HERBICIDAL AND PLANT GROWTH REGULANT COMPOSITIONS AND THE USE THEREOF

摘要

Glyphosate formulations which are effective even when employed at dosages below the dosage currently recommended for post-emergent herbicidal or plant growth regulant use are described. They are formulated as water solutions or powders or granules from (a) one or more agriculturally acceptable salts of glyphosate; (b) at least one water-soluble long chain aliphatic hydrocarbyl dimethyl amine oxide in which the hydrocarbyl group is a linear or substantially linear saturated or olefinically unsaturated aliphatic group having in the range of 8 to 22 carbon atoms; (c) at least one water-soluble straight or branched chain saturated or olefinically unsaturated alcohol ethoxylate having in the range of 8 to 24 carbon atoms in the aliphatic hydrocarbyl group and in the range of 2 to 50 ethyleneoxy groups per molecule, and (d) at least one water-soluble or water-dispersible N-hydrocarbyl pyridinium halide having up to 24 carbon atoms in the molecule, and wherein (i) the hydrocarbyl group attached to the nitrogen atom of the heterocyclic aromatic ring of the pyridinium nucleus is a saturated or olefinically unsaturated aliphatic hydrocarbyl group having in the range of 4 to 18 carbon atoms, and (ii) the ring carbon atoms of the pyridinium nucleus itself are either unsubstituted or one or more of such ring carbon atoms are substituted with a short chain alkyl group of up to 4 carbon atoms, or a solution or suspension thereof.
