How long before cattle and sheep are allowed to graze after a chemical application?
Tordon and Banvel can be applied even if the pasture has grazing cattle present. However, do not transfer the livestock from treated areas to pastures or cropland with sensitive broadleaf plants for at least 12 months without first allowing seven days of grazing on an untreated grass pasture. Otherwise urine may contain enough herbicide to cause injury to sensitive plants. The waiting period after treatment with Banvel varies from seven to 90 days, so consult the label before using.
