Agent Orange is a herbicide and defoliant chemical. It is widely known for its use by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand,[1] during the Vietnam War from 1961 to 1971.[2] It was a mixture of equal parts of two herbicides, 2,4,5-T and 2,4-D. The chemical damaged the health of people who came in in contact with it as well as extensively contaminated the environment.

Crossbow is a post emergent specialty herbicide that targets unwanted trees, brush, and woody plants, such as, blackberries, sumac, and poison oak. The active ingredient in Crossbow is triclopyr and 2,4-D ester, which will kill undesirable plants but will not harm desirable lawn grasses and turf.

With the "judicious" application of these two products one could put the entire earth in "Chemical Fallow."  aye...the wonderful world of chemistry.  Gary Crum
