Title: Improvements in and relating to plant growth influencing compositions
IPC: C07D251/18
Filed: 1955-08-15
Abstract: A composition for influencing the growth of plants, especially for killing weeds, comprises an s-triazine derivative of the general formula: <FORM:0814949/I/1> wherein X represents a hydrocarbon radical bound by way of O, S or NH or two hydrocarbon radicals bound by way of N, the hydrocarbon radical(s) possibly being substituted by chlorine or hydroxyl groups, and Y represents hydrogen, chlorine, the mercapto group or a hydrocarbon radical buond either direct or by way of O or S, the hydrocarbon radical possibly being substituted by chlorine or hydroxyl groups, and wherein any aromatic rings in the radicals X and Y should not be bound direct to the triazine ring or to the bridging atom, and, as a carrier, (a) a water-insoluble pulverulant solid or (b) an organic solvent boiling above 150 DEG C., or (c) an emulsifying agent together with a water-insoluble pulverulent solid or an organic solvent.  The carrier may itself by phytotoxic e.g. high boiling mineral oil factions or chlorohydrocarbons, other specified carriers which are inert are cyclohexanol, kerosene, tetrahydronaphthalene, alkylated naphthalene mineral and vegetable oils, talcum, diatomaceous earth, kaolin, bentonite calcium carbonate, tricalcium phosphate, sawdust, powdered cork, charcoal.  Dispersing and wetting agents, protective colloids and substances to improve adhesive properties such as fatty acids glue, casein and alginates, fungicides, bactericides and fertilizers may also be incorporated.  Specified active ingredients are 2-chloro-4 : 6-dimethoxy-s-triazine, 2 : 4-dichloro-6-ethylamino-s-trizine, 2 : 4-dichloro-6-n-propylamino-s-triazine, 2 : 4-dichloro-6-n-butylamino-s-triazine and 2 : 4-dichloro-6-allylamino-s-triazine, 2 : 4-dichloro-6-methylamino-s-triazine.ALSO:A composition for influencing the growth of plants, especially for killing weeds, comprises an s-triazine derivative of the general formula <FORM:0814949/VI/1> wherein X represents a hydrocarbon radical bound by way of O, S or NH or two hydrocarbon radicals bound by way of N, the hydrocarbon radical(s) possibly being substituted by chlorine or hydroxyl groups, and Y represents hydrogen, chlorine, the mercapto group or a hydrocarbon radical bound either direct or by way of O or S, the hydrocarbon radical possibly being substituted by chlorine or hydroxyl groups, and wherein any aromatic rings in the radicals X and Y should not be bound direct to the triazine ring or to the bridging atom, and, as a carrier, (a) a water-insoluble pulverulent solid or (b) an organic solvent boiling above 150 DEG  C., or (c) an emulsifying agent together with a water-insoluble pulverulent solid or an organic solvent.
