The rules for what qualifies as organic are inconsistent with the perception and enforcement is so lax that local news stations have made headlines this summer by doing pesticide testing on organic labeled foods. And find it.
So called organic pesticides, such as a rotenone-pyrethrin mixture, can be toxic. At recommended application levels it takes 7 applications to equal the toxicity of a single application of synthetic pesticides. Because of their perceived/real reduced effectiveness compared to synthetic pesticides they are often improperly mixed or excessively applied by farmers. Both of which quickly closes the gap on synthetics.
