Abstract
The present invention relates to the Herbicidal combinations containing anilofos, cyhalofop-butyl and benzobicylon, the Herbicidal combinations have synergistic function, wherein, active constituent is anilofos, cyhalofop-butyl and benzobicylon in Herbicidal combinations of the invention, the mass ratio that they are compounded is 1~50:1~30:5~25, further preferably 1~25:5~30:5~25, most preferably 10~25:5~30:5~20.
Description
Technical field
The invention belongs to pesticide herbicides to compound field, and in particular to be a kind of miscellaneous for preventing and kill off grass family in paddy field
Grass, broadleaf weeds and the herbicidal composition of nutgrass flatsedge, are by three kinds of anilofos, cyhalofop-butyl and benzobicylon active constituents
The ternary built herbicidal composition of composition.
Background technique
Anilofos English common name Anilofos, other Chineses have twilight rice Thailand, Ge Dajin, A Luojin, chemical name
Claim: chloro- N- cumene carbamo, lmethyl-O, O-2- the dimethyl disulfide substituted phosphate of S-4-.
Anilofos are a kind of organic phosphates herbicides, are a kind of Uptake and translocation selection type herbicides, and medicament mainly passes through plant
Stem absorbs in the young shoot and ground of object, inhibits cell division and elongation.Anilofos are best to the weeds effect sprouted, to
The weeds to grow up also have certain preventive effect.Weeds stop growing after by medicine, and blade is dark green, decolourize sometimes, and blade shortens and thick, easily
It fractures, lobus cardiacus is not easy to extract out, and last whole plant is withered.
Anilofos can prevent and kill off annual gramineous weed and nutgrass flatsedge, and such as barnyard grass, bald barnyard, rice barnyard grass, semen euphorbiae, crack rice Sha
Grass, difformed galingale herb, dichotomous fimbristylis herb etc..
Cyhalofop-butyl, it is uptake and translocation herbicide, is absorbed by the blade and leaf sheath of plant, bast conduction, product
Tire out the separate living tissue in plant, inhibit acetyl-CoA carboxylase, stop fatty acid synthesis, the growth division of cell cannot
It is normally carried out, finally results in Plant death.Weeds damage symptoms are 5-7 days, weeds since the lobus cardiacus yellow, browning, then by
Flaring dissipates and complete stool, and the death time about 2-3 weeks.The main controlling object of cyhalofop-butyl is barnyard grass, semen euphorbiae, herba digitariae, double fringe sparrows
The gramineae weeds such as barnyard grass, herba setariae viridis, herba eleusines indicae, it is invalid to broadleaf weeds and nutgrass flatsedge.
Benzobicylon (benzobicyclon), chemical name: 3- (the chloro- 4- methylsulphonyl benzoyl of 2-) -2- benzene
Bicyclic [3.2.1] oct-2-ene -4- ketone of sulfenyl.Benzobicylon is bicyclic pungent by one kind of Japanese SDS biotech company research and development
Alkane chemical herbicide synthesizes for 1992, and progress field trial in 1994, desk study terminates within 1998, for preventing and kill off paddy field
Annual and perennial weeds.
Benzobicylon is p _ Hydroxyphenyl pyruvic acid dual oxide enzyme inhibitor (HPPD), it influences matter by inhibiting HPPD
The synthesis of body quinone, then phytoene dehydrogenase (PDS) is acted on by plastoquinone, to finally influence the life of carotenoid
Object synthesis, makes blade albefaction.
Benzobicylon is a kind of for preventing and kill off the wide spectrum selective herbicide of weeds in rice direct seeding field and transplant field.It is logical
The root and basal part of stem for crossing weeds absorb, to be transmitted to entire plant.Mainly prevent and kill off Herba Setariae palmifoliae, Cyperus, barnyard grass, fake rice, thousand
Gold, Monochoria vaginalis, bog pondweed and firefly Lin etc. be annual and perennial weeds.
