Tracer is a new broad-spectrum Lepidoptera control compound for cotton from DowElanco. It was applied to over 270 different sites throughout the Delta region. Most plots were over 40 acres in size and comparisons were made between Tracer and the farmer standard. As bollworms were the most common Lepidoptera pest, the standards most commonly applied were pyrethroids. Across the region, Tracer's performance was better or comparable to the standards. Tracer also allows conservation of beneficials. Data were collected on big-eyed bugs, minute pirate bugs, lady beetles, lacewings, imported fire ants, spiders, predator mites and parasitic wasps. Little or no deleterious effect was noted on these species. Data from Texas and Oklahoma show that aphids are not flared after application of Tracer. Finally, beet armyworm efficacy was examined under both threshold and outbreak situations. Across all locations Tracer was comparable to the commercial standard. In conclusion, Tracer was validated in large scale trials throughout the south, providing broad spectrum worm control with conservation of beneficials. These properties, combined with the novel mode of action, make Tracer an excellent choice for resistance management.
