Definitions

  • the present application relates to a new process for the preparation of standard wax mixtures containing agrochemical active ingredients.
  • agrochemical active ingredients are applied in the form of granules in aquatic crops, for example in water rice fields, there is often the danger that the granulate particles will sink from the water surface, the active ingredient will be detached and there will be an undesirably high concentration.
  • granules have already been proposed which are buoyant and which release the active substances contained in the concentration required in each case from the water surface (cf. JP-A 88-35504 and JP-A 93-155703). It is already known to produce such floating granules by treating agrochemical active ingredients with a wax melt, then cooling, crushing the resulting solid product and, after mixing with conventional additives, applying it to suitable carrier materials.
  • a disadvantage of this process is that the wax standard mixture obtained after the melt has cooled is difficult to comminute and the active ingredient particles are only incompletely enveloped by a wax layer after grinding.
  • Wax layer are coated. Above all, it is unexpected that such wax premixes can only be obtained by the process according to the invention if the stirring tools in the mixer are sharp-edged.
  • the method according to the invention is characterized by a number of advantages.
  • the required components are easily accessible and also available in large quantities. Furthermore, the method can be carried out in conventional devices with little effort. In addition, the wax premixes obtained can be processed directly; Grinding is not necessary.
  • Agrochemical active ingredients are to be understood here as fungicides, bactericides, insecticides, acaricides, nematicides, herbicides and plant growth regulators.
  • fungicides are:
  • Carbendazim carboxin, quinomethionate (quinomethionate), chlorothalonil, cimoxanil, cyproconazole, carpropamide,
  • Fenpropimorph fluazinam, fludioxonil, fluquinconazole, flusilazole, flusulfamide,
  • Flutolanil Flutriafol, Fosetyl aluminum, Fhthalide, Fuberidazol, Furalaxyl, Guazatine,
  • Penconazole pencycuron, probenazole, prochloraz, procymidone, propiconazole, propineb, pyrifenox, pyrimethanil,
  • Tebuconazole Tebuconazole, tecloftalam, tecnazen, tetraconazole, thiabendazole, thicyofen, thiophanat-methyl, thiram, tolylfluanid, triadimefon, triadimenol, triazoxid, trichlaid, tricyclazole, tridemorph, triflumizol, trifazolin, trifazolin, trifazolin, trifazorin, trifazorin,
  • insecticides examples include acaricides and nematicides.
  • Fenamiphos fenazaquin, fenbutatin oxide, fenitrothion, fenobucarb, fenothiocarb,
  • Fenoxycarb Fenpropathnn, Fenpyrad, Fenpyroximat, Fenthion, Fenvalerate,
  • Fipronil fluazuron, flucycloxuron, flufenoxuron, flufenprox, fluvalinate,

  • Mecarbam Methiocarb, Methomyl, Metolcarb, Milbemectin, Moxidectin,
  • herbicides examples are:
  • plant growth regulators are chlormequat-methyl and
  • oils customary for the production of agrochemicals
  • Rapeseed oil sunflower oil, soybean oil, cottonseed oil, olive oil, castor oil and white oil are preferred.
  • Suitable waxes for carrying out the process according to the invention are all substances with a wax-like consistency that are suitable for the production of agrochemicals and have a softening point between 80 ° C. and 120 ° C. exhibit.
  • Montan waxes such as paraffin wax, polyethylene waxes with a molecular weight of up to about 10,000 and modified polyethylene waxes, such as, for example, sulfonylated waxes, furthermore esters of montan wax acids and also partially saponified esters of montan wax acids are preferably usable.
  • Carrier materials for example natural rock powders such as kaolins, alumina, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and also synthetic rock powders such as highly disperse silica, aluminum oxide and silicates are preferred.
  • All customary mixers which are suitable for producing wax premixes can be used to carry out the process according to the invention.
  • the prerequisite is that the mixers can be heated and contain sharp-edged stirring devices.
  • Mixers with sword-like ground or sharp-sided stirring devices that are flattened on one side are preferred.
  • high stirring speeds must be maintained, preferably one works at speeds at which the outer ends of the stirring devices move at a speed of at least 18 m / sec, preferably between 18 and 40 / sec.
  • temperatures can be varied within a certain range when carrying out the method according to the invention. In general, temperatures between 10 ° C and 80 ° C, preferably between 20 ° C and 50 ° C.
  • the process according to the invention is generally carried out under atmospheric pressure. However, it is also possible to work under increased or reduced pressure. Both the size of the agrochemical active ingredient and the size of the wax particles can be varied within a certain range when carrying out the process according to the invention. It is preferable to use active ingredient particles whose diameter is between 20 and 180 ⁇ and wax particles whose diameter is between 4 and 150 ⁇ .
  • the proportions in which the individual components are used in carrying out the process according to the invention can also be varied within a certain range.
  • the procedure is such that 1 part by weight of agrochemical active ingredient
  • one or more solid, agrochemical active ingredients in finely divided form are mixed with at least one vegetable or mineral oil in the mixing device, then wax is added in finely divided form, homogenized with high stirring speed and optionally then mixed with additives and homogenized again at high stirring speed.
  • These components are preferably used in ground form so that both wax and agrochemical active ingredients and optionally also additives are present in a sufficiently fine-particle form. Will be after coating the agrochemical
  • the wax premixes which can be produced by the process according to the invention are finely divided, free-flowing products in which the agrochemical active ingredient articles are completely enveloped by a closed wax layer.
  • wax premixes which can be prepared according to the invention can be prepared by customary methods
  • granules which can float in water can be produced by applying wax premixes which can be prepared according to the invention, if appropriate after addition of further additives, such as adhesives and / or surface-active substances, to low-density carrier materials.
  • further additives such as adhesives and / or surface-active substances
  • products which can be produced according to the invention directly for the treatment of plants.
  • wax premixes which can be produced according to the invention and the agrochemical compositions which can be obtained therefrom are distinguished by the fact that, when used,
  • Plant treatment the active ingredients contained are released evenly and over a longer period of time.
  • a wax premix is obtained in this way from active ingredient particles partially coated with wax and separate wax particles.
  • the suspension is stirred vigorously at 110 ° C. for 10 minutes and then, with further stirring while the mixer is fully stirring,
  • a wax premix consisting of agglomerated particles is obtained in this way. About 10 percent by weight of the cyclosulfamuron contained has decomposed.
