Frequently Asked Questions

Q. Can my pets go into the treated area?

A. For non-grazing animals allow product to dry before allowing pets back into the area. For grazing animals allow weeds to die completely and re-move them before allowing pets back into the area

Q. Can I use this on my lawn?

A. NO (unless you are aiming to kill it off). Resolva Xtra Tough is a total weedkiller and will kill both broadleaf weeds and grasses—only use it on plants that you want to kill

Q. When can I replant after using this weedkiller?

A. Resolva Xtra Tough does not leave a residue in the soil. As soon as the weeds have died completely and removed, the treated area can be replanted or re-seeded

Q. Will it work better if I mix in more concentrate?

A. You must always follow the label instructions when applying chemicals. Applying a more concentrated solution would not work as well due to the active ingredient not being absorbed as efficiently

Q. Can I mix up a large quantity and store it ready mixed?

A. The product should be made up and used straight away, not stored for any time

Q. What is a tough weed?

A. A tough weed is usually one with a woody stem or has root nodules underground which are difficult to kill off completely
