AMS or Glyphosate Mixed with the Low-Volatile Dicamba Formulations – Which One Lowers Spray Tank pH the Most?
This is the second in a series of blogs on research that Dr. Tom Mueller and I did to examine some of the directions on the XtendiMax and Engenia labels. In the second test, we examined the effect on spray solution pH when AMS was added to Engenia or XtendiMax, with or without glyphosate. Continue reading
Effect on Tank-Mixture pH when Glyphosate is Added to Either XtendiMax or Engenia
With the off-target dicamba movement in recent years, Tennessee soybean growers asked my colleague, Dr. Tom Mueller, and me to vet some of the directions on the XtendiMax and Engenia labels. The goal was to come up with information to help mitigate off-target dicamba. In a series of blog posts this week, we will share our most current findings. Continue reading
Clethodim and Managing Glyphosate-Resistant Grasses
Clethodim is quickly replacing glyphosate as the “go-to” herbicide for grass control in West Tennessee. It began a few years ago as folks found that ryegrass and poa in many fields could no longer be controlled with glyphosate. In more recent years the pace has accelerated as the spread of glyphosate-resistant (GR) summer grasses like goosegrass, jungle rice and Johnsongrass have made it necessary to add clethodim to glyphosate to “prop up” the grass control.

Enlist Soybean Gains China Approval: Some Thoughts
The news this week was the China approval of Enlist E3 soybeans (soybeans tolerant to glufosinate, glyphosate and 2,4-D) for import. China also approved the import of Syngenta’s MGI soybeans. Those soybeans are tolerant to Callisto, glufosinate and Balance herbicides. My understanding is this MGI trait in soybeans still needs EU approval so unlike the Enlist E3 soybeans they will not be offered for sale this year. Continue reading
Soybean Seed Quality Concerns going into 2019
Most farmers had their fair share of seed quality issues during fall 2018, including many seed bean producers. The commercial seed supply is expected to be impacted some by weathering at harvest, with severity depending on maturity group and field location. Continue reading
Tennessee Weed Control Manual is Now On-line and BMPs for Dicamba
The 2019 Weed Control Manual for Tennessee Field Crops, Forage Crops, Pastures, Farm Ponds and Harvest Aids is now posted online. The major change to the 2019 manual is the addition of Engenia, XtendiMax and Fexapan in Xtend crops. Continue reading
Charcoal Rot: What is it and how to screen for it
The fungus Macrophomina phaseolina is a soil-borne pathogen that infects nearly 500 species of plants including soybean, cotton, and corn and causes the disease charcoal rot. What does this mean for West Tennessee farmers? Continue reading
