Abstract
The purposes that the present invention relates to the mixture preparations of the modified poly- trisiloxanes organosilicon of ethyoxyl and avermectin composition in crop pest prevention and treatment.The present invention is directly diluted with water, the prevention and treatment for red spider with the modified poly- trisiloxanes organosilicon of ethyoxyl and avermectin mixture.The advantageous effect of the invention is: being used using 500-6000 times of liquid of mixture preparation of the modified poly- trisiloxanes organosilicon of ethyoxyl and avermectin composition, to the control efficiency of the insect pests such as red spider, it can reach good effect, to mitigate Pesticide use amount and its adverse effect caused by environment.
Description
Technical field
The invention belongs to the mixed agents of the modified poly- trisiloxanes organosilicon of ethyoxyl and avermectin composition as insecticide
Application.
Background technique
The modified poly- trisiloxanes (Ethoxy Modified trisiloxane) of ethyoxyl is a kind of agricultural three silicon face
It is stagnant in the hold-up of plant surface, extension can to dramatically increase pesticide for activating agent after mixing by a certain percentage with the pesticide solution
It stays the time and improves to the penetration capacity of plant epidermis, this is for the dosage, the save the cost, reduction that improve drug effect, reduce pesticide
Pesticide is all highly effective to the pollution of environment.Its key property has: superpower spreadability, outstanding permeability, efficiently
Interior suction and conductibility, rain wash resistance, easy mixcibility, the safety and stability of height.Enhance medical fluid attachment, improves pesticide benefit
With rate.Excellent wetting and extension increases covering surface, improves efficacy of agricultural chemical.Promote internal-suction type medicament to permeate by stomata, reduces
Spray amount, rationally province's medicine is water-saving, saving of work and time.Pesticide residue is reduced, pesticide is reduced and is lost.The modified poly- trisiloxanes of ethyoxyl can
It is added in the spray mixture of insecticide, fungicide, herbicide, foliar fertilizer, plant growth regulator or biological pesticide, especially
Suitable for internal-suction type medicament.
Organosilicon, in known report, only as a kind of pesticide spray when a kind of auxiliary agent use, increase permeability,
Scalability, to improve the drug effect of pesticide used.
Avermectin is a kind of efficient, wide spectrum antibiotics insecticidal/acaricidal agent.It is by one group of macrolides chemical combination
Object composition, active material AVERMECTIN have stomach toxicity and action of contace poison to mite class and insect.Spraying leaf surface can divide rapidly
Solution dissipates, and the active ingredient penetrated into plant parenchymal tissue can be present in tissue and have conduction the long period, to evil
The insect that feeding endangers in mite and plant tissue has long residual effect.Avermectin is the natural production separated from edaphon
Object has insect and mite class and tags and stomach poison function and have faint fumigation action, no systemic action.
In the real process of agricultural production, application chemical agent is prevention and treatment plant pest the most effective means, but
The problem of being most easily produced by chemical prevention disease is the pesticide residue of environmental pollution and crops, and it is hidden that there are serious safeties
Suffer from, is far from satisfying the requirement of agricultural sustainable development.With the rise of pollution-less agriculture, the use of pesticide is proposed newly
Requirement, forbid the use of high poison, high residue medicament, and all do to the dosage of available pesticide, using concentration, use age etc.
Strict control.Therefore, the green Prevention Technique of alternative pesticide is the demand that pollution-less agriculture further develops.
Summary of the invention
The object of the present invention is to provide a kind of new and effective insecticides, have better effects to red spider.
The invention adopts the following technical scheme: the mixture of ethyoxyl modified poly- trisiloxanes organosilicon and avermectin composition
Purposes of the agent in crop pest prevention and treatment.
Preferably, the mixed agent that the modified poly- trisiloxanes organosilicon of ethyoxyl is formed with avermectin is that weight ratio is
The mixed agent of 10:1-20:1.
Preferably, the mixed agent that the modified poly- trisiloxanes organosilicon of ethyoxyl is formed with avermectin is that weight ratio is
The mixed agent of 30:2.
Preferably, insect pest is red spider.
Preferably, the modified poly- trisiloxanes organosilicon of ethyoxyl is directly diluted with water with avermectin mixture preparation, it is dilute
Rear Direct spraying processing is released, for preventing and treating the insect pest of crop.
Preferably, multiple is diluted with water with avermectin mixture preparation in the modified poly- trisiloxanes organosilicon of ethyoxyl is
500-6000 times, be 1000-3000 times as dilution times liquid further preferably.
Pesticidal combination of the invention can be processed into any dosage form pesticide-acceptable as needed, wherein it is preferred that agent
Type is wettable powder, water dispersible granules, suspending agent, suspoemulsion, aqueous emulsion, microcapsule suspending agent.
Surfactant selected by Pesticidal combination of the invention is known in those skilled in the art: can be selected from
One or more of dispersing agent, wetting agent, thickener or defoaming agent.According to different dosage forms, this field can also be contained in preparation
