Description
Vynález sa týká výroby herbicídneho prostriedku.The invention relates to the production of a herbicidal composition.
Podlá doslal' známých postupov a zaužívaného sposobu výroby sa kombinovaný herbicídny prostriedok na báze 2-metyl-4-chlórfenoxyoctovej kyseliny, 2-chlór-6-etylamíno-4-izopropylamíno-l,3,5-triazínu a 2-chlór-4,6-bis-etylamíno-triazínu vyrábal finalizáciou jednotlivých účinných látok, ktoré boli vo formě jemne rozomletých práškov homogenizované, po doplnění anorganických plnidiel požadovanej jemnosti finálně upravené pomocou přísad a povrchovoaktívnych látok.According to known methods and conventional production methods, the combination herbicidal composition based on 2-methyl-4-chlorophenoxyacetic acid, 2-chloro-6-ethylamino-4-isopropylamino-1,3,5-triazine and 2-chloro-4, 6-bis-ethylamino-triazine was produced by the finalization of the individual active ingredients, which were homogenized in the form of finely divided powders, after the inorganic fillers of the desired fineness were finally treated with additives and surfactants.
Finalizáciou sa získal jemný prášok, obsahujúci celkove 50 % hmot. účinných látok. Používá sa po roztriedení vo vodě vo formě postreku na ničenie burín na nepol1nohospodárskej pode, najma na železničných tratiach, prekladištiach a manipulačných plochách.Finalization gave a fine powder containing a total of 50 wt. of active substances. The sorting is used in water in a spray for controlling weeds in nepol 1-agricultural land, especially on railway lines, transshipment and handling areas.
Nevýhodou doposial' používaného postupu je možnost získania kombinovaného herbtcídneho prostriedku len vo formě práškového produktu.A disadvantage of the method used so far is the possibility of obtaining the combined herbicidal composition only in the form of a powdered product.
Zistili sme, že kombinovaný herbicídny prípravok na báze 2 metyl-4-chlórfenoxyoctovej kyseliny, 2-chlór-6-etylamíno-4-izopropylamíno-l,3,5-triazínu a 2-chlór-4,6-bis-etylamíno-triazínu možno vyrobit vo formě vodnej suspenzie.We have found that a combination herbicidal preparation based on 2-methyl-4-chlorophenoxyacetic acid, 2-chloro-6-ethylamino-4-isopropylamino-1,3,5-triazine and 2-chloro-4,6-bis-ethylamino-triazine may be prepared in the form of an aqueous suspension.
Výhoda herbicídneho přípravku vyrobeného vo formě vodnej suspenzie je dobrá homogenita výrobku, dobrá rieditelnosť přípravku, ktorá dává předpoklady rovnomernej aplikácie herbicídneho přípravku. Vodná suspenzia vytvára dobré podmienky ku skladovateínosti přípravku, zjednodušená manipuláciu pri áplikácii.The advantage of the herbicidal formulation made in the form of an aqueous suspension is good product homogeneity, good dilution of the formulation, which provides a prerequisite for uniform application of the herbicidal formulation. The aqueous suspension provides good storage conditions, simplified application handling.
Nová forma kombinovaného herbicídneho přípravku obsahuje účinné látky v pevnej fáze, ktoré sú prostredníctvom povrchovoaktívnych látok a polysacharidu upravené do roztoku vodorozpusnej účinnej látky, pričom sa vytvára stabilná suspenzná forma.The novel form of the combined herbicidal formulation comprises solid phase active ingredients which are rendered into a solution of the water-soluble active ingredient by means of surfactants and polysaccharide, forming a stable suspension form.
Výhodou novej formy kombinovaného pesticídneho přípravku je možnost použitia různorodých účinných látok v jednom výrobku. Použitím takto připraveného herbicídneho přípravku sa zjednoduší aplikácia v poínohospodárstve, kde je možné odstránif následné aplikácie jednotlivých pesticídnych prípravkov. Nová forma kombinovaného pssticídneho přípravku umožňuje úspory povrchovoaktívnych látok a obalov.The advantage of the new form of the combined pesticide preparation is the possibility to use different active substances in one product. The use of the herbicidal composition thus prepared will simplify the application in agriculture, where it is possible to remove the subsequent application of the individual pesticidal compositions. The new form of the combined pssticidal formulation allows for savings in surfactants and packaging.
