Judging by our research plots as well as walking some cotton and soybean fields most Pre applied herbicides are playing out about 7 to 10 days quicker than last spring (Picture 1). The frequent rain would most likely be the reason for this. Continue reading
JACKSON, Tenn. – The University of Tennessee Institute of Agriculture will host the annual Weed Tour next Wednesday, June 15 at the West Tennessee AgResearch and Education Center. The guided tour will feature 60 weed management research tests in corn, soybean and cotton as well as a demonstration of herbicide symptomology. Continue reading
The call of the last week was easily “my cotton looks like #&*^!”. The main reason for cotton looking bad was the cold wet spell over Memorial Day weekend that seemed to last longer. That poor cotton growing weather then catalyzed pre-applied herbicide injury in some cases, seedling diseases in other cases and has likely made a bad thrips window even worse across most every field.

Large rainfall events and cool weather in late May strained Tennessee’s cotton crop. In some areas, individuals are considering replanting cotton that failed to emerge or cotton that appears to be just sitting. In other areas, reports of damaged or desiccated cotyledons have been reported and healthy, large cotyledons are hard to find most anywhere. In this blog, I cover a few rules of thumb to consider when determining whether or not to keep the stand and give a few words of advice to those that are considering May 30-something cotton.

The beginning of June is always a busy planting and spray window. It will be more so this spring with most of last week a wash to get much field work done. Of course, there will be a good deal of glyphosate and dicamba sprayed this week and likely some Liberty as well. With Liberty in such short supply every quart must count. This is just a quick reminder that the time of day that Liberty is applied has a large determination on the success or failure of that application.
From 2012 to 2017 we conducted a good many studies examining Liberty performance on Palmer amaranth as affected by the time of day the application was conducted. All the studies pointed to the same conclusion, that Liberty applied in the middle of the day provided better and more consistent control of Palmer amaranth than either early morning or evening applications (studies conducted in warm weather). As an example, one study (Figure 1.) from 2015 showed good control of 4” tall Palmer amaranth if the Liberty application was applied at noon compared to applications made at dawn or sunset.
In general, the best Liberty performance can be achieved when applications are made from 8:00AM to 6:00PM.
Other environmental factors also greatly effect Liberty’s weed control performance. It controls weeds best if applied on days where the high temperatures for the day are in the 80s or 90s. Also, it works best at higher humidity’s as well. In other words, a typical June or July day.

Corn, cotton, and wheat were down; soybeans were up for the week.
Harvest corn futures are now over 40 cents lower than the May 17th high of $7.65 ½. Planting has progressed substantially the past two weeks and is now approaching the 5-year average nationally. Additionally, most of the corn belt has favorable soil moisture. There is still a lot of time in the growing season, and late planting could affect national average yield, but crop conditions have improved. Weather will continue to dictate market direction until the next major USDA report, which will be the June 30th Acreage report. Continue reading at Tennessee Market Highlights.
Recent rains are welcome in parts of middle and east TN where moisture was running short, however heavy and frequent rains continue to visit west TN, making field operations very difficult. Continue reading
