Abstract
The invention belongs to the technical field of pesticides, particularly the field of herbicides, and discloses a mixed weeding composition containing bispyribac-sodium and fluroxypyr, wherein the weeding composition takes bispyribac-sodium and fluroxypyr as main active ingredients, and the mass ratio of the bispyribac-sodium to the fluroxypyr is 0.1-99: 0.1-99. The weeding composition can be added with different surfactants, thickening agents, solvents or solid fillers and the like and processed into various formulations such as missible oil, suspending agents, water dispersible granules, wettable powder and the like. Compared with a single agent, the weeding composition delays the resistance of weeds on the premise of improving the pesticide effect, has a wide weeding spectrum and a long persistent period, can prevent and remove gramineous weeds and broadleaf weeds in paddy fields, is safe for paddy and next-stubble crops, and is an ideal paddy field herbicide.
Description
Technical field
The invention belongs to technical field of pesticide, especially the weed killer herbicide field relates to a kind of mixed herbicidal composite and application thereof that contains two careless ethers and fluroxypyr.This Herbicidal combinations is used the paddy field postemergence weed control and is had remarkable result.
Background technology
Two careless ethers have another name called Nong Meili, the salicylic acid Sulfadiazine Compound, and chemical name: 2, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of 6-.Belong to phenoxy carboxylic acid herbicides, mainly hindered aminoacid biosynthesis side chain is selective herbicide through the acid of root leaf absorption inhibition vinegar milk is synthetic, uses rice direct-seeding Tanaka, and herbicidal spectrum is wide.Its structural formula is following:
Fluroxypyr has another name called and makes it grand.Chemical name: 4-amino-3.5-two chloro-6-fluoro-pyridine-2-fluoroacetic acid, structural formula is:
This weed killer herbicide is the inner sucting conduction type herbicide after seedling.Very soon by plant absorbing, make sensitive plant the reaction of typical hormone herbicide occur behind the medicine, plant deformity, distortion.In drug resistance plant such as wheat body, can be combined into conjugates and lose toxicity, thereby have selectivity.Temperature does not have influence to the final effect of its weeding, but influences the speed of its drug effect performance.Generally the drug effect performance is slower when temperature is low, stop growing after can making dunsiekte, but dead immediately; Plant was very fast dead after temperature raise.Leaching is not remarkable in soil, and major part is distributed in the 0-10 centimetre of topsoil, under the condition of aerobic, is degraded into non-poisonous material very soon in the effect of edaphon, in soil the half life period shorter, can not exert an influence to a following batch broad leaf crop.
At present; Herbicide for paddy field is limit by crop safety; It is also limited to kill the grass spectrum, use the agent of a kind of weed killer herbicide list can not control the generation of paddy field weed completely effectively separately, moreover the weed killer herbicide consumption is excessive or the inhomogeneous residual hazard that also causes easily this season crop or succession crop of dispenser.Therefore; The present invention selects complementary two careless ether of pluses and minuses and fluroxypyr to be made into the combination agent use; So both reduced the consumption of medicament, obviously improved herbicidal effect, and also avoided this season is done the deposits yields poisoning and succession crop produced the possibility of residual hazard.
Summary of the invention
The present invention is according to the present situation of present paddy field herbicide after seedling; And behind the paddy field seedling weeds a situation arises; Provide a kind of by two careless ethers and another kind of weed killer herbicide---the binary mix preparation that fluroxypyr is composite; This Herbicidal combinations can not only improve the preventive effect of medicament to weeds, and to when stubble and succession crop safety, has reduced drug cost simultaneously.
The object of the present invention is to provide a kind of mixed herbicidal composite that contains two careless ethers and fluroxypyr.
Another object of the present invention is to provide a kind of mixed herbicidal composite that contains two careless ethers and fluroxypyr to be used for the application of the weed killer herbicide of agent for removing grass in paddy field in preparation.
The object of the invention is realized through following technical scheme:
A kind of mixed herbicidal composite that contains two careless ethers and fluroxypyr, it is that this Herbicidal combinations is main active ingredient with two careless ethers and fluroxypyr, the mass ratio of two careless ethers and fluroxypyr is 0.1～99: 0.1～99.The mass ratio of preferred two careless ether and fluroxypyr is 1～50: 1～50.The mass ratio of two careless ethers and fluroxypyr further is preferably 1～30: 1～20 in the Herbicidal combinations of the present invention, most preferably is 1～10: 1～10.
The above-mentioned mixed herbicidal composite that contains two careless ethers and fluroxypyr, the two quality percentage composition in Herbicidal combinations of two careless ethers and fluroxypyr is 1～85%, the preferred mass percentage composition is 10～80%.
The above-mentioned mixed herbicidal composite that contains two careless ethers and fluroxypyr, it is with two careless ethers and fluroxypyr is that the auxiliary agent that allows on main active ingredient and the agricultural chemicals is mixed with any one formulation.Promptly except two kinds of active ingredients, can also add different surfaces activating agent, thickener, solvent or solid packing etc., the formulation that can be processed into is preferably missible oil, suspending agent, water dispersible granules, wetting powder.
The mixed herbicidal composite that contains two careless ethers and fluroxypyr of the present invention mainly is used for preparing the weed killer herbicide of the postemergence weed control that is applied to paddy field, and this weed killer herbicide can be prevented and kill off various annual weed and perennial weed effectively.Especially can improve preventive effect to multiple grassy weed and broad leaved weed.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal combinations of the present invention can kill weeds through two kinds of different mechanism, makes weeds resistance generation speed reduce, and greatly improves the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Two careless ethers are broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and fluroxypyr is mainly to be the weed killer herbicide of preventing and kill off broad leaved weed.After both mixed, can improve had preventive effect to multiple annual gramineous weed and broad leaved weed, thereby has prolonged the lasting period of medicament.
3, safe.Because its using dosage is under control, and makes medicament under the prerequisite that has improved drug effect, its safety to paddy field and succession crop also is improved.