Selektívny herbicídny prípravok na báze účinných látok 2-metyl-4-chlórfenoxyoctovej kyseliny vo formě soli, 2-chlór-6-etylamíno-4-izopropylamíno-l,3,5-triazínu a 2-chlór-4,6-biis-etylamíno-triazínu sa vyrába podlá predmetu vynálezu vo formě vodnej suspenzie tak, že sa do sodnej alebo draselnej alebo dimetylamínovej soli 2-metyl-4-chlór-fenoxyoctovej kyseliny (MCPA), obsahujúcej 12 až 30 °/o hmot. účinnej látky, přidá za miešania jemne rozomletá účinná látka 2-chlór-4-izopropylamíno-6-etylamíno-l,3,5-triazínu (atrazínj v množstve 10 až 30 % hmot. a ďalej sa přidá 0,5 až 2,5 % hmot. neiónového tenzidu (Slovasol SF), predstavujúceho zmesný kopolymér propylénoxidu a etylénoxidu všeobecného vzorca (C2H4O ) x— ( C3HbO ) 4— (C2H4O) x—H v ktorom polyoxypropylénový reťazec tvoří hydrofóbnu a polyoxyetylénový reťazec hydrofilnú časť molekuly.Selective herbicidal preparation based on 2-methyl-4-chlorophenoxyacetic acid active compounds in the form of salts, 2-chloro-6-ethylamino-4-isopropylamino-1,3,5-triazine and 2-chloro-4,6-bis-ethylamino The triazine is produced according to the invention in the form of an aqueous suspension by adding to the sodium or potassium or dimethylamine salt of 2-methyl-4-chlorophenoxyacetic acid (MCPA) containing from 12 to 30% by weight. of the active compound, add with stirring the finely divided active compound 2-chloro-4-isopropylamino-6-ethylamino-1,3,5-triazine (atrazine in an amount of 10 to 30% by weight) and further add 0.5 to 2.5 % by weight of a nonionic surfactant (Slovasol SF) representing a mixed copolymer of propylene oxide and ethylene oxide of the formula (C2H4O) x - (C3HbO) 4- (C2H4O) x- H wherein the polyoxypropylene chain forms the hydrophobic and polyoxyethylene chains of the hydrophilic portion of the molecule.
Ďalej sa přidá 0,1 až 0,6 % hmot. neiónového emulgátora, vyrobeného exyetyláciou vyšších mastných alkoholov (Slovanik M 640). Do finalizujúceho přípravku sa přidá 5 až 11,5 % hmot. etylénglykolu, ktorý zabezpečuje jeho stabilizáciu pri teplotách nižších ako 0 OC.0.1 to 0.6 wt. a nonionic emulsifier produced by the exyetylation of higher fatty alcohols (Slovanik M 640). 5 to 11.5 wt. ethylene glycol, which provides a stabilization at temperatures below 0 o C.
Ďalej sa do finalizujúceho přípravku přidá 0,1 až 1,0 % hmot. formaldehydu, ktorý spíňa funkciu antibakteriálneho komponenta.Furthermore, 0.1 to 1.0 wt. formaldehyde, which functions as an antibacterial component.
Ďalej sa přidá 0,1 až 5 % hmot. polysacharidu (Rodopol] a za miešania sa přidává jemne zomletá účinná látka 2-chlór-4,6-bis-etylamíno-triazínu (Simazínj v množstve 10 až 30 % hmot. Zmes sa melie mokrým mletím, na závěr sa zriedi vodou tak, aby výsledný produkt obsahoval 40 až 50 % hmot. účinných látok. Ďalej sa zhomogenizuje.0.1 to 5 wt. polysaccharide (Rodopol) and finely milled active ingredient 2-chloro-4,6-bis-ethylamino-triazine (Simazine in an amount of 10 to 30% by weight) is added with stirring. The mixture is ground by wet grinding, then diluted with water so that the resulting product contained 40 to 50% by weight of the active ingredients.
