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 Preliminary Side Inlet/Intermittent Irrigation Results

This week I thought I would share with you the progress of our rice irrigation studies. This summer we have three producer “on farm” irrigation trials. Each producer agreed to irrigate his field conventionally through levee gates, via side inlet, and an additional side inlet utilizing intermittent flood. The producer originated irrigation on the conventional and . . . → Read More: 2014 Preliminary Side Inlet/Intermittent Irrigation Results

Late Season Potash Deficiency in Cotton

late potash 2

The evolution of cotton cultivars has led to higher yield potentials and shorter growing seasons compared to the historical full season cultivars favored in the Mid-South.  These newer, faster fruiting cultivars may require more nutrients than older outdated cultivars.  Recently, across the Mid-South, many consultants, state extension and research specialists have observed numerous cases of potash . . . → Read More: Late Season Potash Deficiency in Cotton

Keys to Diagnosing Common Nutrient Deficiencies in Rice

Potash Deficient Rice

Described below are the most common nutrient related issues that occur in Mississippi rice production and a few distinctive characteristics to key on when trying to properly identify each issue in the field.  Nutrient issues in rice can take on many appearances, but coupled with field histories some of the keys below will aid in identification.  . . . → Read More: Keys to Diagnosing Common Nutrient Deficiencies in Rice

Checking peanuts? Take your shovel! Unlikely southern blight* expression found in south Delta.

Yesterday we found our first southern blight* damage to peanuts for 2014. The timing is not unusual, we generally start finding the disease when the crop canopy closes. What is unusual is where on the plants the disease was found.

Jason and I were in a large field of peanuts between Tchula and Greenwood. An occasional plant . . . → Read More: Checking peanuts? Take your shovel! Unlikely southern blight* expression found in south Delta.

White Sugarcane Aphid Update and Impact on Midge Applications

Populations of the white sugarcane aphid are expanding and increasing across the state. We have confirmed the presence of white sugarcane aphid in grain sorghum in 7 counties in Mississippi (Fig 1) and there are likely more. The counties where white sugarcane aphids have been found include Bolivar, Washington, Humphreys, Quitman, Panola, Tunica and Oktibbeha. . . . → Read More: White Sugarcane Aphid Update and Impact on Midge Applications

Economic Benefits of Properly Managing Multiple Inlet Rice Irrigation

With water being one of the most expensive inputs of the rice producer, utilizing methods to limit the amount of water used makes economic sense.

Figure 1.

Adoption of multiple inlet irrigation has allowed producers to reduce water consumption. Water use with multiple inlet has translated into an 18% (fig.2) reduction in water cost over straight levee . . . → Read More: Economic Benefits of Properly Managing Multiple Inlet Rice Irrigation

Trap Counts, June 20, 2014

Bollworm trap catches were up in the Delta region this week to levels about normal for this time of year. Most bollworm eggs will be laid in corn at this time when many corn fields are at silk stage. University research has consistently failed to show any benefit from spraying for bollworms in field corn at this . . . → Read More: Trap Counts, June 20, 2014

Importance of Monitoring Square Retention in Young Cotton

Square retention is a critical component of early season plant bug management. I would strongly encourage you to take square retention counts along with your sweep net counts prior to bloom. Not only does this help in the decision making process of treating plant bugs, but it also helps you to get a better idea of how the products you are applying are working. Numbers alone can be deceiving when adults are steady moving into the field. When large numbers of adults are migrating into a field it is not uncommon to have as many or more plant bugs 4-5 days after a spray than you did before you sprayed and it still would not equate to a control failure. . . . → Read More: Importance of Monitoring Square Retention in Young Cotton

Armyworms Showing up in Grassy Fields Moving to Soybeans

Over the last few days I have started getting calls about fall armyworms showing up in soybeans.  We see some of this every year, and it is primarily related to larvae moving off of a grass host after a Roundup application kills the grass but this year it is much earlier than most.

Nearly every caterpillar pest species . . . → Read More: Armyworms Showing up in Grassy Fields Moving to Soybeans
