Casoron 4G Herbicide is not labeled for use in lawns and could possibly injure the turfgrass if applied especially on St. Augustine or Centipede since these are already sensitivie turfgrass species.
Please view our St. Augustine Lawn Guide for more information and recommendations.
Casoron 4G Herbicide is not labeled for use around asparagus. Prowl is a liquid pre-emergent option that we carry that is safe to use.
Casoron 4G Herbicide does not specifically list ferns, lavender or buttercup on the product label as tolerable species, so we are unsure if this product would kill them or not. We would recommend reaching out to the manufacturer directly for more information on this at (800) 356-4647.
We would advise waiting till Casoron 4G Herbicide has completely dried before letting pets back in the area typically after 4-6 hours. The product is also not labeled to be used around lake, ponds, or rivers. We would recommend staying 25 ft away from any bodies of water and do not water in to the point of runoff.
Unfortunately we do not have a product that will control for up to 2 years, but we do carry Eraser Max Super Concentrate Herbicide that will prevent regrowth for up to a year. It will kill any weeds that are actively there since it is a non-selective post, but also prevent regrowth of weeds just like Casoron 4G Herbicide
There is not a liquid Casoron option available only the Casoron 4G Herbicide in the granular formulation. We do offer other liquid pre-emergent herbicides here on our site. Please check the label of the item to be sure they fit your needs.
