2014 MSU Short List of Suggested Wheat Varieties

Combine harvesting wheat

This publication lists those wheat varieties which have demonstrated superior productivity in the MSU Wheat and Oat Variety Trials and summarizes their characteristics. This impartial information should help you better assess wheat varieties which are best suited for your farm.

2014 Cotton Varieties Planted Report

The USDA released their 2014 Cotton Varieties Planted Report on September 12, 2014.  Stoneville 4946 GLB2 was the top planted variety in Mississippi this year followed by Phytogen 499 WRF and ST 5289 GLT.  The entire report may be accessed using the link below:

2014 Cotton Defoliation Guide

Defoliation season is upon us and as such, the 2014 Mid-South Defoliation Guide has been updated and is ready for use.  Those who have worked with cotton fully understand the challenges associated with defoliation.  Further compounding an already difficult task is the forecast of uncertain weather over the next several days.  The 2014 Cotton Defoliation Guide . . . → Read More: 2014 Cotton Defoliation Guide

Soybean Loopers Showing up in Late Soybeans:

loopdef3

Soybean loopers are starting to show up in high numbers in many areas of the state. In many cases, soybeans are past the point where yield loss can occur, but there are many later planted soybeans that need to be protected for a while longer. Below are a few tips on when to treat and what to treat with. . . . → Read More: Soybean Loopers Showing up in Late Soybeans:

Identifying Soils that “Seal” and Improving Irrigation Application Efficiency in “Sealing” Soils

 

This summer we had multiple conversations with producers that either irrigated or had significant rainfall events on their field, but the soil moisture sensors below the 6 inch depth never “detected” the irrigation or rainfall event (see http://www.mississippi-crops.com/2014/06/26/is-my-soil-moisture-sensor-broke/ ). The producer assumed the sensors were “broke”, but we attributed the phenomenon to “surface sealing”. Surface sealing . . . → Read More: Identifying Soils that “Seal” and Improving Irrigation Application Efficiency in “Sealing” Soils

Foliar Soybean Disease Update: September 3, 2014

Severe Cercospora blight (late-season Cercospora).

Foliar diseases of soybean continue to be observed throughout the MS soybean production area. At present, no soybean rust has been detected in MS; however, Cercospora blight and frogeye leaf spot as well as several pod diseases (topic of the next blog post) are being observed in numerous soybean fields. . . . → Read More: Foliar Soybean Disease Update: September 3, 2014

Fungicide Phytotoxicity: Check the Fungicide Applied Prior to Blaming SDS

Severe phytotoxicity associated with a foliar fungicide application.

Phytotoxicity, associated with the application of some specific foliar fungicide products, has been observed in numerous commercial soybean fields again this season. Keep in mind that the symptoms associated with fungicide phytotoxicity will appear quite similar to sudden death syndrome (SDS). However, SDS only occurs in light soil classes. When scouting fields, keep in mind that an entire field with SDS-like symptoms might be the result of fungicide phytotoxicity, thus not a disease after all. . . . → Read More: Fungicide Phytotoxicity: Check the Fungicide Applied Prior to Blaming SDS

When to Terminate Bollworm Sprays in Late Season Bt Cotton

We have had numerous calls over the last couple weeks about small, 2-5 day old larvae, under bloom tags in Bt cotton that is near, at, or beyond cutout. All of the research done to this point suggests that cotton is safe from bollworm damage when it reaches node above white flower 5 plus 300 heat units. . . . → Read More: When to Terminate Bollworm Sprays in Late Season Bt Cotton

Reminder: Soybean Irrigation Termination Turnrow Talks – August 26, 2014

Plan to attend an upcoming Irrigation Termination Turnrow Talk on August 26, 2014 sponsored by the Mississippi Soybean Promotion Board, Mississippi State University Extension Service, and stakeholder organizations of the Delta Sustainable Water Resources Task Force. Soybean producers will have the opportunity to learn how to determine the right time to end irrigation for the season . . . → Read More: Reminder: Soybean Irrigation Termination Turnrow Talks – August 26, 2014

Soybean Irrigation Termination

We have reached the point of the growing season where we have begun to terminate irrigation in soybean. When making this decision, the goal is to make sure that adequate soil moisture is available to ensure that the soybean seeds reach maximum size. Terminating irrigation too soon can result in decreased seed size which ultimately will . . . → Read More: Soybean Irrigation Termination
