Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of Herbicidal mixture containing dichloro quinolinic acid, propanil and cyhalofop-butyl
Agent and its application.
Background technology
Dichloro quinolinic acid is a kind of quinoline carboxylic acid hormone-type selective herbicide, is the paddy field of BASF Corp. of Germany's exploitation
Herbicide starts the large-scale popularization use in paddy field weeding the nineties in last century in China.By the work for interfering enzyme in plant
Property, the biosynthesis of ethylene can be promoted, lead to the accumulation of a large amount of abscisic acids, plant growth is made to slow down, seriously then cause plant dead
It dies.It can promote plant growth in low concentration, when high concentration destroys plant hormone balance, keeps plant metabolism disorderly, influences light
Cooperation is used, respiration.Dichloro quinolinic acid is mainly used for preventing the monocotyledon weeds such as barnyard grass.
Propanil is a kind of contact killing type herbicide of tool high selectivity.There is very strong work of tagging to barnyard grass to rice seedling safety
With.The effect of propanil is to destroy the photosynthesis of plant, inhibits respiration and oxidative phosphorylation, interfering nucleic acid and albumen
Matter synthesis etc., makes the physiological function of aggrieved plant be affected, and dehydration, blade is accelerated gradually to dry up, last dead.Propanil is main
Barnyard grass, needle spikesedge herb are prevented and kill off for rice seedling bed, live streaming field and Honda.Can also be used for dry land prevent and kill off lady's-grass, green bristlegrass, Monochoria vaginalis,
The weeds seedling such as amaranth, amur foxtail.But it is substantially invalid to four leaf duckweed, bog pondweed, wild water chestnut etc., herbicidal spectrum is single, to weeds
Control has limitation
Cyhalofop-butyl is a kind of fragrant phenoxy phenoxy propionic acid selectivity inner sucting conduction type cauline leaf process herbicide.At cauline leaf
Reason can be that stem, the leaf of plant absorb, be transmitted to growing point and separate living tissue, be pressed down by the inhibition to acetyl-CoA carboxylase
The aliphatic acid of weeds processed synthesizes, and inhibits weed growth, is stopped growing in several days by medicine weeds, later gradually withered.The medicine is in water
In rice body, it can be degraded to two inactive acid-state rapidly, and it is highly safe to rice.It can be used for the rice of various planting patterns
Field has the dispenser phase wide, to succession crop safety, can effectively prevent and kill off the standing grain such as barnyard grass, moleplant seed, amur foxtail, Paspalum distichum, lady's-grass
Undergraduate course weeds
Herbicide for paddy field is limited by crop safety at present, and herbicide controlling spectrum is also limited, and a kind of herbicide single dose is used alone
Cannot completely effectively control the generation of paddy field weed, furthermore some herbicides due to the water-soluble big or field lasting period too
It grows, dosage is excessive or the uneven residual hazard all be easy to causeing to this season crop or succession crop of dispenser.Between herbicide
Compounding can solve the problems, such as that pesticide single dose toxicity is big, effect is poor and the R＆D cycle is short, and between different pesticides
Be used interchangeably the generation for capableing of retarding action object drug resistance, there is ideal using effect, therefore different role mechanism
Between the compounding of pesticide be current research focus in the field of pesticide.Dichloro quinolinic acid, propanil and cyanogen fluorine be not careless in the prior art
The relevant report of ester compounding.
Invention content
The purpose of the present invention is to provide a kind of component is reasonable, drug cost is low, is not likely to produce the herbicide group of drug resistance
Object is closed, it is miscellaneous to rice terrace grass family that there is preferable control effect, to slow down Weed Resistance, reduce drug dosage etc.
With positive effect.
The present invention provides following technical scheme
A kind of mixed herbicide containing dichloro quinolinic acid, propanil and cyhalofop-butyl, active constituent is by dichloro quinolinic acid, propanil
It is formed with cyhalofop-butyl, the weight ratio of the dichloro quinolinic acid, propanil and cyhalofop-butyl is 1-60:10-90:1-30.
The weight ratio of mixed herbicide of the present invention, the dichloro quinolinic acid, propanil and cyhalofop-butyl is 5-20:
15-60:1-8.The weight ratio of the preferred dichloro quinolinic acid, propanil and cyhalofop-butyl is 5:15:2.
The gross weight of dichloro quinolinic acid, propanil and cyhalofop-butyl in the composition described in mixed herbicide of the present invention
Amount percentage composition is 1-85%.The preferred total weight percentage of the dichloro quinolinic acid, propanil and cyhalofop-butyl in the composition
Content is 25-70%.
The present composition can be prepared into adaptation dosage form, preferred dosage form wettable powder with agriculturally acceptable auxiliary combination
Agent, missible oil, suspending agent, oil-suspending agent, microemulsion, aqueous emulsion, suspended emulsion, water dispersible granules etc..Auxiliary agent of the present invention
Including emulsifier, dispersant, wetting agent, binder, disintegrant, thickener, stabilizer, antifreezing agent, antifoaming agent filler etc..Select
From the common auxiliary material in this field.
Mixed herbicide of the present invention is used to prevent and kill off the purposes of paddy field weed.It is preferred for grassy weed.
The present invention obtains following advantageous effects：
Composition of the present invention uses the active ingredient combinations of three kinds of different role mechanism, can effectively reduce weeds
The generation of drug resistance expands herbicide controlling spectrum；
Herbicidal combinations of the present invention have significant synergies, higher to grassy weed preventive effect；
Herbicidal combinations field efficacy of the present invention is higher compared to the field efficacy of single dose, binary composition, can
To effectively reduce the administration dosage of active constituent, reduce environmental pollution.
