Abstract

The invention discloses a Chinese herb plant protection agent, which comprises the following raw material components: euphorbia pekinensis rupr, arisaema heterophyllum blume, pinellia ternata, strychnos nux-vomica l, cortex meliae, fructus toosendan, litsea cubeba oil, castor oil, silicate, a surfactant and a tackifier. The preparation method comprises: adding water to the Chinese herbs, decocting twice, combining the filtrates, adding to an emulsification reactor, adding an emulsification agent, uniformly mixing, adding litsea cubeba oil and/or castor oil, emulsifying, finally adding a tackifier and silicate mixing slurry, and completely mixing and homogenizing to obtain the product. According to the present invention, the Chinese herb plant protection agent is the novel pesticide preparation integrating the effects of insect disinfestation, sterilization and antivirus effect, can be separately used or/and can be mixed with ordinary insecticide pesticides, provides effects of contact toxicity, enterotoxicity, neurotoxicity and sterilization for pests, maintains the characteristics of low toxicity, high efficiency, easy degradation and no reside of the Chinese herbs, does not produce drug resistance to pests, does not pollute the environment, provides good prevention and control effects for horticultural plants and urban green plants, and further has good economic, social and environmental benefits.

Description

A kind of Chinese herbal medicine plant protection agent and preparation method thereof

Technical field

The invention belongs to agricultural insecticide antibacterial technical field, is related to a kind of Chinese herbal medicine plant protection agent and preparation method thereof.

Background technology

Litsea cubeba oil (Litsea cubeba oil), also known as Litsea cubeba oil, Oleum Litseae pungentiss, the quintessence oil extracted from Fructus Litseae fruit with steam distillation.Fructus Litseae is a kind of canella, and there are a large amount of plantations, main component in main product each province on the south East Asia, China the Changjiang river：Carbonyl compound (in terms of citral) >=66%.Main component is citral, content about 60%-80%.Other compositions include methyl heptenone, citronellal, citronellol, pinene, hesperidene, 1, 8-Cineole, camphene, linalool, the hexene -6- ketone of 2- methyl -2, Camphora, safrole, nerol, geraniol, terpineol, geranyl acetate, eugenol and paracymene etc..Containing more than 26 kinds chemically reactive substances, with broad-spectrum antibacterial action, its main component is citral, and its Antibacterial Mechanism complexity is various.It can directly make bacterioprotein or enzyme denaturation, with some chemical group direct effects, to DNA and RNA chemical action be produced, the organizational structure of destruction antibacterial, suppress biosynthesiss, reduce membrane passage or sealing cell wall, disturb the approach such as the catabolism of antibacterial to play antibacterial action.

Print Dong elements (azadirachtin) is a kind of main active insecticidal components of triterpenoid compound, and seed, leaf, bark and branch etc. contain various insecticide active substances in position, wherein the strongest to print the insecticidal activity of strain element.The insecticide of various different larval instars is shown suppression take food, the effect of repellent, toxicity and disturbance endocrine.As natural botanical insecticide, oneself uses for many years print Dong seed oils in developing country.Print Dong trees (Azadirachtaindica) is a kind of autochthonal tropical trees in Asia arid area, and there are a large amount of plantations each province on the south China the Changjiang river.Now also by some country's cultivations of Central and South America.

Pesticide species in the market are various, and great majority are chemical pesticides, and these toxicity of pesticide are strong, and power is big, and crop insecticide, sterilization are played a role.But; because these pesticide are due to strong toxicity; it is not easily decomposed; the side effect very big using generation to crops such as edible grain, melon and fruit and vegetables; often cause alimentary toxicosis and slow iron poisoning; the whole nation every year because eating vegetable, the accident of melon and fruit poisoning meet not fresh, and the sickness rate of other difficult strange illnesses such as cancer that chronic poisoning causes is sharply increased, by the physical and mental health of serious harm people；Make plant develop immunity to drugs simultaneously as applying chemical pesticide, in order to reach prevention effect, have to year by year increase every mu of dosage, cost is constantly raised, and prevention effect is general.People are intended to can have a kind of new nontoxic, pollution-free and non-harmful biological pesticide to come for chemical pesticide.Using natural pesticide plant exploitation efficiently, low toxicity and botanical pesticide free from environmental pollution, just gradually paid much attention to by people.By literature search, the pesticide species of exploitation have natural plant type and natural plants compound with chemical pesticide.

The content of the invention

The purpose of the present invention is for above-mentioned weak point, there is provided a kind of preparation method is simple, with parasite killing, sterilization, low, free from environmental pollution and synergistic function the Chinese herbal medicine plant protection agent of toxicity and preparation method thereof.

The purpose of the present invention is realized in that：

A kind of Chinese herbal medicine plant protection agent, including raw material components and parts by weight：Radix Euphorbiae Pekinensis 10-20 parts, Rhizoma Arisaematiss 10-20 parts, Rhizoma Pinelliae 10-20 parts, Semen Strychni 0-20 parts, Melia azedarach L. skin 5-10 parts, river Dong 0-20 parts, litsea cubeba oil 0.3-0.6 parts, Oleum Ricini 0.1-0.3 parts, silicate 3-5 parts, surfactant 0.3-1.0 parts, viscosifier 5-10 parts and appropriate amount of water；

Described silicate includes any one or more in sodium silicate, asbestos, clay and cement；

Described surfactant is using sodium dodecylbenzene and calcium dodecyl benzene sulfonate；

Described viscosifier include any one or more in shitosan, polyvinyl alcohol, carboxymethyl cellulose, carboxyethyl cellulose and methylcellulose.

Described Chinese herbal medicine plant protection agent, raw material components and parts by weight：Radix Euphorbiae Pekinensis 15-18 parts, Rhizoma Arisaematiss 15-18 parts, Rhizoma Pinelliae 14-16 parts, Melia azedarach L. skin 8-10 parts, litsea cubeba oil 0.5-0.6 parts, Oleum Ricini 0.2-0.3 parts, silicate 3-4 parts, surfactant 0.6-1.0 parts, viscosifier 8-10 parts and appropriate amount of water.

Specific embodiment

Embodiment 1
