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
