We're seeing a lot of tansy in 2024. It seems the biocontrol agents aren't as plentiful, but they'll likely rebound in the next year or two and the populations of tansy should dip at that point. Livestock owners that are still finding a lot of healthy tansy in their fields at this time of year might consider cutting it if they don't see active biocontrol occurring. Tansy will soon go to seed.
