This probably belongs in the gardening section, but I thought the good people here would be more likely to know. Does anyone know the effects of using sulfentrazone near edible vegetables? The sulfentrazone would be 'painted on' rather than sprayed.

I have yellow nutsedge invading a new raised vegetable garden bed that is fully planted/seeded out with a wide variety of plants, strawberries, peppers, radish, beets, lettuce, onion etc. The nutsedge is very young (1/4-1/2" tall) and when I pull them it does not seem like most of them were connected to a nutlet like I have seen in my lawn. I want to get control of the nutsedge ASAP, but if sulfentrazone will kill or contaminate the nearby vegetables I would wait until the bed was harvested before applying.

Lastly, is pulling nutsedge by hand just ineffective or can it actually worsen the issue? I would prefer to just hand weed the area if possible.

Sulfentrazone is applied around and next to a range of edible crops. Including strawberries, tomato, beans, soybeans, and sugarcane. AG name for the product is Spartan 4F.

I would use a garden shovel and get it out by hand trying to get the roots too. When it is young it is easier to control.

Thanks for that helpful info. The Spartan 4F label eases my mind quite a bit.

Thanks. I believe I am getting the roots as well, but if it is actually connected to a nutlet that nutlet is in the underlying clay soil, not the garden "soil" which is 100% leaf compost.

As a farmer's grandson, I know there are crazier things sprayed in fruits and vegetables. What is allowed for application to lawns is strictly because of its low toxicity. The chemicals that were banned for lawn application did not go away entirely. Most of them are still allowed on fruits and vegetables.

Gly will kill sedges, is very cheap and it has no soil activity. Is there a reason you want to go with the sulfentrazone instead?

I can't speak for the OP, but I have the same problem in my garden with nutsedge and I won't spray glyphosate because any overspray will also kill the vegetables. A gust of wind and that stuff will drift right onto your tomatoes.

Glad this thread popped up, I have sulfentrazone a plenty :nod:
