Abstract

The invention relates to a herbicide composite used in a paddy field. The active ingredient of the composite is formed by one or two of metamifop, bensulfuron-methyl, pyrazosulfuron, quinclorac, bentazone, bispyribac-sodium, 2-methyl-4-chloro-phenoxyacetic acid, penoxsulam and imidazolinone herbicides so as to form a binary herbicide composite or a ternary herbicide composite. The herbicide composite used in the paddy field can effectively remove various weeds in grass family, broad leaf weeds and cyperaceae weeds in the paddy field in a disposable way, and has special effects on cockspur grasses, moleplant seeds, crabgrass and the like which are difficult to be prevented in the directly-sown paddy fields.

Description

The herbicidal composition that is used for paddy field

Technical field

The present invention relates to a kind of herbicidal composition that is used for paddy field, said composition can disposablely effectively be prevented and kill off multiple grassy weed, broad leaved weed and sedge weed in the paddy field, and direct sowing rice field difficult anti-barnyard grass grass, moleplant seed and lady's-grass etc. are had special efficacy.

Technical background

Paddy rice is one of China staple crops, continuous expansion along with its cultivated area, the rice field crop smothering also day by day enlarges in the production that constantly enlarges, endanger also serious day by day, and can effectively control crop smothering in the paddy field, the stabilization of rice high yield becomes one of major subjects of modern agricultural herbicide research.It is narrow that there is careless extremely spectrum mostly in herbicide for paddy field at present, can not play extraordinary effect simultaneously to Tanaka's grassy weed and broad leaved weed and sedge weed, general peasant needs secondary dispenser even three dispensers just can reach desirable preventive effect, and this herbicide composition for paddy fields that we discover can disposablely effectively be prevented and kill off multiple grassy weed (barnyard grass grass, moleplant seed and lady's-grass etc. are had special efficacy) and broad leaved weed and nutgrass flatsedge.This herbicidal composition is efficient, to rice safety and moderate cost.

20th century the mid-1970s, it is found that fragrant phenoxy base propionic acid ester weed killer herbicide has fabulous selectivity in crops such as paddy rice, can be widely used in postemergence weed control.Oxazole acyl grass amine (English general Metamifop by name, chemical name: (R)-2-{4-[(6-chloro-2-benzo) oxygen] phenoxy group }-N-(2-fluorophenyl-N-methyl propanamide) belongs to such weed killer herbicide, can be fabulous prevent and kill off most of annual gramineous weeds, and different with this type of weed killer herbicide be that it is safe to paddy rice, this is one of its key property.

We find that after deliberation one or both weed killer herbicides in oxazole acyl grass amine and bensulfuron-methyl, pyrazosulfuron, dichloro quinolinic acid, Bentazon, two careless ether, methoxone, penoxsuam and the azoles humulone carry out the composite very obvious synergistic effect that has, preventive effect to paddy field weed increases significantly, and can enlarge grass spectrum extremely.

Summary of the invention

The object of the present invention is to provide a kind of herbicide composition for paddy fields that is used for of Han You oxazole acyl grass amine.This herbicidal composition can be prevented and kill off grassy weed, can prevent and kill off broad leaved weed and sedge weed again, and preventive effect is good.

The invention provides a kind of herbicidal composition that is used for paddy field, any one or two kind of the active component of this herbicidal composition in oxazole acyl grass amine and bensulfuron-methyl, pyrazosulfuron, dichloro quinolinic acid, Bentazon, two careless ether, methoxone, penoxsuam and azoles humulone weed killer herbicide are formed.Described active component is added various assistant agents and is formed binary herbicidal composition or ternary herbicidal composition afterwards with the deionized water deficiency.In described binary herbicidal composition, the weight ratio of two kinds of active components is 1: 15 to 15: 1, and preferred weight ratio is 1: 9 to 9: 1, more preferably 1: 5 to 5: 1.In the ternary herbicidal composition, the weight ratio of three kinds of components is 1-10: 1-30: 0.1-5, and preferred weight ratio is 8.5: 2: 0.5 or 4: 17.6: 0.4.

Active component in the herbicidal composition of the present invention is 1~60% of a herbicidal composition gross weight, and all the other are that agricultural goes up acceptable surfactant, solid packing or liquid diluent, antifreezing agent, defoamer, deionized water and their combination.

Comprise at least a surfactant and at least a solid carrier or liquid diluent in the herbicidal composition of the present invention.Described surfactant is alkylsulfonate, Negel, alkylphenol polyoxyethylene, lauryl sodium sulfate, calcium dodecyl benzene sulfonate, lignosulfonates, carboxymethyl cellulose, fat alcohol ethoxyl compound, triphenyl vinyl phenol, ethoxy compound, castor oil ethoxy compound, polyoxyethylene/polyoxypropylene compound, amine ethoxy compound etc.; Described solid packing is bentonite, white carbon, kaolin, potter's clay, diatomite, starch, precipitated calcium carbonate etc.; Described liquid diluent is cyclohexanone, dimethylacetylamide, methyl oleate, dimethyl sulfoxide (DMSO), S-100 (available from Hualun Chemical Co., Ltd., Jiangsu), S-150 (available from Hualun Chemical Co., Ltd., Jiangsu), S-200 (available from Hualun Chemical Co., Ltd., Jiangsu), dimethylbenzene, trimethylbenzene, methyl naphthalene, corn oil, soybean oil, rapeseed oil, peanut oil, water etc.In embodiments of the present invention, described antifreezing agent is a propane diols, ethylene glycol, glycerine etc.; Described defoamer is silicone based defoamer.

Herbicidal composition of the present invention can be made agricultural and go up any formulation of acceptable, includes but not limited to: oil suspending agent, missible oil, wetting powder, water dispersible granules, aqueous emulsion, suspending agent, microemulsion and micro-capsule suspension etc.

The effectiveness of the herbicidal composition that oxazole acyl grass amine and specific compound are formed with certain proportion among the Ben Faming and the simple superposition that activity level has exceeded each component have synergistic effect; Simultaneously, present composition preparation has efficient herbicidal effect, kills careless spectrum width, moderate to rice safety, cost, grassy weed and broad leaved weed and sedge weed are had better preventive effect characteristics, and a dispenser is the harm of weeds of whole season of controlled paddy field.
