Abstract
The invention relates to an agricultural chemical compound herbicide used for one-time preventing and removing of monocotyledonous and dicotyledonous weeds in cornfields. Clodinafop acid and fluroxypyr are compounded to made into powder, pelletized granule, suspending agent, dry suspending agent, missible oil, and the like under the actions of the corresponding auxiliary agent and safener, and the mass ratio of the active component of the clodinafop acid and the fluroxypyr herbicide is 1 to 90 : 90 to 1. Compared with the single reagent, the herbicidal activity is improved after compounding, and the weed control spectrum is extended, and the invention is safe to the crops.
Description
Technical field
The present invention relates to a kind of cornfield herbicidal composition, its active component is combined by alkynes oxalic acid and fluroxypyr.
Technical background
Alkynes oxalic acid commodity are called the top wheat utmost point of claiming again; English general by name, the Clodinafop-Propargyl chemical name: (R)-and 2-[4-(5-chloro-3-fluoro-2-pyridine oxygen is promptly) phenoxy group] propionic acid propargyl ester, CAS number: 105512-06-9; International name:, structural formula is:
Inhaling the conductivity weed killer herbicide in alkynes oxalic acid belongs to, is the improved seeds in the weed killer herbicide, and efficient, low toxicity, low-residual can effectively be prevented and kill off monocotyledon weed like amur foxtail, wild oat, hard grass, Chinese silvergrass, annual bluegrass etc., but poor to the broadleaf weed preventive effect.Alkynes oxalic acid still can be brought into play better drug effect when low temperature, and to second stubble crop safety.
The fluroxypyr trade name makes it grand, English common name: fluroxypyr, and chemical name: 4-amino-3,5-two chloro-6-fluoro-pyridines-2-pyridine fluoroacetic acid 1-methyl-heptyl ester molecule formula: C15H21C12FN2O3, structural formula:
Fluroxypyr also is a kind of interior conduction herbicide after seedling of inhaling.Very soon by plant absorbing, can be combined into conjugates and lose toxicity, thereby have selectivity behind the medicine.Generally the drug effect performance is slower when temperature is low, in soil the half life period shorter, can not exert an influence to a following batch broad leaf crop.Therefore, to the characteristics of two kinds of weed killer herbicides, we have invented this Herbicidal combinations.
Summary of the invention
Goal of the invention: design a kind of wheatland and can either prevent and kill off monocotyledon weed, again can be to the compound herbicide of broadleaf weed, and the composition low toxicity, efficient, to crop safety, succession crop there is not influence.
Design: in order to realize above-mentioned purpose of design.We test and adopt alkynes oxalic acid and fluroxypyr composite, prevent and kill off the whole weeds of wheatland.Specifically; As active component, wherein, the weight ratio of described active component is 1～90: 90～1 to the present composition alkynes oxalic acid and fluroxypyr; Preferred both weight ratio is 1～10: 20～5, and most preferred both weight ratios are 1～3: 12～8.The weight percentage of active component in weeding combination is 1%～99%, preferably 15%～80%.
It is active that Herbicidal combinations of the present invention has excellent Herbicidal synergistic.
The present invention combination can convert conventional formulation such as pulvis, granule, suspending agent to, dry suspending agent, missible oil etc., and administration form depends on specific use; Under various situation, must guarantee that their dispersion is trickle as much as possible and even.
These preparations can use the mode of known conventional to prepare; Be made up of active component and auxiliary element, wherein auxiliary element safener, surfactant, tackify rheological agent, antifreezing agent, carrier filler also comprise acceptable stabilizing agent, colouring agent or the like in the pharmaceutical formulation.
Wherein safener comprises fenchlorazole, mefenpyrdiethyl; Surfactant comprises that calcium dodecyl benzene sulfonate, lauryl sodium sulfate, sodium lignin sulfonate (calcium), polyethenoxy ether carboxylate, alkylnaphthalene sulfonate, phenethyl phenol APEO phenethyl phenol polyoxy second are at ether polyoxypropylene ether block copolymers, NPE, AEO, castor oil polyoxyethylene ether; The tackify rheological agent comprises xanthans, sodium carboxymethyl starch, methylcellulose, white carbon, aluminium-magnesium silicate, (crosslinked) polyvinylpyrrolidone; Antifreezing agent comprises ethylene glycol, propane diols, glycerine, urea; Carrier filler comprises kaolin, bentonite, attapulgite, precipitated calcium carbonate, diatomite, sodium sulphate, ammonium sulfate, water, organic solvent, vegetable oil.
Usually, composition contains 1% to 90% active component by weight, and usually according to the difference of preparation type, preferred content is 15% to 80% active component by weight.
Present composition application dosage, the difference according to factors such as crop sequences, time of application, weather conditions is generally 10-200g a.i./ha, is preferably 30-120g a.i./ha.The general foliage applying that adopts, for example leaf and the processing of spraying.
Herbicidal combinations of the present invention can be applied to prevent and kill off in the wheat paddock grassy weed and broad leaved weed.
Beneficial effect
Compared with present technology the present invention has following characteristics:
1. broad weed-killing spectrum.Two compounds combination back enlarges kills the grass spectrum, can disposablely prevent and kill off big Tanaka grassy weed and broad leaved weed,, clearvers careless to annual bluegrass, hard grass, caput, deceives malignant weeds such as grass, wartwort, field bindweed special efficacy is arranged.
2. high to crop safety.Herbicidal combinations toxicity of the present invention is low, and weak sensitization is low to crop, people and animals' murder by poisoning.Can be under the situation that does not injure crop, management of weeds safely.
3. the weed control synergistic effect is remarkable.The present invention is a compound formulation, and the usage amount that makes two kinds of weed killer herbicides reduces during all than single use, thereby has improved herbicidal effect, reduced cost, has reduced environmental pollution.
4. save the labour.Compound formulation of the present invention is with compound alkynes oxalic acid and the combination of compound fluroxypyr.Utilized alkynes oxalic acid to the preventive effect of grassy weed and fluroxypyr to the preventive effect of broad leaved weed, can play a drug, the wealthy two effects of removing of standing grain are saved the labour, increase the benefit.
