The present invention relates to the Herbicidal combinations containing benzene flumetsulam and anilofos, the Herbicidal combinations have synergistic function, wherein, the mass ratio of benzene flumetsulam and anilofos is 0.1：0.1~20:100, further preferably 1：1~15:50, finally preferably 1：8~2:25.
Description
Technical field
The present invention relates to a kind of herbicidal compositions of farmland weed, and in particular to be a kind of benzene flumetsulam and
The ternary built herbicidal composition of anilofos and its application.
Background technology
In recent years, as the requirement of pesticide developing noval chemical compound is gradually increased, in accordance with highly selective, high security, height
It needs to save drug cost while drug effect medication policy, faced with this situation, we are by closing existing compound
Reason is used in compounding, so as to achieve the purpose that solve the problems, such as this.
Benzene flumetsulam, other titles：Ba Baijin, molecular formula are：C17H17ClF4N4O5S, chemical name：[2- is chloro- by N'-
The fluoro- 5- of 4- (- 1 (2H)-pyrimidine of 3- methyl -2,6- dioxies -4- (trifluoromethyl) -3,6- dihydros) benzoyl]-N- isopropyls-N-
Methyl sulphamide.Benzene flumetsulam is a kind of steriland herbicide, by the way that chlcrophyll biosynthesis is interfered to act on, can effectively be prevented and kill off
More than 70 kinds of weeds in 30 various crop such as corn, sorghum, soybean, cotton, fruit tree, including having to glyphosate and ALS inhibitor
The weeds of resistance, such as lamb's-quarters, Horseweed Herb, Russian Ji, long awns amaranth and artemisiifolia, to crop safety height, are praised by BASF AG
For " two develop most successful novel herbicide during the last ten years ".
Anilofos, other titles：Twilight rice Thailand, Ge Dajin, A Luojin, molecular formula are：C13H19ClNO3PS2Chemical name：
Chloro- N- cumenes carbamo, lmethyl-O, O-2- the dimethyl disulfide substituted phosphates of S-4-.Anilofos are a kind of organic phosphates
Selection type herbicide has uptake and translocation effect, and medicament is mainly absorbed by stem in the young shoot of plant and ground, inhibits cell division
With elongation.Anilofos are best to the weeds effect sprouted, and also have certain preventive effect to the weeds to have grown up.Weeds are after by medicine
It stops growing, blade is dark green, decolourizes sometimes, and blade shortens and thick, easily fractures, lobus cardiacus is not easy to extract out, and last whole plant is withered
Extremely.Anilofos can prevent and kill off annual gramineous weed and nutgrass flatsedge, such as barnyard grass, bald barnyard, rice barnyard grass, moleplant seed, cyperus iria, different
Type nutgrass flatsedge, dichotomous fimbristylis herb etc., but it is bad to other grassy weed preventive effects, such as lady's-grass, Bermuda grass.
Invention content
The invention belongs to herbicide fields, disclose the mixed herbicide of a kind of flumetsulam containing benzene and anilofos and its answer
With present invention aims at the limitations for solving single dose controlling object, under the premise of drug effect is improved, delay Weed Resistance, prolong
The service life of long each ingredient, herbicidal spectrum is wide, realizes that a drug can just solve nearly all weeds in farmland, saves medication
Cost simultaneously has certain safety to succession crop, provides a kind of cost-effective low toxicity, efficient herbicidal composition.
Further, in Herbicidal combinations of the invention active constituent be benzene flumetsulam and anilofos, they compound
Mass ratio is 0.1：0.1~20:100, further preferably 1：1~15:50, finally preferably 1：8~2:25.
The Herbicidal combinations of the present invention can be with auxiliary element conventional in Pesticide formulation according to customary preparation methods
Any one dosage form is prepared, such as can be missible oil, wettable powder, water dispersible granules, granule, suspending agent, solvable
Property liquor, dispersible oil-suspending agent, dry suspending agent etc..
The present invention Herbicidal combinations frequency of use and usage amount with crops, weeds, weather condition and it is small change,
It can achieve the purpose that effectively to prevent by using suitable dosage.
