摘要:

摘要:
When herbicides are applied, surfactants can affect the wettability of leaves of the plants and the effectiveness of the herbicides. According to the invention, a particular intensification of action is achieved when surfactants from the group comprising the C.sub.10 -C.sub.18 -alkyl polyglycol ether sulfates and their physiologically acceptable salts together with leaf-acting selective herbicides or the leaf-acting non-selective herbicides glyphosate, paraquat or diquat are applied.
摘要:
Novel water-dispersible granules of plant protection agents, in particular of herbicides and growth regulators, are obtained when a dispersion or solution in water of 10 to 90% by weight of active substance with 10 to 90% by weight of solid wetting agents from the group containing of alkanesulfonates, alkylsulfonates, alkylnaphthalenesulfonates, alkylbenzenesulfonates, long-chain olefinsulfonates, alkyl polyol ether sulfonates, alkyl ether sulfates, alkyl ether phosphates, alkylsulfosuccinic monoesters, fatty acid isethionates and fatty acid N-methyltaurides, or of an ammonium salt, or of a mixture of an ammonium salt and one or more of the above solid wetting agents, and 0 to 50% by weight of customary formulation agents is prepared and the dispersion or solution is granulated using the cocurrent or counter-current process.
摘要:
The invention relates to water-emulsifiable granules of crop protection agents composed of the pesticidal active substance in liquid or dissolved form and an at least partially water-soluble shell-forming structural material, to the use of these granules as novel, advantageous formulations of crop protection agents, and to processes for their preparation. It furthermore relates to the general use of polyvinyl alcohols as shell-forming structural materials in the preparation of water-emulsifiable granules which contain organic compounds dissolved in a high-boiling solvent or solvent mixture.
摘要:
The invention relates to defoamed aqueous solutions of surfactants and to low-foam concentrated liquid preparations of plant protection agents, which contain sulfato- or sulfonato-containing surfactants as wetting agents and surfactants from the group comprising the perfluoro(C.sub.6 -C.sub.18)alkylphosphinic acids and/or -alkylphosphonic acids and/or their salts, as defoamer.
