Abstract

The present invention provides plant insecticide and a manufacturing method thereof. The plant insecticide comprises natural plants, such as nuxvomica, croton, bitter apricot seed, Chinese honeylocust fruit, white pepper, fructus hordei germinatus, etc., active ingredients are soaked out through volatile solvent, such as methanol and ethanol, or the mixed liquor of the volatile solvent and chloroform, and the plant insecticide is formed by mixing the active ingredients. The plant insecticide has strong lethality for crop or plant pests, and has no harm for people, livestock, poultry, fishes, etc.; the disease resistance of plants and crops can be enhanced, and the present invention has the advantages of low cost and no pollution in the process of production.

Description

Vegetable insecticide and preparation method thereof
The invention provides vegetative insecticide and preparation method thereof and using method, belong to technical field of pesticide.
Existing chemical pesticide is because its hypertoxicity, in use often because of operating incorrect cause people, animal, fowl poisoning, and easily on crop, leave residual hazard, cause secondary pollution, environment also there is very big adverse effect, particularly use through the normal phase, make some plant insects produce pesticide resistance, insecticidal effect is also more and more lower.
Purpose of the present invention just provides insecticide and manufacture method and the purposes that a kind of plant is made, and environmentally safe has stronger insecticidal effect, does not stay residual hazard, and harmless to people, animal, fowl, and production process does not have contamination hazard to human body and environment yet.
The object of the present invention is achieved like this:
1. select the natural plants dry product that comprises vomiting nut, crotons, semen armeniacae amarae, Chinese honey locust, white pepper, fructus hordei germinatus for use, pulverize stand-by;
2. select for use volatile solvent soln to make solvent, above-mentioned steps each dry product in is 1. soaked in sealing respectively, and the weight ratio of dry product and solvent is 1: (2-3).Volatile solvent comprises the ethanol of 75% ethanol, methyl alcohol, 95% ethanol or 95% and the mixed liquor that chloroform is made by 1: 3 volume ratio.Each natural plants adopts any immersion in above-mentioned four kinds of solvents, and wherein, the solvent of white pepper, fructus hordei germinatus is preferably selected 95% ethanol for use; The immersion solvent of Chinese honey locust is preferably selected 75% ethanol or methyl alcohol for use; Vomiting nut, crotons, amygdalate immersion solvent are preferably selected 95% ethanol or 95% ethanol and chloroform mixed liquor for use;
3. sealing soak time is 2-15 days.Can be shaken in the immersion process, be soaked effect to strengthen;
4. the soak after 3. step being soaked takes out clear liquid through precipitation behind the filter residue, selects for use wherein at least three kinds to soak clear liquids and press tabulation 1 listed combination and volume parts ratio, and the immersion clear liquid of selecting for use is mixed, and makes vegetable insecticide.

The vegetable insecticide of the present invention that said method is made should seal preservation in the cool.During use, with clear water dilution 500-1500 doubly, preferably dilute 500-1000 doubly, be used for crops or plant-spraying.Muddiness may occur in the preservation process, through shaking muddy can the disappearance, muddiness or small amount of precipitate occurring does not influence use, and precipitation mainly is because of filter residue does not thoroughly form, and the filtering precipitation gets final product during use, in order to avoid stop up the instrument that sprays.
The desinsection of vegetable insecticide of the present invention is renderd a service, and is subjected to applying environment temperature effect that minor variations is arranged, and when temperature improved, desinsection is renderd a service to be increased, and can cross the variation among a small circle of diluted concentration and regulate when dilution.
Vegetable insecticide of the present invention also can add the emulsifier that is no more than vegetable insecticide total amount 5% and be used, and to strengthen spray effect, emulsifier is farming breast No. 500 or a dodecyl laruyl alcohol.
Vegetable insecticide of the present invention can extensively be applied to crops and plant and insect is had kill effect significantly.Active component content is low in this insecticide, and is all harmless to people, animal, fowl, fish through dilution more than 500 times when particularly spraying.Facts have proved the resistance against diseases that can also strengthen crops or plant after spraying.
Below be vegetable insecticide insecticidal test result of the present invention, reach and agricultural chemicals contrast and experiment such as phoxim, 1605, nuvacron, be test mean value 10-30 time.Vegetable insecticide, phoxim, 1605, nuvacron dilute 1000 times respectively in the experiment, and spraying imposes on crops or the plant.
