Abstract
The invention relates to a herbicide composition, which contains the following active ingredients in part by weight: 0.5 to 95 parts of cyhalofop-butyl and 0.5 to 95 parts of metamifop. The invention also relates to application of the herbicide composition in preventing and controlling annual and perennial broadleaf weeds and gramineous weeds of paddy fields. The weeding effect of the herbicide composition is remarkably improved compared with a single agent; and the herbicide composition shows extremely good synergistic effect, reduces the consumption of the agents, reduces the influence on the environment at the same time of reducing the medicament cost of peasants, meanwhile, enlarges the weeding spectrum, and can effectively delay the occurrence and development of single agent resistance.
Description
Technical field
The present invention relates to the agricultural herbicide field, specifically, relate to a kind of herbicidal composition and application thereof that contains cyhalofop-butyl and two kinds of active components of metamifop.
Background technology
Cyhalofop-butyl is unique in the fragrant phenoxy propionic acid class weed killer herbicide paddy rice to be had the kind of tight security.In belonging to, inhales cyhalofop-butyl the conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, the phloem conduction, accumulate meristem zone in plant corpus, suppress acetyl-CoA carboxylase, fatty acid is synthesized stop, the growth division of cell can not normally be carried out, film system etc. contains the fat structural deterioration, causes plant death at last.The cyhalofop-butyl speed of action is slower, generally needs for 1～3 week made weeds death.In the paddy rice body, cyhalofop-butyl can be degraded to the diacid attitude to the acetyl-CoA carboxylase non-activity rapidly, thereby cyhalofop-butyl has the safety of height to paddy rice.Because cyhalofop-butyl is degraded in water and soil earth rapidly, to succession crop safety.
Metamifop (metamifop) is fragrant phenoxy esters of gallic acid (AOPP) weed killer herbicide, can suppress the ACC enzyme, can promote vegetable fatty acid synthetic.It is as a kind of acetyl-CoA carboxylase (ACCase) inhibitor, can prevent and kill off most of annual gramineous weeds admirably, different with most of AOPP class weed killer herbicides is, metamifop is to rice safety, can effectively prevent and kill off the paddy field main weeds, as barnyard grass grass, moleplant seed, lady's-grass and eleusine indica, be mainly used in and transplant and the direct sowing rice field weeding.
Yet above-mentioned two kinds of weed killer herbicides use general to the integrated control effect of annual and perennial broad leaved weed of paddy field and grassy weed separately, can't reach optimum herbicidal effect.
Summary of the invention
The purpose of this invention is to provide a kind of herbicidal composition that contains cyhalofop-butyl and two kinds of active components of metamifop, this herbicidal composition has enlarged grass spectrum extremely, and has improved herbicidal effect, has reduced using dosage.
Another object of the present invention is to provide the application of described herbicidal composition.
In order to realize purpose of the present invention, the present invention discloses a kind of herbicidal composition, and it contains the active component of following weight portion:
Cyhalofop-butyl 0.5-95
Metamifop 0.5-95;
Preferably, described herbicidal composition contains the active component of following weight portion:
Cyhalofop-butyl 1～20
Metamifop 1～20.
Wherein, the chemical name of described cyhalofop-butyl is (R)-2-[4-(4-itrile group-2-fluorophenoxy) phenoxy group] butyl propionate, its molecular formula is C

4, relative molecular weight is 357.4, structural formula is:
The chemical name of described metamifop is (2R)-2-[4-[(6-chloro-2-Ben oxazolyl)] phenoxy group]-N-(2-fluorobenzene)-N-methyl propanamide, its molecular formula is C

