Importance of Adding Genes:
1. To provide improved effectiveness across the various caterpillar species. Different genes have strengths on certain species.
2. To manage resistance and preserve the technology.
Have you ever considered the significance if resistance should occur to the Bt gene(s)? We were living on the edge with a single gene.
