Products that contain sulfentrazone like Dismiss or Surge should work fine--if--you protect your vegetables with a spary shield made of cardboard.
Likewise Sedgehammer.
I am not sure if either have any soil residual. Follow label instructions. Don't get any spray on the fruit.

I'd have to check to be sure but I don't think any of these products are labeled for use in vegetable gardens.

Sulfentrazone does remain active in soil for some time,
why not just use a non selective like glyphosate

Don't eat beans, corn, cucumbers, melons, peppers, rice, or tomatoes sold in markets if halosulfuron unsafe for consumption. It is sold as Sandea herbicide for application around fruit trees, vegetables, sugarcane, and most grain crops. http://www.cdms.net/LDat/ld9I9004.pdf

Sulfentrazone is a bean, cabbage, pea, soybean, tomato, and sugarcane herbicide. http://www.cdms.net/LDat/ld3LT005.pdf

Label rates for those applications are the same as what is used on turf and ornamentals. I am wise to the fact that most of what is used in the T&O market is primarily used in production AG. A lot of hoops were jumped through to get products originally approved for AG into use in lawns. The EPA required absolute proof that T&O uses would not endanger human health. A lawn is not like a field where human contact can be prohibited for up to 21 days for some of the most toxic materials. A majority of the insecticides in AG were either never approved or else pulled out of the T&O market.

Also don't eat small grains, such as wheat. SU herbicides are used on them also. Certainty has an ag label under the name maverick. I think they have dropped maverick and added it to the out rider label. Like greendoctor said. Most t/o labels were previously used under ag labels for years

Nick,
Sedgehammer and such products containing sulfentrazone should not be applied near or within close proximity of any garden plot.
These herbicides work on shoot and root systems. This means that it must reach the roots through systemic action. There is soil activity.
