Metribuzin-tolerance Screening of Selected Soybean Cultivars

🕔09:25, 1.Mar 2012

For many years, one of the mainstay residual herbicides in soybean weed control systems was metribuzin (Sencor/Lexone). One of the drawbacks to metribuzin use is the sensitivity of some soybean varieties to this herbicide. A research project conducted by Mississippi State University and the University of Arkansas screened some of the modern germplasms available to producers for metribuzin tolerance.

The reality of weed control in the Midsouth today is that the weed control season is never over. Because of glyphosate-resistant weeds, we are either in the process of killing weeds or we should be thinking about how to kill them.

Mixing Issues with Gramoxone Inteon

Mixing Issues with Gramoxone Inteon

🕔10:26, 27.May 2011

Many producers have utilized paraquat, sold under the trade name Gramoxone Inteon®, to control emerged weeds at planting. Often times a chemical manufacturer will modify a herbicide formulation to create a safer, more stable, and/or effective herbicide. However, a recent formulation change in Gramoxone Inteon has resulted in some mixing issues in some parts of Mississippi.

Are my residual herbicides gone after all this rain??

🕔11:36, 29.Apr 2011

There have been a lot of people questioning “how much of my residual herbicide is left after all this rain?” How much residual value is left may depend on what kind of herbicide was used.

Control Emerged Pigweed Prior to Planting Soybean

Control Emerged Pigweed Prior to Planting Soybean

🕔10:59, 8.Apr 2011

Soybean planting is underway in many parts of the Delta and I have already received a number of calls about pigweed already being emerged in some fields. It is absolutely imperative that these emerged pigweeds are controlled prior to planting. Early weed competition can significantly impact soybean yields not to mention we don’t have many options to control emerged pigweed in soybean.

Ground Speed Affects Spray Droplet Deposition

Ground Speed Affects Spray Droplet Deposition

🕔14:20, 11.Mar 2011

As producers prepare for spray applications this growing season, it is imperative to consider proper spray nozzle selection. As ground speed increases, the orifice size of the nozzle must be increased to maintain the desired GPA. A larger orifice naturally produces larger droplets which equates to poor coverage with contact herbicides. With this in mind, it is recommended to make spray applications at a reasonable ground speed that allows for the use of a spray nozzle that will produce a medium droplet size conducive for contact herbicides.

For the past 15 years the only herbicide program that most producers have known was the use of glyphosate in Round Ready® crops. With glyphosate-resistant weeds becoming more of an issue there has been an increase in demand for alternative control options.
