Abstract
The present invention relates to a kind of suspending agents of ethylene diamin(e) containing glyphosate salt and flumioxazin, and formulation components are reasonable, and stability is good, and synergy is notable, for preventing Cotton Fields grassy weed and broad leaved weed.
Description
Technical field：
The invention belongs to field of pesticide preparation, are specifically related to a kind of suspending agent containing glyphosate and flumioxazin, use
Grassy weed and broad leaved weed are prevented and kill off in Cotton Fields.
Technical background：
Flumioxazin is N- phenyl neighbour's ammonia first phthalimide classes that SUMITOMO CHEMICAL chemical industry Co., Ltd. formulates and develops
Herbicide.Proporphyrinogen oxidase is can inhibit, the peroxidating of photosensitization and Cell membrane lipids is caused, tender and machine is total to cell membrane
It is configured to irreversible destruction, big Tanaka, the cauline leaf necrosis of susceptible weeds after cauline leaf process is dead after solar radiation, at soil
Sensitive weeds bud necrosis, dead after of short duration solar radiation after reason.
Glyphosate is that agriculturally conventional use of interior suction steriland herbicide, application range include orchard, bare place etc..It can
To prevent unifacial leaf, dicotyledonous, annual or perennial weeds.
Suspending agent is, by certain auxiliary agents, to be crushed by being sanded using water as medium, will be insoluble or poorly soluble in the solid of water
Active compound is homogeneously dispersed in water, formed a kind of higher suspension that particle is tiny, flowable stabilization liquid solid-state system.With grain
The features such as diameter is small, and good dispersion, suspensibility are high, bioactivity is high, resistance of rainwater washing against, is the important directions of formulations of pesticide development.
On the composition of preparation, suspending agent is mainly by pesticide original medicine, wetting agent, dispersant, thickener, antifreezing agent, pH adjusting agent, defoaming
The compositions such as agent and water.Since its decentralized medium is water, so suspending agent has at low cost, production storing and safe to use etc. special
Point, and can be mixed with arbitrary proportion with water, it is easy to use not by water quality Water Temperature.With using organic solvent as medium
The formulations of pesticide are compared, and have many advantages, such as that effect on environment is small and poisoning is light.
In the prior art, there is phase of the composition of glufosinate-ammonium ammonium salt and flumioxazin for preventing soybean weeds
It closes report (CN1317932A), and general disclose composition and can be prepared into wettable powder, water dispersible granules etc..However
In the actual use process, the preparation of preparation needs active ingredient and auxiliary agent collective effect, can just obtain a kind of good preparation.
Our team attempts by prolonged experiment, finds to utilize auxiliary agent well known in the prior art, under different proportionings,
Optimization obtains the best suspending agent containing glyphosate and flumioxazin of effect, and then completes the present invention.
Invention content：
The purpose of the present invention is to provide a kind of optimization of auxiliary agent is reasonable, control effect it is good contain glyphosate and flumioxazin
Suspending agent.The technical solution adopted in the present invention is：
A kind of suspending agent containing glyphosate and flumioxazin, dosage form group become：
Active ingredient：Glyphosate 1-50%, flumioxazin 0.1-30%；
Surfactant：1-20%；
Antifoaming agent:0.5-2%；
Thickener：1-5%；
Filler：Add to 100%；
Wherein surfactant is selected from：Alkyl phenol polyoxyethylene ether, fatty alcohol polyoxyethylene ether, alkyl glycosides, tallow amine

Hydrochlorate, polyoxyethylene polyoxypropylene base ether block copolymers, one or more of alkylphenol polyoxyethylene phosphate；Defoaming
Agent is organosilicon；Thickener is selected from：One or more of xanthans, hydroxymethyl cellulose, aluminium-magnesium silicate；Filler is water；It is excellent
The proportioning of choosing is surfactant:Thickener=15:1.
Glyphosate in the present invention is glyphosate ethylene diamin(e) salt.
