Abstract

The biochemical emulsified insecticide is prepared with active matters including derris resin containing elliptone, phoxim, etc. synergist, e.q. turpentine, sesamin and capsaicine, and emulsifier and has high killing action on many kinds of agricultural pests with less toxic by-effect.

Description

Multifunctional emulsified insecticide

The invention belongs to insecticidal materials, is a kind of multi-effect farm biochemistry emulsified insecticide.

Kill crop pests (as cotton bollworm, mythimna separata, aphid etc.) the broad spectrum activity high concentration chemical pesticides such as flolimat, Deltamethrin that use at present more, though have stronger deinsectization effect, long-term use exists easily develops immunity to drugs, destroys the ecological balance and big to people and animals' harmfulness, as can to poison insect in a large number with poison deficiencies such as natural enemy.For alleviating the effect of paying of this class chemical pesticide thing, use is also arranged with rotenone or from another kind of biological insecticides as if the active ingredient preparation of extracting chinaberry and the azedarach, go out except that insects such as aphid, two spotted spider mite, cabbage caterpillars, though can overcome the existing deficiency of chemical pesticide to a certain extent, but because its drug effect is relatively poor, the broad spectrum activity that does not have broad has influenced applying of such agricultural chemicals.

The object of the present invention is to provide a kind of to contain the biochemistry emulsified insecticide of rotenone, Cyhalothrin and three kinds of effective ingredients of phoxim, and add an amount of turpentine oil, cloves wet goods and peppery element, sesamin and do builder, strengthened the drug effect of rotenoid insecticide, make it can kill the multiple kinds of crops insect, to overcome the existing in prior technology deficiency.

The content of each active principle, builder and emulsifier, solvent and preparation method are as follows in this emulsified insecticide:

Many effects emulsified insecticide is an active principle to contain a certain amount of rotenone, Cyhalothrin, phoxim, and add an amount of builder, surplus is emulsifier and solvent, the content of rotenone is 2.5-3% in this insecticide, the content of Cyhalothrin is 0.2-0.5%, and the content of phoxim is 18-19%; Each builder and content thereof are respectively: a kind of in turpentine oil, croton oil, eucalyptus oil, caryophyllus oil, the imitative camphor oil, its content is 2-4%, the content of peppery element is 4-5%, the content of sesamin is 3-4%, contain agricultural newborn anion surfactant 3-6%, surplus is a kind of in solvent benzol, dimethylbenzene, acetone, chloroform, the ethanol.

This method for producing insecticide is:

A, produce the derris resin that contains rotenone: former greenwood derris root is decaptitated, segment and put into crusher for crushing after get its powder with the square-bottomed bamboo basket of certain order number sieve sieve, this derris root powder being put into reactor extracts with the benzene dipping is free again, its master operation is that stirring, blowing filter, and in reactor the clear filtrate of concentrating under reduced pressure after by centrifugation, keeping reactor temperature is 40 ℃-45 ℃, and mixing time is 48 hours, can produce the derris resin that contains a certain amount of rotenone;

Producing of B, peppery element: do raw material with capsicum and take the free process of alcohol dipping to prepare peppery element, its abstraction process is identical with preparation trifoliate jewelvine resin;

The compound method of C, insecticide: according to the reactor amount of capacity, choose an amount of trifoliate jewelvine resin, phoxim and Cyhalothrin according to a certain percentage, earlier phoxim, Cyhalothrin are put into reactor, inject derris resin then, temperature in the kettle is 40 ℃-60 ℃, adds a certain amount of aforementioned each synergist and emulsifier again behind the stirring certain hour, continues to stir certain hour, solvent with effective dose drops in the still again, and the back blowing that stirs is this emulsified insecticide; Be brownish red.

