[Terrapreta] Bamboo vinegar pesticide

[Robert Flanagan]

Hi Jeff,

Another product that is a bi-product of charcoal production that is said to
work as an effective pesticide is bamboo vinegar (Liquid smoke). I think you
need to find a product that still has about 2% tar and mix with water at a
ratio of 400:1 or as recommended by the supplier. I'm not sure if the
vinegar from other biomass feedstocks will be as effective but you can
always try.
Bamboo vinegar will also work as an effective herbicide when used at a ratio
up to 5:1. In China bamboo vinegar is sold at around 2000rmb/T ($265usd/T).

Hope you find a solution,

Rob.
