Has anyone tried concentrated vinegar for crabgrass eradication? I use 30 - 
60% vinegar for pH adjustment on my tomato crops, and all my neighbors come 
by and get some for their weed control. Personally I am too busy to sepnd 
time on weed eraditication, but since my neighbors come back every year for 
more, I imagine it works for them on some weeds. Vinegar from the grocery 
store is about 5% acidity, and that is not what I am referring to. This is 
strong stuff! My tomatoes are certified organic, so this vinegar we use is 
acceptable to USDA organic standards. I also give my neighbors a liitle yucca 
extract to add as a surfactant, but I can't imagine that it is all that 
necessary.
