Cotton growers should be patient in treating for target spot

In Delta Farm Press

Conditions in west Tennessee are setting up as conducive for target spot infestations in cotton. Or maybe not.

Heather Kelly, Extension pathologist at the University of Tennessee Research and Extension Center in Jackson, says several factors need to coincide for target spot to pose a threat to cotton. Continue reading

Target Spot in Cotton – How to identify it and management options

by Heather Marie Kelly, Extension Plant Pathologist, University of Tennessee

As cotton gets closer to blooming, scouts should be on the lookout for target spot and defoliation starting in the lower canopy.

The warm, wet weather the Mid-South has been experiencing could promote target spot in cotton fields, especially those fields that saw the disease in 2016 and are irrigated. Additional factors that increase target spot risk include higher planting rates, excessive N rates, narrow row spacing, vigorous growth, as well as hot, humid weather. Some facts about target spot: Continue reading

Spotting and managing target spot

To hear first-hand from an expert about how to manage target spot and some results of research to help, tune in next Monday afternoon at 3 PM for Dr. Austin Hagan’s webinar on target spot. Click here to register.

From an article by Tyson Raper, University of Tennessee, in Cotton Grower

As the cotton specialist for the state of Tennessee, I am constantly on the lookout for potential issues that may impact Mid-South cotton production. Over the past several years, I have occasionally observed several “target spots,” or Corynespora leaf spots, on the lower leaves of rank cotton plants. Although the number of spots and number of affected leaves are typically low, many growers have asked if the disease might be able to cause the 200-400/lb lint per acre yield penalties reported along the Gulf coast.

Don’t plant cotton in same place if you had target spot

In Delta Farm Press

Odds are that if you observed symptoms of target spot or Corynespora cassiicola in your cotton this year you’re probably going to see it again if you plant cotton in that field next year.

That’s the advice Heather Kelly, an assistant professor in field crops plant pathology at the University of Tennessee Institute of Agriculture, gave farmers attending the 2016 Cotton Tour at the West Tennessee Research and Education Center in Jackson. Continue reading

Tennessee Extension plant pathologist tackles fungicide-resistant frogeye leaf spot, receives regional award

Frogeye leaf spot has always been a bane for soybean growers, but its recent resistance to fungicides has made it even more burdensome. So University of Tennessee Extension Plant Pathologist Heather Kelly has dedicated herself to learning more about the disease so that she can develop more effective control options and teach farmers how to use them. Her willingness to tackle the problem as a relatively new faculty member at UT caught the attention of her colleagues and earned her a Friends of Southern IPM Future Leader award, which she received on March 11 at the Southern Soybean Disease Working Group meeting in Pensacola, FL.
