Dear List, we have tested wood vinegar as a pesticide on plants. It works in the case of moderate infestation, but if the infestation is severe, especially with sucking pests such as mealy bugs and woolly aphids, one has to use a conventional organo-phosphatic systemic insecticide. Biochar has never worked in our local soils, which have pH higher than 8.5. Wood vinegar has a number of organic acids in it, which may be used by the soil micro-organisms as their carbon source, so that they multiply their numbers. That the population density of soil micro-organisms is positively correlated with soil fertility, is a known and accepted fact. Therefore, any treatment, which causes the soil microbe population to rise, would automatically result in higher soil fertility. Yours A.D.Karve
