Title: Improvements in or relating to plant-growth regulating compositions
Inventor: ALLEN WILLIAM WATSON
IPC: C07D249/14
Filed: 1953-09-08
Abstract: A plant-growth regulating composition capable, depending upon the portion of active ingredient, of root stimulation or inhibition, defoliation, production of albinism and complete suppression of plants, consists of 3-amino-1 : 2 : 4-triazole together with a different substance capable of modifying plant growth, together with a carrier or diluent which may be clay, talc or chalk or water.  The compositions may contain wetting agents such as sulphonated vegetable oils for example corn, castor, peanut or soybean oils, sodium lauryl or cetyl sulphate, sodium alkyl naphthalene sulphate, polyalkylene derivatives of sorbitan monolaurate, polyalkylene ether alcohols, and polyethylene glycols of molecular weight of 1500 or more, penetrants such as mahogany soaps, sequestrants such as hexametaphosphates, oils such as light grade motor or diesel oils, minerals such as fertilizers, and trace elements.  Substances capable of modifying plant-growth which are referred include 2 : 4-dichlorophenoxyacetic acid, 2 : 4 : 5-trichlorophenoxyacetic acid, 2-methyl-4-chlorophenoxyacetic acid and their salts, esters and amides.  Examples refer to (1) a 4 to 1 by weight mixture of the sodium salt of 2 : 4-dichlorophenoxyacetic acid and aminotriazole which may be diluted with water for a spray application, (2) the triethanolamine salt of 2-methyl-4-chlorophenoxyacetic acid, aminotriazole and water in the proportions of 3 pounds to 1 pound to 1 gallon, (3) disodium 3 : 6-endoxohexa hydrophthalate and aminotriazole in the proportion of 6 to 1 which composition may be mixed with water for defoliation, (4) sodium chlorate and aminotriazole in proportions of 6 to 1 which may be diluted with 10 gallons of water for application to an acre of cotton thereby effecting 90 per cent defoliation.  Specification 779,635 also is referred to.ALSO:A plant-growth regulating composition capable, depending upon the portion of active ingredient, of root stimulation or inhibition, defoliation, production of albinism and complete suppression of plants, consists of 3 - amino - 1 : 2 : 4 - triazole together with a different substance capable of modifying plant growth, together with a carrier or diluent which may be clay, talc or chalk or water.
