Abstract
The invention provides a weed killer composition.The weed killer composition is characterized by comprising three active ingredients of fluroxypyr, metolachlor and hexazinone, and fluroxypyr, metolachlor and hexazinone account for 30-50%, 18-25% and 9-15% of the total weight respectively.Fluroxypyr, metolachlor and hexazinone are compounded according to a certain ratio to form the weed killer composition, the three ingredients interact after being mixed, the obtained weed killer composition is beneficial for forming weed resistance, and weed killing activity of the weed killer is greatly improved; the three raw materials are mixed and take effect in a complementary mode, and the range of the weed killing spectrum is enlarged; compared with single agents containing the active ingredients, production and use cost is reduced, and cost of using the weed killer is saved for farmers.
Description
Technical field
The present invention relates to technical field of pesticide, particularly to a kind of herbicidal composition.
Background technology
Weeds are considered as one of main formidable opponent of serious harm crops.Widely distributed miscellaneous in the whole world
Grass has kind more than 30000, the most about 1800 kinds of weeds crops to be caused harm in various degree, causes
Crop production reduction is up to 9.7%.In recent years, along with Planter industry structure adjustment and cropping system change, special
It not to use chemical herbicide, existing single dose and compound herbicide to there is poor stability continuously, or
Herbicidal effect is the highest, or use cost is higher, or the shortcoming of the aspect such as range is narrower, causes quick
Disappearance and the tolerant weeds of perception weeds are survived and constantly breed, and China's farmland weed is to herbicide
Resistance problem starts to highlight.In order to reduce agriculture production cost, promote agro based economic development, compel to be essential
Want a kind of new herbicides compositions.
Fluroxypyr, chemical entitled 4-amino-3, the chloro-6-of 5-bis-fluoro-2-pyridine fluoroacetic acid, belong to pyridine
Fluoroacetic acid class herbicide.There is Uptake and translocation effect, have typical hormone like herbicide to react.Miao Hou
Using, there is the reaction of classical hormones class herbicide in sensitive crop.Cereal crop uses optimum period
Wider, can be used for the ground such as Semen Tritici aestivi, Fructus Hordei Vulgaris, Semen Maydis, Fructus Vitis viniferae and orchard, pasture, forest farm and prevent and kill off broad-leaved
Weeds, such as weeds such as Herba Galii Teneri, Herba seu Flos Convolvuli arvensis, Herba Capsellae, Herba stellariae mediae, volume stem Herba Amaranthi tricoloris, Herba Portulacaes.
Isopropyl methoxalamine, chemical entitled 2-methyl-6-ethyl-N-(1-methyl-2-methoxyethyl)-N-chloro second
Anilid, isopropyl methoxalamine is broad spectrum activity herbicides for before-seedling stage.Isopropyl methoxalamine is mainly by planting
The hypocotyl of the plumelet of thing i.e. unifacial leaf and plumule, dicotyledon absorbs upwards conducts.After emerging
Upwards conduct mainly by root absorption, suppression plumelet and the growth of root.If soil moisture content is good, weeds quilt
Kill in the plumelet phase；If soil moisture is few, increase along with rainfall soil moisture after weeds are unearthed, miscellaneous
After grass absorbs all your leaf shrinkages, whole strain is withered.Therefore dispenser should be carried out before weeds germinate.
Hexazinone, chemical entitled 3-cyclohexyl-6-dimethylamino-1-methyl isophthalic acid, 3,5-triazine-2,4-diketone,
Being interior suction selective herbicide, plant roots, leaf can absorb, and mainly conducted by xylem, to pine
Usage tree root does not injure, and is excellent woods herbicide.
Summary of the invention
For solving the problem of above-mentioned existence, it is an object of the invention to provide a kind of herbicidal composition.
Described herbicidal composition, by fluroxypyr, isopropyl methoxalamine and hexazinone according to a certain percentage
Compounding and form, produce reciprocal action after three's mixing, the Herbicidal combinations obtained is conducive to delaying weeds
The formation of resistance, is greatly enhanced the removing activity of herbicide；Three kinds of raw material mixing, action compensating,
Expand the scope of herbicidal spectrum；And compared with each component single dose, produce and use cost reduces, save agriculture
Civilian dose of cost.
For reaching above-mentioned purpose, the technical scheme is that
A kind of herbicidal composition, described herbicidal composition contains fluroxypyr, isopropyl first grass
Amine and three kinds of active component of hexazinone, wherein, described each active component accounts for the ratio of gross weight respectively and is:
Fluroxypyr: 30-50%；Isopropyl methoxalamine；18-25%；Hexazinone: 9-15%.
Degree further, described each active component accounts for the ratio of gross weight respectively and is: fluroxypyr:
35-45%；Isopropyl methoxalamine；20-25%；Hexazinone: 12-15%.
Further, described each active component accounts for the ratio of gross weight respectively and is: fluroxypyr:
42%；Isopropyl methoxalamine；23%；Hexazinone: 13%.
Separately having, described herbicide is possibly together with dispersant, surfactant, solvent, defoamer, safety
One or more in agent.
Further, described safener is fenclorim.
Meanwhile, described surfactant is polyoxyethylenated alcohol sodium sulfate or DBSA
Any one in sodium or fatty alcohol-polyoxyethylene ether.
And, the dosage form of described herbicidal composition is suspending agent, cream, microemulsion, wettable powder
Or any one in water dispersible granules.
The beneficial effects of the present invention is:
(1) herbicidal composition that the present invention provides, by fluroxypyr, isopropyl methoxalamine and ring
Piperazine ketone certain proportion is compounding to be formed, and produces reciprocal action after three's mixing, and the complex weedicide obtained has
It is beneficial to delay the formation of Weed Resistance, is greatly enhanced the removing activity of herbicide；
(2) herbicidal composition that the present invention provides, three kinds of raw material mixing, action compensating, expansion removes
The scope of grass spectrum；
(3) herbicidal composition that the present invention provides, compared with the single dose of each component, reduces production
And use cost, save peasant and use agent cost.
