Could you share more information about the plants that you mowed and that you suspect killed your llama? What type of plant was it? If you're unsure, please attach pictures.

Hello again,
I now see the information in your subject line; I apologize. Tansy ragwort can come back even after mowing. If it is a small area, you can hand-pull it or use an herbicide labeled for tansy ragwort. If there is a lot of tansy ragwort across a big area you may have to look into pasture renovation options.
