I have a couple of requests for the information from the Colquitt County Cotton Production meeting that was held on March 1, 2023. The keynote speakers were Drs. Camp Hand and Phillip Roberts.
Camp informed producers about cotton varieties and the data from the 2023 UGA On Farm Cotton Variety program. The first illistration below shows how the 12 variety entries placed at all locations of the UGA On-Farm Variety program. DG 3799 B3XF yielded above the trial average 86% of the time in 2022 and 85% of the time when the data was average over the last two years (2021 and 2022).
We had one location of on farm cotton variety program in Colquitt County in 2022. A summary of the data can be seen HERE.
Dr. Phillip Roberts, UGA Cotton Entologist, spoke about thrips, whitefly and Thryvon.
Thrip management was a topic the Dr. Roberts discussed during the cotton meeting. He gave his thoughts on how the ThryvOn technology will fit into insect management in Georgia.
Whitefly was another topic that Dr. Roberts touched on. The slide below shows whitefly levels in various cotton counties across Georgia for the week ending September 2, 2022. Colquitt County was in the many fields category (many fields treated, >50%).
Has it been cold enough this winter to impact whitefly pressure this year?
I thought this was interesting. The slide below shows the cumulative degree days for SLWF for the period of November 1 to April 1 for the Tifton area. The red lines represent 2012, 2016, 2017, 2020, and 2022, which are the five worst whitefly years on record. 312 DD is required for a generation of whiteflies. The yellow line represents the degree days up to date for this year.
