Abstract
The invention relates to an agricultural chemical compound herbicide for once preventing and killing weeds in paddy fields. The agricultural chemical compound herbicide is prepared by compounding fenoxaprop-p-ethyl and bensulfuron methyl, adding a compound safener of mefenpyr-diethyl and 3-benzenesulfonyl-oxazolidine-2-ketone and relative additives, not only expands a weed spectrum and once prevents and kills the weeds in the paddy fields, but also solves the hazard problem of the fenoxaprop-p-ethyl applied to the paddy fields and has wider prospects of market promotion and application.
Description
Technical field
The present invention relates to a kind of agrochemicals compound herbicide of fenoxaprop, be mainly used in the disposable paddy field weed of preventing and kill off, to crop safety, belong to weed killer herbicide and make the field.
Technical background
It is that everybody knows altogether that fenoxaprop is successfully applied to wheat, soybean, beet, flax, peanut, rape, potato and vegetables etc., and its single dose and complex agent type all are successfully applied on these crops.CN1631142, title " good cornfield haulm herbicide ", CN1656895, title " preparation of herbicidal composition suspending agent and application technology " disclose the fine herbicide complex preparation that is mainly used in wheat paddock.The Dan fenoxaprop is applied to paddy field, research both at home and abroad many, actual can successful Application fewer, reason Shi fenoxaprop easily produces poisoning to paddy rice, can suppress paddy growth, makes rice dwarf even large tracts of land withered.For solving drug injury problem, although each research institution is constantly studied, all also there is up till now drug injury problem more or less, so the domestic and international market does not all have the successful formulation of practical application.CN1631143, title " good paddy field haulm herbicide " disclose the herbicidal composition that fenoxaprop is applied to paddy field, but patent do not relate to safener, and actual the use can produce drug injury problem to paddy rice.
Summary of the invention
Purpose of design: design a kind of preventive effect and herbicide spectrum that can either improve fenoxaprop, can solve the drug injury problem that is applied to paddy field again.
Design: in order to realize above-mentioned purpose of design.The application is on weed killer herbicide composite, adopt fenoxaprop as a kind of active component of compound herbicide, adopt sulfonylurea as the built agent of compound herbicide, its design considerations is that the: fenoxaprop can effectively prevent and kill off monocotyledon weed, but to the anti-heterodyne of broadleaf weed, the field exists again single, double cotyledon weeds simultaneously, the single dose Shortcomings, it thoroughly prevents and treats the weed killer herbicide that needs again separately, for remedying the deficiency of single dose, need carry out composite to the single dose weed killer herbicide, so both can improve preventive effect, make things convenient for again the peasant to use, reduce cost.By test, optimize that to have the sulfonylurea herbicide of good preventive effect to carry out to broadleaf weed composite, optimize good stability, the kind of the high and low poison of preventive effect, low-residual, optimize bensulfuron-methyl wherein, entrust Shenyang Chemical Engineering Inst pesticide bioassay center to carry out the proportioning screening test.The result shows that both use with under proper proportion, can enlarge herbicide spectrum, and the part weeds are had the effect of synergy, reaches the purpose that a dispenser prevents and treats full field weed.On this basis, our preferred fenoxaprop and bensulfuron-methyl are mixed in proportion, carry out simultaneously selection and the optimization of C/C composites of safener, carry out drug effect and poisoning comparative test.Particularly preferably mefenpyrdiethyl and 3-benzenesulfonyl-oxazolidines-2-ketone safener, be optimized prescription, reached good effect.
The herbicidal activity that the application chooses becomes to be divided into fenoxaprop, CAS number: 113158-40-0, and international name: Fenoxaprop-p, structural formula is:
Choose simultaneously that broadleaf weed is had the another kind of active ingredient of good preventive effect is the sulfonylurea herbicide bensulfuron-methyl, CAS number: 83055-99-6, international name: Bensulfuron-methy1, structural formula is:
The application carries out fenoxaprop and bensulfuron-methyl composite in proportion, can be processed into various preparations and use, and preferably is processed into wetting powder, aqueous emulsion, the outstanding agent of breast and uses.Add the composite safe agent when composite, wherein a kind of safener is mefenpyrdiethyl, CAS number: 135590-91-9, and international name: Mefenpyr-diethyl, structural formula is:
The another kind of safener that adds when composite is 3-benzenesulfonyl-oxazolidines-2-ketone, and structural formula is:
Technical scheme: a kind of compound herbicide for paddy fields, it contains fenoxaprop (formula I) active component, contains mefenpyrdiethyl (formula III) and 3-benzenesulfonyl-azoles alkane-2-ketone (formula IV) composite safe agent in the compound herbicide,
Fenoxaprop (formula I)
Mefenpyrdiethyl (formula III)
3-benzenesulfonyl-oxazolidines-2-ketone (formula IV).
The present invention compares with background technology, and composition not only contains the composite reactive composition, and is added with the composite safe agent in the composition, both can disposablely prevent and kill off paddy field weed, and low, the environmental protection of cost is again to crop safety, without poisoning.
