Cotton Defoliation (Week of 10/7/24) – Camp Hand
First part of the week, it looks like highs in the 80s, lows in the 60s (maybe even the 50s). But then we drop off on Wednesday where highs are in the 70s, lows in the 50s and even as low as the 40s. Starting to feel like fall thank goodness.
If your growers decide to use the three way, I’d be looking at 4 oz/acre Dropp, 12 oz/acre tribufos (Folex/Def), and 42 oz/acre Prep. I’m using a higher rate of Dropp because of the rain we have all gotten in the last few weeks, and a higher rate of Folex because we are cooling off.
For those that are comfortable using Ginstar/Cutout/Adios/etc., this week looks like the week to use it. I’d be looking at at least 6 oz/acre of Ginstar, on up to 8 oz/acre particularly later in the week. I would also add Dropp to that mix to help with the regrowth issues caused by significant rain in the last few weeks (1-2 oz/acre should be enough). 42 oz/acre Prep with that.
Of course, you can always switch Folex with a PPO inhibitor (Aim, ET/ETX, Reviton, etc.) if you have a unique situation.
Reminder that adding diuron by itself to the defoliation mix is off label.
Post-Harvest Tropical Spiderwort/Benghal Dayflower Control (Prostko)
Field corn growers who do not control tropical spiderwort/Benghal dayflower in the fall after harvest are missing a HUGE opportunity to reduce seed-rain back into a field. Failure to control this plant in the fall is one reason why many Georgia growers continue to have major problems with this weed.
Check out the following data/pictures from a test that we currently have in a Grady Co. harvested corn field (Thanks Cale!). You will note that the most effective treatment at this time was a split application of Gramoxone 3SL @ 32 oz/A + Induce @ 0.25% v/v. I would expect better control from the other treatments if they would have been applied earlier to smaller plants and/or also included a COC or MSO (I was trying to save $$ and determine if a tank-mix with a “loaded” glyphosate would be adequate).
Since we are not likely to get a hard freeze until ~November 15 in south GA, there is still plenty of time left for tropical spiderwort/Benghal dayflower to produce viable seed. Viable/ripe seed can be produced within 14 to 22 days after aerial flower opening.

Here are a few images of some of the varieties from Irrigated Peanut Variety Trial (131 days old). Installed are irrigated and non-irrigated trials in Cook County that includes several varieties. These trials should produce local data (Irrigated and Non-Irrigated) on how these varieties perform in Cook County.
