Description

Synergistic herbicide compositions
Technical field
The invention belongs to Synergistic herbicide compositions fields, and in particular to one kind contains active constituent chlorine fluorine pyridine ester, cyanogen fluorine The Synergistic herbicide compositions of careless ester, pretilachlor.
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. are respectively provided with activity of weeding, and rice is pacified Entirely.
Cyhalofop-butyl belongs to aryloxyphenoxypropionic class herbicide, can be absorbed by the blade of plant and leaf sheath, bast Conduction accumulates the meristem zone in plant, resists acetyl-CoA carboxylase (ACCase), stops aliphatic acid synthesis, carefully The growth division of born of the same parents cannot be normally carried out, and the structure containing fat such as membranous system is destroyed, and is finally resulted in Plant death rice terrace and is selectively removed Careless agent can only make cauline leaf process, and bud pre-treatment is invalid, mainly prevents and kill off the grassy weeds such as barnyard grass, moleplant seed.
Pretilachlor, acetamide-group herbicides selectively sprout pretreating reagent, can pass through plant hypocotyl, mesocotyl and plumule It absorbs, root slightly absorbs, the synthesis of direct interference weeds vivo protein, and has indirect influence to photosynthetic and respiration.By The seedling distortion of evil weeds, acrospire difficulty are stretched out, and leaf color turns dark green, and growth stops, until dead.Rice has pretilachlor stronger Capacity of decomposition, so as to certain selectivity.
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 no 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 one of maximally efficient and economic method to solve the above problems to select 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, cyhalofop-butyl, pretilachlor, three's mechanism of action is different, and herbicide controlling spectrum is not quite similar, and single dose uses appearance Drug resistance is also easy to produce, dosage is increasing, and herbicide controlling spectrum is relatively narrow, it is impossible to meet real needs.
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 constituent chlorine fluorine pyridine ester, cyhalofop-butyl, the third grass The mass fraction ratio of amine is 0.5~5:10:There is synergistic effect to target weeds in the range of 2~20.
Further preferred chlorine fluorine pyridine ester, cyhalofop-butyl, pretilachlor mass fraction ratio be 0.5~3:10:2~20.
Further preferred chlorine fluorine pyridine ester, cyhalofop-butyl, pretilachlor mass fraction ratio be 0.5~3:10:5~10.
Further preferred chlorine fluorine pyridine ester, cyhalofop-butyl, pretilachlor mass fraction ratio be 0.5:10:5、0.5:10: 10、1:10:10、1:10:10。
The Synergistic herbicide compositions active constituent accounts for the 5%~95% of composition quality percentage composition, remaining is pesticide Auxiliary agent.
The Synergistic mixture of the present invention can be administered in combination to prevent more extensive farming class with one or more of other herbicides Undesirable vegetation.When being used in combination with other herbicides, the composition can match with other one or more herbicides System is mixed with other one or more herbicides progress tanks or is successively applied with other
