Corn and Cotton Producers’ Prevented Planting Decision

20 May 2019
Author:  Comments Off on Corn and Cotton Producers’ Prevented Planting Decision

Federal crop insurance programs have a prevented planting provision that can protect producers from the financial losses and risks associated with not being able to plant the intended crop within the desired planting period. Revenue Protection, Revenue Protection with Harvest Price Exclusion, Yield Protection, and Area Risk Protection insurance policies pay indemnities if producers were unable to plant the insured crop by a designated final planting date or within any applicable late planting period due to natural causes, typically drought or excess moisture. This post highlights several components of those provisions and provides a few examples.

Questions continue to arise on management of glyphosate-resistant (GR) Johnsongrass in corn, soybean and cotton. GR Johnsongrass continues to become more of an issue with each passing year.  The main threat with Johnsongrass is in corn where there are few POST applied options. Continue reading →

Ryegrass escaping glyphosate plus dicamba burndown

Clearly this year,  many are having trouble managing ryegrass and poa.  Questions began months ago and continue today and have ranged from tactics to burn them down before planting to how to control them in a standing corn crop. What has become abundantly clear is that glyphosate is no longer an effective burn down option for either species across much of the state. Continue reading →

AMS or Glyphosate Mixed with the Low-Volatile Dicamba Formulations – Which One Lowers Spray Tank pH the Most?

Author: and  Comments Off on 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

Author: and  Comments Off on 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

18 Mar 2019
Author:  3 Comments

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.
