Abstract

1,237,486. Defoliants containing dipyridylium complexes. GREAT LAKES CORP. 23 Oct., 1969 [23 Oct., 1968], No. 52035/69. Heading C1B. [Also in Divisions A5 and C2] Defoliating compositions, particularly applicable to cotton plants, contain as active ingredient a compound of the formula in which the halogen of Hal 3 is chlorine, iodine and/or bromine, R and R1 are optionally substituted alkyl C 1-8 radicals, the pyridyl groups may be additionally substituted by optionally substituted alkyl C 1-8 radicals and when the dipyridylium group is 2,21-dipyridylium R and R1 can also together form an optionally substituted C 1-4 alkylene radical, together with an inert carrier e.g. water, gasoline, kerosene or light oil. Preferred compounds are the dibromine complexes of N,N1-dimethyl-4,41-dipyridylium dibromide (Paraquat) and of N,N1-ethylene-2,21– dipyridylium dibromide (Diquat).