Selektívny herbicídny prípravok na báze MCPA, atrazínu a simazínu připravený uvedeným sposobom do formy stabilnej vodnej suspenzie. Mokré mletie a homogenizácia přípravku zabezpečujú vysokú jemnost účinných látok, vysokú suspenznú stálost i homogenitu přípravku. Poradie pridávania 2-chlór-4-izopropylamíno-6-etylamíno-l,3,5-triazínu a 2-chlór-4,6-bis etylamíno-triazínu je volitelné.A selective herbicidal composition based on MCPA, atrazine and simazine prepared as described above in the form of a stable aqueous suspension. Wet milling and homogenization of the formulation ensure high fineness of the active ingredients, high suspension stability and homogeneity of the formulation. The order of addition of 2-chloro-4-isopropylamino-6-ethylamino-1,3,5-triazine and 2-chloro-4,6-bis ethylamino-triazine is optional.
Zistili sme že závěrečné mletie přípravku možno vynechat, ak všetky účinné látky (atrazín, simazínj sú před finalizáciou požadovanej jemnosti, t. j. zbytok na site 125 μ je menší ako 0,1 %.We have found that the final grinding of the preparation can be omitted if all the active substances (atrazine, simazine) are before finalizing the desired fineness, i.e. the residue on the 125 μ sieve is less than 0.1%.
Je výhodné spojit proces mletia s přidáním polysacharidu a uskutočniť ho po přidaní účinnej druhej látky.It is preferred to combine the grinding process with the addition of the polysaccharide and to carry out it after the addition of the active second substance.
Tiež je výhodné přidat do roztoku soli 2-metyl-4-chlórfenoxyoctovej kyseliny druhů účinnú látku stabilizovanú tenzidom, emulgátorom, etylénglykolom, formaldehydom a polysacharidom. Postup možno modifikovat aj tak, že sa do roztoku soli MCPA přidá za miešania stabilná vodná suspenzia, obsahujúca napr. 40 % hmot. účinnej látky atrazínu a ďalej sa přidá simazín.It is also preferred to add a surfactant, emulsifier, ethylene glycol, formaldehyde and polysaccharide stabilized active ingredient to the solution of the 2-methyl-4-chlorophenoxyacetic acid salt of the species. The process may also be modified by adding to the MCPA salt solution a stable aqueous suspension containing e.g. 40 wt. of the active substance atrazine and further adding simazine.

Do 475 g roztoku obsahujúceho 29,3 % 2-metyl-4-chlórfenoxyoctovej kyseliny vo formě dimetylamínovej soli sa za miešania přidalo 142 g 2-chlór-4-izopropylamíno-6-etylamíno-l,3,5-triazínu. Ďalej sa přidalo 9 gramov neionového tenzidu, ktorý bol tvořený zmesným kopolymérom propylénoxidu a etylénoxidu, po premiešaní sa přidal nelónový emulgátor (Slovasol SF), ktorý představuje exyetylovanú zmes vyšších mastných alkoholov.To 475 g of a solution containing 29.3% 2-methyl-4-chlorophenoxyacetic acid as the dimethylamine salt was added with stirring 142 g of 2-chloro-4-isopropylamino-6-ethylamino-1,3,5-triazine. Next, 9 grams of a nonionic surfactant consisting of a mixed copolymer of propylene oxide and ethylene oxide was added, followed by the addition of a non-ionic emulsifier (Slovasol SF), which represents an exetylated mixture of higher fatty alcohols.
Ďalej ša do 210 g vody přidalo za miešania 10 g etylénglykolu a 0,15 g polysacharidu, vzniklý roztok sa přidal k finalizujúcim sa účinným látkám. Před mletím sa ešte přidalo 0,5 ml formaldehydu a 140 g 2-chlór-4,6-bis-etylamíno-triazínu. Vzniklá zmes sa premlela mokrým mletím; ďalej sa odobrala vzorka na analýzu obsahu účinných látok a doriedila sa vodou. Po zriedení sa zmes homogenizovala 30 minút. Analýzou sa zistila suspenzná stálost 1 % roztoku 90,3 % počas 30 minút.Furthermore, 10 g of ethylene glycol and 0.15 g of polysaccharide were added to 210 g of water with stirring, and the resulting solution was added to the finalizing active ingredients. 0.5 ml of formaldehyde and 140 g of 2-chloro-4,6-bis-ethylamino-triazine were added before milling. The resulting mixture was ground by wet grinding; further, a sample was taken for analysis of the active substance content and diluted with water. After dilution, the mixture was homogenized for 30 minutes. Analysis showed a suspension stability of 1% 90.3% solution for 30 minutes.
