Hi I'd like to find a substitute of neem oil that is
local (to where I live)
Basically neem oil comes from India I guess, or south east Asia since it is a tropical/subtropical tree.
According to M. Phillips in his book "The Holistic Orchard" neem oil is described as an
insect repellent, and inhibitor of molting cycles of various pest species...The constituents of unalterated neem oil that play a huge role in countering disease are the immune stimulants and the fatty acids (page 143).
What other substances are there that can easily be found/produced, say in Europe, may have similar characteristics and can substitute neem oil?
