Inventory of observed unexpected environmental effects of genetically modified crops [PDF]

In general, it can be concluded that very few clearly unexpected effects were observed during the large scale post-release growing of herbicide-tolerant crops and Bt crops.

Experiences with entomopathogenic nematodes for the control of overwintering codling moth larvae in Germany [PDF]

, 2008
Entomopathogenic nematodes were tested for their potential as tool in resistance management of codling moth Cydia pomonella L. in organic fruit growing. In two field tests, the adults emerging from stems treated with nematodes were monitored.

The payoffs to agricultural biotechnology: an assessment of the evidence [PDF]

Transgenic crops are relatively new technologies being adopted rapidly in the United States and in a few other countries. The economic impacts of these technologies have, thus far, been estimated in a piecemeal fashion.