The Herbicidal combinations of the present invention may also include other agricultural active ingredients, such as the herbicide of other types, desinsection
In the agricultural actives such as agent, fungicide, fertilizer, plant growth regulator, biostimulant and safener ingredient and/or plant protection
Common additive and/or insecticides adjuvant can use together with which.
Compared with prior art, the present invention it has the following advantages that：1st, activity of weeding is high, and preventive effect is significantly higher than any one
A single dose；2nd, different role mechanism has complementary advantages, is synergistic, matching rationally；3rd, expand herbicide controlling spectrum, to annual and perennial
Grass family, broad-leaved and sedge weed have good preventive effect, can a dispenser solve whole weeds, and with closing down economic benefits and social benefits
Double action.

It is continuous stir evenly after add organobentonite, white carbon, citric acid and benzene flumetsulam, after high speed shear is uniform, into sleeping
It is ground in formula sand mill, makes material particular diameter all at 5 μm hereinafter, can be prepared by 21% benzene flumetsulam Sha of the present invention
The dispersible oil-suspending agent of barnyard grass phosphorus.
2nd, toxicity measures
Test method：Quantitative weed seed (barnyard grass, setose thistle, difformed galingale herb) is seeded in the plastics of diameter 9cm respectively
In alms bowl, per 15~20, basin seed, after planting 0.5~1cm of earthing or so, treats that weed seed is emerged, growing way reach 2 leaf, 1 heart with
Afterwards, weed growth vigorous period carries out cauline leaf spraying treatment.It is placed in greenhouse after processing, periodical visual inspection observes the weeds of each processing
Survival condition, and investigated at the 21st day, calculate the practical strain preventive effect of each processing.
Synergy evaluation method：
The synergy of herbicide is evaluated according to Gowing methods, formula is as follows：
X, Y is the weeds of each single dose with respect to strain preventive effect；
E0：Represent the theoretical preventive effect of each processing；
E：Represent the practical preventive effect of each processing；
Evaluation criterion：As E ＞ E0When, show as synergistic effect；Work as E=E0When, show as summation action；As E ＜ E0When,
Show as antagonism.
Result of the test：Can be seen that benzene flumetsulam and anilofos compounded combination by 1 indoor biometrics experiment result of table makes
With having good synergistic effect, and practical preventive effect can reach more than 80% to weeds.
1. benzene flumetsulam of table and anilofos integrate weeds the measurement result of virulence
3rd, bare place weeds field trial is prevented and kill off
Reagent agent：Embodiment 1, embodiment 2, embodiment 3, embodiment 4, embodiment 5, embodiment 6 totally 6 kinds of compounded combinations
Object.
Comparison medicament：Single dose benzene flumetsulam, anilofos and complex preparation.
Controlling object：The common weed that bare place occurs, barnyard grass, lamb's-quarters, setose thistle, Horseweed Herb, difformed galingale herb etc..
Application method：In weed growth vigorous period, uniformly it is watered cauline leaf spraying treatment.
Pilot survey：7 days range estimation weeds strain preventive effects after dispenser, 21 days actual measurement weeds strain preventive effects and fresh weight preventive effect after dispenser,
And use 5 point samplings, every 1m2It is sampled investigation.
The different reagent agents of table 2. are to the anti-division result of bare place weeds
Field test results：The benzene flumetsulam and anilofos complex preparation of different ratio are to bare place weed control efficacy
Significantly, hence it is evident that better than each single dose preventive effect, solved after two kinds of medicament mixtures bare place malignant weed barnyard grass, lamb's-quarters, setose thistle, it is small fly
The problem of fluffy, difformed galingale herb etc..
In conclusion instant component is reasonable, preventive effect is better than the effect that each component single dose is used alone, and the lasting period is long,
Times for spraying is reduced while expanding herbicide controlling spectrum, saves drug cost, it is good to crop safety, delay Weed Resistance after dispenser
Occur, meet efficient, safe, highly selective pesticides application policy.
