Know before you buy
Yes, CattPlex is formulated for both aquatic and landscape environments. However, because it is a non-selective herbicide, it will kill any plant it touches, so be careful to apply it only to the specific weeds you want to remove.
CattPlex is designed to be safe for swimming immediately after the application has dried on the treated vegetation. There are no mandatory waiting periods for human or animal contact once the product has settled.
Yes, CattPlex is a non-selective herbicide, meaning it does not distinguish between weeds and desirable plants. You must avoid spraying or allowing drift to touch any plants you wish to keep.
To achieve the recommended 1.5% solution, mix 2 fluid ounces of CattPlex per gallon of water. Ensure you mix it thoroughly in your sprayer before application to maintain consistent potency.
CattPlex is a systemic, post-emergent herbicide. It is absorbed by the leaves and travels down to the root system, ensuring the entire plant is eliminated rather than just the surface growth.
Yes, when used according to the label instructions, CattPlex is safe for humans, fish, livestock, pets, and birds. It is also safe to use the treated water for irrigation once the product has been applied.
