Cotton Efficiency Survey

Professor Jeff Dorfman has helped develop a cotton survey from a research project funded by the Georgia Cotton Commission designed to help Georgia cotton farmers improve their production efficiency. Producer involvement in this research project only involves filling out a questionnaire on various cotton inputs, farm qualities, and personal experience.

You can find the survey at http://www.georgiacottonfarmers.com/.

Sprayer Clean Out

Thanks to UGA Extension Weed Scientist Dr. Eric Prostko for this update on sprayer cleanout. There is obvious concern about sprayer cleanout after application of Enlist Duo, Engenia, Fexapan, and Xtendimax. Dr. Prostko encourages all applicators to read and follow the specific sprayer clean-out instructions listed on the herbicide labels. Here are some useful links:

2016 Thomas County Dryland Cotton Variety Trial Results

2017cottonproductionupdate

Tuesday, we opened our production meeting season with our Cotton Production Update. We passed out the results of our dryland cotton variety trial here in Thomas County. Dr. Jared Whitaker has run statistics on the results, with varieties ranked from top to bottom in this image. Jared also included loan value and total value.

This is just our trial in Thomas County. We also want to look at multi-year data and results from trials across the state. Here are results from 2015 and 2016 on farm variety trials from Dr. Whitaker.

2017 Using Pesticides Wisely Trainings

Cotton and soybean varieties with tolerance to auxin herbicides (2,4-D or dicamba) are being commercialized. Prior to making applications of dicamba to dicamba-tolerant cotton/soybean or 2,4-D to 2,4-D-tolerant cotton/soybeans in Georgia, growers will be required to attend the training “Using Pesticides Wisely”. The training will focus on helping applicators/growers make wise decisions when applying not only 2,4-D and dicamba but all pesticides. Growers are strongly encouraged to bring their applicators with them. Attendance is suggested for all on farm applicators to confirm that they have been provided the best management practices when applying all pesticides. 

Growers who attended 2015 or 2016 trainings, as long as they registered, are not required to attend the meeting again. However, they are welcome to attend as many times as they like. The trainings have resulted in 1499 Georgia growers completing the required training. A survey conducted of these trainings noted 99% of growers felt the training was worth their time and 98% of them believed the training would help them increase on-target pesticide applications. If you have questions concerning your registration, please contact your local county extension office.

For growers who have not previously attended this training, options for 2017 are provided below. Select a time/location and RSVP, at least 2 days in advance, to the specific location for attendance. The required trainings will cover a 2 to 2.5 hr time period and will provide pesticide re-certification credits.  Snacks and drinks will be provided (no meal).

Implications Of Bacterial Boll Rot

At our Georgia Association of County Ag Agents (GACAA) meeting, we get to see presentations and posters of work done around the state. I wanted to share this poster done by Holly Anderson in Ben Hill County, EVEN THOUGH our conditions this year were as less conducive for boll rot as they have been in a long time.

We’re normally wet in our area and this is a concern of many growers. Dr. Kemerait always has points about boll rot, but it is unavoidable if cotton is subjected to prolonged periods of wetness and humidity late in the growing season. This project shows the progression of boll rot from infection to harvest and potential losses.

December Row Crop Disease Update

A few things to think about with regards to disease and nematode management in preparation for the 2017 field season.

La Nina:  Our UGA Extension climatologist Pam Knox has good information available on our current conditions, but here are my thoughts:

We are currently in a “weak” La Nina situation, “weak” because the equatorial waters of the cost of Ecuador are more than a half degree COOLER than normal.  As best I can tell, the waters have been about 7/10 of a degree cooler which barely qualifies as a La Nina (as opposed to last year where we had a robust and sure-enough El Nino).  So what does this mean? During La Nina years, the Southeast tends to (“tends to” means more often than not, but not always..) experience warmer and drier winters. Because we have a weak La Nina, this forecast could change.

How does our current “La Nina” impact our recommendations?

  1.  Drier is not a good thing as it may mean we don’t fill up irrigation ponds for next year.  It my mean we have a lot of trouble establishing cover crops this fall.
  2.  Warmer temperatures may mean that kudzu, volunteer peanuts, corn, cotton-regrowth, etc. pathogens (like those that cause soybean rust and southern corn rust) may survive and increase longer than they would with an earlier “killing” frost.  Also, as long as the crops and volunteers are active in the field, nematode populations can continue to increase and build.  This will lead to larger populations for next season. Once the plants are killed, the nematodes can no longer feed. Once soil temps drop below 65F, the activity of the todes drops off as well.
  3.  We may get some very cold weather soon, so we may not need to worry that much; however the general prediction is that we will have a warmer winter.
  4.  The weather this winter will have some effect on TSWV and insects for next year.  It remains to be seen what and how… but it will impact them.

Cotton Variety Trial Harvest

cottonvarietytrial-harvest-015

The only good thing about having no rain is having good harvest conditions. We picked our dryland variety trial on Monday, the day before the first rain came in. All in all, I’ve heard good cotton yields this year from multiple varieties. Not a lot of difference in dryland and irrigated since rain through the season was good.

Things went really well for us on Monday, and we had plenty of help. We harvested the first two reps only, but with longer rows, it’ll show difference in varieties once the numbers are completed. We also took samples to send to the UGA micro-gin. We’re going to look at grades and turnout also. I’ll compile the information and present it at our cotton meeting on January 24th. Here are some pictures from this week:
