Abstract

The present invention discloses a lethane of methylamino avermectin benzoate and hexaflumuron, which is prepared from methylamino avermectin benzoate, hexaflumuron, assistants and solvents, wherein the weight ratio of the methylamino avermectin benzoate to the hexaflumuron is 1: 5 to 30, the content of the methylamino avermectin benzoate and the hexaflumuron in the lethane is from 1% to 6%, and the content of the assistants and the solvents is from 99% to 94%. The lethane is used for preventing and curing lepidoptera pests comprising beet noctuids, prodenia litura, cotton bollworms, diamondback moths and the like, and has the characteristics of high efficiency, broad spectrum and no nuisance.

Description

Emamectin-benzoate-fluorine bell urea lethane
One, technical field
What the present invention relates to is a kind of agricultural insecticide, relate in particular a kind of by emamectin-benzoate and fluorine bell urea through the composite lethane that forms.
Two, background technology
Emamectin-benzoate (emamectin benzoate) is from fermented product Avermectin B 1(abamectin) 4 " deoxidation 4 "-Biao-methylamino-Avermectin B of forming of hydroxyl derivatization 1Mixture (the B of benzoate 1a+ B 1b).Its mechanism of action is for hindering the neural transmission of insect, causes the insect paralysis can not normal activity and death is a kind of novel biochemistry agricultural chemicals.Emamectin-benzoate to lepidopterous insecticidal activity than the high several times of Avermectin, to the toxicity of warm blooded animal than the low several times of Avermectin, the active constituent content that use in the field only as Avermectin 1/5 or lower.Be a kind of efficient, low toxicity, wide spectrum, insecticide without environmental pollution.Domestic existing some enterprises produce emamectin-benzoate, but because manufacturing cost height, the market price is higher, application units' area control cost height in the agricultural production, the peasant is difficult to accept, in production practices, apply being subjected to certain restriction, and the long-term use separately of large tracts of land, also be easy to generate pesticide resistance.
Fluorine bell urea (hexaflumuron) is the benzoyl area kind insect growth regulator, IGR, and its mechanism of action is to suppress the formation of insect chitinase, causes insect normally not cast off a skin and death.Be mainly used in control Lepidoptera, Homoptera and Diptera pest.It is the insecticide of a kind of efficient, low toxicity, low-residual, high selectivity.But because desinsection speed is slow, be difficult for being accepted by the peasant, and the long-term use separately of large tracts of land, also be easy to generate pesticide resistance.
A kind of desinsection, miticide composition that contains emamectin-benzoate disclosed in Chinese patent CN-01123750, in specification its point out can be composite with tens kinds of compounds such as fluorine bell ureas, but it only points out the use that can combine, and does not point out ratio, the usage amount of using together and provides specific embodiment and the synergy data.
Three, summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, propose to become lethane particularly missible oil, aqueous emulsion and microemulsion insecticide with hexaflumuron compounded with the different emamectin-benzoate of effect mechanism.Emamectin-benzoate and hexaflumuron compounded after show as obvious synergistic effect, improve insecticidal effect in the use, reduced use cost, stoped and delay the development of pest resistance to insecticide, enlarge the scope of application, and the compatibility to environment is better, simultaneously can also alleviate the pesticide resistance of insect, reduce farmer's burdens.
In the present invention, emamectin-benzoate-fluorine bell urea lethane, form by emamectin-benzoate and fluorine bell urea and auxiliary agent, solvent complex, wherein the weight ratio of emamectin-benzoate and fluorine bell urea is 1: 5～30, the amount that contains emamectin-benzoate and fluorine bell urea in the lethane is 1%～6%, and containing auxiliary agent and solvent is 99%～94%.
Further, emamectin-benzoate one fluorine bell urea lethane of the present invention, wherein the weight ratio of emamectin-benzoate and fluorine bell urea is 1: 10～25.
Be preferably, emamectin-benzoate of the present invention-fluorine bell urea lethane, wherein the weight ratio of emamectin-benzoate and fluorine bell urea is 1: 15～20.
In the present invention, the emamectin-benzoate amount ranges is: 0.1-2%, fluorine bell urea amount ranges is: 0.9～10%.Described auxiliary agent is: emulsifier is 0201, agricultural newborn 500 #, 602,2201 #, 700 #Tween-80, the mixture of any one or a few in compound emulsifying agent and the emulsifier known in those skilled in the art, cosolvent is a methyl alcohol, ethanol, dimethyl formamide, cyclohexanone, pyrrolidones, the mixture of any one or a few in methyl-sulfoxide and the cosolvent known in those skilled in the art, thickener is a polyvinyl alcohol, gum Arabic, the mixture of any one or a few in sodium carboxymethylcellulose and the thickener known in those skilled in the art, antifreezing agent is an ethylene glycol, glycerine, the mixture of any one or a few in polyethylene glycol and the antifreezing agent known in those skilled in the art, described solvent are water, toluene, dimethylbenzene, dimethylformamide, cyclohexanone, methyl alcohol, the mixture of any one or a few in b propanol and the solvent known in those skilled in the art.
In the present invention, also can contain other auxiliary agent if desired, as bleeding agent, surfactant, synergist etc., they are known in those skilled in the art.
The compound method of product of the present invention is with lethane in the prior art particularly missible oil, microemulsion and aqueous emulsion method for producing insecticide, and these preparation methods are a part of the present invention.
In the present invention, all raw material and auxiliary agent, additive all can be buied from market.
Below further specify the present invention by specific embodiment, but embodiment only is used for explanation, can not limit the scope of the invention, and in the present invention, is unit of weight as the non-all amounts, part, percentage of refering in particular to.
