They're primarily a seed company. Most of the products they have in the pipeline are based on generating resistances to various crop diseases/insects. They try to do this in a variety of ways. GMOs are relatively more expensive then breeding, so that generally tends to be the method of last resort when they can't find a natural resistance to breed in.
The scientists I also talked to mentioned a 30% overall reduction in herbicide used with round up ready plants. That could definitely be propaganda, and if anyone has any hard facts I can ask anonymously at our weekly meeting and hopefully get answers from our executive team.
