UGA Cotton Entomologist, Dr. Phillip Roberts briefly discusses the importance of scouting cotton for boll retention, the level of tarnished plant bugs currently observed in earlier planted fields, and sweep net thresholds in the latest “Pest Patrol” Update (4:07 minute runtime).
We want to maintain boll retention at 80% or higher.
Thresholds at:
1st two weeks of squaring = 8 plant bugs per 100 sweeps
3rd week = 15 plant bugs per 100 sweeps
