Embodiment 1

[0019] Embodiment 1 is a dosage form preparation example, and embodiment 2 is a biological embodiment,

[0020] Example 1:

[0021] a: wettable powder

[0022] With 15 parts of weight of effective composition and 2 parts of weight of sodium dodecylbenzenesulfonate as wetting agent, 15 parts of weight of granular white carbon black as adsorbent, 10 parts of weight of sodium dodecylbenzene sulfonate as dispersant Sodium lignosulfonate and 58 parts by weight of kaolin are ultrafinely pulverized in a jet mill.

[0023] b: Powder:

[0024] 5 parts by weight of the active composition are mixed with 95 parts by weight of talcum powder as an inert substance, and uniformly pulverized in a high-speed pulverizer.

[0025] c: Water-dispersible granules:

[0026] 60 parts by weight of the active ingredient composition, 10 parts by weight of calcium lignosulfonate, 5 parts by weight of anhydrous ammonium sulfate and 25 parts by weight of kaolin are jet-milled, added with appropriate amo...

Embodiment 2

[0027] Embodiment 2, the control effect of hexazinone and diuron mixed to the weeds in sugarcane field

[0028] Location: Guangxi

[0029] Application period: 2-3 leaf stage of weeds Survey: 15 days after application Time: 2008

[0030]

[0031] Conclusion: The actual control effect of the mixture of hexazinone and diuron is higher than the expected theoretical control effect of the mixture, and it can expand the herbicidal spectrum.

Abstract

The invention belongs to a modified weeding composition as well as a preparation method and an application thereof. The modified weeding composition is a mixture of a compound (A) and diuron, effectively removes annual gramineous weeds and broadleaf weeds in cane fields, has higher prevention effect than singly using the single compound (A) or compound (B) and greatly reduces the consumption of various active substances.

Description

Technical field: [0001] The present invention relates to herbicidal compositions having improved properties. Background technique: [0002] The chemical name of the compound hexazinone is 3-cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazol-2-4-(1H,3H)dione, which is An excellent forest herbicide. Hexazinone can be used for young forest tending of evergreen coniferous forest, weeding and irrigation before afforestation, maintenance of forest fire line and forest reconstruction, etc. It can effectively control foxtail, mosquito grass, horse celery, sheep gourd, reed, camphor, artemisia narrow-leaf, fern, clematis, verticillium, spinach, wild oats, Polygonum, barnyardgrass, quinoa, etc. The woody plants that can be controlled include honeysuckle, pearl plum, hazel, spirea, acanthopanax, spring elm, aspen, birch, linden, ash, and walnut catalpa. Therefore, hexazinone is widely used in forest weeding, young forest tending, and weeding in airports, railways, industrial areas ...
