The formulations according to the invention are suitable for the field of plant protection.
Claims28
Process for producing an aqueous, solvent-free formulation, comprising melting at least one active agrochemical ingredient a) having a melting temperature range between 50° C. and 80° C. in a first step, then the melt is added to water while stirring, the water containing at least one ionic and/or nonionic dispersant b), and the mixture is cooled below the melting point of the active ingredient in a second step.
Solvent-free, water-dispersible technical concentrate (TCs) comprising
- one or more active ingredients a) having a melting temperature range between 50 and 80° C.,
- one or more anionic emulsifiers b1),
- one or more nonionic emulsifiers b2),
- at least one or more than one carrier material c1) and
- at least one filler c2).
Solvent-free, water-dispersible suspension concentrates (SCs) comprising
- one or more active ingredients a) having a melting temperature range between 50 and 80° C.,
- one or more anionic emulsifiers b1),
- one or more nonionic emulsifiers b2),
- a carrier material c1) and
- at least one or more than one thickener d).