The relative weight ratio for preparing required each material of this insecticide is respectively:

Each active principle is respectively to contain the derris resin of 6-8% rotenone and 50% Cyhalothrin, phoxim, three's relative weight ratio is 1: 0.02-0.04: 0.8-1.2, each synergist of required interpolation, sesamin, peppery plain three's relative weight ratio is 1: 1-1.2: 0.8-1.3, and emulsifier is 1 for a kind of relative weight ratio with solvent xylene in the farming breast 2028,0203,0208,0206: 1.5-1.7; The gross weight of three kinds of active principles is 3-5 with the ratio of each builder emulsifier, solvent gross weight: 1.

The process conditions of preparation insecticide are:

To pulverizing the order number that back derris root square-bottomed bamboo basket that powder is crossed sieves is 60 orders-90 orders, is 20-50 minute to the mixing time of derris resin powder, phoxim, Cyhalothrin three materials, and the mixing time that adds behind each builder, the emulsifier is 40-90 minute; Emulsifier also can be selected a kind of in the farming breast No. 100, No. 300, No. 500, No. 600 for use.

Embodiments of the invention are respectively:

1,100 kilograms of these emulsified insecticides of preparation need contain 1 kilogram of 45 kilograms of derris resins, 50% Cyhalothrin, 37 kilograms of 50% phoxims of 6% rotenone, 3 kilograms in turpentine oil, 3 kilograms of sesamins, peppery plain 3 kilograms, (2028) 3 kilograms of farming breasts, 5 kilograms of dimethylbenzene.The extraction of derris resin, peppery element and the compound method of insecticide are as described above.The content of rotenone is 2.7% in the emulsified insecticide of producing by this compatibility, the content of Cyhalothrin is 0.5%, the content of phoxim is 18.5%.

2,100 kilograms of emulsified insecticides of preparation need contain 1 kilogram of 38.57 kilograms of derris resins, 50% Cyhalothrin, 37 kilograms of 50% phoxims of 7% rotenone, 3.5 kilograms in turpentine oil, 3.5 kilograms of sesamins, peppery plain 3 kilograms, (2028) 5 kilograms of farming breasts, 8.43 kilograms of dimethylbenzene.By the content of rotenone in this emulsified insecticide of preceding method preparation be 2.7%, the content of Cyhalothrin is 0.5%, the content of phoxim is 18.5%.

3,100 kilograms of emulsified insecticides of preparation need contain 1 kilogram of 34.75 kilograms of derris resins, 50% Cyhalothrin, 37 kilograms of 50% phoxims of 8% rotenone, 3.5 kilograms in turpentine oil, 4 kilograms of sesamins, peppery plain 4.5 kilograms, (2028) 6 kilograms of farming breasts, 9.25 kilograms of dimethylbenzene.The preparation method as described above, the content of rotenone is 2.7% in this emulsified insecticide, the content of Cyhalothrin is 0.5%, the content of phoxim is 18.5%.

The substantive distinguishing features that the present invention has and obtained remarkable technological progress are as follows:

1, increases micro-Cyhalothrin and an amount of phoxim can be widened the kind that contains rotenoid medicine killing crop pests, make it effectively to prevent and treat the crop pests such as bollworm, mythimna separata, wheat sawfly, aphid, red spider, bridging worm, pink bollworm, cabbage caterpillar, vegetable aphid.

2, the builder that adds such as turpentine oil can strengthen the toxicity of three kinds of effective ingredients in the rotenone, and Capsaicin and sesamin can strengthen respectively the toxicity of rotenone and Cyhalothrin, make this medicine have stronger disinsection efficiency, eliminate the resistance to the action of a drug of insect. This pesticide has efficient killing action to bollworm.

3, because the compatibility of required each material of this pesticide of preparation is reasonable, can greatly alleviate the toxic action to the various pest natural enemies of kill, infringement and less pollution to ecological environment are conducive to protect the person poultry safety. Be a kind ofly can prevent and treat the multiple kinds of crops insect, it is little and cost is low that poison is paid effect, and simple biochemistry emulsified insecticide is used in preparation.
