Weed killer that won’t kill grass

[Steve67]

What product would kill leafy weeds but not damage perennial rye ? Suggestions from the lawn care professionals, thank you.

I am not really a lawn lover…but might check a label on 2,4-D. I beleieve it is for broad leaf applications. Link below is related really for ag use, but I suspect maybe similar.

As mentioned - 2,4-Dichlorophenoxyacetic acid will do it! Commonly called 2-4-D, can be found in many chemicals - some more expensive than others. Spray - and then wait to see the effects and then spray again to make sure.

There's a host of reasons you really should contact your local extension agent for questions like this.
The primary reason is to enjoy success without damaging desirable plants accidently. "Leafy weeds" isn't sufficient description of what you are trying to eliminate. Weed is any plant growing where it's a nuisance. Millions of people spend millions of dollars annually to grow Bermuda lawns while an equal number of people spend and equal amount of money trying to get rid of it in crops, beds and gardens. BTW Bermuda is very leafy and eradicating it from among Rye requires diligence.

In addition to Bermuda,Crabgrass and Dallisgrass are also prevalent and difficult to control in Rye ( all of them laugh at 2-4-D)

2-4-D has been used for this purpose for a long time. It’s what is in weed and feed lawn products. But, there’s a big caveat. It will also kill shrubs and trees that have roots extending into the lawn.

It says so on the bag but people see Weed and Feed then put it on their yard without even reading label. Some put it in gardens and beds hoping to control weeds.

The only thing I will use in the garden of beds is glyphosate. And very sparingly as a spot application to kill perennial weeds. I pull, hoe or till annual weeds.

So do I and I haven't bought weed and feed for lawn in decades. I spot treat/spray weeds in lawn as needed where St Augustine doesn't choke them out.

All 3 of the active ingredients in this have been banned in Europe for years. Just saying

Weed Be Gone is effective against lawn weeds and clover. 24D alone will not kill clover.

I'm actually looking for the opposite, something to kill grass but not broad leaf vegetation or weeds, if anyone has a suggestion.

You can only get something to kill grass without harming broadleaf from an agricultural chemical distributor and will need a license or permit. It's crop specific, therefore $$.

Sethoxydim, Hi-Yield's Grass Killer, works pretty well.

Thanks! Looks like this should work. It's what popped up when I Googled "Sethoxydim, Hi-Yield's Grass Killer".
