Gaucho canola system and Gaucho platinum both contain fungicides, in addition to imidacloprid, and provide protection from a broad spectrum of seed and seedling diseases. XTra Helix is produced by Syngenta, and contains the insecticide thiamethoxam. Helix Xtra contains a higher rate of thiamethoxam than Helix. As a result, Helix Xtra will provide a longer period of protection from flea beetles than Helix, but also costs more. Helix and Helix Xtra also contain fungicides that protect the seeds from a broad spectrum of seed and seedling diseases.
Research is currently underway on additional seed treatments for flea beetle control in canola.
So additional seed treatments may be available for control of flea beetles in canola in the future. Please note that lindane based seed treatment will still be available for wireworm control in wheat, barley, oats, rye, and flax. The phase out of lindane based seed treatments is currently for canola only.