The preparation method of suspending agent of the present invention is：Surfactant, antifoaming agent, thickener, filler are mixed, through high speed
Shear-mixed is uniform, and active compound is then added, ball milling 2-3 hours in the ball mill, and grain size is made to be completely in 5 μm hereinafter, this is made
The suspending agent of invention.
The dosage form of the present invention has the following advantages that：
1, stability is good, by rational mixture between each auxiliary agent, the dosage form of the present invention is made to be showed in stability etc.
Preferably；
2, lasting effect is good, and dosage form of the present invention can extend the lasting period of chemical control weeds, reduces Pesticide use number and total
Dosage；
3, wetability is good, and in field trial, for liquid when with blade contact, contact angle moment can be less than 90 °, reach flat
The state of paving improves wetting and expands effect, improves preventive effect；
4, the dosage form components of the application are reasonable, have apparent synergistic effect, toxicity and field experiment measurement result
Show that the composition of the present invention has synergistic effect.
With reference to embodiment to further instruction of the present invention, the percentage in embodiment is weight ratio, but this hair
It is bright to be not limited thereto.Percentage is weight percentage in all formulas of following embodiment.
Specific implementation mode：
1 48% glyphosate ethylene diamin(e) salt flumioxazin suspending agent of embodiment
Glyphosate ethylene diamin(e) salt 40%, flumioxazin 8%, alkyl phenol polyoxyethylene ether 6.5%, alkyl glycosides
8.5%, xanthans 1%, organosilicon 1%, water add to 100%.Preparation method is by surfactant, antifoaming agent, thickener, water
Mixing, is uniformly mixed through high speed shear, and glyphosate ethylene diamin(e) and flumioxazin is then added, ball milling 3 is small in the ball mill
When, measure grain size be respectively less than 5 μm both 48% glyphosate ethylene diamin(e) salt flumioxazin suspending agent.
2 60% glyphosate ethylene diamin(e) salt flumioxazin suspending agent of embodiment
Glyphosate ethylene diamin(e) salt 30%, flumioxazin 30%, sodium lignin sulfonate 7%, alkyl glycosides 8%, xanthan

(comparison medicament 2).
Prevent crop：Cotton.
Control object：Green bristlegrass, amur foxtail, barnyard grass, moleplant seed.
Test method：It tests in being carried out in Cotton Fields, each group handles 3 repetitions, and processing area is about 20m2, according to
The area of experimental plot, the good various medicaments of precise, spraying treatment before seedling.30d weeds death conditions after statistics administration, compare
The activity of weeding of various medicaments, in addition, will also after medicine in 40d observe crop growing state, be to crop to investigate medicament
It is no to have poisoning, it the results are shown in Table 2.
30d herbicidal effects after the suspending agent medicine of 2 glyphosate ethylene diamin(e) salt flumioxazin of table
Field experiment the result shows that, observe influence of the preparation to cotton seedling of the present invention, find, without poisoning, to show this hair
Bright component is reasonable, and wetability and resistance of rainwater washing against effect are good.By to embodiment drop and plant leaf blade dynamic contact angle
Observation finds the liquid of embodiment 4 about 6 seconds or so after contact blade, and contact angle could be less than 90 °, and remaining embodiment medicine
First instantaneous touch angle of liquid contact blade is just significantly less than 90 °, or even close to 0 °, reaches and sprawl completely.And in field condition
Under, since wind-force and blade pitch angle influence, liquid has often just been tumbled in early period, affects liquid in plant surface
It withholds and deposits.The difference of liquid holdup directly results in the difference of target site medicament active ingredient amount, to influence control effect.
This can also be embodied from the preventive effect of table 2.
Finally, it should be noted that：Modifications or improvements without departing from theon the basis of the spirit of the present invention, to this field
It is it will be apparent that the scope of protection of present invention therefore should be belonged to for technical staff.
