Mississippi Crop Situation Podcast

Green Stem in Soybean

One of the issues that growers notice this time of year in soybean is green stem.  Green stem could be classified as a disorder since there are different factors that contribute to soybean stems remaining green after pods have dried.  The challenges with green stem include increased harvest moisture and reduced harvest efficiency.  Trent called into the Crop Doctors’ Podcast studio to discuss green stem with Jason and Tom. 

Italian Ryegrass Management – Crossover Episode with Weeds AR Wild Podcast

MSU Extension Weed Specialist Dr. Jason Bond recently joined Tom Barber from the University of Arkansas and Charlie Cahoon from North Carolina State University for an episode of the Weeds AR Wild Podcast. They covered several topics related to managing Italian ryegrass, including paraquat resistance in North Carolina, emergence patterns in the different states, and timings and product selection for fall residual herbicide treatments.

Corn And Soybean Harvest Report

Drs. Trent Irby and Erick Larson, MSU Extension professors, visited the Crop Doctors’ Podcast studio in Stoneville to talk about corn and soybean harvest across Mississippi. They cover harvest progress, preliminary yield estimates, and observations from 2023 collected in their on-farm hybrid/variety trials.

Soil Sampling Dos and Don’ts

Dr. Corey Bryant, MSU Extension Agronomist specializing in soil fertility, sat down in the Crop Doctors’ Podcast studio in Stoneville to visit with Drs. Jason Bond and Tom Allen about soil sampling.  Topics includes sampling depth, timing, strategy, soil moisture, and which nutrients could be applied in the fall.

Rice Harvest and the Rice Festival

September is National Rice Month.  MSU Extension Rice Specialist Dr. Hunter Bowman visited the Crop Doctors’ Podcast studio in Stoneville to talk with MSU Extension specialists Drs.

Advanced Planting Work at MSU

Dr. Wes Lowe is a repeat guest and an assistant professor from the Department of Agricultural and Biological Engineering at MSU.  He and first-time guest Dr. Mike Mulvaney, an agronomist in Plant and Soil Sciences, visited the Crop Doctors’ Podcast studio in Stoneville to talk about their work in advanced planting technologies.  This work is looking at ways to increase planting speed in soybean as well as evaluating different equipment modifications to make the increased speed a reality for farmers in Mississippi.

Defoliation Arrives Early in Mississippi Cotton

Brian visited the Crop Doctors’ Podcast studio in Stoneville to offer a late-season status report on the cotton crop across Mississippi.  Extreme dry weather in south Mississippi has led to the crop in that part of the state being classified as poor in many areas.  In other areas, the cotton crop is progressing at a more traditional pace with defoliation the next major input for the crop.  Defoliation information can be found in the Midsouth Cotton Defoliation Guide at   https://www.mississippi-crops.com/wp-content/uploads/2022/08/2022_Midsouth-Cotton-Defoliation-Guide.pdf.  Look for updates to this guide soon. 

Goosegrass Problems in Midsouth Row Crops

Larry Steckel from the University of Tennessee calls into the Crop Doctors’ Podcast studio in Stoneville to discuss what have become annual problems controlling annual grass in row crops.  Larry, Jason, Hunter, and Tom hit a range of topics related to grass management.  The take home messages are that grass control has been a problem across the area in recent years.  Chemical antagonism and herbicide resistance are factors in reductions in control, but there are other factors that influence the effectiveness of herbicide applications as well.

Perennial Problems with Rhizome Johnsongrass

Daniel Stephenson from the LSU AgCenter called into the Crop Doctors’ Podcast studio in Stoneville to share his experiences with rhizome johnsongrass problems in Louisiana.  Multiple resistant johnsongrass has spread to different regions of Louisiana.  Most recently, populations of evolved resistance to the ACCase herbicides like clethodim. Rotating to corn or sequential treatments with glufosinate (Liberty 280, etc.) are the best options for managing this species currently.
