CN103891764A - Fipronil compound pesticide - Google Patents

Abstract

The invention discloses a fipronil compound pesticide which is characterized by comprising the following components in percentage by weight: 5-10% of fipronil, 40-50% of trichlorfon, 5% of emamectin benzoate, 5% of emulsifier and the balance of solvent. The solvent is selected from xylene, water or dichloromethane. The assistant comprises an emulsifier selected from one or more of nonylphenol polyethenoxy ether, calcium alkylphenylsulfate and phenethylphenyl polyoxyethylene-polyoxypropylene ether. The composition has obvious synergistic effect and widens the pesticidal spectrum, and pests can not easily generate drug resistance.

Description

A kind of Firponil compounded pesticide

Technical field

The present invention relates to a kind of Firponil compounded pesticide, belong to technical field of pesticide.

Background technology

Ethiprole (Frontline, Fipronil), chemical name: 5-amino-1-(2,6-dichlor-4-trifluoromethyl phenyl)-4-trifluoromethyl sulfinyl pyrazole-3-nitrile, Insecticidal pyrazolines, is broad spectrum insecticide, and rice borer insects, plant hopper are all had to preventive effect.It has concurrently and tags and certain systemic action take stomach poison function as main, and the lasting period is long, lower toxicity agricultural chemicals in genus, but easily make pest develop immunity to drugs.In use procedure, there is slow (and quick-acting is poor) of drug effect, in the medicament of control rice borer insects, bad to paddy stem borer effect, and price is higher.

Practice shows, by heterogeneous agricultural chemicals phase mixture, make built agent, can effect complementation, multimachine reason desinsection, expands desinsection scope, reduce pesticide resistance, improve integrated control benefit, built agent is better compared with single dose pesticides application prospect, especially has the built agent of the advantages such as consumption is few, insecticidal spectrum is wide, residual quantity is low, use is safe.Research and develop the insecticidal compound agent of high-efficiency environment friendly of new generation, for preventing and treating paddy rice, vegetables and other piercing mouth parts class insect, can reach expection insecticidal effect, environmental protection again, health, be the problem that current people extensively study.

Summary of the invention

For the deficiencies in the prior art, technical problem to be solved by this invention is, a kind of Firponil compounded pesticide is provided, and the deficiency using to overcome ethiprole agricultural chemicals single dose expands desinsection scope, reduces pesticide resistance, improves integrated control benefit.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Firponil compounded pesticide, and its percentage by weight consists of:

Ethiprole: 5-10%, Dipterex: 40-50%; First dimension salt 5%, emulsifier 5%, surplus is solvent;

Described solvent is selected from dimethylbenzene, water or carrene;

Described auxiliary agent comprises emulsifier, is selected from one or more in polyoxyethylene nonylphenol ether, alkylbenzene calcium sulphate, phenethyl phenyl polyoxyethylene-polyethenoxy ether.

Preferred above-mentioned Firponil compounded pesticide, its percentage by weight consists of:

Ethiprole: 5%, Dipterex: 45%; First dimension salt 5%, the mixture 5% of alkylbenzene calcium sulphate and polyoxyethylene nonylphenol ether, phenethyl phenyl polyoxyethylene-polyethenoxy ether, surplus is water.

Equipment involved in the present invention is pesticide industry conventional equipment.Various former medicine involved in the present invention is commercially available prod, the current domestic production that all has, and the content of described various components is pure effective ingredient consumption.Wherein: chlorophos formal name used at school O, O-dimethyl-(the chloro-1-hydroxyethyl of 2,2,2-tri-) phosphonate ester, is a kind of organophosphorus insecticide.Industrial products are white solid, 83～84 ℃ of sterling fusing points, and the water-soluble and organic solvent of energy, character is more stable, is hydrolyzed into dichlorvos, acute toxicity LD50 value: big white mouse per os is 560～630mg/kg but meet alkali.

Present composition insecticide, belongs to low-toxin farm chemicals, is applicable to silkworm and mulberry area.Its each component mode of action has very strong complementarity, does not have antagonism, and its synergy is obvious, has expanded insecticidal spectrum, and insect is difficult for developing immunity to drugs.

Embodiment

Below in conjunction with specific embodiment, the present invention is further described.

Embodiment 1

The equipment that the present embodiment uses is pesticide industry conventional equipment, and compound process is: by proportioning, Dipterex is put into container and adds ethiprole, first dimension salt, solvent, emulsifier, stir full and uniform after, carry out effective substance, last packing.

The Firponil compounded pesticide of the present embodiment, its percentage by weight consists of:

Ethiprole: 10%; Dipterex: 40%; First dimension salt 5%, polyoxyethylene nonylphenol ether 5%, surplus is dimethylbenzene; The product forms of the present embodiment is missible oil.

Embodiment 2

Mode of operation is with embodiment 1, and its difference is, this Firponil compounded pesticide, and its percentage by weight consists of:

Ethiprole: 5%; Dipterex: 50%; First dimension salt 5%, the mixture 5% of alkylbenzene calcium sulphate and phenethyl phenyl polyoxyethylene-polyethenoxy ether, surplus is water; The product forms of the present embodiment is aqueous emulsion.

Embodiment 3

Mode of operation is with embodiment 1, and its difference is, this Firponil compounded pesticide, and its percentage by weight consists of:
