Description
Technical field
The present invention relates to field of agrochemicals, more particularly to a kind of aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin and its
Preparation process.
Background technology
Long-time service single formulation chemical pesticide, pest easily develop immunity to drugs, and long-time service year after year is not only tight
The wasting of resources is caused again, and environment, ecology and food security are all caused to seriously endanger, and human health is constituted necessarily
Threaten.
Phenthoate dimephenthoate cidial also known as philharmonic scattered, beneficial that dissipate, and are a kind of quick-acting contact killing type dithio acid esters insecticides of poisoning, act on
Mechanism is acetylcholine esterase inhibition, has and tags and stomach poison function, to a variety of biting mouth parts and sucking insect and mite
Worm is effective, for protecting the crops such as rice, cotton, fruit tree, vegetables, oil plant from Lepidoptera, Cicadellidae, aphid class and hapalonychia insects
Harm.The medicament is mainly used for insect pest, the effects such as prevention striped rice borer, yellow rice borer, rice leaf roller and plant hopper on rice and shows
Write, while can solve the problems, such as that the rice insect pest because of caused by the disabling of the high-toxic pesticides such as acephatemet is difficult to prevention, in actual life
It is widely used in production.
Avermectin is a kind of farm antibiotics, its main mode of action be tag, stomach toxicity, penetration is strong, be a kind of
F macrolide disaccharide compound, is the separated natural products from edaphon, has to insect and mite class and tags and stomach
Toxic action simultaneously has faint fumigation action, no systemic action.Its mechanism of action its interference nerve unlike general insecticide
Physiological activity, stimulates release r- aminobutyric acids, and r- aminobutyric acids have inhibitory action to the nerve conduction of arthropod, mite class
Occurs paralysis symptom after being contacted into, deutonymph and insect with larva with medicament, inactive not feeding is dead after 2-4 days, but it is right
Blade has very strong osmosis, can kill subepidermal pest, and the longevity of residure is grown.Simultaneously because dosage is small, it is degradable, thus
Environmentally safe, noresidue, to plant height safety.In short, avermectin is a kind of efficient, high selection, green, environment-friendly type
Biological source insecticide.Avermectin is used to prevent striped rice borer, yellow rice borer, rice leaf roller, bollworm, smaller green leaf hopper etc. in recent years
Pest has good effect, but quick-acting is slightly worse, and long-time service, and pest has generated resistance to it.
The content of the invention
It is poor to the resistance of single type medicament, prevention effect that the technical problems to be solved by the invention are pests, overcomes existing
There is the shortcomings that technology, there is provided a kind of aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin, improves pest controling effect, and delays pest
Resistance.
In order to solve the above technical problems, a kind of aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin of present invention offer, including with
Lower component：Phenthoate dimephenthoate cidial 44.5% ± 2.2%, avermectin 0.5% ± 0.1%, synergist 0.5%-3.5%, solvent 0%-
10%, emulsifying agent 0%-10%, thickener 0%-3%, defoamer 0%-3%, antifreezing agent 0%-10%, stabilizer 0%-3%,
Surplus is supplied by deionized water.
Technique effect：Compound water emulsion is made in phenthoate dimephenthoate cidial and avermectin by the present invention, by phenthoate dimephenthoate cidial and avermectin
Both anthelminthic effects combine, while improve the activity of avermectin, and pest resistance to insecticide is delayed to be used, on the one hand
Prevention effect of the pesticide to insect pest is substantially improved, has on the other hand significantly delayed the resistance to the action of a drug of pest again；In addition, in aqueous emulsion
Middle addition synergist, so as to greatly reduce the dosage of pesticide.The present invention enhances quick-acting compared with single type medicament,
The resistance to the action of a drug is delayed, has reduced dosage, reduced use cost, while pollution to ecological environment and the infringement of human health are big
It is big to reduce, it is a kind of composite insecticide of high comprehensive performance.
The technical solution that further limits of the present invention is：
Further, synergist includes Silwet, outstanding effect profit, palm oil methyloctanoic acid methyl esters, palm oil methyl methyl caprate, bavin
One or more in oil, neutral detergent.
A kind of preceding aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin, solvent include one kind in dimethylbenzene, cyclohexanone
It is or a variety of.
A kind of preceding aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin, emulsifying agent include styrene phenol polyoxyethylene ether
One or more in phosphate, castor oil polyoxyethylene ether.
A kind of preceding aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin, thickener are included in xanthans, Magnesiumaluminumsilicate
It is one or more.
A kind of preceding aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin, defoamer include organosiloxane, polyoxyethylene
One or more in polyoxy propyl alcohol amidogen ether, polypropylene glycerol aether
A kind of preceding aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin, antifreezing agent include one in ethylene glycol, glycerine, urea
Kind is a variety of.
A kind of preceding aqueous emulsion containing phenthoate dimephenthoate cidial and avermectin, stabilizer include DI-tert-butylphenol compounds, tertiary butyl

Another object of the present invention is to provide a kind of water containing phenthoate dimephenthoate cidial and avermectin for described in such scheme
The preparation process of emulsion, comprises the following steps：
Solvent, be added in emulsifying kettle by formula by S1, adds avermectin and stabilizer, and stirring is to being completely dissolved；
S2, addition phenthoate dimephenthoate cidial active compound, synergist, emulsifying agent are uniformly mixed；
S3, by defoamer, antifreezing agent, deionized water be configured to water phase；
S4, under high shear forces, water is mutually added drop-wise in oil phase emulsifying kettle, sheared again after being added dropwise 0.5 it is small when；
S5, start outer emulsification pretreatment machine, thickener is added, when circulation shear 1-1.5 is small；
Packing shop is sent after S6, detection are qualified.
The beneficial effects of the invention are as follows：
(1) in the present invention synergist compensate for using water for decentralized medium instead of oil cause to the affinity of pest and crop leaf with
The shortcomings that surface spreading ability reduces, increases the surface tension on crop after pesticide spraying, can rapidly make
Thing blade surface wetting and spreading is opened, and improves the dose of holding of crop, strengthens drug effect, reduces pesticide formulation rate；
(2) Silwet can reduce more than the 70% of former formulation rate as synergist in the present invention, water-saving section medicine, and be applied identical
Under the conditions of dose, prevention effect is significantly better than conventional type pesticide, and the lasting period substantially increases；
(3) aqueous emulsion of Compositional type is made in avermectin and phenthoate dimephenthoate cidial by the present invention, reduces emulsifiable concentrate to toluene, dimethylbenzene etc.
The demand for the organic solvent being harmful to environmental toxic, environmentally friendly safety；
(4) addition of various auxiliary agents ensure that the stability and the wherein stabilization of active insecticidal components of aqueous emulsion in the present invention
Property, easy to store and transport.
