Abstract
The invention belongs to the field of the pesticide, relating to a hybrid weeding composite containing Bispyribac-sodium and oxaziclomefone. The hybrid weeding composite takes the Bispyribac-sodium and the oxaziclomefone as main effective ingredients with the mass ratio of (1-99):(1-99). In the weeding composite disclosed by the invention, different surfactants, thickeners, solvents or solid fillers and the like can be added to be processed into various dosage forms, such as missible oil, a suspending agent, water dispersible granules, wettable powder and the like. The weeding composite can be used for preventing and removing paddy field grass family weeds, broad leaf weeds and cyperaceae weeds. On the premise of improving pesticide effect, the weeding composite can delay weed resistance, has the advantages of wide weeding spectrum and long effect lasting period if being compared with a single agent, is safe to the paddy and next batch of crop and is an ideal paddy field herbicide.
Description
Technical field
The invention belongs to pesticide field, especially the weed killer herbicide field relates to a kind of couple careless Mi that contain with the mixed herbicidal composite of oxazine humulone.This Herbicidal combinations can be used the paddy field postemergence weed control.
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:
The oxazine humulone has another name called the barnyard grass peace, chemical name: 3-[1-(3, the 5-dichlorophenyl)-1-Methylethyl]-2,3-dihydro-6-methyl-5-phenyl-4H-1,3-oxazine-4-ketone.This weed killer herbicide belongs to oxazine ketone new herbicides, and the mechanism of action is that comparison is unique, is different from the mode of action of other weed killer herbicides, the inner sucting conduction type herbicide for paddy field, and main controlling object is multiple weeds such as barnyard grass grass, waterwort, moleplant seed, difformed galingale herb; Have low, the suitable dispenser phase of active ingredient usage amount long, the lasting period is long, to the selection safety of paddy rice than characteristics such as height.To the succession crop wheat, barley, carrot, Chinese cabbage, onions etc. have no adverse effects.
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 the complementary two careless Mi of pluses and minuses with the oxazine humulone is 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 Mi Yu the composite binary mixed herbicidal composite of oxazine humulone; This Herbicidal combinations can not only improve the preventive effect to weeds, and to when stubble and succession crop safety, has reduced peasant's drug cost simultaneously.
The purpose of this invention is to provide a kind of mixed herbicidal composite that contains two careless ethers and oxazine humulone, it is characterized in that this Herbicidal combinations is main active ingredient with two careless ethers and oxazine humulone, the mass ratio of two careless ethers and oxazine humulone is 1～99: 1～99.Preferred two careless Mi is Yu the mass ratio of oxazine humulone is 1～60: 1～60, and two careless Mi are Yu the mass ratio of oxazine humulone further is preferably 1～40: 1～40, and most preferably mass ratio is 1～20: 1～20.
In mixed herbicidal composite, two careless Mi are Yu the two quality percentage composition in Herbicidal combinations of oxazine humulone is 1～85%, and the preferred mass percentage composition is 10～80%.
Two careless Mi of the present invention is with in the binary built preparation of oxazine humulone; Except two kinds of active ingredients; Can also add the auxiliary agent that allows on the agricultural chemicals such as different surfaces activating agent, thickener, solvent or solid packing, be processed into multiple formulations such as missible oil, suspending agent, water dispersion granule, wetting powder.
This Herbicidal combinations can delay the weeds resistance with respect to single agent under the prerequisite that has improved drug effect, herbicidal spectrum is wide, and the lasting period is long, enough prevents and kill off paddy field annual gramineous weed, broad leaved weed and sedge weed, and to paddy rice and second stubble crop safety.Herbicidal combinations of the present invention can be used for preparing the weed killer herbicide of paddy field postemergence weed control; Can be used in preparation especially and prevent and kill off the weed killer herbicide of various annual weed and perennial weed, especially can prepare the weed killer herbicide of preventing and kill off grassy weed, 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 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 ， oxazine humulone to annual gramineous weed is mainly to be the weed killer herbicide of grassy weed and sedge weed.Both can improve the preventive effect that has of multiple annual gramineous weed, broad leaved weed and sedge weed, thereby prolong the lasting period of medicament after mixing.
3, safe.Medicament of the present invention is under the prerequisite that has improved drug effect, and its safety to paddy field and succession crop also is improved.