Benzobicylon has bicyclic and phenyl sulfide structure, there is very strong adsorption by soil, is studied by metabolism, and confirmation is double
The metabolite of ring sulphur humulone has the function of high inhibition HPPD, therefore it is as precursor herbicide, early stage before bud or after bud
Application, lasting period are long.Benzobicylon belongs to non-inhibited branched-amino acid enzyme --- acetolactate synthestase (ALS) effect
Mode is up to firefly Lin and the weeds lasting period for generating resistance to sulfonylurea herbicide 50 days.
In recent years, rice field weeds are more serious, practice discovery through field investigation in a few years, field malignant weed is excellent
Gesture is more and more obvious, such as barnyard grass, rice barnyard grass, rhizoma alismatis, Monochoria vaginalis, arrowhead, firefly Lin, and anilofos are used alone and are prevented and kill off, only
Annual gramineous weed and part nutgrass flatsedge can be prevented and kill off, it is invalid to broadleaf weeds, while dosage is excessively high has certain wound to rice
Evil, phytotoxicity risk are larger.And cyhalofop-butyl is used alone, and it is merely able to prevent and kill off part annual gramineous weed, it is serious to occurring
Resistant weed it is nearly unavailable.Therefore be badly in need of develop a kind of highly effective and safe, can disposably be administered can prevent and kill off field it is pernicious and
The herbicide of resistant weed.
Summary of the invention
Present invention aims at solve the limitation of single dose controlling object in agent for removing grass in paddy field technology, delay Weed Resistance
Occur, improve the safety improved while weed control to crop, realizes that a drug is just able to solve Tanaka one season weeds,
The herbicidal composition that one kind is efficient, less toxic, at low cost, easy to use, quick-acting is good, and the lasting period is grown is provided.
Passing through a large amount of field trial, in order to overcome existing anilofos and the undesirable defect of cyhalofop-butyl preventive effect,
The present invention on the basis of existing technology, especially compounds a kind of new herbicides --- and benzobicylon, benzobicylon is to firefly
Lin and the weeds effect for generating resistance to sulfonylurea herbicide are good, and being used in compounding with cyhalofop-butyl, anilofos can make up not
Foot, different role mechanism coordinates synergy, to achieve the purpose that prevent and kill off resistant weed, while guaranteeing the safety of crop, three again
Compounding also helps the generation for alleviating Weed Resistance.Therefore the invention reside in researched and developed a kind of Herbicidal combinations can protect
It demonstrate,proves a drug and solves the common malignant weed of rice field and partial resistance weeds.
The present invention provides a kind of herbicidal compositions, including active constituent: anilofos, cyhalofop-butyl and bicyclic sulphur grass
Ketone.By comparing each single dose and two-spot compounding, the combinations of herbicides of the best preventive effect of ternary built is screened.
Further, in Herbicidal combinations of the invention active constituent be anilofos, cyhalofop-butyl and benzobicylon, it
The mass ratio that compounds be 1~50:1~30:5~25, further preferably 1~25:5~30:5~25, most preferably 10~
25:5~30:5~20.
Further, Herbicidal combinations of the invention can be used for preventing and kill off gramineae weed in paddy field, broadleaf weeds
And sedge weed.
The frequency of use and usage amount of Herbicidal combinations of the invention with crops, weeds, weather condition and it is small change,
It can achieve the purpose that effectively prevent by using suitable dosage.
Herbicidal combinations of the invention may also include other agricultural active ingredients, such as herbicide, the desinsection of other types
Common additive and/or insecticides adjuvant in agent, fungicide, the pesticide activity component of fertilizer and safener and/or plant protection,
Or it can use together with which.
Herbicidal combinations of the invention can be with auxiliary element conventional in Pesticide formulation according to customary preparation methods
Any one dosage form is prepared, for example, can be missible oil, water dispersible granules, granule, suspending agent, dispersible oil-suspending agent,
Dry suspending agent etc..
Compared with prior art, Herbicidal combinations of the invention have the beneficial effect that instant component is reasonable, after compounding
Preventive effect is better than the effect that each component is used alone, and there is synergistic function can effectively be slowed down miscellaneous by the different mechanism of action
The generation of careless resistance, it is good to Security of rice, meet the security requirement of pesticidal preparations.
