Enlist Soybean Variety Update for Georgia - 2022 (Prostko)

At the recent Laurens County Weed Meeting, I was asked if UGA has any information about the performance of Enlist soybean varieties.  The following is a quick summary of the yield performance of Enlist soybean varieties tested in the official UGA-OVT Tests in 2020 and 2021 (DM = Don Mario; AGS = AGSouth; MS = MorSoy; SH =Southern Harvest):

Results of the UGA-OVT soybean tests can be obtained at the following locations:

Reviton For Burndown Weed Control (Prostko)

Last week, I received quite a few questions about a relatively new herbicide sold under the trade name of Reviton. Marketed by Helm AG (https://www.helmag.com), Reviton is being promoted for use in the pre-plant burndown market.  At this point in time, neither Culpepper nor I have enough data/experience to make a science based "official" UGA recommendation.  Basically, Reviton is being tested in tank-mixes with Roundup (glyphosate).  I have no problems if a grower wants to try some out on a few acres (but not on 100% of their acres).  Here are a few facts about Reviton that you might find helpful:

Trade Name: Reviton 2.83SC

Common Name: tiafenacil

Herbicide Family: N-Phenyl-imides (same as Valor or Sharpen)

WSSA MOA: Group 14 (PPO inhibitor)

Labeled Use Rates: 1-3 oz/A

Crop Rotation Restrictions: Corn/wheat = 0 days; soybean/cotton = 14 days; peanut = 120-180 days depending upon rate (we are working on this one).
