Description

Synergistic herbicide compositions
Technical field
The invention belongs to Synergistic herbicide compositions fields, and in particular to a kind of Herbicidal synergistic containing active components A, B, C Composition；Wherein A is selected from chlorine fluorine pyridine ester, and B is selected from pyraclonil, and C is selected from piperazine pyrazosulfuron, halosulfuronmethyl, the phonetic sulphur of promazine One kind grand, in orthosulfamuron.
Background technology
Chlorine fluorine pyridine ester belongs to growth regulator class herbicide member, to grassy weed such as barnyard grass, moleplant seed, Cyperaceae Weeds such as cyperus iria, dichotomous fimbristylis herb etc., broad leaved weed such as rhizoma alismatis, arrowhead, Monochoria korsakowii etc. all have activity of weeding, pacify to rice Entirely.
Pyraclonil (pyraclonil), belongs to novel double pyrazole class herbicide for paddy field, and the mechanism of action is protoporphyrinogen The inhibitor of oxidizing ferment is a kind of contact killing type herbicide.Can effectively prevent and kill off all kinds of weeds, including barnyard grass, difformed galingale herb, water plant, Arrowhead, Monochoria korsakowii, dichotomous fimbristylis herb, wild water chestnut, Monochoria vaginalis etc. and the weeds resistant to sulfonylurea herbicide.
Piperazine pyrazosulfuron (metazosulfuron), Nissan Chemical develop herbicide, are mainly used for preventing and kill off wheat paddock, rice Field annual broadleaf weed and part grassy weed such as lady's-grass, barnyard grass etc., to broad-leaveds such as piemarker, Amaranthus retroflexus, short arrowhead, field thistles Weeds have preferable preventive effect.
Promazine Sulfometuron Methyl (Propyrisulfuron) is a kind of selected from property broad-spectrum herbicide, has residual effect effect, to resistance to The weeds of sulfonylurea herbicide have preferable preventive effect, it is effective to above the average age for marriage barnyard grass, nutgrass flatsedge, broadleaved herb, can foliar spray, It gets rid of and applies.
Halosulfuronmethyl is rice field wide spectrum being selected from property inner-adsorption conduction-type herbicide, is mainly absorbed by root system, also may be used It is absorbed by cauline leaf, is shifted rapidly in weeds plant body, inhibit growth, weeds are gradually dead, can prevent and kill off annual broad-leaved Weeds and sedge weed.
Bensulfuron-methyl is rice field wide spectrum being selected from property inner-adsorption conduction-type herbicide, is mainly absorbed by root system, can also be led to Cauline leaf absorption is crossed, is shifted rapidly in weeds plant body, inhibits growth, weeds are gradually dead, and it is miscellaneous can to prevent and kill off annual broad-leaved Grass and sedge weed.
Pyrazosulfuron is rice field wide spectrum being selected from property inner-adsorption conduction-type herbicide, is mainly absorbed by root system, can also be led to Cauline leaf absorption is crossed, is shifted rapidly in weeds plant body, inhibits growth, weeds are gradually dead, and it is miscellaneous can to prevent and kill off annual broad-leaved Grass and sedge weed.
Ethoxysulfuron is a kind of safe and efficient herbicide for paddy field, can be used for rice direct seeding field and rice transplanting field.It is acted on Mechanism is transmitted in plant after being absorbed by weeds root and cauline leaf, prevents Amino acid synthesis, and inhibit weeds cauline leaf rapidly Growth and root elongation, it is completely withered to finally result in weeds.
Cinosulfuron is by hindering valine and isoleucine to synthesize, to inhibit growing up for cell division and cell.Medication Lacking practice and skill long stopping, 5~10d plant start yellow, withered, death.It can be used for rice transplanting rice, Direct-seeding Rice and rice seedling bed, prevent and kill off annual Broad leaved weed and sedge weed.
Flucetosulfuron is a kind of sulfonylurea herbicide developed by LG Corp of South Korea life science Co., Ltd, can For transplanting and direct seading rice field；Barnyard grass, broad-leaved and sedge weed can be effectively prevented and kill off for soil or cauline leaf process；Greenhouse and Field trial shows, for rice terrace to rice safety, on succession crop without influence.
Cypromisulfuron be sulfonylurea rice field wide spectrum be selected from property inner-adsorption conduction-type herbicide, sulfonylurea herbicide, Inhibitor of acetolactate synthetase, can effectively prevent and kill off sedge weed and broad leaved weed, have at high doses to barnyard grass stronger Inhibiting effect.
Farmland weed grass is mutually complicated, and type is various, is to prevent and kill off the most effective chemical means of agricultural weed using chemical agent One of；With the novel pesticide of not cross resistance come to prevent and kill off agricultural weed be a good solution；But one is developed at present A novel pesticide needs to screen a compounds up to ten thousand, and hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, it is difficult to which that catches up with is upper miscellaneous The speed that grass develops immunity to drugs；Other methods such as crop structure adjustment, different pesticide rotations etc., in actual mechanical process, It is difficult to play apparent effect.
Rational chemical herbicide compounding or mixture, which have, expands herbicide controlling spectrum, improves control effect, extends dispenser period, subtracts Few dosage reduces poisoning risk, reduces residual, delays the advantages that generation and development of weeds drug resistance and drug resistance, so It is maximally efficient and economic one of the method to solve the above problems selected from suitable mixture of herbicides or mixture；However because agriculture The mechanism of action is complicated between medicine mixture, and whether synergy is affected by various factors after combination, only relies on experimental result and is subject to Verification, can not be expected.
Develop new product herbicide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
Chlorine fluorine pyridine ester, pyraclonil, promazine Sulfometuron Methyl；Chlorine fluorine pyridine ester, pyraclonil, piperazine pyrazosulfuron；Chlorine fluorine pyrrole Pyridine ester, pyraclonil, halosulfuronmethyl；Chlorine fluorine pyridine ester, pyraclonil, orthosulfamuron combination have not been reported.
Invention content
The present invention is intended to provide a kind of ternary Synergistic herbicide compositions, solution is provided for Weed Resistance management, it is agriculture Medicine decrement reduces farmland weed processing cost using solution is provided.
The technical scheme is that：Synergy grass composition, contains active components A, B, C；Wherein A is selected from chlorine fluorine pyridine Ester, B be selected from pyraclonil, the one kind of C in piperazine pyrazosulfuron, halosulfuronmethyl, promazine Sulfometuron Methyl, orthosulfamuron, A, B, the mass fraction ratio of C is 0.5~4:10:0.5~8.
The mass fraction ratio of further preferred A, B, C are 0.5~2:10:0.5~6.
The mass fraction ratio of further preferred A, B, C are 1~2:10:1~6.
