Description

A kind of Synergistic herbicide compositions containing propanil
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 selects propanil, and B is selected from cyhalofop-butyl, and C is selected from dichloro quinolinic acid.
Background technique
Propanil is the highly selective contact killing type herbicide of amides, not only breaks up the photosynthesis of plant, but also is inhibited Respiration and the phosphorylation of oxygen public affairs, interfering nucleic acid are synthesized with protein.To make the physiological function of sensitive plant by It influences, accelerates dehydration, blade gradually dried-up, it is last dead.
Cyhalofop-butyl (cyhalofop-buty), be in fragrant phenoxy phenoxy propionic acid herbicide it is only to rice have height pacify The kind of full property is as such other kind and uptake and translocation herbicide.It is absorbed by the blade and leaf sheath of plant, Bast conduction, accumulation resist acetyl-CoA carboxylase (ACCase) in the meristem zone of plant, synthesize fatty acid Stop, the growth division of cell cannot proceed normally, and the structure containing rouge such as membranous system is destroyed, and Plant death is finally resulted in.From cyanogen fluorine Careless ester is absorbed into that weeds death is slower, generally requires 1-3 weeks, the symptom of weeds after administration is as follows: four leaf stage it is tender Bud atrophy, leads to death.The old leaf of two leaf stage changes very little, and keeps green；It is mainly used for preventing and kill off important gramineae weed, cyanogen Fluorine grass ester is efficient to semen euphorbiae, there is certain preventive effect to low age barnyard grass, can also prevent and kill off, herba digitariae, Paspalum distichum, herba setariae viridis, Cowhells Grass, amur foxtail etc., it is invalid to sedge weed and broadleaf weeds.
Dichloro quinolinic acid (fenoxaprop-P-ethyl) belongs to heterocyclic oxy group phenoxy propionic acid class herbicide, mainly logical One acetyl-CoA carboxylase of key enzyme for inhibiting fatty acid synthesis is crossed, to inhibit the synthesis of fatty acid.Medicament passes through cauline leaf Assimilation and conductivity to separate living tissue and the growing point of root, effect rapidly, stops growing for 2-3 days after application, 5-6 days lobus cardiacus chlorosis purplings Color, separate living tissue browning color, blade is gradually withered, is the extremely strong cauline leaf process agent of selectivity.
Acetochlor is amides selectivity bud pre-treatment herbicide, mainly passes through monocotyledonous plumule or dicotyledonous The hypocotyl of plant absorbs, and conducts upwards after absorption, main by hindering protein synthesis that cell is inhibited to grow, and keeps weeds young Bud, young root growth stop, and then dead.The ability that gramineae weed absorbs Acetochlor is stronger than broadleaf weeds, so preventing and kill off grass The effect of section weeds is better than broadleaf weeds.45 days or so the lasting period of Acetochlor in the soil mainly passed through microbial degradation, Mobility in soil is small, is primarily retained in 0-3 cm layer of soil.
Grass phase is complicated for farmland weed, many kinds of, and application chemical agent is to prevent and kill off the most effective chemical means of agricultural weed One of；It is a good solution that agricultural weed is prevented and kill off with the novel pesticide of not cross resistance；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, is difficult to catch up with upper miscellaneous The speed that grass develops drug resistance；Other methods such as crop structure adjustment, different pesticide rotations etc., in the actual operation process, It is difficult to play apparent effect.
Reasonable chemical herbicide compounding or mixture, which have, expands degrass spectrum, improves control efficiency, extends application period, subtracts Few dosage reduces phytotoxicity 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, and only dependence experimental result is subject to Verifying, can not be expected.
Exploitation 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.
The combination of propanil, cyhalofop-butyl, dichloro quinolinic acid has not been reported.
Summary of the invention
The present invention is intended to provide a kind of ternary Synergistic herbicide compositions, provide solution for Weed Resistance management, it is agriculture Medicine decrement reduces farmland weed processing cost using solution is provided.
The technical scheme is that a kind of Synergistic herbicide compositions containing propanil, contain active components A, B, C；Its Middle A is selected from propanil, and B is selected from cyhalofop-butyl, and C is selected from dichloro quinolinic acid, the mass fraction ratio of A, B, C be 15~45:15:3~ 30。
The mass fraction ratio of further preferred A, B, C are 15~30:15:3~15.
