TX Anticrop Agent & Project 112

From January 1962-October 1969, Rocky Mountain Arsenal “grew, purified and biodemilitarized” plant pathogen wheat stem rust [Puccinia graminis, var. tritici] for the Air Force. TX-treated grain was grown at the Arsenal from 1962-1968 in Sections 23-26. Unprocessed TX was also transported from Beale AFB for purification, storage, and disposal.

The following docs outline these activities at RMA:

The point is that there is still 90.00 pounds of TX located in the northern portion of the Arsenal. Considering the trouble and money involved in the demil of TX it would seem stupid to ignore that agent. If the government decided to leave it there it would appear that this should be questioned due to the cost already expended and the amount of effort that had been expended. If the government were to say there was no danger with the TX then why was such effort then take to contain the already dead agent?

Question for researchers: Was the visit by Japanese scientists to RMA connected in any way to Project 112, which also field tested wheat rust in Okinawa?

Summary Documents

When researching the history of Rocky Mountain Arsenal several years ago, I requested and received under FOIA The Summary of Major Events and Problems and The Summary History of Chemical Corps Activities. Both sets of reports reveal a rich history of the Chemical Corps weapons complex, which include details of field and logistical exercises, facilities, the Tripartite conferees (U.S. Canada, and the UK), common work in chemical, biological, and radiological (CBR) warfare and genetic research.

The documents also chronicle the Corps’ involvement in weapons R & D and classified projects related to CBR warfare post World War II through the Cold War. The full extent of Chemical Corps projects remains unknown; looking at the dates of documents below and descriptions of projects, I speculate more than a few projects were part of Project ARTICHOKE,  MKULTRA, and MKNAOMI, and/or other projects heretofore unidentified. The Chemical Corps, an agency created out of the War Gas Investigations research unit in 1917, was dissolved August 1, 1962. I am not certain if these reports are part of RG 175.

By gathering this set together for the first time,* it is my hope researchers will be encouraged to submit their own Freedom of Information Act requests on obscure projects and  programs mentioned throughout the reports in an attempt to “detoxify the sources of our scholarship.” **
