Description
Technical field
The invention belongs to agrochemicals field, problem is prevented and kill off for rice terrace annual grassy weeds is solved more particularly, to one kind
The Herbicidal combinations containing benzobicylon, pretilachlor and penoxsuam.
Background technology
Benzobicylon (benzobicylon) belongs to double-octane class herbicide, and the mechanism of action is para hydroxybenzene benzylacetone
Acid esters dual oxide enzyme inhibitor.The compound can effectively prevent and kill off barnyard grass, Monochoria vaginalis, Procumbent Falsepimpernel, arrowhead, rain to rice safety
The rice terrace malignant weeds such as long flower, flat stalk Fischer grass.
Pretilachlor (pretilachlor) belongs to chloroacetanilide herbicides, is mainly suppressed by hindering protein to synthesize
The growth of cell.Medicament can be absorbed by plant hypocotyl, mesocotyl and plumule, and root slightly has absorption, and damage symptoms are
Acrospire is not unearthed or is stretched out from bud scale side, and distortion is unable to normal extension, stopping of growing, until dead.To barnyard grass, horse
The annual gramineous weeds such as Tang, moleplant seed have good sealing process, and remove part annual broadleaf weed and Cyperaceae
Weeds.
Penoxsuam (penoxulam) belongs to triazolopyrimidine sulfonamides herbicide, and the mechanism of action is acetolactic acid
Synzyme (ALS) inhibitor, can be conducted to separate living tissue, suppression through cauline leaf, young shoot and Root Absorption by xylem and bast
Plant strain growth processed, makes plant necrosis, dead.Direct-sowing dry field, direct-sowing rice, rice seedling bed and seedling throwing field, rice transplanting suitable for paddy rice
Cultivation field.Insecticide-applying way can use spraying or mix native treatment.Penoxsuam is rice field broad-spectrum herbicide, can effectively prevent and kill off barnyard grass
Grass, moleplant seed and annual sedge weed, and it is effective to numerous broad leaved weeds.
There is different degrees of defect in the herbicide kind containing single-activity component, on control of weeds such as after continuous use
Weeds easily develop immunity to drugs, and herbicide controlling spectrum narrows, the problems such as cause environmental pollution.
Rationally compounding is to improve preventive effect, expand herbicide controlling spectrum, widen use time to herbicide, delays shift of weed community
Speed, reduce that agricultural chemicals is single to use brought resistance risk, mitigate the pollution to environment, reduce use cost and mitigation removed
A kind of effective ways of careless agent residual.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of poison more high and low to crop safety, low-residual, kill
Grass spectrum is wide, can effectively delay the Herbicidal combinations containing benzobicylon, pretilachlor and penoxsuam of herbicide resistance.
The technical solution adopted for the present invention to solve the technical problems is：One kind contains benzobicylon, pretilachlor and five fluorine
The Herbicidal combinations of sulphur grass amine, including following active principle：Benzobicylon, pretilachlor and penoxsuam, described is bicyclic
Sulphur humulone, pretilachlor and penoxsuam weight ratio are (1~30):(1~30)：1.
Further, the preferred weight ratio of the benzobicylon, pretilachlor and penoxsuam is (5~15):(5~
20)：1.
Further, the weight of the benzobicylon, pretilachlor and penoxsuam account for composition total weight 1~
80%.
Further, described Herbicidal combinations formulation is granule, wettable powder, dispersibles oil-suspending agent.
Further, described Herbicidal combinations formulation auxiliary element is carrier, adhesive, surfactant etc..
Further, described Herbicidal combinations can be used for preventing and kill off rice terrace annual grassy weeds.
The frequency of use and usage amount of Herbicidal combinations of the invention with plant growth, weeds occur, Changes in weather and
There is a small amount of change, the purpose of effective preventing and treating can be reached by using appropriate dosage.
The agricultural chemicals such as surfactant used and carrier auxiliary element belongs to environmentally friendly type in Herbicidal combinations of the invention, low
Poison, low-residual, to rice safety, will not produce murder by poisoning to crop, fishes and shrimps and water body in use.
In sum, the beneficial effects of the invention are as follows, using convenient, low cost, reduce usage amount, reduce times for spraying,
Broad weed-killing spectrum, can effectively delay herbicide resistance to produce, and herbicidal effect is very remarkable.
Specific embodiment
In order that those skilled in the art are better understood from the present invention program, below by the technology in inventive embodiments
Scheme carries out clear, complete description.
Active ingredient uses 98% benzobicylon active compound, 95% pretilachlor active compound active compound, 95% in following examples
Penoxsuam active compound and auxiliary element are commercially available.
Indoor biometricses are tested
Prevent and kill off paddy field weed indoor pharmacodynamic test：
Illustrate that benzobicylon, pretilachlor and penoxsuam mixture are miscellaneous to rice terrace below by Toxicity Determination
Careless prevents and kill off with synergistic function.
In order to prevent and kill off paddy field weed, inventor is with active component as benzobicylon, pretilachlor and penoxsuam are entered
The synergy research of mutual compounding is gone, specific method is：Experiment target is designated as flat stalk Fischer grass (Scirpus planiculmis
Fr.Schmidt).The test medicine that active compound is configured to need, test method reference《People's Republic of China's agricultural industry mark
The quasi- part of NY/T1155.7-2006 farm-chemical indoor determinations test rule herbicide the 7th：The synergy of mixture is determined》.It is first
Single dose and each Mixed Pharmacy are first arranged to 5-7 various concentrations.If clear water is compareed, it is repeated 4 times.Using soil spray-on process, carry
Before get ready for examination target, after target is broadcast to be unearthed before medication, the medicament that will have been diluted spray tower (Ministry of Agriculture's Nanjing agriculture machine
Xie Hua research institutes, 3WPSH-500D, atomisation pressure 3.0kg/cm3) be uniformly sprayed onto on target, insert in greenhouse and normally cultivate,
The preventive effect that 21 days calculate each chemicals treatment with ocular estimate after treatment, by between the probit value of preventive effect and the logarithm value of series concentration
Linear regression analysis, obtain the ED of each medicament50Value, the co-toxicity coefficient (CTC) of mixture, co-toxicity coefficient are calculated with the abundant methods of Sun Yun
(CTC) synergistic effect is shown as more than or equal to 120；CTC shows as antagonism less than or equal to 80；More than 80 and less than 120 tables
It is now summation action.
The combination of the benzobicylon of table 1, pretilachlor and penoxsuam is to flat stalk Fischer grass (Scirpus planiculmis
Fr.Schmidt Toxicity Determination)
Toxicity Determination result shows：The weight ratio of benzobicylon, pretilachlor and penoxsuam is (5~15)：
