Abstract
The invention discloses a kind of Herbicidal combinations containing clefoxidim and penoxsuam and its application, it is clefoxidim and penoxsuam that effective active, which becomes A, and B is one kind of metamifop or cyhalofop-butyl.Active components A and the proportion of B are 1:50~50:1.Active constituent gross mass accounts for the 5%~80% of the quality of the pharmaceutical preparations, preferably 20%~60%.Combination dosage form is the dosage form that the pesticidal preparations such as dispersible oil-suspending agent, suspending agent, granule, missible oil, wettable powder, water dispersible granules, suspoemulsion, aqueous emulsion, microcapsule suspending agent allow.Herbicidal combinations can be used for preventing and kill off paddy field weed.
Description
Technical field
The present invention relates to technical field of pesticide, specifically, being related to a kind of removing containing clefoxidim and penoxsuam
Careless composition.
Background technique
Rice is one of China's staple food crop, about 33,000,000 hectares of cultivated area, accounts for about plant of grain crops area
29%.South Rice Region of China and north paddyfield can be divided into according to the characteristics of geographical location and Rice Production.Paddy field it is important miscellaneous
Grass is barnyard grass, firefly Lin, needle spikesedge herb, Monochoria vaginalis, mexicana, ambatch, toothcup, Procumbent Falsepimpernel class, wild arrowhead, water chestnut etc., is
One of the principal element for influencing yield and quality of rice is such as not added to prevent and treat, will cause a large amount of underproduction of rice, underproduction amplitude can
Up to 40% or so.
Currently, preventing and kill off the main weeding pesticide species of weeds in field for paddy field there are safeties and is (outstanding by environmental condition
It is temperature and humidity condition) it is affected, drift strong disadvantage；And the long-term single use of weeding pesticide leads to a variety of weeds in field
Drug resistance rapid development, if increasing usage amount, to will lead to rice seedling phytotoxicity risk big；Secondly existing weeding Pesticide use is at high cost, miscellaneous
Grass is easy to recur.With the increase of the agent for removing grass in paddy field Pesticide use time limit, rice field is difficult to the Weed species and quality day prevented and kill off
Benefit increases.Therefore, there is an urgent need to develop a kind of efficient, low toxicity, low-residual, safety new type water paddy field weeding pesticide.
Clefoxidim is cyclohexanone oxime herbicide, belongs to fatty acid sythetase inhibitor, can inhibit acetyl-coa carboxylase
Enzyme.It is selective to rice, it is due to degrading quickly on rice, so that the amount for being transported to site of action is reduced.In plant
It is inside transmitted to separate living tissue, weeds stop growing, and leaf turns yellow or reddens.Can be used for rice field prevent and kill off gramineae weed such as barnyard grass,
Lan Macao, herba digitariae, herba eleusines indicae, semen euphorbiae, herba setariae viridis grass, dayflower, simple axis thatch etc..
Penoxsuam is triazolo pyrimidine class herbicide, belongs to branched-chain amino acid synthetic inhibitor.Selectivity is based on difference
Metabolic transformation be inactive metabolin.Mainly by blade absorption, secondly by more absorbing, and in bast and xylem
Conduction.Symptom includes the growth inhibition almost to get instant result, and a sallow growth point with terminal bud necrosis causes plant to exist
It is dead in 2-4 weeks.It is used before bud, after bud with the water phase.It can be used for preventing and kill off the aquatic weed of rice field Echinochloa and many broad-leaved Cyperaceaes.
Penoxsuam can provide weed control according to soil types type and dosage, be drenched with rain using the resistance to rain of rear 1h.It is mainly used for
Dry sowing, water are broadcast and weeding after transplanting rice field bud.
Metamifop, cyhalofop-butyl are fragrant phenoxy phenoxy propionic acid inner-adsorption conduction-type herbicide.It can inhibit acetyl coenzyme A
Carboxylase causes the biosynthesis block of vegetable fatty acid, keeps cell division stopping, cell membrane destructurized containing rouge, causes
Weeds are dead, reach herbicidal effect.It can be used for paddy field cauline leaf process and prevent and kill off a variety of gramineae weeds such as barnyard grass, semen euphorbiae.
In practical agricultural production process, the above medicament is used alone, it is relatively narrow that there are herbicidal spectrums, and dosage is big, increases into
This, aggravated environmental pollution, in addition single dose quick-acting or lasting effect it is also poor, continuous use after weeds be easy to produce drug resistance etc.
A series of disadvantages.Good in order to develop quick-acting and lasting effect, the lower new pesticide combination of use cost, we are indoors
It is raw to survey on the basis of screening and field trial, clefoxidim, penoxsuam and oxazole acyl grass have been filtered out by a large number of experiments
The herbicide for paddy field of amine or cyhalofop-butyl mixture.The composition has apparent synergistic effect, high-efficiency environment friendly.
Related clefoxidim patent is through inquiring by the agent for removing grass in paddy field being made of clefoxidim and clomazone so far
Composition (application number: 201710061016.7 applyings date: 2017-01-25), a kind of rice comprising clefoxidim and azoles humulone
Field weeding composition (application number: 201710060972.3 applyings date: 2017-01-25), a kind of herbicide group containing clefoxidim
Close object (application number: 201410658594.5 applyings date: 2014-11-18), a kind of answering containing clefoxidim and penoxsuam
With patents such as compositions (application number: 201110006516.3 applyings date: 2011-01-13), but there has been no about clefoxidim,
The patent disclosure of penoxsuam and metamifop or cyhalofop-butyl mixture.
Up to now simultaneously, it does not inquire in pertinent literature or report about clefoxidim, penoxsuam and evil
The relevant report that azole amide or cyhalofop-butyl are used in combination.
