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
This past week we encountered the following situation. A Grower irrigated a silt loam field utilizing a surge valve. When he checked his moisture probes neither the 6” nor the 12” Watermark™ sensor had moved. What’s going on? After careful evaluation we realized that the grower had prematurely terminated the irrigation cycle.
A few weeks ago we . . . → Read More: Surge Valve Issues and Gleanings.
Now is the time to prepare for 2015 PHAUCET implementation!
Without a doubt the installation of PHAUCET (Pipe Hole and Universal Crown Evaluation Tool) on every acre of your farm is the most important water saving strategy you can implement. PHAUCET allows you to irrigate your fields uniformly with each furrow watering out at . . . → Read More: Now is the time to prepare for 2015 PHAUCET implementation!
In 2013 a new aphid pest called the White Sugarcane Aphid, Melanaphis sacchari, was detected in grain sorghum in 38 counties in Texas, Louisiana, Oklahoma, and one county in Mississippi. This species has apparently been around for years but the hosts switch to grain sorghum appears to be new. This pest can be devastating to grain sorghum if populations reach high densities. In fact, some fields have seen 100% yield loss. Another major factor is this aphid is difficult to control with currently labeled products. . . . → Read More: White Sugarcane Aphid: A Potentially Devastating Pest of Grain Sorghum
The importance of soil moisture sensors is becoming more evident as we continue forward this growing season. Today (Monday, June 16th), we received a call regarding sensor readings that were assessed early this morning. The following are the data discussed in this scenario. . . . → Read More: Is My Soil Moisture Sensor Broke?
Every year at some point during the season we seem to hit a rainy spell where it seems to rain at some point every day and we have showers widely scattered across the state. It started raining last Wednesday and we have had some rain everyday since then and it is currently raining in Stoneville right now (Monday morning). With that, the questions start about how long you need to spray before a rain to get acceptable control. . . . → Read More: Influence of Rainfall on Insecticide Efficacy
The dates for the 2014 Scout Schools have now been set. We will be providing detailed information on identification, biology, thresholds, and management of the major insect and disease pest of Mississippi row crops. These trainings can also be used to renew your insect and disease consultants license and CEU’s for Certified Crop Advisors will be provided at each. The meetings will also serve as In-Service training opportunities for MSU-ES agents as well. These trainings are great for the experienced and the inexperienced. . . . → Read More: 2014 Insect and Disease Scout School Dates Set
This is a video showing the methods used to determine the vegetative growth stages of corn or sorghum in the field. Further information can be found in the accompanying Mississipp Crop Situation blog article. . . . → Read More: Video – How to Identify Corn Vegetative Growth Stages
Vegetative growth stages of corn or sorghum are determined by counting the number of fully emerged leaves with leaf collars present. This methodology can be used to anticipate growth and determine appropriate timing of many management decisions, including herbicide application, sidedress fertilizer, etc…. . . . → Read More: How to Determine Growth Stages of Young Corn or Sorghum
We have had several calls in recent days as news gets out about the EPA’s recent label changes for neonicotinoid insecticides. The intent is to offer greater protection for pollinators in and around crops where this class of insecticides may be applied. Basically, the new language forbids the use of these products while bees are foraging and until flowering is complete and all petals have fallen off the plants. There are a few exceptions if certain criteria are met. . . . → Read More: New Neonicotinoid Pollinator Protection Labels
