Abstract
The invention relates to a weedicide composition, which comprises the following active ingredients in part by weight: 1 to 99 parts of metamifop, 1 to 99 parts of cyhalofop butyl ester and 1 to 99 parts of dithiopyr. The invention also relates to the use of the weedicide composition in the prevention and control of ephemeral and perennial broadleaf weed and gramineous weed in rice fields. The weed control effect of the weedicide composition of the invention is much higher than that of a signal preparation and the synergetic effect of the weedicide composition is very good; the usage amount of the medicinal preparation is reduced, so the medicinal cost of peasants as well as influences on the environmental are reduced; meanwhile, the weed-killing spectrum is broadened and the generation and development of resistance to the signal preparation are delayed effectively.
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 metamifop, cyhalofop-butyl, three kinds of active components of dithiopyr.
Background technology
Metamifop (metamifop) is fragrant phenoxy esters of gallic acid (AOPP) weed killer herbicide, can suppress the ACC enzyme, promotes vegetable fatty acid synthetic.It is as a kind of acetyl-CoA carboxylase (ACCase) inhibitor, can prevent and kill off admirably most of annual gramineous weeds, different from most of AOPP class weed killer herbicides is, metamifop is to rice safety, can effectively prevent and kill off the paddy field main weeds, such as barnyard grass, moleplant seed, lady's-grass and eleusine indica, be mainly used in transplanting the weeding with direct sowing rice field.
Cyhalofop-butyl is unique in the fragrant phenoxy phenoxy propionic acid weed killer herbicide paddy rice to be had the kind of tight security.Cyhalofop-butyl also is interior suction conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, the phloem conduction, accumulate the 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 at last plant dead.The cyhalofop-butyl speed of action is slower, generally needs to make in 1～3 week weeds dead.In the paddy rice body, cyhalofop-butyl can be degraded to rapidly the diacid attitude to the acetyl-CoA carboxylase non-activity, thereby cyhalofop-butyl has the safety of height to paddy rice.Because cyhalofop-butyl is degraded in water and soil rapidly, to succession crop safety.
Dithiopyr is picolinic acid class preemergence herbicide, the impact that activity of weeding is not changed by environmental factor (temperature, soil types and moisture), and to rice safety, the lasting period can reach 80 days.
Yet above-mentioned three kinds of weed killer herbicides use separately general to the integrated control effect of the annual and perennial broad leaved weed of paddy field and grassy weed, 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 metamifop, cyhalofop-butyl, three kinds of active components of dithiopyr.
Another object of the present invention provides 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:
Metamifop 1～99
Cyhalofop-butyl 1～99
Dithiopyr 1～99;
Preferably, described herbicidal composition contains the active component of following weight portion:
Metamifop 1～20
Cyhalofop-butyl 1～20
Dithiopyr 1～20.
Wherein, 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

Molecular weight is 401.4, and structural formula is:
One of preferred composition of weed killer herbicide of the present invention 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 admirably most of annual gramineous weeds, different from most of fragrant phenoxy esters of gallic acid weed killer herbicides is, metamifop is to rice safety, can effectively prevent and kill off the paddy field main weeds, such as barnyard grass, moleplant seed, lady's-grass and eleusine indica, be mainly used in transplanting and the direct sowing rice field weeding.
Another preferred composition cyhalofop-butyl of weed killer herbicide of the present invention is unique in the fragrant phenoxy phenoxy propionic acid weed killer herbicide paddy rice to be had the kind of tight security.Cyhalofop-butyl is interior suction conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, the phloem conduction, accumulate the 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 at last plant dead.The cyhalofop-butyl speed of action is slower, generally needs to make in 1～3 week weeds dead.In the paddy rice body, cyhalofop-butyl can be degraded to rapidly the diacid attitude to the acetyl-CoA carboxylase non-activity, thereby cyhalofop-butyl has the safety of height to paddy rice.Because cyhalofop-butyl is degraded in water and soil rapidly, to succession crop safety.
Another preferred composition dithiopyr of weed killer herbicide of the present invention is picolinic acid class preemergence herbicide, the impact that activity of weeding is not changed by environmental factor (temperature, soil types and moisture), and to rice safety, the lasting period can reach 80 days.
Because above-mentioned three kinds of compositions have different structure types and mechanism of action, the three is composite can to improve to a greater degree to paddy field malignant weed preventive effect, can enlarge the herbicide spectrum.

The purpose of this test example is to study the synergistic effect that metamifop, cyhalofop-butyl, dithiopyr are used with.
One, materials and methods
1. medicament: metamifop, cyhalofop-butyl, dithiopyr and three's different proportion sample;
2. give birth to survey for the examination weeds: be broad leaved weed or the grassy weeds such as barnyard grass, lady's-grass, the root of Beijing euphorbia, Commelina communis for the examination weeds, weed seed is provided by China Agricultural University, selects that maturity is good, neat and consistent, germination rate be for subsequent use 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 processes.
Test be the test special soil collected of medication plot not with soil, gets bore 9.5cm, dark 6cm flowerpot, and soil is filled to 3/4 highly.Add water after soil is fully moistening, each is sown in the flowerpot for the 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 regularly moisturizing is to keep soil moisture to suit, and temperature is between 20 ℃～30 ℃ in the greenhouse, and air humidity is more than 50%.Weeds emerge rear thinning, decide strain, weeds grow to 2～2.5 leaves automatically spray with 3WPSHZ-500 during the phase tower (Nanjing agriculture mechanical investigations institute) carry out bud after the cauline leaf spraying process.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.Process in the rearmounted greenhouse and grow, keep soil moisture content 100% with the moisturizing of bottom-irrigating mode 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 simultaneously the part weeds to measure the acrial part fresh weight.
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 metamifop, cyhalofop-butyl, dithiopyr and the three's different proportion co-toxicity coefficient measurement result that is mixed
Annotate: co-toxicity coefficient＞120 expression synergy.
