Mid-South soybean variety testing database survey

Growing regions often cross state lines but variety test information is typically reported by state. To provide stakeholders with a clearer picture of variety performance, a project is underway to develop a web-based, Mid-South soybean variety testing database that allows end-users to summarize and filter yield, quality, and phenotypic data based on location characteristics that cross multiple states. This research is being performed as a collaborative project with the University of Tennessee, University of Kentucky, Virginia Tech, NC State, and University of Arkansas and is funded by the United Soybean Board. Input from those involved in soybean production (grower, seed industry, Extension, crop advisor) is important for developing a product that best meets the needs of stakeholders. If you are interested in providing input for this research project, the survey can be found at soybeandatabase.questionpro.com (respondents must be 18 or older). If you have any additional questions regarding this project, please contact the lead PI, Dr. Virginia Sykes, at vsykes@utk.edu.

2020 CST handout_full

A special thanks to all cooperators, agents, and all others who make the County Standardized Trials Program a success.

With Covid limiting in-person meetings and office visits, I want to make available the 2020 CST handout.  The above link is available for you to use in assisting variety/hybrid selection for the coming season.  Agents, feel free to print and send out or send this attachment to your row crop producers via email.  The full report above contains data from 2019 and 2020 for corn and soybean, 2020 Wheat, and 2020 Cotton.

The following links are segments of the full report to simplify searches through all 2020 CST data.

Soybean Herbicide Trait Summary

Herbicide resistant traits available in soybean continue to increase.  It does not seem that long ago that there was either Roundup Ready or conventional soybean.  There are no less than eight different soybean herbicide resistant traits available today with the most recent being XtendFlex soybean.  Continue reading

Good Time to Scout for Weeds

Author:  Comments Off on Good Time to Scout for Weeds
Pigweed that has escaped dicamba + S-metolachlor + glyphosate on 4 to 6″ weeds followed 20 days later with dicamba + S-metolchlor + glyphosate: Montgomery County, TN. Sept 1, 2020

Some have been concerned about losing dicamba due to court or EPA rulings. Everyone should be more concerned about losing dicamba and 2,4-D to Charles Darwin’s theory. Weeds developing herbicide resistance has caused the loss of many more herbicides than anything a court or the EPA has ever done. It’s not even a close race.

This is particularly true for Palmer amaranth. The newest development is that Palmer amaranth has evolved dicamba resistance here in Tennessee. We are in the beginning stages of Palmer amaranth, yet again, becoming a major problem due to the loss of a herbicides’ utility on that weed. Continue reading
