Grass killer that won't harm grape plants

Question

I am a small vineyard owner trying to find a grass killer that won't kill my grape plant roots. Please note it is only grass I am dealing with. Can you advise?

I've heard that vinegar can kill weeds, so maybe it will kill grass. If you can make your own it would totally be an organic cycle of life.

Thanks for your help but that`s what I have been using. It also kills the vine if you get within 3 feet of the grape vine. The plants roots cover 3 feet around.The person who comes up with the right formula solves Napa valleys problem too. If you hear of anything please let us know. Thanks again.

Sorry but there is no way to attack this situation with weed killers. The only other thing you can try is to smother the weeds out with heavy black plastic and cover the area with mulch.

Boiling water works great if the weeds aren't right at the plants base.

Using a product like Roundup, which contains the nonselective herbicide glyphosate, will have NO EFFECT at all on the grapevine AS LONG AS YOU KEEP THE SPRAY OFF THE LEAVES OF THE GRAPEVINE. You can put a kitchen funnel over the end of your sprayer wand so the cone shape faces toward the ground. That will prevent the spray from accidentally splashing or drifting onto the grapes. Seriously: the chemical is absorbed THROUGH THE LEAVES (blades) of the grass or any other plant. It will affect only what it touches. It will NOT travel through the roots in the soil to affect any other plant. Some people actually paint the herbicide solution on the unwanted plants with a paintbrush, which helps protect the surrounding plants from overspray or drifting. Be sure it's not a windy day. But a nice layer of cardboard or many thicknesses of newspaper will also choke out the unwanted vegetation by preventing it from getting the sunlight it needs to live.

Jo Mercer · Answer

Grapevines have thin bark that can allow absorption of glyphosate (e.g., Roundup)herbicides. If you have only grass to contend with, fluazifop (Ornamec and Fusilade are a couple of brand names) is a grass-only herbicde that may be labelled for use around grapes.

Roundup is being banned around the world, very toxic to humans and insects.  Be careful, I wouldn't use the stuff.
