Peanut Maturity Checks
Cotton Defoliation (10/6/25)
From Dr. Camp Hand – UGA Extension Cotton Specialist
“Dodging rain and overcast weather is the story of this week. Believe I have said it in this email before, but I really like 3 clear days for defoliant to work really well. May not get that this week, but I understand that when it is time to go its time to go.
Reminder about rainfree periods – thidiazuron is the biggy here. 24 hours, but can be reduced to 12 hours when mixed with a phosphate (i.e. Folex/DEF).
Depending on where you are, looks like we may have some rain Thursday, but the forecast is constantly changing so who knows. Overall, the trend seems to be warmer temps early in the week, followed by highs in the 70s towards the end of the week, then temps rise again next week.
Thoughts on rates – with rain being fairly widespread on the western side of the state, and chances on the east side of the state later this week, I still think we need to be in the 4+ oz/acre range with our thidiazuron. I’ve been seeing more regrowth with some of these smaller rain showers happening. In terms of Folex/DEF, 8-10 oz early in the week, with maybe 12 oz late in the week. Ethephon needs to the in the 32 to 42 oz/acre range.
