Abstract
The present invention relates to a kind of Herbicidal combinations and its application, for Herbicidal combinations using flufenacet, diflufenican and mesotrione as principle active component, the weight ratio of flufenacet, diflufenican and mesotrione is 5 60:3‑27:2‑30.For wheat paddock, transplanting rice field before seedling Seal treatment, grassy weed and broad leaved weed are prevented and kill off, synergistic effect is notable.
Description
Technical field：
The invention belongs to agriculture Herbicidal combinations field, is related to one kind and contains flufenacet, diflufenican and mesotrione
Herbicidal combinations.
Technical background：
Flufenacet (Flufenacet), No. CAS is 142459-58-3, be found by Bayer Cropscience Co., Ltd, 1995
The herbicide kind that year is introduced in Britain's Brighton plant protection meeting, belong to aryloxyl acetamide type compound, one can be prevented and kill off extensively
Year raw grassy weed, nutgrass flatsedge and some granule broad leaved weeds.Its action character is：Played a role by suppressing cell division,
Be mainly used in soil treatment, before bud, after bud early stage all can be used, can be widely used for corn, wheat, barley, Soybean and Other Crops field,
Applied in crop before seedling or after seedling early stage, annual gramineous weed such as amur foxtail, Wang grass can be prevented and kill off well, spend more rye
Grass, lady's-grass, barnyard grass, green bristlegrass, and some granule broad leaved weeds such as Descurainia sophia, shepherd's purse, Amaranthus retroflexus, purslane etc..
Diflufenican (Diflufenican), also known as Diflufenican, No. CAS is 83164-33-4.Diflufenican category
In acetamide-group herbicides, the medicine soil layer that anti-leaching can be formed in native table is applied before and after weeds germinate, in crop whole growth period
Keep activity.When weed germination can absorb medicament by medicine soil layer young shoot or root system.The mechanism of action mainly suppresses carotenoids
Plain biosynthesis, cause chlorophyll to be destroyed, cell rupture, weeds is wilted dead.Death rate is relevant with the intensity of light, light
Strong then fast, light is weak then slow.A variety of wheat paddock annual broadleaf weeds, such as clearvers, Veronica, violet can be prevented and kill off.
Mesotrione (mesotrione), also known as mesotrione, chemical name：(2- nitro -4- mesyl benzene adds 2-
Acyl) hexamethylene -1,3- diketone, No. CAS：104206-82-8, it is that Switzerland is first just releasing in recent years up to crop protection Co., Ltd
New herbicides, prevent and kill off annual broadleaf weed and part grassy weed.Mesotrione suppresses p-hydroxypyruvate pair and added
Amino acid Lip river propylhomoserin can be converted into plastoquinone by the activity of oxygenase (HPPD), HPPD.Plastoquinone is phytoene desaturation
The confactor of enzyme.It is the key enzyme of herxheimer-liked reaction.Gone out using 3-5 days implants separate living tissues of mesotrione
Existing yellow symptom causes withered spot therewith, throughout whole plant after fortnight.With faintly acid, in inoic acid soil, energy
Tightly adsorb on organic substance；In neutral or basic soil, exist to be not easy absorbed anionic form.
The content of the invention：
It is an object of the invention to provide a kind of component is reasonable, the resistance to the action of a drug, the low Herbicidal combination of drug cost are not likely to produce
Thing, all there is preferable prevention effect to wheat paddock grass family and broad leaved weed, can be used for wheat paddock, transplanting rice field before seedling
Seal treatment, prevent and kill off grassy weed and broad leaved weed.
In order to solve the above technical problems, present invention offer technical scheme is as follows：

Embodiment
With reference to embodiment to further instruction of the present invention, the percentage in embodiment is weight ratio, but this hair
It is bright to be not limited thereto.
1st, toxicity determines
To further appreciate that synergy of the Herbicidal combinations of the application to weeds, the present inventor is to flufenacet, pyrrole
The mixture of fluorine acyl grass amine and mesotrione has carried out cauline leaf process synergy toxicity measure：
Test material：Clearvers , Wang grass, carp intestines, barnyard grass.
Test method：
A certain amount of weeding active ingredient active compound is weighed, fully after dissolving, single dose mother liquor is configured to respectively, according to mixture mesh
Setting series proportioning, each proportioning sets 5~7 concentration gradients.Representative sensitivity is selected according to single dose herbicide controlling spectrum
Weed seed, cultivate standby to the heart of 3 leaf 1.By after the weeds cauline leaf process for selecting numbering, incubated at room temperature in illumination box is placed on
20 days, prevention effect (fresh weight preventive effect or strain preventive effect) is calculated, dense ED in suppressing then is calculated with least square method50(95% confidence
Limit), then calculate co-toxicity coefficient (CTC) with the abundant methods of Sun Yun.
Co-toxicity coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜
Co-toxicity coefficient (CTC) ＜ 120 shows as summation action.Test result is shown in Table 1-4.
