>>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.

In addition to the above criteria, it would be beneficial to include in the consideration the: 

1. Soil residue amounts and activity for both types
2. Products and their toxicity from the break-down of both types
3. Residue in food for both types and the corresponding toxicity to humans.
