Frequently asked questions about Wilson WEED OUT products

The active ingredient 4-chloroindole-3-acetic acid is based on a natural plant hormone found in peas and broad bean plants. WEED OUT is a selective herbicide. When sprayed on broadleaf weeds, it triggers the plant to wilt and die.

When used as directed, WEED OUT is safe for people and pets. When spray has dried, people and pets can enter area.

Do not water the lawn within 4 hours of application or when rain is expected. Once WEED OUT is applied to a weed, it will take up to 4 weeks for the weed to completely die. WEED OUT will not affect or kill weed seeds that have not germinated yet. If a weed seed germinates after WEED OUT is applied, an application to this new weed will need to be made.

Visible effects on the weeds (wilting) can be observed within 24 hours of spraying. Weeds will then die over a 4-week period.

WEED OUT is effective, giving excellent control of dandelions and plantains and top growth control of fall hawkbit, hawkweed, cinquefoil and black medic in turf, among others.

No. WEED OUT will have no effect on grass or lawns. Because it is a selective herbicide, it only affects weeds that are listed on the label. Grass that is accidentally treated may temporarily turn brown but will recover.
