Description
Vynález sa týká herbicídneho přípravku na bás® 4-amino-l-fenyl-5-chlór-6-pyridazónu vo formě dispergovaného koncentrátu vo vodě a spSsobu jeho výroby.The invention relates to a herbicidal composition based on 4-amino-1-phenyl-5-chloro-6-pyridazone in the form of a dispersed concentrate in water and to a process for its preparation.
4-amino-l-fenyl-5-chlór-6-pyridazón/chloridazon/ sa používá ako herbicid v polnohospodárstve na ošetrenie cukrovej a krmnej řepy. Vo forme dispergovatelného prásku sa vyrába u nás pod názvom Burex 80. Určitá nevýhoda přípravku je prašnost’ pri výrobě ako i pri přípravě aplikačného postreku. Z dovodov vyšŠej jemnosti pevných častíc s možnosťou pásovéj aplikácie pri použití ako i zníženia dávok účinnéj látky na hektár, zavádzajú da pesticidně přípravky vo forme dispergovatelného koncentrátu vodného /DKV/. Doteraz známe DKV boli prevážne toxitropnej hustej konzistencie, pričom boli tažkosti s vyprázdňovanim obalov. Na zlepšenie vyprázdňovania sa museli používat’ poměrně drahé povrchovoaktívne látky.4-Amino-1-phenyl-5-chloro-6-pyridazone (chloridazon) is used as a herbicide in agriculture for the treatment of sugar beet and fodder beet. In the form of a dispersible powder, it is produced in our country under the name Burex 80. A certain disadvantage of the preparation is dust in the production as well as in the preparation of the application spray. Due to the higher fineness of solid particles with the possibility of band application in use as well as to reduce the rates of active substance per hectare, the pesticidal formulations introduce in the form of a dispersible aqueous concentrate (DKV). Hitherto known DKVs were predominantly of toxitropic thick consistency, with difficulties in emptying the packages. Relatively expensive surfactants had to be used to improve emptying.

Po homogenizácii se přidá účinná látka 4-ami-l-fenyl-5-chlór-6-pyridazón, cíalej polysacharid na báze mikroorganizmov radu Xantomonázy ( Rhodopol 23 ) vo vodě a etylénglykol. Získaná suspenzia sa za mokra premelie a po homogenizácii sa herbicídny prípravok doriedi s vodou na požadovánu koncentráciu 4-amino-l-fenyl-5-chlór-6-pyridazónu. Rhodopol 23 sa m6že přidat vo forme prášku, gelu vo vodě, alebo vo vodnom roztoku etylénglykolu. Rhodopol 23 sa přidá k zmesi před alebo po mletí suspenzie za mokra a po homogenizácii sa herbicídny prípravok doriedi s vodou.A process for the preparation of a herbicidal preparation consisting in the preparation of an aqueous formaldehyde solution to which a polydimethylsiloxane (Lukosan S) is added and a sulphite extract, a polyadduct of ethylene oxide and castor oil (Slovazol EL) are added to the emulsion obtained. After homogenization, the active ingredient 4-amino-1-phenyl-5-chloro-6-pyridazone, followed by a polysaccharide based on microorganisms of the Xantomonase series (Rhodopol 23) in water and ethylene glycol, are added. The suspension obtained is wet-milled and, after homogenization, the herbicidal preparation is diluted with water to the desired concentration of 4-amino-1-phenyl-5-chloro-6-pyridazone. Rhodopol 23 can be added in the form of a powder, a gel in water, or in an aqueous solution of ethylene glycol. Rhodopol 23 is added to the mixture before or after wet milling of the suspension and after homogenization the herbicidal composition is diluted with water.
Výhodou podlá vynálezu je vačšia jemnosť častíc 4-amino-l-fenyl~5-chlór-6-pyridazónu ako vo forme dispergovatelného prášku. Příprava postreku v teréne je bezpečnejšia z hlediska ochrany obsluhujúceho personálu ako i vzhladom sa susediace porasty a okolitú přírodu. Odstráni sa možnost zanášania práškovitého přípravku vetrom. Výroba herbicídneho přípravku vo forme DKV je ovela bezpečnejŠia, pretože sa odstranila moŽnosť výbuchu organických prachov. Odstránila sa nutnost mletia, homogenizácie, připadne balenia dispergovatelných práškov v inertnej atmosféře. / , , > a An advantage of the invention is the greater fineness of the particles of 4-amino-1-phenyl-5-chloro-6-pyridazone than in the form of a dispersible powder. Preparation of spraying in the field is safer in terms of protection of operating personnel as well as with respect to the adjacent vegetation and the surrounding nature. The possibility of clogging of the powdered preparation by wind is eliminated. The production of a herbicidal preparation in the form of DKV is much safer because the possibility of an explosion of organic dusts has been eliminated. The need for grinding, homogenization or packaging of dispersible powders in an inert atmosphere has been eliminated. /,,> a
Výhodné je přidávat polysacharid na báze produktu mikroorganizmov rodu Xantomonas po mokrom mletí zmesi, alebo před a po mokrom mletí zmesi. Pri mechanickom mletí za mokra sa menia vlastnosti polysacharidu na báze produktu mikroorganizmov rodu Xantomonas, čo sposobuje znižovanie stálosti suspenzie disperzného koncentrátu, resp. vodnej suspenzie herbicídneho přípravku. Pri podávaní polysacharidu na báze produktu mikroorganizmov rodu Xantomonas k zmesi před mokrým mletím musí sa zvýšit množstvo polysacharidu na báze produktu mikroorganizmov rodu Xantomonas^by sa udržala stabilita DKV resp. vodnej suspenzie herbicídneho přípravku. Polysacharid na báze produktu mikroorganizmov rodu Xantomonas je vo forme prášku, ktorý pri styku s vodou a/alebo etylénglykolom vytvárajú gely. Pri dlhotrvajúcom miešaní zmesi s práškovým polysacharidom na báze produktu mikroorganizmov rodu Xantomonas sa musí přidat’ vačšie množstvo tohto polysacharidu ako pri přidávaní polysacharidu vo forme vodného a/alebo etylénglykolového gelu k zmesi pri tej istej stabilitě disperzného herbicídneho přípravku. Vyplývá to z toho, že pri mechanickom miešaní, resp. mletí polysacharidu dochádza k deštrukcii molekuly polysacharidu.It is preferred to add the polysaccharide based on the product of microorganisms of the genus Xantomonas after wet grinding of the mixture, or before and after wet grinding of the mixture. During wet mechanical milling, the properties of the polysaccharide based on the product of microorganisms of the genus Xantomonas change, which causes a reduction in the stability of the suspension of the dispersion concentrate, resp. aqueous suspension of the herbicidal preparation. When administering a polysaccharide based on a product of microorganisms of the genus Xantomonas to the mixture before wet milling, the amount of polysaccharide based on a product of microorganisms of the genus Xantomonas must be increased. aqueous suspension of the herbicidal preparation. The polysaccharide based on the product of microorganisms of the genus Xantomonas is in the form of a powder which forms gels on contact with water and / or ethylene glycol. Longer mixing of the mixture with the powdered polysaccharide based on the product of microorganisms of the genus Xantomonas must add more polysaccharide than adding the polysaccharide in the form of an aqueous and / or ethylene glycol gel to the mixture at the same stability of the dispersed herbicidal preparation. This follows from the fact that during mechanical mixing, resp. grinding of the polysaccharide destroys the polysaccharide molecule.
