Abstract
IN connexion with an investigation into the mode of action of certain diquaternary salts of 2,2′-, 2,4′-, and 4,4′-dipyridyl as herbicides1 the behaviour of a number of dipyridyl diquaternary salts on reduction has been examined.

The herbicidal activity of certain quaternary salts of 2,2′-dipyridyl is the subject of U.K. Patent Specification 785,732 ; U.K. Patent Specifications 813,531 and 813,532 disclose similar activity in the quaternary salts of 4,4′-dipyridyl. The activity of 2,4′-dipyridyl salts has not hitherto been disclosed.
