The herbicide mixture comprises, in mass percent, 1 to 75% of clacyfos, 1 to 20% of carfentrazone-ethyl and an accessory. The preparation method is to mix and process 1 to 75 parts by weight of clacyfos, 1 to 20 parts by weight of carfentrazone-ethyl and the balance of the accessory. The herbicide mixture is applied when wheat is in a period from trefoil stage before winter or from returning green stage to jointing stage and when broadleaf weeds are in a seedling stage. The invention relates to the clacyfos and carfentrazone-ethyl binary herbicide mixture used for controlling broadleaf weeds in wheat fields and its preparation method and application method; the herbicide mixture in the invention has the advantages of a simple production process, a good effect, broad weed control spectrum, special efficacy on broadleaf weeds, no harm to wheat, no influence on succeeding crops, low control cost, convenient usage and capacity of reducing pollution to environment and influence on health of human bodies.
Description
Technical field
The present invention relates to a kind of field weeding agent that is used for crops and preparation method thereof, method for using, particularly relate to a kind of complex weedicide and preparation method thereof, method for using.
Background technology
Chlorine acyl grass phosphine is by people such as the He Hong of Central China Normal University force development and exploitation, is applied by Shandong Qiaochang Chemical Co., Ltd, has the new herbicides of independent intellectual property right for China is a kind of, belongs to substituent phenoxy acetyl group hydroxyethylidene diphosphonic acid ester compounds.Chlorine acyl grass phosphine have active high, kill advantages such as careless spectrum width, interior absorption, and have low toxicity, low-residual, to the characteristics of ecological environment security.But the independent use of chlorine acyl grass phosphine has inevitable shortcoming again, as: bad to some malignant weed such as effects such as clearvers, corn gromwell; It is slow to kill careless speed.
The azoles humulone is a cauline leaf inorganic agent behind the selectivity seedling, prevents and kill off broad leaved weed and nutgrass flatsedge adaptable across gramineous crop fields such as wheat, barley, paddy rice, corns.Medicine destroys weeds and cell membrane through suppressing former fore-telling quinoline oxidase, makes blade withered rapidly dead.2-3 days susceptible weeds promptly show symptom of chemical damage after the normal dispenser, and 1 all left and right sides are withered.Use at wheatland and can effectively prevent and kill off broad leaved weeds such as descurainia sophia (l.) webb ex prantl, clearvers, corn gromwell, benbie, Veronica, wartwort, lamb's-quarters, shepherd's purse.The residual life of medicine in soil, is extremely short, to succession crop safety.But the azoles humulone often uses separately wheat is produced poisoning, because it has action of contace poison, dead grass is not thorough.
This shows how to found and a kind ofly have chlorine acyl grass phosphine and azoles humulone advantage concurrently, and overcome new complex weedicide of these two kinds of weed killer herbicide defectives and preparation method thereof, method for using with reasonable proportioning, is one of important improvement target of current this area.
Summary of the invention
The technical problem that the present invention will solve provides a kind of complex weedicide, makes its compound synergic remarkable, can improve in the wheatland preventive effect to broad leaved weeds such as clearvers, corn gromwells, increases safety, reduces poisoning, thereby overcomes the deficiency of existing weed killer herbicide.
For solving the problems of the technologies described above, a kind of complex weedicide of the present invention, comprise mass percent be 1-75% chlorine acyl grass phosphine, 1-20% azoles humulone and auxiliary material.
As a kind of improvement of the present invention, described auxiliary material comprises solvent and emulsifier.
Described solvent is corn oil, soybean oil, rapeseed oil or methyl oleate.
Described emulsifier is emulsifier 500#, and the mass percent that accounts for weed killer herbicide is 1-20%.
Described auxiliary material comprises filler, wetting agent and dispersant.
Described filler is diatomite or kaolin.
The mass percent of described chlorine acyl grass phosphine is 30%, and the azoles humulone is 2%.
The present invention also provides the preparation method of above-mentioned complex weedicide, make it can be used for preparing chlorine acyl grass phosphine and azoles humulone re-compounded binary herbicide, and production technology is simple, practical.
For solving this technical problem, the preparation method of the above-mentioned complex weedicide of the present invention is with the chlorine acyl grass phosphorus of 1-75 weight portion and the azoles humulone of 1-20 weight portion, supplies hybrid process behind 100 weight portions with auxiliary material.
In addition, the present invention also provides the method for using of above-mentioned complex weedicide, makes it easy to use, and the optimum period medication, and drug effect is higher, pollute lighter, littler to health influence, thus be suitable for practicality more.
For solving this technical problem, the method for using of the above-mentioned complex weedicide of the present invention is to be in the seedling phase at first three leaf after date of liriope minor or period of seedling establishment to shooting stage, broadleaved herb to use.
After adopting such design, the present invention compared with prior art has following tangible advantage and beneficial effect at least:
1, the present invention is a kind of complex weedicide; One of its composition chlorine acyl grass phosphine is the initiative kind that China has independent intellectual property right; Its mechanism of action is unique, active high; Most broad leaved weeds such as descurainia sophia (l.) webb ex prantl, clearvers, shepherd's purse there is good preventive effect, not only, also can endanger succession crop when stubble wheat safety;
2, the present invention has made full use of chlorine acyl grass phosphine development, through carrying out compositely with other weed killer herbicide kind, enlarges and kills the grass spectrum, improves and kills careless speed, and applying for it is large-area provides more advantage;
3, the method for using of complex weedicide according to the present invention, the optimum period medication, consumption is few, and preventive effect is high, alleviates the pollution to environment, is beneficial to the safety of people, animal, beneficial organism and keeping of the ecological balance, meets the sustainable development requirement.
As stated, the present invention is a kind of chlorine acyl grass phosphine that can be used for wheat paddock control broad leaved weed and azoles humulone re-compounded binary herbicide and preparation method thereof and method for using, and production technology of the present invention is simple; Good product effect is killed careless spectrum width, particularly broad leaved weed is had special efficacy; And, succession crop not being had influence to wheat safety, the control cost is low; Easy to use, and reduced pollution and health effects to environment.
