1) would a standard, not certified organic, surfactant from your average
chemical supplier be a pollutant and unwise to use near food crops?
I personally would not have a problem with the types of chemicals we are
looking at. But for those who have to strictly follow organic rules, it may
not be an option.
2) is a surfactant needed anyway?
My understanding is that it would make the mixture more effective. You need
a wetting agent to more easily penetrate the plant tissues.
3) with or without a surfactant would a mix of acetic and citric acid be
better that either one used alone?
This is apparently what the scientists found when they tried different
combinations of acetic and citric acid (and probably many other things too).
AllDown Active Ingredients:
Citric acid ………….......................…………………….... 5.0 %
Garlic ..…..…….....................…....……………………… 0.2 %

Looks like a 1/20 mix with or w/o a measured amount of nonionic surfactant.
I was hoping to instantly disable (cook, dissolve, whatever) the Bermuda root
systems,
which are buried extensively in a crushed rock driveway and go on 24/7
invasive forays
into adjoining garden beds.

Other Ingredients: Acetic acid, yucca extracts, water …........ 94.8 %
4) which would be a better or safer herbicide, acetic or citric acid?
Similar organic acids. Apparently there may be some synergy by having them
together in the mixture.

I'll try the 1/20 combination and report back with the resultsof my
experiment.
Thanks for help, Rick.
