Organic Pesticides
In organic
growing, it is ideal to exhaust all other methods of pest control
before turning to these materials. There are a number of pesticides,
which are used largely as insecticides or fungicides, that fit into
government-determined organic standards for farmers and for gardeners.
These include sulfur, copper, oil,
neem, diatomaceous earth, Bt
(bacillus thuringiensis), and pyrethrins.
How these differ from
pesticides used in conventional growing is that these organic
pesticides come from natural sources – plants or animals. While these
pesticides can be toxic in copious amounts, they typically have a
narrow, rather than general, target range and are less persistent than
synthetic pesticides. (Remember: if using organic pesticides, they are
still pesticides and should be used only as directed on the label.)
