A substantial number of soybean acres have been reported to be affected by seedling disease. However, the majority of the field seedling issues can be blamed on poor environmental conditions following the planting that occurred around Easter (between April 14 and 19) and some of the residual herbicide products applied.
We have had several calls in recent days as news gets out about the EPA’s recent label changes for neonicotinoid insecticides. The intent is to offer greater protection for pollinators in and around crops where this class of insecticides may be applied. Basically, the new language forbids the use of these products while bees are foraging and until flowering is complete and all petals have fallen off the plants. There are a few exceptions if certain criteria are met.
Strobilurin-resistant frogeye leaf spot continues to be a topic of conversation. During 2012 two MS counties were confirmed to have strobilurin resistant frogeye leaf spot. Since that time a large survey has been conducted in MS to determine how widespread the resistance is within the fungal population in MS.
Fungicides have become an important management alternative for diseases such as frogeye leaf spot. However, with the addition of the strobilurin-resistant fungus responsible for frogeye leaf spot, caution must be taken when applying fungicides to not increase the likelihood of fungicide resistance from developing. The specific characteristics of the main fungicide classes labeled for application in soybean systems are outlined. In addition, a table that includes the specific components of the pre-mix products when the labeled rates are applied is included.
Fungicide resistance has continued to be a hot topic during the off-season. Since 2010, fungicide resistance within the frogeye leaf spot fungal population has been documented in several states including Mississippi. To prevent the development of fungicide resistance from increasing several important steps can be followed. Several of these specific topics will be outlined in this three part series regarding fungicide resistance.
Recently several groups in Mississippi came together and developed then adopted a set of Cooperative Standards for row crop farmers and beekeepers in an effort to increase awareness of pollinator’s and create an environment where each could coexist while minimizing any
Just to prove that 2,4-D labels can be confusing, plantback restrictions were listed correctly in the previous post, but formulations were not specified.
With the cold, wet weather, many burndown herbicide applications were delayed. This has led to a multitude of questions on plantback restrictions for 2,4-D and dicamba prior to planting corn and soybeans.
I have gotten numerous question about calibration of in-furrow rigs this year, so I am republishing an article I put up in the past that breaks calibrating pesticides down to a very easy understandable level. Proper calibration can mean the difference in control or failure of a product against the targeted pests and potentially thousands of dollars of savings to the grower.
The 62nd annual Mid-South Farm & Gin Show will be held February 28 – March 1, 2014 at the Cook Convention Center in Memphis, TN. More than 400 exhibitors from more than 40 states will be on-hand showcasing the latest
RISER irrigation approach reduces water use by 50% while maintaining yield potential.
The results from the Second Annual Future of Ag Graduate Student Competition are included in this post.
Control of glyphosate-resistant Italian ryegrass was reduced with glyphosate plus Select Max at reduced rates when combined with 2,4-D Ester and/or Clarity.
Over the last several years there has been a media blitz surrounding the decline in honey bee populations around the globe. It seems like the science changes daily as to cause of the problem. Most believe it is a complex
Included in this blog post are ratings collected for frogeye leaf spot as well as Cercospora blight from the 2013 Maturity Group V soybean variety trials. Trials were conducted in Brooksville, Clarksdale (irrigated), Falkner, Longwood, Olive Branch, Raymond, Stoneville (clay and loam). The conventional/LibertyLink trial was only conducted at the Brooksville, Falkner, Longwood, and Stoneville (clay) locations. Ratings were collected based on a 0-9 and are presented from each location for each variety so a range of ratings is available across all environments encountered during the 2013 season.

Attached please find the agenda for the Delta Ag Expo in Cleveland, MS. Make careful note that the dates of the meeting have changed from previous years due to a minor scheduling conflict with the Bolivar County Exposition Center.
Attached in this blog post are the variety trial results from the North Mississippi Research and Extension Center in Verona, MS. Harvested yield as well as variety response to natural infection from Cercospora blight and frogeye leaf spot are included in the associated tables.
Variety selection is one of the most critical management decisions associated with soybean production. Factors such as soil type, planting date, irrigation capabilities, row spacing, harvest capacity, and other crops grown all can influence the decision for selecting an appropriate
The 2013 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University from December 2 – 4, 2013. The 2013 Row Crop Short Course will begin with an irrigation symposium hosted
The 3rd annual joint MEA/MAPPAN/MWSS annual meeting will be held next week at the Bost Extension Building in Starkville, MS next week. The dates of the meeting are Monday and Tuesday October 21-22. We have a very informative and exciting
Since the last update several new counties have been added to the list in MS. Currently we 33 counties positive for Kudzu Bugs. Out of the 33 counties, 21 have positive finds in soybeans.
Virus-infected soybean material has been observed almost statewide this season. The high numbers of bean leaf beetles can be blamed for some of the observed viruses; however, bean leaf beetles are not the only insects that can vector soybean viruses between plants. This specific blog update presents information on the three most commonly encountered soybean viruses in the MS soybean production system.
Soybean disease questions still consider to be raised throughout MS. Even though soybean rust has been detected in 45 counties to date it appears we will have another season where yield losses as a result of soybean rust will be extremely limited and may only have occurred in a handful of fields. When making plans for next year consider sampling for nematodes in light textured soil classes. In addition, planting a frogeye susceptible variety in several years in a continuous soybean system may increase the likelihood of frogeye causing substantial yield loss.
While weeds can create problems for harvest equipment, many producers see the benefit of a harvest aid in creating a more rapid and efficient harvest in the absence of weeds
