Roundup Poison Ivy Plus Brush Killer

Yes. This is a non-selective herbicide, meaning it will kill or damage almost any green plant it touches, including your lawn grass. Use it carefully on patios, driveways, or around fences where you want to eliminate all vegetation.

The formula is rainproof just 30 minutes after application. As long as it has had that half-hour window to dry on the leaves, a light rain or watering shouldn't wash away its effectiveness.

You can expect to see visible results, such as wilting or browning, in as little as 24 hours. Because it is a systemic herbicide, it travels down to the root to ensure the plant is fully eradicated.

You should exercise extreme caution. Because this is a non-selective killer, any spray drift or accidental contact with your flowers or shrubs will likely kill them as well. It is best used in areas where you don't have desirable plants nearby.

No, this is a ready-to-use formula. It comes with a comfort wand sprayer, so you can simply attach the wand and begin applying it directly to the leaves of the weeds you want to control.
