Know before you buy
No, this is a selective herbicide. It is specifically formulated to target broadleaf weeds like dandelions and clover while leaving your desirable turfgrass unharmed.
You should allow at least 7 hours after application for the product to become rainfast. If it rains sooner than that, the effectiveness may be reduced.
For optimal results, apply when weeds are actively growing and temperatures are at least 50 degrees Fahrenheit. Avoid applying during periods of extreme heat or drought stress.
The re-entry interval for this product is 0 hours, meaning you can technically re-enter the area once the spray has dried. However, it is standard practice to keep pets and children off the treated area until the liquid has completely dried.
Yes, Trimec Speed is a post-emergent herbicide. It is designed to be applied to weeds that are already visible and actively growing in your lawn.
Systemic action means the herbicide is absorbed by the leaves and moves throughout the entire plant, including the roots. This ensures the weed is killed completely rather than just having the top growth burned back.
