Description
Technical field
The invention belongs to Synergistic herbicide compositions fields, and in particular to a kind of Herbicidal synergistic containing active components A, B, C
Composition；Wherein A selects propanil, B to be selected from cyhalofop-butyl, and C is selected from the different monooctyl ester of fluroxypyr.
Background technology
Propanil is the highly selective contact killing type herbicide of amides, not only breaks up the photosynthesis of plant, but also is inhibited
Respiration and oxygen public affairs phosphorylation, interfering nucleic acid are synthesized with protein.To make the physiological function of sensitive plant by
It influences, accelerates dehydration, blade gradually dried-up, it is last dead.
Cyhalofop-butyl (cyhalofop-buty) is that uniquely there is height to pacify rice in fragrant phenoxy phenoxy propionic acid herbicide
As complete other kinds of the kind and such of property and uptake and translocation herbicide.It is absorbed by the blade and leaf sheath of plant,
Bast conducts, and accumulation resists acetyl-CoA carboxylase (ACCase), aliphatic acid is made to synthesize in the meristem zone of plant
Stop, the growth division of cell cannot be normally carried out, and the structure containing fat such as membranous system is destroyed, and Plant death is finally resulted in.From cyanogen fluorine
It is slower that careless ester is absorbed into weeds death, generally requires 1-3 weeks, the symptom of weeds after administration is as follows：Four leaf stage it is tender
Bud atrophy, leads to death.The old leaf of two leaf stage changes very little, and keeps green；It is mainly used for preventing and kill off important grassy weed, cyanogen
Fluorine grass ester is efficient to moleplant seed, there is certain preventive effect to low age barnyard grass, can also prevent and kill off, lady's-grass, Paspalum distichum, green bristlegrass, Cowhells
Grass, amur foxtail etc., it is invalid to sedge weed and broad leaved weed.
The different monooctyl ester of fluroxypyr (Fluroxypyr-meptyl) is that pyridine fluoroacetic acid class herbicide is hormone-type weeding
Agent can be kept plant deformity, distortion dead, annual broadleaf weed mainly prevented and kill off, to standing grain by the blade of plant and root Assimilation and conductivity
Undergraduate course weeds are invalid.Pyridine fluoroacetic acid class herbicide type mainly has the different monooctyl ester of fluroxypyr, fluroxypyr, trichlorine
Pyrrole fluoroacetic acid, triclopyr butoxyethyl ester etc..The different monooctyl ester of fluroxypyr or fluroxypyr are suitable for grass
Prevent and kill off the broad-leaveds such as broad leaved weed such as clearvers, chickweed, field bindweed, purslane, water peanut, acalypha copperleaf to section's the crop fields and fruit-bearing forest tea
Weeds, trichlopyr or triclopyr butoxyethyl ester can prevent and kill off shrub lespedeza, aspen, elm, wormwood artemisia, radix bupleuri, campanulaceae, iron
The broad leaved weeds such as line lotus, fern, abrotanum and shrub.
Farmland weed grass is mutually complicated, and type is various, is to prevent and kill off the most effective chemical means of agricultural weed using chemical agent
One of；With the novel pesticide of not cross resistance come to prevent and kill off agricultural weed be a good solution；But one is developed at present
A novel pesticide needs to screen a compounds up to ten thousand, and hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, it is difficult to which that catches up with is upper miscellaneous
The speed that grass develops immunity to drugs；Other methods such as crop structure adjustment, different pesticide rotations etc., in actual mechanical process,
It is difficult to play apparent effect.
Rational chemical herbicide compounding or mixture, which have, expands herbicide controlling spectrum, improves control effect, extends dispenser period, subtracts
Few dosage reduces poisoning risk, reduces residual, delays the advantages that generation and development of weeds drug resistance and drug resistance, so
It is maximally efficient and economic one of the method to solve the above problems selected from suitable mixture of herbicides or mixture；However because agriculture
The mechanism of action is complicated between medicine mixture, and whether synergy is affected by various factors after combination, only relies on experimental result and is subject to
Verification, can not be expected.
Develop new product herbicide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research
Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
The combination of the different monooctyl ester of propanil, cyhalofop-butyl, fluroxypyr has not been reported.
Invention content
