Talkin' Cotton Podcast
Welcome to the UGA Cotton Team's Talkin' Cotton Podcast. This is a podcast for cotton growers, county agents, industry partners and anyone else interested in learning about science-backed cotton production and pest management. Our goal is to educate you with the most up-to-date data and information all season long. Talkin' Cotton will feature guests, such as, extension specialists, research faculty, graduate students, extension agents, industry allies and many others! Let's get into the why's of puttin' on, throwin' off and cuttin' out.

Beyond The Shed: What Your Cotton Plants Are Really Telling You
The Georgia cotton crop is showing signs of change as August progresses, with growers witnessing fruit shed across fields statewide. This episode dives deep into the natural processes driving cotton fruit abscission and whether you should be concerned about those squares and young bolls on the ground.
Our experts explain that even high-yielding cotton naturally sheds up to 60% of its fruit, with this process peaking between peak bloom and cutout when demand for carbohydrates is highest. Recent overcast weather has intensified this natural process, limiting the crucial solar radiation plants need. While concerning to witness, the team reassures growers that position and timing play key roles – fruit retention typically peaks around node 10, and once bolls reach two weeks of age, they're unlikely to shed regardless of conditions. Unfortunately, when sunlight becomes the limiting factor, management options are virtually non-existent.
As cotton approaches cutout, irrigation termination decisions become critical. Research shows continuing irrigation beyond cutout can waste $20-80 per acre with no yield benefit. The team provides guidance on knowing when to "pull the meter" and walk away, especially valuable during a year with tight margins and 67-68 cent cotton.
The conversation shifts to pest challenges, including bollrot (increasing with recent wet weather), stink bugs (Georgia's primary cotton pest), and the newly confirmed cotton jassid now present in over 40 Georgia counties. This tiny pest causes distinctive "hopper burn" that can be mistaken for nutritional deficiencies, particularly along field edges and equipment tracks.
With some early-planted cotton approaching defoliation as soon as late August, the team offers timely insights for navigating these late-season decisions. Join us September 3rd for the Cotton and Peanut Research Day in Tifton to see your checkoff dollars at work and discover the latest research findings from the UGA Cotton Team.
