Abstract
The invention discloses a weedicide combination, including the active components in weight percent: 2-(1, 3-benzothiazol-2-oxy) - N - (4 - fluorophenyl ) - N - (1 -methylethyle) acetamide 50-100% and sulfonylurea weedicide 0-50%. The sulfonylurea weedicide selects from: bensulfuron, imazosulfuron, ethoxysulfuron, cyclosulfamuron, azimsulfuron, ethersulfuron, imazosulfuron or chlorazolsulfuron. It can be processed into wettable powder, water dispersible granule, tablet, granule, and suspending agent, able to effectively prevent and eliminate various gramineous weeds, cyperus weeds and broad-leaved weeds in the rice field.
Description
Technical field
The invention belongs to the pesticide herbicide field, specifically, it relates to preparation and the application that the Herbicidal combinations of paddy field grassy weed and broad leaved weed is prevented and kill off in a kind of new being used to.
Background technology
2-(1,3-benzothiazole-2 oxygen base)-N-(4-fluorophenyl)-N-(1-Methylethyl) acetamide is a kind of novel oxyacetamide weed killer herbicide, and structural formula is as follows:
Its preparation and application are open in Chinese invention patent application CN1411719A.This compound has higher activity of weeding to grassy weed, and it is fast to have a speed of action, and the soil treatment activity of weeding is handled activity of weeding apparently higher than cauline leaf, to characteristics such as crop safeties; But it is relatively poor to the broad leaved weed preventive effect.In addition, both at home and abroad also not about 2-(1,3-benzothiazole-2 oxygen base)-N-(4-fluorophenyl)-N-(1-Methylethyl) acetamide preparation and contain the bibliographical information of the mixture of this weed killer herbicide.
Summary of the invention
In order to satisfy needs on the agricultural, to continually develop the weed killer herbicide that makes new advances, inventors of the present invention disclose the Herbicidal combinations of a kind of 2-of containing (1,3-benzothiazole-2 oxygen base)-N-(4-fluorophenyl)-N-(1-Methylethyl) acetamide.
The composition of active component and content are respectively in this Herbicidal combinations:
2-(1,3-benzothiazole-2 oxygen base)-N-(4-fluorophenyl)-N-(1-Methylethyl) acetamide: 50-100%

Halosulfuronmethyl (3-chloro-5-[4,6-dimethoxypyridin-2-base amino carbonyl amino sulfonyl]-1-methylpyrazole-4-carboxylate methyl ester, halosulfuron-methyl).
More preferably sulfonylurea herbicide is selected from: bensulfuron-methyl, pyrazosulfuron, ethoxysulfuron, AC322140 or cinosulfuron.
In the Herbicidal combinations of the present invention, more preferably the content of active component is:
2-(1,3-benzothiazole-2 oxygen base)-N-(4-fluorophenyl)-N-(1-Methylethyl) acetamide: 85-95%;
Sulfonylurea herbicide: 5-15%.
The weight percentage of active component is 1-90% in the Herbicidal combinations of the present invention, and all the other are that agricultural goes up acceptable surfactant and solid carrier or liquid diluent.
Amount of application when the content of active component depends on independent use in the present composition also depends on the mixed ratio and the synergistic effect degree of a kind of compound and another kind of compound.Usually the weight percentage of active component is the 1-90% of gross weight in the composition, and preferable is 5% to 85%.According to different preparation types, the active component content scope is different.Usually, liquid preparation contains 1-70% active substance by weight, preferably is 5-40%; Solid pharmaceutical preparation contains 5% to 85% active substance by weight, preferably is 10-40%; Suspension preparation contains the active substance of 10-60% by weight, preferably is 5-35%.
Herbicidal combinations of the present invention contains a kind of solid carrier or liquid diluent at least, and at least a surfactant, the dispersion of active component when being beneficial to use, and help making it can correctly be applied to plant.
Used solid carrier is selected from least a following material in the Herbicidal combinations of the present invention: diatomite, white carbon, bentonite, hexamethylene diamine, precipitated calcium carbonate, sodium sulphate, corn starch, gypsum, sodium bicarbonate, carboxymethyl cellulose, citric acid, talcum powder, kaolin etc.; Used liquid diluent is selected from least a following material: water, methyl alcohol, ethanol, toluene, dimethylbenzene, N, N dimethyl formamide, acetonitrile, ethylene glycol, glycerine, ethyl acetate equal solvent; Used surfactant is selected from least a following material: farming breast 2201; the newborn OP-10 of farming; the newborn T-20 of farming; the newborn 201B of farming; the newborn 0203B of farming; the newborn NP10 of farming; farming breast 1601; sodium lignin sulfonate (calcium); the phenethyl phenol polyethenoxy ether; methyl naphthalene sulfonate formaldehyde condensate; naphthalenesulfonic acid-formaldehyde condensate; aluminium-magnesium silicate; polyvinyl alcohol; xanthans; polyvinylpyrrolidone; polyvinyl acetate; lauryl sodium sulfate; neopelex; alkylaryl formaldehyde resin APEO; to tertbutyl ether; epoxidized polyether; the methanonaphthalene sodium sulfonate; N-methyl-oleoyl-sodium taurocholate; naphthalenesulfonic acid-formaldehyde condensate; cresol sulfonic acid formaldehyde condensation products sodium salt; condensation compound of methyl naphthalene sulfonic acid and formaldehyde etc.
Herbicidal combinations of the present invention can be processed into acceptable forms on any agricultural on demand.For example can be missible oil, wetting powder, water dispersible granules, suspending agent, tablet or pulvis.Wherein preferred dosage form is wetting powder, water dispersible granules or suspending agent.
Above preparing preparation is known in those skilled in the art, and the addition sequence of each component in the Herbicidal combinations is not had specific (special) requirements.
The present invention also comprises a kind of control method for weed: the Herbicidal combinations of the present invention of using herbicidally effective amount on the somatomedins of weeds or these weeds or place.
For some application, Herbicidal combinations of the present invention also can with other known active component for example: insecticide, bactericide, weed killer herbicide, plant growth regulator and fertilizer and/or soil structure conditioner mix and use, and can produce additional advantage and effect thus.When using the mixture of weed killer herbicide, employed relative quantity will depend on pending crop and the selectivity degree in the weed control of expection.
The 2-(1 that contains involved in the present invention, 3-benzothiazole-2 oxygen base)-the various preparations of the Herbicidal combinations of N-(4-fluorophenyl)-N-(1-Methylethyl) acetamide list active component, can be used for preventing and kill off the grassy weed in various crop field, the special paddy field, remarkably productive.
The mixture Herbicidal combinations that the present invention proposes can be used in the disposable grassy weed of preventing and kill off, as barnyard grass grass, needle spikesedge herb, moleplant seed etc. and broad leaved weed pondweed, short arrowhead, rhizoma alismatis etc. and sedge weed Herba Cyperi Glomerati etc., and, be the desirable weed killer herbicide of preventing and kill off various weeds in various crop field, the special paddy field to crop safety.This Herbicidal combinations belongs to disposable herbicide, has enlarged weed killer herbicide and has killed the grass spectrum, has improved the herbicidal effect of medicament, has reduced labour intensity.Owing to the mechanism of action difference of each single agent, there is not the problem of cross resistance simultaneously,, helps to prolong the service time of medicament so the application of composition can delay generation and the development of drug resistance or pesticide resistance weeds.
