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

Lime Need and Value

Acid soils often need liming to aid crop growth and development. Fall applications provide more time for the lime to react with the soil, less stress on the human component, and better field conditions  for equipment operation.

Soil acidity problems rarely have dramatic visual symptoms. Affected areas are less hardy or vigorous in growth; the size of . . . → Read More: Lime Need and Value

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

Insect Trap Counts, August 29, 2014

Bollworm pheromone catches were lower again for the second consecutive week, suggesting that once control is achieved for current larval populations, a major reinfestation is unlikely. Tobacco budworm catches were also lower . . . → Read More: Insect Trap Counts, August 29, 2014

Fall 2014 Lime Programs

With harvest beginning, it is time to think about the next crop. Fall liming allows time for the soil to react before the next summer crop is planted, and takes advantage of the (usually) drier conditions for field operations.

Soil pH measures soil acidity, the master variable of soil fertility. Technically pH is the concentration of hydrogen . . . → Read More: Fall 2014 Lime Programs
