Abstract
The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a mixed herbicide composition containing bispyribac-sodium and acetochlor. The herbicide composition adopts the bispyribac-sodium and the acetochlor as main active components, the weight ratio of the bispyribac-sodium and the acetochlor is 0.1 to 99:0.1 to 99. Different surfactants, thickening agents, solvents, solid fillers or the like can be added to the herbicide composition to become a variety of agents, such as emulsifiable concentrate, suspending agents, water-dispersible granules, wettable powder and the like. Compared with single agents, the herbicide composition delays the resistance of weeds under the premise that the pesticide effect is enhanced, has a broad weeding spectrum and long persistence, can prevent and get rid of gramineous weeds, broadleaf weeds and cyperaceous weeds in paddy fields, is safe for rice and next-stubble crops, and therefore is an ideal paddy field herbicide.
Description
Technical field
This patent belongs to technical field of pesticide, and especially the weed killer herbicide field, relate to a kind of mixed herbicidal composite and application thereof containing two careless ether and Acetochlor.This Herbicidal combinations application paddy field postemergence weed control has remarkable result.
Background technology
Two careless ether, have another name called Nong Meili, salicylic acid Sulfadiazine Compound, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of chemical name: 2,6-.Belong to phenoxy carboxylic acid herbicides, mainly by the acid of root leaf absorption inhibition vinegar milk is synthetic, hindered aminoacid biosynthesis side chain is selective herbicide, rice direct-seeding Tanaka, uses, and herbicidal spectrum is wide.Its structural formula is as follows:
Acetochlor, have another name called metolachlor, standing grain anti-this, grass peace disappears.Chemical name: 2 '-ethyl-6 '-methyl-N-(ethoxymethyl)-2-chloro acetanilide, structural formula is:
This weed killer herbicide is the selectivity preemergence herbicide.Can be absorbed by plant plumule, monocotyledon absorbs by bud scale, dicotyledon hypocotyl Assimilation and conductivity, must dispenser before weeds are unearthed, active ingredient RNA metabolism and protein in plant corpus is synthetic, and young shoot, young root are stopped growing, if moisture suitable young shoot in field is unearthed and is killed, if soil moisture is few, after weeds are unearthed, with soil moisture, increase after weeds absorb medicament and work, grassy weed is to the bent atrophy of leaf roll, other leaf shrinkage, whole strain is withered.High to grassy weed activity such as lady's-grass, the Amaranthus retroflexus sensitivity, the broadleaf weeds such as lamb's-quarters, kitchen garden, black nightshade there is is certain preventive effect and suppress growth, the specific activity grassy weed is low, Soybean Dodder is had to good preventive effect, the drug resistance Crop Acetochlors such as soybean are the non-activity material in the rapid metabolism of body, normally use crop safety.
At present, herbicide for paddy field is limit by crop safety, herbicide spectrum is also limited, uses separately a kind of weed killer herbicide single dose can not control completely effectively the generation of paddy field weed, moreover the weed killer herbicide consumption is excessive or dispenser is inhomogeneous also easily causes the residual hazard to this season crop or succession crop.Therefore, the present invention selects the two careless ether of pluses and minuses complementation and Acetochlor to be made into combination agent to use, so both reduced the consumption of medicament, obviously improved herbicidal effect, has also avoided this season is done to the deposits yields poisoning and to the possibility of succession crop generation residual hazard.
Summary of the invention
The present invention is according to the present situation of current paddy field herbicide after seedling, and after the paddy field seedling weeds a situation arises, provide a kind of by two careless ether and another kind of weed killer herbicide---the binary mix preparation that Acetochlor is composite, this Herbicidal combinations can not only improve the preventive effect of medicament to weeds, and, to when stubble and succession crop safety, reduced drug cost simultaneously.
The object of the present invention is to provide a kind of mixed herbicidal composite containing two careless ether and Acetochlor.
Another object of the present invention is to provide a kind of application of mixed herbicidal composite in the weed killer herbicide for the preparation of agent for removing grass in paddy field containing two careless ether and Acetochlor.
Purpose of the present invention is achieved through the following technical solutions:
A kind of mixed herbicidal composite containing two careless ether and Acetochlor, it is that it is main active ingredient that this Herbicidal combinations be take two careless ether and Acetochlor, the mass ratio of two careless ether and Acetochlor is 0.1～99: 0.1～99.The mass ratio of preferably two careless ether and Acetochlor is 1～40: 1～70.In Herbicidal combinations of the present invention, the mass ratio of two careless ether and Acetochlor more preferably 1～30: 1～30, and the mass ratio of two careless ether and Acetochlor most preferably is 1～10: 1～10.
The above-mentioned mixed herbicidal composite containing two careless ether and Acetochlor, the two quality percentage composition in Herbicidal combinations of two careless ether and Acetochlor is 1～85%, the preferred mass percentage composition is 10～80%.
The above-mentioned mixed herbicidal composite containing two careless ether and Acetochlor, is characterized in that described formulation is wetting powder, water dispersible granules, missible oil or suspending agent.Be in the binary built preparation of two careless ether of the present invention and Acetochlor, 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.
Mixed herbicidal composite containing two careless ether and Acetochlor of the present invention is mainly used to the weed killer herbicide for the preparation of the paddy field postemergence weed control, and this weed killer herbicide can be prevented and kill off various annual weed and perennial weed effectively.Especially can improve the preventive effect to multiple grassy weed and broad leaved weed and sedge 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 by two kinds of different mechanism, makes Weed Resistance produce Speed Reduction, greatly improves the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Two careless ether is the broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and Acetochlor is to be mainly the weed killer herbicide of preventing and kill off annual gramineous weed and part broad leaved weed.Both can improve multiple annual gramineous weed and broad leaved weed are had to preventive effect after mixing, thereby have extended the lasting period of medicament.
3, safe.Because its using dosage is under control, make medicament under the prerequisite that has improved drug effect, its safety to paddy field and succession crop also is improved.
