2021 Cotton Focus Video Series: Cotton Diseases ‘Across the Fence’ by Dr. Bob Kemerait

Bob Kemerait - People | Plant Pathology

I’m extremely excited to introduce the presenter for our third segment of the 2021 Cotton Focus Video Series- Dr. Bob Kemerait, Professor and Extension Specialist for the Department of Plant Pathology at the University of Georgia.  Dr. Kemerait’s program covers corn, cotton, peanuts and soybeans for the state of Georgia. As many of you know, Georgia cotton growers are faced with big challenges every year, including boll rot, Bacterial blight, Cotton leafroll dwarf virus, Fusarium wilt, nematodes, Target spot, Areolate mildew and seedling diseases.  Dr. Kemerait’s program guides his growers through each of these challenges.  While we face our own unique challenges, I always find it beneficial to learn about challenges faced by other regions and I believe understanding these issues from other perspectives makes us better at producing within our own environment.

On behalf of Dr. Heather Kelly and myself, special thanks to Dr. Kemerait for taking the time out of his extremely busy schedule to deliver this presentation.  I should also add, Dr. Kemerait is on Twitter.  I thoroughly enjoy following his profile- his posts are very informative and often entertaining; who else do you know that has video of a turtle eating a cotton plant?  You can find his profile here.

Again, thank you Dr. Kemerait!


2021 Cotton Focus Video Series: Grass Management by Dr. Larry Steckel, Clay Perkins

Our second series of presentations for the 2021 Cotton Focus Video Series are from Dr. Larry Steckel’s program.  Dr. Steckel and his PhD student, Clay Perkins, will be presenting  two topics for us- the first is ‘Grass Management in Xtend and Enlist Cotton’ and the second is ‘Characterization and Management of Glyphosate-Resistant Junglerice’.  We are extremely blessed to have Dr. Steckel in Tennessee and I’m excited to have these two very important topics covered, especially after the challenges we’ve faced with grasses in recent years.

2021 Cotton Focus Video Series: Thrips and Bollworms by Dr. Scott Stewart

Author:  Comments Off on 2021 Cotton Focus Video Series: Thrips and Bollworms by Dr. Scott Stewart

To kick off the 2021 Cotton Focus Video Series, we are extremely grateful to have two videos from Dr. Scott Stewart- one discussing updates on thrips and one discussing updates bollworms.  As many of you know, Dr. Scott Stewart has recently accepted a new role as the Director of the West Tennessee Research and Education Center.   While we all hate to see him leave his current position, we are definitely excited to have him remaining on the team and I am very thankful he was willing to take time out of his busy schedule to still develop and deliver this content!  Dr. Stewart has also recorded a presentation on plant bugs; we will be posting that a little later in this series.

Cotton Focus VIRTUAL, video series to be posted weekly on blog

Author:  Comments Off on Cotton Focus VIRTUAL, video series to be posted weekly on blog

After much deliberation, the decision was made earlier this year to move Cotton Focus to a VIRTUAL event.  Instead of making all presentations within a single day, we will be posting a few presentations each week on this blog (news.utcrops.com).  We’ve got some great content to share with you and I believe this plan will allow us to deliver it in a manner that best fits your schedule.  Most of these videos will be approximately 15 minutes in length and we plan to keep these videos up indefinitely.

Sign up for our weekly emails to be notified when new content is posted or check the Cotton page of UTCrops.com (https://utcrops.com/cotton/) for a list of all current content.

For those that are in need of pesticide or CCA points, please watch the blog mid-March for a quiz.  Questions from that quiz will cover the content covered within the videos.

Defoliation Strip Trial Overview, insight to performance in cool conditions

Author:  Comments Off on Defoliation Strip Trial Overview, insight to performance in cool conditions

 

On September 18th, we applied a defoliation strip trial in Gift, TN.  The field was 85% open with juvenile and mature leaves present.  As you likely recall, this was immediately before a cold snap.  Night temperatures for the next five days were 54, 55, 55, 59 and 57. In this blog, I describe the concoctions applied, share a brief video of the results 13 days after the initial application, and highlight a few important take-homes from the video. Continue reading
