Inventor: ALLEN WILLIAM WATSON
IPC: C07D249/14
Filed: 1953-09-04
Abstract: A plant-growth regulating composition capable depending on the amount of active ingredients, of modifying plant-gowth by root stimulation or inhibition, defoliation, production of albinism or complete eradication of plants, comprises 3-amino-1 : 2 : 4-triazole together with a wetting agent and a compatible diluent.  The diluent may be clay, chalk or talc or water and the compositions may contain penetrants, sequestrants, oils, minerals, fertilizers, trace elements or other hormones.  Hormones specified are 2 : 4-dichlorophenoxyacetic acid, 2 : 4 : 5-trichlorophenoxyacetic acid, 2-methyl-, 4-chlorophenoxyacetic acids, and their salts, esters and amides.  The oils employed may include light motor grade and diesel oils, the sequestrants may be hexametaphosphates, and the penetrants may be mahogany soaps. The wetting agents may be sulphonated vegetable oils such as corn, castor, peanut or soybean, sodium lauryl sulphate, sodium cetyl sulphate, sodium alkyl naphthalene sulphate, polyoxyalkalene derivatives of sorbitan monolaurate, polyalkylene ether alcohol and polyethylene glycols of molecular weight of 1500 or more. Examples of compositions exerting phytotoxic action on plants refer to the use of 1 to 30 parts of 3-amino-1 : 2 : 4-triazole with 10 to 100 parts of wetting agents made up to a 1000 parts with water, and to 1 part of 3-amino-1 : 2 : 4-triazole with 1 part of wetting agent of which is mixed with 988 parts of water. Specifications 598,072, 598,104, 598,105, 673,779, 688,056 [all in Group VI] and 779,636 also is referred to.ALSO:A plant-growth regulating composition capable depending on the amount of active ingredients, of modifying plant-growth by root stimulation or inhibition, defoliation, production of albinism or complete eradication of plants, comprises 3 - amino - 1:2:4-triazole together with a wetting agent and a compatible diluent.
