Onion Thrips Management: Learn How to Avoid Insecticide Resistance
2/15/2019
Ten years ago NY onion growers routinely lost 30-50% of their crop’s value to thrips. Since then, new insecticides have minimized loss.  Unfortunately, the new products are being used almost weekly, are expensive, and thrips can build up resistance.

Professor Brian Nault of Cornell University has developed a management approach that integrates active monitoring, higher action thresholds, and rotating insecticides to control the pest. The approach, developed in a 2014 pilot, was further tested in grower’s fields across the state. The program, funded in part by a New York Farm Viability Institute grant, demonstrated that season-long thrips control using reduced-risk insecticides and fewer applications is possible.
