Embodiment 1

[0023] 4% Hexazinone · Arazin Granules

[0024] Product formula: hexazinone: 1%, ametrazine: 3%, white carbon black: 2%, calcium carbonate: 1%, urea: 5%, pull open powder: 1%, xanthan gum: 1%, paste Essence: 1%, bentonite: 20%, and kaolin make up 100%.

[0025] After mixing the above formulations except xanthan gum and dextrin, pulverize them with a jet mill, then add them into a rotary granulator, add xanthan gum and dextrin, make them adsorb and granulate, and then obtain granules.

Embodiment 2

[0027] 85% hexazinone · ametrazine wettable powder

[0028] Product formula: hexazinone: 5%, ametryn: 80%, sodium lauryl sulfate: 3%, lignosulfonate: 3%, white carbon black to make up to 100%.

[0029] Add each material into a stirring tank, mix them fully under stirring conditions, and pulverize them to obtain 85% hexazinone · ametrazine wettable powder.

Embodiment 3

[0031] 40% Hexazinone·Atrime Water Suspension Concentrate

[0032] Product formula: hexazinone: 10%, ametrazine: 30%, silica: 4%, propylene glycol: 2%, EO-PO block surfactant: 5%, Nongru 600#: 10%, Make up to 100% with deionized water.

[0033] After the above components are mixed, wet pulverization is used to make the average particle size below 5 μm to obtain an aqueous suspension.

Abstract

The invention discloses a weeding combination containing hexazinone. The active ingredients of the combination adopt the mixture of hexazinone and an arbitrary component selected from ametrex, atrazine, simazine or cyanazine; the weight percentage of hexazinone is 1 to 70 percent, and the weight percentage of ametrex, atrazine, simazine or cyanazine is 3 to 80 percent; and the weight ratio of hexazinone to ametrex, atrazine, simazine or cyanazine is 1:20 to 20:1. The weeding combination is used for preventing and controlling weeds of orchards, forests, sugarcane fields or waste lands, compared with the single formulation, the preventing and controlling effect of the weeding combination is obviously improved, the application amount of pesticide can be reduced, so that the pesticide application cost is reduced, and the adverse effect on the environment by pesticide is reduced; and the service life of each single formulation can be prolonged, the use spectrum is enlarged, and the weeding combination has great significance to the overall management of vital hardiness problem of pesticide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a herbicidal composition containing hexazinone. Background technique [0002] In recent years, malignant weeds have occurred seriously, such as ferns and reeds, which have become dominant weeds in some areas, showing very strong drug resistance. The use of general herbicides or a single agent can no longer be effectively controlled. Therefore, choosing a compound mixture of pesticides has become an effective way of choice at present. By adjusting the ratio of different pesticides, the pesticides with complementary properties can obtain the best synergistic effect. [0003] Hexazinone, English common name: hexazinone, 3-cyclohexyl-6-dimethylamino-1-methyl-1,3,5-triazine-2,4-dione; 3-cyclohexyl-6-( Dimethylamino)-1-methyl-1,3,5-triazine-2,4-(1H,3H)-dione; Structural formula: [0004] [0005] Hexazinone is a systemic selective herbicide, which is mainly conducted through x...
