Cotton Tour Sept. 9th; thoughts on defoliation

Author:  Comments Off on Cotton Tour Sept. 9th; thoughts on defoliation

The ‘turn’ this year wasn’t much of a turn at all- it was more like a crash.  In this blog, I give a few last minute thoughts on the crop, provide the preferred concoction that I would use on our earliest planted acres that will receive harvest aids, and highlight content we will cover in depth at the upcoming Cotton Tour Sept. 9 (next Wednesday).

The typical trial data release post on this blog contains little narrative.  This post is not a typical one.  In addition to providing the links to the 2025-2026 Tennessee Wheat Official Variety Trial Publication, I also recognize the efforts of both Dr. Dennis West and Mr. David R. Kincer for their combined 90+ years of service to Tennessee growers.  Additionally, I briefly share the future plans for the program. Continue reading →


Thoughts on plant growth regulation July 9th

Author:  Comments Off on Thoughts on plant growth regulation July 9th

Scattered rains have accumulated over the past week, with many receiving several inches or more. With even more rain in the forecast and many of our acres quickly entering their second and third week of bloom, the question of the week has been what to do with plant growth regulators. In contrast to previous years, the introduction of the active plinazolin (Vertento) has created a more interesting question- what can we do, from a plant growth regulator standpoint, to take full advantage of the long residual control window provided by this new product? In this blog, I outline the best approach to balance a possible opportunity to save an application cost with the risk of being too aggressive. Continue reading →


Cotton plant growth regulator guide, variety classification publications now available

Author:  Comments Off on Cotton plant growth regulator guide, variety classification publications now available
Snapshot of the 2026 Cotton Variety Guide for Plant Growth RegulationThe MidSouth Cotton Specialists’ Working Group has just released the 2026 Cotton Variety Guide for Plant Growth Regulation and a more in-depth publication entitled Plant growth regulator use in Mid-South Cotton.
The in-depth publication includes a relatively new breakdown to managing plant growth that considers variety responsiveness; current and expected growing conditions;  and plant size, measured by nodes.  It is our hope that these baseline rates, presented in Table 2 of the in-depth publication, might take some of the guess-work out of the time to initiate treatments, when to make follow-up treatments, and how much to apply in each application.  Please note that 1) the rates mentioned in the attached guide are for a 4.2% mepiquat chloride formuation; 2) a maximum single application should not exceed 24 oz per acre of a 4.2% mepiquat chloride product with a maximum season application rate of 48 oz per acre of a 4.2% mepiqaut chloride product; and 3) rates and initiations should serve as baselines but should be adjusted based on local expertise and past experiences that can be locationally specific.
