Summary

​The tobacco thrips is an early-season pest of seedling cotton and is most prevalent in the U.S. mid-South and Southeast. Both adults and immatures can injure seedlings, causing delayed maturity and yield loss. There are two current control options for thrips—at-planting insecticide treatments and rescue treatments—and issues associated with both include resistance, weather, and disease pressure. Recommendations for future management are to use organophosphates (OPs) with caution (be early!); to distinguish between recolonization and control; to apply good seed treatments; to plant ThryvOn in high-pressure areas; and to utilize the thrips predictor model.
