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.

Dr. Kelly, who also serves as Extension plant pathologist in west Tennessee, said target spot historically has been less prevalent in the upper Mid-South than in fields in south Alabama and Georgia. That has changed in recent years.

“We saw some symptoms in 2013,” she said. “It came back in 2014 and 2015, and this year, 2016, is the first year we’ve definitely seen severe infestations in commercial fields. You can probably find a little bit of target spot in every field in Tennessee based on the feedback I’ve received.”

Target spot, which shows up as brown to brick-red lesions that display concentric rings as they get larger, first appeared in south Georgia and south Alabama before 2008. The same fungal pathogen causes target spot on many other hosts including soybeans and tomatoes.
