Description
Technical field
The invention belongs to agriculture plant protection field, more particularly to a kind of Herbicidal combinations for having and improving performance.
Background technology
Huo Zu Fen metamifops (metamifop) are the fragrant phenoxy propionic acid developed by Chemical Engineering Technology research institute of South Korea
Ester herbicide, can be fabulous prevent and kill off most of annual gramineous weeds, unlike most of such herbicides, oxazole
Acyl grass amine can effectively prevent and kill off rice terrace main weeds, such as barnyard grass, moleplant seed, lady's-grass and eleusine indica, be mainly used in rice safety
Transplanting and direct sowing rice field weeding.Metamifop low toxicity, it is environmentally safe, there is extensive miscibilty, and be expected to be used for other works
Thing and Kill weeds, it is a very promising herbicide.
The chlorine (Chipton) of 2 first of active component 4 and its derivative category phenoxy carboxylic acid selective herbicide, have stronger
Uptake and translocation, it is mainly used in after seedling cauline leaf process, medicament passes through cuticula and cytoplasma membrane, is finally transmitted to each several part,
Different parts suppress nucleic acid metabolism and the synthesis of protein to nucleic acid and the synthetically produced Different Effects of protein, in plant tip,
Growing point is set to stop growing, young leaflet tablet not tensible, until photosynthesis can not be normally carried out；It is transmitted to plant bottom
Medicament, make the synthesis increase of nucleic acid and protein that plant stem organizes, promote abnormal cell division, the tip of a root expands, and loses and inhales
The ability adopt point, cane distortion, deformity are caused, screen casing is blocked, and bast destroys, and organic matter transport is obstructed, and is planted so as to destroy
The normal viability of thing, ultimately results in Plant death.It is widely used in wheat paddock, corn field, rice terrace, urban lawn, fiber crops
Class crop prevents and kill off annual or perennial broadleaf weed and part nutgrass flatsedge；It is mixed with glyphosate to prevent and kill off resistant weed, accelerate herbicide
Speed effect is obvious；Also there is data introduction, taking off root agent as rice uses, and can improve effect of pulling up seedlings.For soil treatment, to one
The perennial weeds young shoot of year raw dogstail and seminal propagation also has certain preventive effect.
Actual agricultural chemicals experience have shown that, repeat and single-minded carry out controlling weeds in many feelings using a kind of reactive compound
The fast selective of weeds will be caused under condition, prevent and treat injurious weed usually using the mixture of different activities compound at present.
By the way that the reactive compound with the different mechanisms of action is combined, can delaying drug resistance produce, reduce amount of application, reduce preventing and treating
Cost.
The content of the invention
The purpose of the present invention is to be directed to herbicide resistance and pedo relict problem in actual applications, is filtered out containing two
The herbicide of the different weeding principles of kind is compounded, and to improve herbicide prevention effect, delaying drug resistance produces, and reduces amount of application,
Reduce cost accounting.
It is a further object of the present invention to provide above-mentioned composition agriculture field controlling weeds application.
The purpose of the present invention can be reached by following measures：
The invention provides a kind of Herbicidal combinations with synergistic effect, contain effective constituents A and B in said composition,
Effective constituents A Wei metamifops, active ingredient B are the chlorine of 2 first 4 and its derivative.
The suitable chlorine derivative of 2 the first 4 preferably chloric acid of 2 first 4, the different monooctyl ester of the chlorine of 2 first 4, the chlorine sylvite of 2 first 4, the chlorine sodium salt of 2 first 4,2 potassium
One kind in 4 chlorine diformazan ammonium salts or the chlorine isopropyl amine salt of 2 first 4, the different monooctyl ester of the further preferred chlorine of 2 first 4.
Inventor is found by experiment that above-mentioned Herbicidal combinations synergy is obvious, it is often more important that amount of application is reduced, and reduction makes
Contain that component A is different from component B compound structure type, and mechanism of action is different with cost, both can expand weeding at compounding
Spectrum, and generation and the development speed of Weed Resistance can be delayed to a certain extent, and no interactions between component A and component B
Resistance.
The active ingredient of the present composition only can include A and B, can also not influence the base of composition overall performance
On plinth, further comprising other active ingredients.
In a kind of scheme, the effective constituents A of Herbicidal combinations of the present invention and B weight ratio are 10~1：1~30.It is a kind of
