Many growers in the Mid-South apply a herbicide shortly prior to sorghum harvest to facilitate combine efficiency and suitable grain moisture. This season, this issue is even more critically important because of severe harvest problems potentially created by White Sugarcane aphid infestation. This article will discuss appropriate timing and potential outcome of such harvest aid applications.

White sugarcane aphid infestations are increasing across the state and more applications are going out to manage this pest. Over the last week to 10 days we have heard about numerous fields that have received a second application. Remember, that the Section 18 label for Transform states that no more than 2 applications can be made in a field. . . . → Read More: White Sugarcane Aphid Update – 8/1/2014
Over the past week we have had numerous opportunities to further observe spread and control of fields infested with white sugarcane aphids. We also have managed to get a couple of replicated small plot test out. Below are a couple bullet points based on recent experiences from walking numerous fields and talking to numerous folks around the state and Mid-South. . . . → Read More: White Sugarcane Aphid Update: 7/25/2014

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.

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
