Abstract

The present invention discloses an agricultural composition for killing acarus, specifically a compound composition containing propargite and fenisobromolate. The invention is characterized in that the active components of propargite and fenisobromolate in terms of percentage by weight is 1-60 : 0.1-50, and the composition can be prepared into aqueous emulsion by adding proper amount of additive agents or carriers for preventing and controlling red spider lived in orange.

Description

The miticide composition that contains alkynes mite spy and fenisobromolate with synergistic effect

Technical field:

The invention belongs to technical field of pesticide, be specifically related to a kind of aqueous emulsion that the alkynes mite is special and fenisobromolate makes up that contains with acaricidal action.

Technical background:

Since at present in the main formulation of acaricidal medical treatment two spotted spider mite based on pulvis and missible oil, but we know, the inferior position of pulvis and missible oil mainly show following some:

1, pulvis has dust bigger in process of production, and contaminated environment is more serious.

2, the main organic solvent of missible oil contains a large amount of dimethylbenzene, toluene etc., along with oil price constantly goes up, causes the organic solvent price also to go up thereupon, has increased peasant's drug cost virtually.

3, because the use of organic solvent makes missible oil in the process of using, poisoning very easily occurs, in the process that stores, transports, produces, also have very big difficulty simultaneously.

4, because a large amount of and excessive use missible oil causes the residual bigger of crops, the example of returning because of residue problem when being everlasting outlet is of common occurrence.

Alkynes mite spy, trade name is a propargite, structural formula is:

Alkynes mite spy is the high more and outstanding more miticide of miticidal effect of a kind of temperature, insect had tag and stomach poison function, temperature is when 27 degree are above, has fumigation action, to becoming mite and children, effective as if mite, the effect of killing ovum is not fine, because long-term single product use, has now occurred pesticide resistance at present simultaneously.

Fenisobromolate (bromopropylate), trade name are named mite for controlling again, and structural formula is:

Fenisobromolate is a kind of chemical constitution organobromine compound similar to dichlorodiphenyl trichloroethane, to becoming mite, young mite, as if mite and ovum good control efficiency being arranged all, has very strong action of contace poison, and drug effect is not subjected to the influence of temperature, and the lasting period is more than 20 days.There is limited evidence currently of has the people to prevent and treat, and is a kind of new pharmaceutical preparation.

Summary of the invention:

The objective of the invention is to propose a kind of efficient, low toxicity, residual, control fruit tree two spotted spider mite is effective, environmental pollution is little, cost is low, warm blooded animal safety contained the special composition with fenisobromolate of alkynes mite.

The present invention realizes by following technical method:

Main active ingredient of the present invention is alkynes mite spy and fenisobromolate, wherein their percentage is alkynes mite spy 1%～60%, fenisobromolate 0.1%～50%, all the other comprise solvent 10%～30%, emulsifier 5%～20%, antifreeze 1%～5%, defoamer 0.1%～0.5%, thickener 0.1%～1%, water surplus for auxiliary agent and excipients.

Through the test recipe screening, the special optimum percentage by weight with fenisobromolate of alkynes mite is 5～30:0.5～20.

Described solvent is selected from N, in dinethylformamide, cyclohexanone, toluene, dimethylbenzene, dimethyl sulfoxide (DMSO), methyl alcohol, ethanol, 3-methyl cyclohexanol ketenes, N-octylpyrrolidone, N-pyrrolidones, propyl alcohol, butanols, ethylene glycol, diethylene glycol, ethylene glycol monomethyl ether, butyl ether, ethyl acetate, vegetable oil, the acetonitrile one or more use that total consumption is no more than 30% when multiple.

Described anion emulsifier is selected from farming breast 500 ^#(alkyl benzene calcium sulfonate), OP series phosphate (polyoxyethylene nonylphenol ether phosphate), 600 ^#In phosphate (phenyl phenol polyoxy ethyl ether phosphate), styrene polyoxyethylene ether ammonium sulfate salt, alkyl biphenyl ether disulfonic acid magnesium salts, the triethanolamine salt one or more use that total consumption is no more than 5% when multiple.

Described nonionic emulsifier is selected from farming breast 400 ^#(benzyl dimethyl phenol polyoxy ethyl ether), farming breast 600 ^#(phenyl phenol polyoxy ethyl ether), Nongru-700 ^#(alkylphenol-formaldehyde resin polyoxy ethyl ether), peaceful breast 36 ^#(phenethyl fluosite polyoxy ethyl ether), farming breast 1600 ^#(phenethyl phenol polyoxy ethyl polypropylene-base ether), ethylene oxide-propylene oxide block copolymer, OP series (polyoxyethylene nonylphenol ether), By series (castor oil polyoxyethylene ether), farming breast 33 ^#(alkylaryl polyoxyethylene polyoxypropylene ether), farming breast 34 ^#In (alkylaryl polyoxyethylene poly-oxygen propylene aether), sapn series (sorbitan monostearate), tween series (sorbitan fatty acid ester APEO), the AEO series (the pure APEO of fat) one or more use that total consumption is no more than 5% when multiple.

Described frost resistance is selected from one or more in ethylene glycol, glycerine, propane diols, glycerine, polyethylene glycol or sorbierite, uses that total consumption is no more than 5% when multiple.

Described defoamer is selected from one or more in silicone oil, silicone compound, C10-20 saturated fat acid compounds, the C8-10 aliphatic alcohols compound, uses that total consumption is no more than 0.5% when multiple.

Its manufacture craft of the special fenisobromolate aqueous emulsion of alkynes mite of the present invention is as follows:

(1) with propargite medicine, the former medicine of fenisobromolate, solvent, emulsifier, add together, make and be dissolved into even oil phase;

(2) water, antifreeze, defoamer are mixed, become the homogeneous water;

(3) under high-speed stirred, water is added oil phase, can make the special fenisobromolate aqueous emulsion of alkynes mite product.

The invention has the advantages that: (1) does not contain or contains a spot of organic solvent, and niff does not almost have, and is difficult in process of production catching fire, poisoning, and is safer to human and environment.(2) water with cheapness is main basis, has reduced production cost.(3) relative missible oil requirement is lower aspect storage, production and transportation, relatively safety.(4) warm blooded animal toxicity is reduced greatly,, can mix use with other agricultural chemicals and chemical fertilizer to the relative missible oil safety of plant, convenient relatively.(5) the fruit two spotted spider mite there is special efficacy, can gives full play to the effective active drug effect.
