Description
Technical field
It is more particularly to a kind of to include pyribenzoxim with improvement performance the invention belongs to agriculture plant protection field
With the Herbicidal combinations of Quizalotop-ethyl.
Background technology
Pyribenzoxim (Pyribenzoxim) is weeding after a kind of novel oxime ester compound, wide spectrum selectivity bud
Agent.Mechanism of action is similar to sulfonylurea and imidazolinone herbicide, belongs to acetolactate synthestase (ALS) inhibitor.It is right
Paddy rice, common wheat, Korea lawn grass have activity of weeding before activity of weeding after selective ultra high efficiency bud, no bud, for prevent and kill off barnyard grass,
The various grassy weeds such as big fringe amur foxtail, polygonum flaccidum and broad leaved weed effect are distinguished, to paddy rice, common wheat safety.
Quizalotop-ethyl (Quizalofop-p-ethyl) be a kind of arylphenoxy phenoxy propionic acid selectivity, inner sucting conduction type,
Cauline leaf process low toxicity herbicide.Absorbed by weeds cauline leaf, the Bidirectional Conduction up and down in plant, be accumulated in top and
Intercalary meristematic, suppresses cell fatty acid synthesis, makes weeds necrosis.There is the selection of height between grassy weed and dicotyledonous crops
Property, there is good preventive effect to the grassy weed in broad leaf crop field.Quizalotop-ethyl work fast, efficacy stability is difficult by rain
The influence of the environmental condition such as temperature water gas and humidity.
Actual agricultural chemicals experience have shown that, repeat and single-minded carry out controlling weeds in many feelings using a kind of reactive compound
It will cause the fast selective of weeds under condition, prevent and treat injurious weed usually using the mixture of different activities compound at present.
, can delaying drug resistance generation, reduction amount of application, reduction preventing and treating by the way that the reactive compound with the different mechanisms of action is combined
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 for planting different weeding principles is compounded, to improve herbicide prevention effect, and delaying drug resistance is produced, and reduces amount of application,
Reduce cost accounting.
It is a further object of the present invention to provide application of the above-mentioned composition in agriculture field controlling weeds.
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 is pyribenzoxim, and active ingredient B is Quizalotop-ethyl.
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
Use cost.Different from component B compound structure type containing component A, mechanism of action is different, and both can expand weeding at compounding
Spectrum, and generation and the development speed of Weed Resistance, and no interactions between component A and component B can be delayed to a certain extent
Resistance.
The active ingredient of the present composition can only include A and B, can also not influence the base of composition overall performance

2nd, drug effect checking test
(1) Assays Example
Using pyribenzoxim as standard agent, disease index and prevention effect are calculated.Prevention effect is converted into probability
It is worth (y), liquor strength (μ g/ml) is converted into logarithm value (x), concentration in calculating virulence equation with least square method and suppress
EC50, the toxicity index and co-toxicity coefficient (CTC) of medicament are calculated according to the abundant methods of Sun Yun.Toxicity test the results are shown in Table 1.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) * 100
A percentage composition+B medicament toxicity index * mixtures in theoretical toxicity index (TTI)=A medicament toxicity index * mixtures
Middle B percentage composition
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] * 100
CTC≤80, composition shows as antagonism, 80 ＜ CTC ＜ 120, and composition shows as summation action, and CTC >=
120, composition shows as synergistic effect.
1st, pyribenzoxim and Quizalotop-ethyl compounding are tested the toxicity test of tongue of sparrow grass
The pyribenzoxim of table 1 compounds with Quizalotop-ethyl different ratio and the toxicity test of tongue of sparrow grass is analyzed
As a result (table 1) shows, pyribenzoxim is with Quizalotop-ethyl in proportioning 20~1：Between 1~30, co-toxicity coefficient exists
More than 142, illustrate that pyribenzoxim compounds preventing and kill off with significant synergistic function to tongue of sparrow grass with Quizalotop-ethyl.
2nd, pyribenzoxim and Quizalotop-ethyl compounding are tested the toxicity test of moleplant seed
