Description
Technical field
The present invention relates to technical field of pesticide, more particularly to one kind for preventing and kill off cornfield gramineae weed, broad leaved weed
The composition pesticide containing isoproturon, flucarbazone and diflufenican.
Background technology
Wheat weeds endanger the production for directly affecting wheat crops, are the key factors for restricting crop yield.Prevent and kill off wheat
Field crop smothering is the vital task for developing Wheat Production.The use of chemical herbicide is the one of the important signs that of agricultural modernization.Mesh
Preceding wheat weeds are prevented and kill off mainly based on aryloxyphenoxypropanoates class herbicide cauline leaf spraying after weeds seedling.Although for not same order
There are many sections, and herbicide kind is available, but most of kind is difficult to ensure a drug and keeps in crop entire breeding time
Without grass.Therefore from the point of view of economy, environmental angle, grope to probe into wheat paddock first use and keep in crop entire breeding time without grass
Safe efficient herbicide seem particularly urgent.
Isoproturon, chemical name：3- (4- isopropyl phenyls) -1,1- dimethyl ureas or -3- are to cumenyl -1,1- dimethyl
Urea.Belong to phenyl ureagroup herbicides, mainly absorbed by root and cauline leaf and inhibit photosynthesis electron transmission, for before selective seedling, seedling
Herbicide afterwards also has selection systemic action；Isoproturon is efficient, broad-spectrum herbicide, can be applied to wheat, corn, rice etc.
Grass family and broad leaved weed are prevented and kill off in the crop fields.
Diflufenican, chemical name：2 ', 4 '-two fluoro- 2- (methylphenoxy between a, a, a- trifluoro) -3- pyridine acyl benzene
Amine.Belong to acetamide-group herbicides, can be absorbed by weed bud and root system, be conducted in plant body, carotenoid biology is inhibited to close
At, so as to cause weed bud decolourize or bleach.It is miscellaneous that diflufenican can effectively prevent and kill off barley, wheat, the grass family of rice terrace
Grass and broad leaved weed.
Invention content
The purpose of the present invention：Solve the problems, such as existing herbicide develop immunity to drugs to farmland weed, single use control effect
Poor, first use is difficult to the problem of effectively controlling Weed infestation in wheat entire breeding time, and the object of the present invention is to provide one
Kind of the composition pesticide containing isoproturon, flucarbazone and diflufenican, make it have efficiently, it is wide spectrum, environmentally friendly, be conducive to
The features such as wheat weeds comprehensive treatment.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of composition pesticide containing isoproturon, flucarbazone and diflufenican, including active constituent and auxiliary at
Point, the active constituent be isoproturon, flucarbazone and diflufenican, isoproturon, flucarbazone and diflufenican matter
Amount is than being 1:1.2-1.8:1-2；The mass percentage that the isoproturon, flucarbazone and diflufenican account in composition is
5-80%；The auxiliary element includes at least one of dispersant, emulsifier, wetting agent, binder, antifreezing agent, thickener.
Further, the mass ratio of the isoproturon, flucarbazone and diflufenican is 1:1.5:1.6.
Further, it is 20- that the isoproturon, flucarbazone and diflufenican, which account for the mass percentage in composition,
80%.
Further, the dispersant be alkyl phenol polyoxyethylene ether, alkylphenol-polyethenoxy base ether formaldehyde condensation products and
The mixture of modified naphthalene sulfonate, mass ratio 1:1.2-1.6:1.5-3.
Further, the emulsifier is bisphenol ethyl phenol polyoxyethylene ether, phenethyl phenol polyethenoxy ether 600# and gathers
The mixture of ethylene oxide sorbitan fatty acid ester, mass ratio 1:0.8:1.2.
Further, the antifreezing agent is the mixture of dimethyl sulfoxide (DMSO), urea and thiocarbamide, mass ratio 0.3:1:
0.5。
Further, the dosage form of the composition pesticide is wettable powder, water dispersible granules, suspending agent, microemulsion, oil
Agent, suspension emulsion, missible oil, aqueous emulsion or oil-suspending agent.
A kind of composition pesticide containing isoproturon, flucarbazone and diflufenican prevention cornfield gramineae weed,
Application in broad leaved weed.
Further, it when preventing cornfield gramineae weed, broad leaved weed, is used before broadcasting rear seedling or after broadcasting before 3 leaf phases.
Flucarbazone, chemical name 1H-1,2,4- triazole -1- carbamyl -4,5-2H-3- methoxyl group -4- methyl -5-O-
N- [[2- (trifluoro methoxy) benzene] sulphonyl]-sodium salt.Belong to sulfonylurea internal-suction type efficient wheat field herbicidal, it can be by the root of weeds
With cauline leaf absorb, by inhibit weeds body in acetolactate synthestase activity, destroy the normal Physiological and Biochemical Metabolism of weeds and
Play activity of weeding.Wheat paddock major part grassy weed can be effectively prevented and kill off, while also can effective control section broad leaved weed.Its
It can be metabolized quickly in wheat body, there is fabulous safety to wheat.
The beneficial effects of the invention are as follows：Compared with existing product, of the invention containing isoproturon, flucarbazone and pyrrole fluorine acyl grass
The composition pesticide of amine, has the following advantages that：
1) composition pesticide containing isoproturon, flucarbazone and diflufenican of the invention, within a certain ratio range
Synergistic effect is shown, the control effect of composition is significantly improved than single dose, reduces the dosage of pesticide, reduces
Pesticide use number, reduces drug cost, reduces adverse effect of the pesticide to ecological environment, is conducive to keep ecology flat
Weighing apparatus.
2) composition pesticide containing isoproturon, flucarbazone and diflufenican of the invention, the group of three kinds of active ingredient
It closes, expands herbicide controlling spectrum, not only sealed but also killed, a drug can effectively control Weed infestation in wheat entire breeding time, can make up
Single dose uses defect and limitation.
3) composition pesticide containing isoproturon, flucarbazone and diflufenican of the invention, active ingredient mechanism of action
It is different, the shortcomings that certain product of long-term single use can be overcome to easy to produce resistance, the service life of medicament is extended,
It is of great importance to Weed Resistance comprehensive treatment.
4) composition pesticide containing isoproturon, flucarbazone and diflufenican of the invention, the lasting period is long, not only sealed but also
It kills, easy to use, saving of work and time is fool proof to wheat, is easy to peasant's grasp.
