CR-91

According to Samantha Carter and General Landry, CR-91 is used as a neurotoxin to eliminate any kind of organism that would deem hazardous to the security of Earth, the SGC, or any offworld base. It was also stated by Doctor Lee that the neurotoxin is hazardous to any humans as well.

Deployment of CR-91 would most likely be dropped from planetary orbit by an X-304.
