IPC: C07D493/08

Abstract: Plant response e.g. root stimulant, compositions comprise at least one salt of a strong mineral acid with ammonia an alkyl amine, an alkanol amine or a mixed alkyl-alkanol amine, and at least one water-soluble compound the anion portion of which is of exo-cis configuration and conforms to the formula:  <FORM:0761545/I/1> in which R represents a primary or secondary alkyl radical having 1 to 8 carbon atoms.  The mineral salts which may be in neutral or acid form are those of sulphuric, hydrochloric, nitric and phosphoric acids and specified salts are ammonium dihydrogen phosphate and ammonium monohydrogen phosphate; ammonium, mono-, di-, and trialkylammonium sulphates and acid sulphates, chlorides, nitrates, phosphates and acid phosphates having from 1 to 4 carbon atoms in each alkyl radical; mono-, di-, and trialkylammonium sulphates and acid sulphates, chloride, nitrates, phosphates and acid phosphates having from 2 to 3 carbon atoms in each alkanol radical; mixed alkylalkanolammonium sulphates, and acid sulphates, chlorides, nitrates and phosphates which are N-substituted by 2 to 3 radicals of the type and carbon content indicated; the proportion of the mineral salt to the water-soluble compound may be from 1 : 10 to 20 : 1 particularly from 1 : 2 to 5 : 1 but if substantial fertilization of the soil is required it may be 100 : 1 or greater.  The composition may be admixed with liquid and solid carriers such as water, oil, clay e.g.  Fuller's earth, pyrophyllite, talc, bentonite, kieselguhr, diatomaceous earth, commercial clays such as Homer Clay and Tripoli, non-clay carriers e.g. sulphur, volcanic ash, calcium carbonate, lime, by-product lignin, lignocellulose, flour such as wood, walnut shell, wheat, soybean, potato, cotton seed.  The mixture may be dissolved, dispersed, suspended or emulsified in the liquid carriers and used as a spray, specified emulsifying or dispersing agents being fatty alcohol sulphates, such as sodium laurylsulphate, aliphatic or aromatic sulphonates, such as sulphonated castor oil or the various alkarylsulphonates (such as the sodium salt of monosulphonated nonyl naphthalene), and nonionic types such as the high molecular weight alkyl polyglycolethers or analogous thioethers, such as the decyl, dodecyl, and tetradecyl polyglycolethers and thioethers containing from 25 to 75 carbon atoms.  There may also be added wetting agents fungicides, insecticides, bactericides and humectants examples of the latter being glycerine, diethylene glycol, ethylene glycol, polyethylene glycols generally, and water-soluble sugars and sugar-containing mixtures, such as glucose, fructose, galactose, mannose, arabinose, xylose, sucrose, maltose, lactose, raffinose, trehalose, dextrins such as white dextrin, canary dextrin, British gum, &c., honey, molasses, maple syrup, maple sugar, and starch syrups such as corn syrup.ALSO:A herbicidal, defoliant or like plant response composition comprises at least one salt of a strong mineral acid with ammonia, an alkyl amine, an alkanol amine or a mixed alkyl-alkanol amine, and at least one water-soluble compound the anion portion of which is of exo-cis configuration and comforms to the formula:- <FORM:0761545/VI/1> in which R represent a primary or secondary alkyl radical having 1 to 8 carbon atoms.  The mineral salts which may be in neutral or acid form are those of sulphuric, hydrochloric, nitric and phosphoric acids and specified salts are ammonium dihydrogen phosphate and ammonium monohydrogen phosphate; ammonium, mono-, di-, and trialkylammonium sulphates and acid sulphates, chlorides, nitrates, phosphates and acid phosphates having from 1 to 4 carbon atoms in each alkyl radical; mono-, di-, and trialkylammonium sulphates and acid sulphates, chloride, nittrates, phosphates and acid phosphates having from 2 to 3 carbon atoms in each alkanol radical; mixed alkylalkanolammonium sulphates, and acid sulphates, chlorides, nitrates and phosphates which are N-substituted by 2 to 3 radicals of the type and carbon content indicated; the proportion of mineral salt to the water-soluble compound may be from 1:10 to 20:1 particularly from 1:2 to 5:1 but if substantial fertilization of the soil is required it may be 100:1 or greater. The composition may be admixed with solid and liquid carriers and used in the form of dust or sprays obtained by dissolving, suspending, dispersing or emulsifying in liquid carriers.  Wetting agents, humecants, fungicides, insecticides, bactericides and other active ingredients and plant response agents may be present.
