Problems solved by technology

Make it cumbersome because of the extra cost or labor involved
[0004] Additionally, particles granulated immediately after granulation have a tendency to agglomerate, which occurs prior to the drying process, resulting in reduced formulation yields

Embodiment

[0021] The present invention is now explained by the production examples and test examples detailed below, but the present invention is not limited to these examples.

[0022] In the following examples, parts refer to parts by weight unless otherwise specified.

preparation Embodiment 1

[0024] In 51 parts adopting the air grinder to grind into fluoxazinone with an average particle diameter of 4 μm, add 4 parts of sodium salt of a copolymer of maleic acid and diisobutylene (trade name: DEMOL EP powder, produced by Kao Company), 6 parts Parts of sodium salt of arylsulfonic acid formaldehyde aqueous condensate (trade name: DEMOLSNB, produced by Kao Company), 2 parts of sodium lauryl sulfate (trade name: EMAL10 powder, produced by Kao Company) and 37 parts of kaolin (commodity Name: Shokozan A clay, produced by Shokozan Kogyosho), mixed with a juice mixer for 5 minutes. Thereafter, the resulting mixture was kneaded with 16 parts of water for 5 min in a mortar. The kneaded mixture was granulated using an extruder (Hatashiki granulator manufactured by Hata Seisakusho) with a 0.7 mm φ filter net, treated with a spheroidizer, dried at 60° C. for 12 min, and sieved to obtain a particle size of 500 Water-dispersible particles of the invention of ~1180 μm.

preparation Embodiment 2

[0026] In 51 parts of fluoxazinones that are ground into an average particle diameter of 4 μm using an air mill, add 1.5 parts of sodium salt of a copolymer of maleic acid and diisobutylene (trade name: DEMOL EP powder, produced by Kao Company), 3.5 parts Parts of sodium salt of arylsulfonic acid formaldehyde aqueous condensate (trade name: DEMOL SNB, produced by Kao company), 2 parts of sodium lauryl sulfate (trade name: EMAL10 powder, produced by Kao company) and 42 parts of kaolin ( Trade name: Shokozan Aclay, produced by Shokozan Kogyosho), mixed for 10 min using a small nautamixer (Labomixer LV-0, produced by Hosokawamicron). Thereafter, the resulting mixture was kneaded with 16 parts of water for 5 min in a kneader (KDHJ-10 type, manufactured by Fujipaudal). Gained kneading mixture adopts extruder (TWIN-DOME GRAN, produced by Fujipaudal) with 0.7mm phi filter net to carry out granulation, at 60 ℃, dry 12min, adopt spheroidizing machine to process, make particle size 500 ...

Abstract

Water dispersible granules comprising (a) N-(7-fluoro-3,4-dihydro-3-oxo-4-prop-2-ynyl-2H-1,4-benzoxazin-6-yl)cyclohex-1-ene-1,2-dicarboximide, (b-1) an arylsulfonic acid formalin condensate or its salt, (b-2) a polycarboxylate surfactant and (c) a mineral carrier have a good disintegrability in water and can be produced in good yield.

Description

field of invention [0001] The present invention relates to N-(7-fluoro-3,4-dihydro-3-oxo-4-prop-2-ynyl-2H-1,4-benzoxazin-6-yl)cyclohexyl-1 Water-dispersible granules of -ene-1,2-dicarboximide (fluoxazinone). Background technique [0002] Fluoxazinone is a herbicidal compound described in USP4640707. The present invention provides novel water-dispersible granules having fluoxazinone as an active ingredient. [0003] Water-dispersible granules are usually applied to soil after being diluted 20-10000 times with water. It is an easy-to-handle formulation as the user can measure by volume without pulverization. However, when the disintegration ability of water-dispersible granules in water is not good, it will lead to unevenness of the active ingredient in the diluent, resulting in uniform application. This non-uniform application results in reduced efficacy where the dosage is small and causes phytotoxicity problems where agglomerated particles that do n...
