Definitions
- the present invention relates to combinations of crop protection active ingredients with such polymeric anionic auxiliaries which enable controlled release of an active ingredient.
- the combinations are able to increase culture selectivities and prevent antagonisms and give particularly good results with herbicides, in particular with mixtures of herbicides with growth regulators and safeners.
- split application or an overdose of the antagonized active ingredient was recommended in the case of an antagonistic reduction.
- a split application can often also be used, alternatively there is the possibility of underdosing.
- all of these approaches are unattractive and uneconomical for various reasons.
- the active substance formulation must be applied at least twice; that is time and labor intensive. If an active ingredient is overdosed, additional costs are incurred. In the event of an underdosage, there is a risk of reduced yield due to insufficient control of harmful organisms.
- US 5,428,000 discloses active ingredient compositions which have a herbicide for broad-leaved weeds and a herbicide for narrow-leaved weeds.
- the herbicide for narrow-leaf weeds is charge-neutral
- the herbicide for broad-leaf weeds is anionic in nature and is present in combination with a hydrophilic polymer, which is a copolymer formed from an ammonium-containing compound and a non-ammonium-containing compound.
- the ammonium-containing compound is generally derived from aromatic and non-aromatic nitrogen heterocycles, ammonium derivatives of acrylic acid and benzylammonium compounds.
- the polymers are therefore exclusively polymers which do not contain the quaternary nitrogen atom in the main polymer chain.
- the hydrophilic polymers used are exclusively copolymers of the type shown above. Sethoxydim, alloxidim, fluazifop, quizalofop or fenoxaprop are used as herbicides for narrow-leaf weeds, for broad-leaf weeds the use of bentazone, imazaquin, acifluorfen, fomesafen, chlorimuron, imazethapyr, thifensulfuron and 2,4-D is described.
- This object is achieved by a combination of at least one agrochemical active substance having cationic functional groups, in particular a herbicide, with an anionic polymer with the formation of electrostatic interaction between these components for the controlled release of this active substance. It has been found that problems such as scarce selectivity or inadequate compatibility with culture or reduced activity caused by antagonism can be avoided by combining certain anionic polymers with one or more agrochemical active ingredients.
- Another object of the present invention is the application of the combination according to the invention for controlling unwanted harmful organisms, in particular undesired grasses and weeds.
- polymer in the present invention encompasses both oligomers and polymers as well as homopolymers and copolymers or oligomers of the corresponding monomers, ie molecules with a low degree of polymerization as well as those with a high degree of polymerization.
- the molecular weights MN of the compounds which can be used according to the invention as polymers are at least 500.
- the agrochemical active ingredient enters into an attractive, reversible intermolecular interaction with the oligomer or polymer in whole or in part. These interactions are electrostatic interactions.
- the agrochemical active ingredient can be an active ingredient that has partial selectivity.
- an active substance which has an antagonistic effect in an intended mixture of active substances can also be brought into interaction with the polymer. Two or more active substances in a mixture of active substances can also be incorporated into such an interaction.
- the anionic polymers used according to the invention can also be molecules which are surface-active. Due to their physicochemical properties, they can be dispersed, emulsified or dissolved in water and / or organic solvents.
- the polymers can preferably be dissolved, the preferred solvents being polar protic and polar are aprotic organic solvents and water. It is usually preferred if the polymers dissolve in water.
- Polymers suitable for the combinations according to the invention preferably have the property of penetrating the harmful organism only slowly or not at all, which generally occurs, for example, via the leaf or the root.
- the absorption or penetration rate of the polymers used according to the invention is between ⁇ 0.01% and 80%, preferably well below 50% in 24 hours.
- the polymers used according to the invention have negatively charged functional groups.
- the average molecular weight M N of the polymers used according to the invention is from> 500, preferably from about 1,000 to 1,000,000.

- Modified natural polymers for example oligo- and polypeptides and oligo- and polysaccharides, are also suitable.
- Suitable negatively charged functional groups are carboxylate (COO ⁇ ), sulfonate (SO 3 ⁇ ), sulfate (OS0 3 e ), phosphonate groups (P (O) ORO ⁇ , P (O) 0 2 2 " ) and phosphate groups ( OP (0) O 2 2 ⁇ , OP (O) ORO ⁇ ).

- suitable anionic polymers are known to a person skilled in the art. Generally, commercially available products will be used.
- Agrochemical active substances suitable for the present invention have functional groups, are positively charged or carry a positive partial charge and can be converted into cationic functions.
- the active ingredients can be present as cations before formulation. However, it is also possible that these active ingredients are only converted into cations during the formulation or preparation of the so-called tank mixture, for example by protonation or by abstraction of groups or counterions, during these processes.
- Suitable cationic active ingredients for use in the combinations according to the invention are those which belong to the group of herbicides, fungicides, insecticides, growth regulators, safeners, acaricides, molluscicides and nematicides.
