Abstract
A herbicide compsns. in the form of wettable powder, particle, tablet, suspension, or suspended emulsion contains cyclosulfamuron, cinmethylin, cyclopentaoxadiazon, surfactant and carrier.
Description
The present invention relates to a kind of herbicidal composition that contains effective composition AC322140, cinmethylin, pentoxazone, particularly relate to the herbicidal composition that is used for agent for removing grass in paddy field.
At present, the product that herbicide for paddy field is commonly used has: the composition of acetamide-group herbicides and sulfonylurea herbicide is as Acetochlor+Bensulfuron-methyl; Acetochlor+Bensulfuron-methyl+metsulfuron-methyl; Butachlor+Bensulfuron-methyl; Butachlor+Bensulfuron-methyl+metsulfuron-methyl; Isopropyl methoxalamine+Bensulfuron-methyl+metsulfuron-methyl etc.
Chinese patent CN1074086 " Herbicidal combinations " discloses two kinds of Herbicidal combinations that are used for transplanted rice field, and first kind is Bensulfuron-methyl+Acetochlor; Second kind is Bensulfuron-methyl+metsulfuron-methyl+Acetochlor.Be processed into general formulation fine granule, granule and wetting powder, as transplanting rice field " disposable herbicide ".
Chinese patent CN1077587 " fear of super-high-efficient weed killer herbicide one straw " discloses the composite high-efficiency broad spectrum herbicide for paddy field technology that is processed into of Bensulfuron-methyl+Acetochlor.
Chinese patent CN1092938 " efficient Herbicidal composition for rice field " discloses that amide substance such as Acetochlor, isopropyl methoxalamine, butachlor and sulfonylurea herbicide such as metsulfuron-methyl, Bensulfuron-methyl, careless jinx combine efficiently, the method for the herbicide for paddy field of wide spectrum.
Chinese patent CN1123085 " weed killer herbicide with broad-spectrum weed-killing activity " discloses by 3 kinds of active chemical componentses such as auxiliary agent and isopropyl methoxalamine, Bensulfuron-methyl, metsulfuron-methyl and has formed, and has the weed killer herbicide of broad-spectrum weed-killing activity.
It is poor to rice safety that these herbicidal compositions commonly used exist; The composition that contains metsulfuron-methyl easily causes poisoning to back stubble sensitive plant such as corn, soybean etc.; The long-term the said goods that uses, the part weeds develop immunity to drugs, and weed control also changes, so herbicidal effect is owed desirable deficiency.
It is good to the purpose of this invention is to provide a kind of preventive effect, to rice safety, does not influence the herbicide composition for paddy fields of succession crop.
Have now found that, cinmethylin, pentoxazone to kill careless mechanism different with acetamide-group herbicides, cinmethylin is the meristematic tissue growth inhibitor, and pentoxazone is the inhibitor of proporphyrinogen oxidase activity, and acetamide-group herbicides are protein synthesis inhibitors.Though it is identical that AC322140 and Bensulfuron-methyl kill careless mechanism, its biologically active is far above Bensulfuron-methyl.The result of the test surface, AC322140, cinmethylin, pentoxazone do not influence the normal growth of succession crop to rice safety.Therefore select different careless mechanism, the highly active new weed killer herbicides of killing for use, can make and to be confused the herbicidal composition of mending the existing product deficiency with traditional weed killer herbicide.
According to the present invention, it is AC322140 that said herbicidal composition contains effective composition, cinmethylin, pentoxazone.First kind of composition is AC322140+cinmethylin, and its weight ratio is an AC322140: cinmethylin=1: 0.4～10; Second kind of composition is AC322140+pentoxazone composition, and its weight ratio is an AC322140: pentoxazone=1: 3～45.Two kinds of compositions are equipped with suitable surfactant, carrier etc. and can be made into wetting powder, granule, tablet, suspending agent, suspended emulsion.
Herbicidal composition preparation of the present invention is than being easier to, and with first kind of composition or second kind of composition, amount is equipped with appropriate solvent, cosolvent, surfactant, carrier in accordance with regulations, and according to the production technology of different dosage form, processing is handled, and can make.
The herbicidal composition that the present invention proposes is a kind of new herbicide for paddy field, compares with herbicide for paddy field commonly used, and it is better to have a herbicidal effect, to advantages such as paddy rice and succession crop safety.It is a kind of comparatively ideal herbicide composition for paddy fields.
The following stated embodiment describes the present invention in detail.In an embodiment, and outer, each percentage of all umbers all by weight unless otherwise indicated.
