Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of agricultural chemical insecticide, be specifically related to ethyl pleocidin and abamectin compounded suspending agent and preparation method thereof.
Background technology
Contain a large amount of organic solvents in the chemical pesticide, when making huge contribution, also brought serious pollution to natural environment for agricultural foison.Along with environmental regulation becomes better and approaching perfection day by day, the cry that reduces pesticide pollution is strong day by day.Develop safely, environmental protection and cheap novel liquid formulation are to reduce or eliminate the trend of the times of organic solvent harm having become agricultural chemicals development.Wherein, Water-borne modification is exactly one of dominant direction of formulations of pesticide development.This type pesticides new formulation also can increase new characteristic to agricultural chemicals; More can give full play to the function Characteristics of former medicine self, overcome and remedy the deficiency of the original formulation of agricultural chemicals, all lower to people and animals' toxicity and excitant; And can alleviate poisoning to crop; Improve physico chemistry and biological property, expanding application scope, the service life of prolongation medicament.
Agricultural chemicals suspension agent belongs to one of Water-borne modification novel form, is pesticide active ingredient and dispersant, wetting agent, thickener, antifoaming agent, antifreezing agent etc. are dispersed in the matrix water and the high dispersive that forms, stable suspended substance.Agricultural chemicals suspension agent has the advantage of wetting powder and missible oil concurrently: aspect drug effect, the suspending agent herbicide effects is superior to wetting powder, and the insecticide effect is then close with missible oil; Because agricultural chemicals suspension agent is dispersion medium with water, make it have environmental protection, cheap characteristics, reduced in a large number with an organic solvent production process safety, pollution-free simultaneously; And suspending agent can mix with arbitrary proportion with water, and is easy to use, can reach bigger coverage rate after the dilution, can be processed to the formulation of high concentration.
Summary of the invention
Ethyl pleocidin is made up of ethyl pleocidin-J and two kinds of components of ethyl pleocidin-L.Ethyl pleocidin acts on nAChR and GABA receptor in the insect nerve, causes polypide insensitive to the signal transfer reaction of excitability or inhibition, influences normal nervous activity, until death.Ethyl pleocidin has stomach toxicity and action of contace poison, is mainly used in control diamond-back moth, beet armyworm, Liriomyza, prodenia litura and lima bean pod borer.
AVM has insect and mite class tags and stomach poison function, and faint fumigation action is arranged, no systemic action; But blade is had very strong osmosis, can kill subepidermal insect, and the longevity of residure is long; What its mechanism of action was different with general insecticide is that it disturbs neurophysiology movable; Stimulate to discharge GABA, and GABA has inhibitory action to arthropodan nerve conduction, little to the damage of beneficial insect.
Ethyl pleocidin and abamectin compounded use can be worked in coordination with and played a role, and remedy the deficiency of single agent agricultural chemicals, delay pest resistance to insecticide, have increased effective desinsection scope, strengthen the control efficiency to insect.
The objective of the invention is deficiency, a kind of ethyl pleocidin and abamectin compounded suspending agent and preparation method thereof are provided to prior art.Composite suspending agent good drug efficacy of the present invention, its preparation method technology is simple, cost is low, safety and environmental protection.
For reaching above purpose, the present invention has adopted following technical scheme:
