Abstract

Weed-killing granules, suitable for aerial distribution comprise a a carrier medium having a hormone substance intimately incorporated therewith formed into granules of a size such that they will pass through a 10 mesh B.S.S. sieve and will be retained on a 60 mesh B.S.S. sieve, the hormone constituting at least 0.1 per cent of the composition and being sufficient to render the composition herbicidal. Hormones specified are 2, 4-dichlorophenoxyacetic acid amines and sodium salts, 4 chloro-2-methylphenoxyacetic acid and 2, 4, 5 tri-chlorophenoxyacetic acid and their esters. The carrier may be clay, gypsum, lime or chalk or a fertiliser such as superphosphate especially fines from a granulation process and nitrogen or potash fertilizers. The hormones may be incorporated with the carrier substance by spraying a solution of the hormone on the carrier during granulation or mixing with the carrier prior to granulation. Specification 573,929, 574,274, 598,104, 598,105, 609,137, [all in Group VI], and 689,819 are referred to.ALSO:Weed-killing granules, suitable for aerial distribution comprise a carrier medium having a hormone substance intimately incorporated therewith formed into granules of a size such that they will pass through a 10 mesh B.S.S. sieve and will be retained on a 60 mesh B.S.S. sieve, the hormone constituting at least 0.1 per cent of the composition and being sufficient to render the composition herbicidal.
