Allow a buffer zone between sensitive grasses and the treated area.
Allow the product to dry on the leaf surface prior to permitting traffic on the treated area.
Avoid application when heavy rain is imminent or when the soil is saturated.
Irrigation is not recommended immediately after application.

Finally, goosegrass has been added to the list of weeds Revolver controls in bermudagrass greens, tees and collars.
