Guidelines for using insecticides to manage onion thrips in onion fields in the Great Lakes region continue to evolve as we gain more experience using them under various situations. The following guidelines provide multiple scenarios for managing onion thrips over the season in New York. The major factors used to create these guidelines are efficacy of products under varying levels of thrips pressure and the desire to follow insecticide resistance management principles.
Disclaimer: There are other insecticides labeled for use on onion for onion thrips management that also may be effective, but that are not included in these guidelines. These guidelines have been developed based on our personal experience assessing the efficacy of many different products in commercial onion fields or by assessing their performance after application by New York onion growers in their fields.
