Abstract
The invention discloses a herbicide composition for preventing and removing weeds in farmlands and application thereof, in particular a herbicide composition used for preventing and treating gramineous weeds and broadleaf weeds between cornfields. The herbicide composition is a ternary herbicide mixed agent comprising the active components of nicosulfuron, atrazine and fluroxypyr. In the composition, the weight ratio of the nicosulfuron, the atrazine and the fluroxypyr is 1-50:1-80:1-50, preferably 1-10:1-50:1-20. The invention has reasonable components, has better preventing effect in comparison with the activity of each component when being applied independently, has a synergistic action, expands the preventing and treating spectra of the weeds, reduces the application frequency, lowers the preventing and treating 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 an obvious preventing and treating effect of 85.80-95.13% to the gramineous weeds and the broadleaf weeds between the cornfields.

The present invention relates to a kind of herbicidal composition, be specifically related to a kind of weed killer herbicide for control of maize field grassy weed, sedge family and broad leaved weed, it is the active ternary herbicidal composition formed by nicosulfuron, atrazine and fluroxypyr.
Background technology
The English common name nicosulfuron of nicosulfuron, the beautiful agriculture of other Chinese name is happy, cigarette sulphur is grand, molecular formula C

6s.Nicosulfuron is a kind of sulfonylurea corn field herbicide, with effectively preventing and kill off multiple annual gramineous weed, broad leaved weed and sedge weed in corn field after low dosage bud.It is absorbed rapidly by leaf and root, and is conducted rapidly by xylem and phloem.The synthesis of branched-chain amino acid is stoped by acetolactate synthestase.Use rear weeds to stop growing immediately, 4-5 days young leaves fade, downright bad, and progressively expand to whole plant, under general condition, after process, 20-25 days plant are dead.
The English common name atrazine of atrazine, other Chinese name atrazine, green bristlegrass are gone to the greatest extent, Aunar draws piperazine, garden is protected clean, molecular formula C

5.Atrazine is before selectivity inner sucting conduction type seedling, herbicide after seedling.Root absorption is main, and cauline leaf absorbs seldom, is transmitted to rapidly plant meristematic tissue and leaf portion, and interference photosynthesis, makes weeds lethal.
The English common name fluroxypyr of fluroxypyr, other Chinese name makes it grand, and fluorine grass is fixed, molecular formula C

3.Fluroxypyr belongs to inner sucting conduction type herbicide after seedling, is absorbed by plants very soon after medicine, makes sensitive plant occur the reaction of classical hormones class weed killer herbicide, plant deformity, distortion.Temperature on the final effect of its weeding without impact.
In actual use, nicosulfuron has good control efficiency to the most grass family between corn field, sedge weed, but not satisfactory to part broad leaved weed preventive effect, and corn weeds in field has the trend strengthened gradually to nicosulfuron resistance; Atrazine, as a kind of conventional corn field herbicide, has weeds and prevents and kill off preferably and sealing effect, but increases year by year due to resistance problem usage amount; Fluroxypyr has good preventive effect to broad leaved weed between corn field, but poor to grass family, sedge weed preventive effect.Therefore, nicosulfuron, atrazine and fluroxypyr are carried out rational mixture, have and expand control of weeds spectrum, minimizing spraying times, reduce the effect of cost accounting.
Summary of the invention
The object of the present invention is to provide a kind of component reasonable, drug cost is low, the herbicidal composition not easily developed immunity to drugs, all has good control efficiency to grassy weed, sedge family and broad leaved weed, has positive role to slowing down the aspect such as Weed Resistance and shift of weed community.
Another object of the present invention is to the application that herbicidal composition is provided.
In order to overcome the defect of existing unitary agent or binary preparation, the technical scheme of herbicidal composition of the present invention solves like this:
