Soybean is a leguminous crop that obtains its nitrogen (N) from an association with a bacterium in the soil called Bradyrhizobium japonicum. The association between the soybean and the bacterium takes place in nodules that form on the soybean roots
Scouting for wheat diseases is most important once the flag leaf emerges. However, foliar diseases can occur throughout the growing season. In some cases wheat diseases differ by season based on inoculum pressure as well as environment.
Included in the current blog post is an updated disease scouting calendar. The timing of observations of some of the diseases included has been changed and some additional diseases that continued to be observed throughout the MS corn production system are included. Be mindful that foliar corn diseases can be observed throughout the entire season. Scouting for disease should begin shortly after emergence especially given that seed and seedling-associated diseases can impact corn stand as well as replant decisions in severe situations.
Much like the last three years, as rains delay corn planting progress, concerns arise regarding whether you will have ample opportunity to plant your corn crop in a suitable time window. This article states yield expectations and new guidelines for late corn plantings based upon MSU research.
Barnyardgrass that is allowed to survive and produce seed in soybean can cripple a rice weed control program the following year.
Wheat diseases have been few and far between this winter. Little wheat was planted in the fall of 2015. However, in some key areas, rust diseases (leaf and stripe) as well as bacterial leaf streak have been observed on wheat.
Suggested herbicide programs in Mississippi soybean have been updated to address multiple resistance to glyphosate, ALS, and/or PPO herbicides in Palmer amaranth.
Mississippi State University will be hosting 5 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.
Observing the preplant intervals for 2,4-D and dicamba prior to planting is important.
This article lists grain sorghum hybrids which have demonstrated superior productivity in the MSU MAFES Grain Sorghum Hybrid Trials and neighboring University trials. This information should improve your ability to select well-adapted sorghum hybrids for Mississippi based on University performance trials.
Barnyardgrass is the most common and troublesome weed of Mississippi rice.
Black rot is on the minds of many sweetpotato producers in the United States. The fungal disease was reported in North Carolina in 2015, and there have been at least three diagnosed incidence of black rot in Mississippi since last
There are a number of factors to consider when selecting a cotton variety which includes variety performance, traits contained within that variety, and seed treatment package. However, as a whole, maturity of a given variety is not given a tremendous
Although commodity prices have not been exciting for any crop we grow, Mississippi is expected to see cotton acres increase as much as 40% this year. As we have been traveling the meeting circuit, the common denominator has been, “What inputs can we cut in an off year?” This has been asked of all crops lately, not just cotton. It seems that seed treatments are the first thing that comes up during this conversation in every crop; however, this is not a viable option in cotton.
As everyone knows, cotton varieties are being introduced and pulled from the market quicker than ever before. The speed with which varieties come and go can make it very difficult to determine where to place a given variety and how
Environmental factors play a substantial role in nitrogen fertilization for wheat producers in the Mid-south. This article gives guidelines for application timing, fertilizer sources, rates and other important practices which may improve your wheat productivity.
The preplant interval for clethodim application before planting a grass crop (corn, rice, grain sorghum) is real and should be strictly observed.
Mid-South Farm and Gin Show convenes in Memphis February 26 If you didn’t get a new tractor, combine or other piece of machinery for Christmas, the perfect opportunity to see the latest models is right around the corner. The 64th
The venue is the Cook Convention Center, Memphis. All available footage is taken, every inch of the Convention Center, as well as the sidewalk outside the Center on Main Street in Memphis, is filled with exhibits, machinery, equipment, and products
We posted an article last spring about utilizing several best management practices in an overall IPM program to manage tarnished plant bug in cotton. We included a pdf that highlights all of the research we have conducted over the last
Managing Palmer amaranth with multiple resistance to glyphosate, ALS, and PPO herbicides in cotton will be complicated, but control will be possible.
Find below the Final version of the 2015 On-Farm Rice Variety Trial. During 2015, small plot rice variety trials were conducted near the following locations; Choctaw, Clarksdale, Hollandale, Ruleville, Shaw, Stoneville, and Tunica. Variety trial data is presented segmented by
The entries contained in the MSU soybean OVT were screened for their sensitivity to the root-knot nematode during 2014 (and again in 2015 – data forthcoming). Contained within this blog post are the root galling responses of 142 entries as well as the yield from the RKN infested location.
Preliminary results indicate that Palmer amaranth resistant to PPO herbicides is likely in Mississippi
The Corn Hybrid Demonstration Program provides us first-hand opportunity and information to better assess hybrid performance and adaptability in Mississippi. This program provides unique opportunity to observe and evaluate plant characteristics and environmental responses of our best corn hybrids in local, on-farm demonstration plots. This is a complete summary of 2015 results.
