right now and the corn should start
Southwestern Corn Borer Trap Counts – June 30, 2017
Overall, southwestern corn borer trap numbers are increasing across the state. The thresholds in the control guide suggest treating 7 days after traps reach 50 moths for pre-tassel corn and 100 moths for tasseling corn. As a reminder, corn is safe
Cotton: General Crop Update
The fourth of July is typically associated with cotton blooms in Mississippi. While some fields are blooming or will do so in the next few days; a number of fields are still one to two weeks away from blooms appearing. In general,
Corn Disease Update: June 24, 2017
Increased reports of disease in the corn crop in MS have been made over the past week. Normally, as corn matures, the incidence and severity of corn diseases observed with increase. Presently, common rust, Diplodia leaf streak, northern corn leaf blight, and southern rust can all be observed in our corn production system; however, southern rust has only been observed on an extremely limited number of acres to this point in the season.
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.
Keys to Field Identification of Common Versus Southern Rust in Field Corn
Diagnosing common and southern rust in the field can oftentimes be difficult. Subtle differences between the two diseases can occur at different parts of the growing season as well as sections of the crop canopy.
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.
Considerations for Rice Water Weevil Management in 2017
We have been getting several calls about adult rice water weevil adults and adult feeding in rice that has gone to flood. In fact, it appears that we are experiencing higher than normal populations this year in many areas of
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.
Thrips and Herbicide Co-Applications
There is no question that we are seeing increased tolerance to the seed treatments with tobacco thrips in cotton. We made an effort this year to encourage the use of acephate either in-furrow or as an overtreatment to the normal
Another Row Rice Example
Here is an example of grower ingenuity. This grower planted a flat field of heavy buckshot clay and was unable to construct levees due to rain. The field was ready to flood so he decided to give row rice a
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
2017 Cotton Maturity Guide
The updated 2017 cotton maturity guide can be accessed using the link below. Keep in mind that maturity differences depicted in this guide are in an “everything else being equal” scenario. A number of factors can affect maturity including (but
When Should I Park My Cotton Planter?
It may be the understatement of the year to say that this spring has been very challenging for the agricultural community in Mississippi. Cool, wet weather seems to disappear then return, wind and sandblasting has caused severe damage to emerged
Are you Behind on your Corn “Tassel Shot” Application?
The Mississippi corn crop is generally on pace to tassel earlier than normal this year. Thus, how may this affect how the corn will respond to mid-season application of various management inputs, including nitrogen fertilizer and other products? This article will discuss factors and distinct scenarios that could dramatically effect realistic corn response.
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
