Soybean Variety Selection Consideration: Do Not Spray Dicamba Near High Value Crops

Author:  Comments Off on Soybean Variety Selection Consideration: Do Not Spray Dicamba Near High Value Crops

Dicamba training is well under way across the state.  As of last week we have had over 1500 applicators who have taken the dicamba training.  That should be about 60% of the total number of folks that will need to take this training. Please remember if you’re the operator of the sprayer you must go through the dicamba training.  Moreover, in Tennessee you must also be a Certified Pesticide Applicator to apply dicamba.

It is clear to me that once again in 2018 Tennessee will plant a large majority of Xtend cotton.  The change will be that the herbicide trait platform for soybean will move from roughly 60% Xtend in 2017 to greater than 80% Xtend this year.

My concern is that we have fields in this state where we have no business spraying any form of dicamba in June or July. These would be fields near high value crops like tobacco, vineyards, greenhouses and vegetable production. Continue reading


Glyphosate-Resistant Barnyardgrass in Tennessee: Mechanism of Resistance and Practical Managment

Author:  Comments Off on Glyphosate-Resistant Barnyardgrass in Tennessee: Mechanism of Resistance and Practical Managment

Barnyardgrass has been confirmed glyphosate-resistant in Tennessee.  Field and greenhouse research conducted over the past few years strongly suggested glyphosate was no longer effective on barnyardgrass sourced from fields in some southwest Tennessee counties.  Just in the last few month laboratory research conducted by USDA weed scientist Dr. Vijay Nandula at Stoneville, MS confirmed the mechanism of glyphosate-resistance (GR) as reduced translocation.

Author:  Comments Off on Launch of New Soybean Insect ‘App’

A new web-based field guide for soybean insects has been launched. This site performs like an ‘app’ wherever you have cellular service and provides general information about common pests, suggestion for samplings, recommended insecticide treatment thresholds, photos, and management recommendations (including insecticide selection).

This site is complimentary of the cotton insect field guide and disease guides for soybean, cotton and wheat developed by Dr. Heather Kelly. You can access the “UT Disease and Insect Field Guides” directly at http://guide.utcrops.com/ or from the menu on the UTcrops News Blog at https://news.utcrops.com/.

Tip – Save the UTcrops News Blog website to the home screen of your Android, iPhone or iPad to have app-like access to content including this news feed, the above field guides, UTcrops.com, and other content.
