Gooday all from the land of OZ
There has been a lot of interest in this so here is my
interpretation of some of it
This is taken from the SANET posting listed below
CAUTION - ANYBODY THAT IS GOING TO MESS WITH AN ALMOST PURE
ACID BETTER KNOW WHAT THEY ARE FOOLING WITH AND HOW TO MIX IT PROPERLY -
I was attracted to these receipes because of the synergistic
effect of combined citric and acetic acid - I have seen many drammatic
synergistic effects with chemicals over the years - you definitely get more bang
for the buck -
Burndown -vinegar (glacial acetic
acid)
500ml
- citric acid 250ml - water 750 ml to 1250ml Selective Broadleaf activity double water to 2300ml OR 10% wt acetic acid 5% wt citric acid 85% wt water There is a US patent no 5,888,938 on this (would you believe) I found this a few days ago on the SANET-MG archive and then lost it! SANET-MG @LISTS.SARE.ORG --search for vinegar and its item no 008807 May 2002 I would suggest you spend some time reading the original SANET posting before going ahead - there was quite a bit of proper testing done to back up the patent application At first you would think this is just a case of burning the weeds off - its a pretty strong brew - but the specially good result on Canada thistle - which is a real mongrel weed - would seem to suggest something more. Cheers all
