Abstract

A weed-killing and plant-growth inhibiting composition e.g. for defoliation, desiccation, blossom thinning, prolongation of the harvest period and storing propensities comprises a pyridine carboxylic acid or derivatives thereof of the general formula <FORM:0923387/VI/1> wherein X represents O, S, NH or N-alkyl, Y and Z represent halogen atoms and R represents hydrogen, a low molecular alkyl, alkoxyalkyl, hydroxyalkyl, halogen alkyl or alkenyl radical or, if X is O or S, R represents a normal equivalent of a cation in particular of an alkali metal, earth alkali metal or ammonium ion, combined with suitable carriers and distributing agents and/or with organic liquids boiling above 80 DEG C. Specified active ingredients are 2,6-dichloro pyridine-4 carboxylic acid, its methyl ester and amide, 2.6-dichloropyridine-4-carboxylic acid ethyl ester, -n-propylester, -isopropyl ester, -b -chlorethyl ester, -b -methoxyethyl ester, -b -ethoxyethyl ester, -allylester, -methallylester; 2.6 - dichloropyridine - 4 - thiocarboxylic acid-s-methyl ester and -s-butyl ester; 2.6-dichloropyridine-4-carboxylic acid methylamide, ethylamide, isopropylamide, dimethylamide, diethylamide, - b - hydroxyethylamide, g - methoxypropylamide, g - isopropoxypropylamide, allylamide and methallylamide; 2.6 - dibromopyridine - 4 - carboxylic acid ethyl ester, b -chlorethylester, b -methoxyethyl ester, b -ethoxyethyl ester, amide and diethylamide; 2.6-di-iodopyridine-4-carboxylic acid amide and 2.6-difluoropyridine-4-carboxylic acid amide, the sodium, potassium, calcium and ammonium salts of 2.6-dichloropyridine - 4 - carboxylic acid, 2.6 - dibromopyridine - 4 - carboxylic acid, 2.6 - di - iodopyridine - 4 - carboxylic acid and 2.6 - difluoropyridine-4-carboxylic acid and the free acids themselves. The composition may be made in the form of emulsions, suspensions, pastes, dusts or granules with the usual carriers. Other substances having bactericidal or fungicidal properties and substances which influence plant growth e.g. 3-amino-1-2-4-triazole and salts of alpha alpha dichloropropionic acids and fertilizers e.g. ammonium sulphate or urea may also be included.