One of the preferred composition of weed killer herbicide of the present invention cyhalofop-butyl is unique in the fragrant phenoxy propionic acid class weed killer herbicide paddy rice to be had the kind of tight security.In belonging to, inhales cyhalofop-butyl the conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, the phloem conduction, accumulate meristem zone in plant corpus, suppress acetyl-CoA carboxylase, fatty acid is synthesized stop, the growth division of cell can not normally be carried out, film system etc. contains the fat structural deterioration, causes plant death at last.The cyhalofop-butyl speed of action is slower, generally needs for 1～3 week made weeds death.In the paddy rice body, cyhalofop-butyl can be degraded to the diacid attitude to the acetyl-CoA carboxylase non-activity rapidly, thereby cyhalofop-butyl has the safety of height to paddy rice.Because cyhalofop-butyl is degraded in water and soil earth rapidly, to succession crop safety.
Another preferred composition metamifop (metamifop) of weed killer herbicide of the present invention is fragrant phenoxy esters of gallic acid (AOPP) weed killer herbicide, can suppress the ACC enzyme, can promote vegetable fatty acid synthetic.It is as a kind of acetyl-CoA carboxylase (ACCase) inhibitor, can prevent and kill off most of annual gramineous weeds admirably, different with most of AOPP class weed killer herbicides is, metamifop is to rice safety, can effectively prevent and kill off the paddy field main weeds, as barnyard grass grass, moleplant seed, lady's-grass and eleusine indica, be mainly used in and transplant and the direct sowing rice field weeding.
Because above-mentioned two kinds of compositions have different structure types and mechanism of action, both are composite can to improve to a greater degree to paddy field malignant weed preventive effect, can enlarge to kill the grass spectrum.
In the herbicidal composition of the present invention, the weight percentage of described active component is 0.1～96%; The content of active component depends on the amount of application when every kind of component is used separately in the herbicidal composition of the present invention, also depends on the ratio of a kind of component and another kind of component and the degree of synergistic effect.

The purpose of this test example is to study the synergistic effect that cyhalofop-butyl and metamifop are used with.
One, material and method
1. medicament: cyhalofop-butyl, metamifop and the two different proportion sample;
2. give birth to survey for the examination weeds: for the examination weeds is broad leaved weed or grassy weeds such as barnyard grass grass, lady's-grass, the root of Beijing euphorbia, Commelina communis, and weed seed is provided by China Agricultural University, selects that maturity is good, neat and consistent, germination rate be standby at the seed more than 90%;
3. test method: the greenhouse pot culture method is adopted in test, under each dosage weeds is carried out the cauline leaf spraying and handles.
Test is the special-purpose soil of test of not medication plot collection with soil, gets bore 9.5cm, dark 6cm flowerpot, and soil is filled to 3/4 height.After adding water and treating that soil is fully moistening, each is broadcast in the flowerpot for examination weed seed, every kind of weeds guarantee 15～20 seeds, and percentage of seedgermination is 70～90%.After planting, cover the thick mixed husky fine earth of 0.5～1.0cm, the bottom adds the water mode makes that soil suction is saturated to be placed on the incubation growth greenhouse in, and moisturizing regularly suits to keep soil moisture, and temperature is between 20 ℃～30 ℃ in the greenhouse, and air humidity is more than 50%.Weeds emerge the back thinning, decide strain, grow to the cauline leaf spraying processing after full-automatic spray tower (Nanjing agricultural machinery research institute) carries out bud with 3WPSHZ-500 during the phase of 2～2.5 leaves in weeds.The long-pending 0.097m of sprayer unit spray powder
2, amount of liquid medicine 10ml, operating pressure 0.2MPa liquid measure 40%.4 repetitions are established in every processing, and other establishes blank.Handle in the rearmounted greenhouse and grow, keep soil moisture content 100% with bottom irrigation method moisturizing every day.Regularly observe the plant reaction symptom, behind medicine, pressed the comprehensive activity of weeding of 0-100% staging visual assessment in 15 days, select the part weeds to measure the acrial part fresh weight simultaneously.
Two, result of the test
Adopt the SPSS software analysis, obtain virulence equation, LC
50Value (mg/L) and co-toxicity coefficient the results are shown in Table 1.
Table 1 cyhalofop-butyl, metamifop and the two different proportion co-toxicity coefficient measurement result that is mixed
