Ars Technica reports on a study which, upon examining the environmental impact of six common pesticides, found that an organic mineral oil intended to smother aphids was the worst of all tested, and the other tested organic pesticide rated fourth of the six:
We found that in addition to reduced efficacy against aphids compared to novel synthetic insecticides, organic approved insecticides had a similar or even greater negative impact on several natural enemy species in lab studies, were more detrimental to biological control organisms in field experiments, and had higher Environmental Impact Quotients at field use rates.
