[A Specification was laid open to inspection under Sect. 91 of the Acts, July 30, 1938.] [Classes 6 (ii), 58 and 111] A preparation for stimulating plant growth comprises an excipient containing a mixture of one or more substances selected from each of the following classes of hetero-auxines viz:- (A) compounds in which a hydrogen atom of an indol nucleus is replaced by a carboxyl radical or a higher homologue, (B) compounds in which a hydrogen atom of a nucleus formed by at least two condensed aromatic rings is replaced by a carboxyl or a higher homologue. Each class also includes the salts, esters, and nitriles of the respective substances and the homologues in which hydrogen atoms of the nucleus are replaced by aliphatic radicals. Examples of class A are # indolyl acetic acid, its homologues and esters etc.; of class B, naphthalene acetic acid, anthracene acetic acid and their derivatives. Examples of excipients are lanolin, alcohol, soaps, fatty oils, hydrocarbons, pulverulent colloidal materials &c. and the product may be adapted for use in dissolved, pasty or powdered state. Auxiliary ingredients may be present, such as carotin, amino-acids, bios substances, vulpinic acid, trytophane, indol dextrin, sugars, also fungicides especially boron compounds. Cuttings may be treated by immersion in a solution of the preparation, or the latter may be mixed with the medium in which the plant is planted. Graftings may be covered with the preparation in paste or powder form. Specification 509,282 is referred to. The Specification as open to inspection under Sect. 91 describes the use of auxines in general with an excipient. This subject-matter does not appear in the Specification as accepted. |
