The invention relates to a herbicide composition for preventing and removing weeds in farmlands and an application, in particular to a herbicide used for preventing and removing gramineous weeds, broadleaf weeds and sedge weeds in paddy fields. The herbicide composition is a binary herbicide mixed agent taking penoxsulam and bensulfuron methyl as active components. The weight ratio of the penoxsulam to the bensulfuron methyl in the composition is 1.6:1-1:40, preferably 1.6:1-1:10. The compound herbicide can be prepared into water dispersed granules, a suspending agent, an oil suspending agentand wettable powder. The invention is used for preventing and removing the weeds in the paddy fields, has reasonable components and better preventing effect in comparison with the activity of the components when being applied independently, expands the preventing and removing spectra of the weeds, lowers the preventing and removing cost, delays the generation of the resistibility of the weeds, has good safety to crops and conforms to the safety requirement of pesticide preparations. The invention has the fresh-weight average preventing and treating effect of 87.35-98.01% to the gramineous weeds, the broadleaf weeds and the sedge weeds in the paddy fields after being applied for thirty days.

The pesticide composition has a remarkable synergistic effect in the matching range, the use amount of pesticide is reduced, the number of use times of the pesticide is reduced, the pesticide cost is reduced, and an adverse effect of the pesticide on ecological environment is reduced; the weeding spectrum is enlarged, the problem about various weeds is solved through one-time pesticide application, and the defect and the limitation during single-agent use are made up; the service life of the pesticide composition is prolonged; the pesticide composition has important significance on comprehensive treatment of weed resistance; and the pesticide composition rapidly exerts the pesticide effect, the lasting period is long, the use cost is low, and the pesticide composition can be used for controlling rice grassy weeds, broad leaved weeds and sedge family weeds.

The invention belongs to the technology field of pesticide and discloses a mixed herbicide containing fenoxaprop-p-ethyl, clodinafop-propargyl and fluroxypyr. The herbicide takes fenoxaprop-p-ethyl, clodinafop-propargyl and fluroxypyr as main effective ingredients, wherein the mass ratio of fenoxaprop-p-ethyl to clodinafop-propargyl to fluroxypyr is (80-98):(0.1-10):(0.1-10). The invention also discloses application of the mixed herbicide to weeding in a paddy field. The mixed herbicide has broad weeding spectrum through mixture of weed killers, so as to improve the weeding effect; the mixed herbicide has the advantages of having quick effect, long lasting period, thorough weeding effect, low residue, low toxicity, safety, environment protection and the like and having capability of delaying pesticide resistance of the herbicide, and has prominent prevention and control effects on grassy weeds, broad leaf weeds, sedge weeds in the paddy field such as Alternanthera philoxeroides, amur foxtail and difformed galingale herbs.

The invention discloses a mixed herbicide containing glyphosate and bispyribac-sodium, belonging to the technology field of pesticides. The herbicide takes glyphosate and bispyribac-sodium as main effective ingredients, wherein the mass ratio of glyphosate to bispyribac-sodium is (80-98):(0.1-10). The invention also discloses application of the mixed herbicide to post-emergence weeding in a paddy field. The mixed herbicide has wide weeding spectrum through mixture of weed killers, so as to improve the weeding effect; the mixed herbicide has the advantages of having quick effect, long lasting period, thorough weeding effect, low residue, low toxicity, safety, environment protection and the like and having capability of delaying pesticide resistance of the herbicide, and has prominent prevention and control effect on grassy weeds, broad leaf weeds, sedge weeds in the paddy field such as barnyard grass, leptochloa chinensis, difformed galingale herb, Eleocharis yokoscensis, Sagittaria pygmaea, Rotala indica and Marsilea quadrifolia, and therefore, the mixed herbicide is high-quality post-emergence chemical herbicide.

The invention belongs to the technical field of pesticides, and discloses a wheat field and corn field weeding composition and a medicinal preparation thereof. The weeding composition comprises, by weight, 5-40 parts of oxadiazon, 2-30 parts of diflufenican and 2-20 parts of flufenacet. Different auxiliary materials are added to prepare missible oil, a suspoemulsion, a suspension, a wettable pulvis or a water dispersible granule. The weeding composition utilizes the different action mechanisms of the oxadiazon, diflufenican and flufenacet, and the above three herbicides are compounded to achieve synergistic effects. The above ternary herbicide composition can effectively control diseases of annual gramineous weeds and sedge weeds in the corn field and the wheat field, and especially has agood control effect on malignant weeds in the wheat field, such as bromegrass, Aegilops tauschii, wild oats and Lolium multiflorum; and test proves that the composition is safe to wheat, corn and next-stubble crops, and is an ideal wheat field and corn field herbicide composition.

A paddy field herbicide compounded with benzobicylon comprises the following materials by weight: 5 to 80 percent of effective components, 5 to 20 percent of additives and 5 to 80 percent of filling materials, wherein the first effective component is benzobicylon; the second effective component is any one of acetochlor, metolachlor, propisochlor, pretilachlor, butachlor, mefenacet, penoxsulam, fenpyroxim, quinclorac, bensulfuron, pyrazosulfuron, cinosulfuron, clomazone, fenoxaprop-P-ethyl, carfentrazone and isoproturon, wherein the weight ratio between the first effective component and the second effective component is (1:8) to (8:1). The paddy field herbicide has the technical effects that the use is economical and efficient; the safety is high; the control effect of weeds of the grass family, the broad-leafed family and the sedge family in the paddy field is improved; particularly, the control effect of weeds of the broad-leafed family is remarkably improved; the herbicide controlling spectrum is broadened; the safety degree for paddy rice is improved; the dosage as well as the control cost is reduced.
