I have seen a few cotton fields blooming this week. Most of them were planted in early May. Some of the growers have already sprayed these fields with the first application of PGR and Boron. During this time of year, we often get “pop-up” thunderstorms that interfere with folks trying to spray cotton and washing the Pix, Stance, or mepiquat chloride off before the plant can take it up. Our cotton agronomist, Jared Whitaker, shared the information below with us recently about the rainfast time of certain PGR’s for cotton.
