The botanical synergistic compound pesticide is free from any chemical component, low-toxic to human and animals, and environment-friendly; and the botanical synergistic compound pesticide can prevent and control brown planthopper, small brown planthopper, bemisia tabaci, aphid, citrus fruit fly, ampullaria gigas, wiggler and other insects.
Description
Technical field
The invention belongs to agricultural insecticide field, be specifically related to a kind of plant resource synergistic complex insecticide of preventing and treating multiple insect pest.
Background technology
Along with the use of chemical pesticide, worldwide environment and the ecological balance have all been suffered serious destruction.The toxicity of agricultural chemicals, residual and environmental pollution is very serious in China, in order to address this problem, should strengthen high-efficiency low-toxicity on the one hand, the development of the novel pesticide of easily biological-degradable and environmentally compatible, will study, develops and use environment friendly agricultural preparation on the other hand.
Tellurian plant pesticide resource is very abundant, and wherein poisonous plant kind accounts for 4% of floristics sum.In < < Botanical pesticides in agriculture > > mono-book, describe more than 800 in detail and plant pesticide plant, 150 kinds are killed nematode plant, 51 kinds are killed mouse and kill spiral shell plant, introduce plurality of active ingredients and target pest simultaneously, the development of botanical pesticide is laid a good foundation.For brown planthopper, the report of preventing and treating aspect also has much.As causing the female adult lethality of the long wing type of brown planthopper, the various plants extracts such as kwangsi stephania root, the coptis, Mahonia fortunei increase; Chinese prickly ash, grass-leaved sweetflag, fenugreek, rhizoma calami and nutmeg ethanol extract have obvious action of contace poison to brown planthopper nymph; Relevant brown planthopper repellant aspect, gelsemium elegan, red chinaberry and Fructus Bruceae extract have to brown planthopper the deterrent effect of significantly laying eggs; Clock waits the Antifeedant Effects of 47 kinds of non-host plant ethanol extracts of research Liao31 section to brown planthopper adult all one's life, and the extract of find garlic, neem oil, spending Africa mountain soya bean in vain is best to brown planthopper adult Antifeeding Effects.
Botanical pesticide active ingredient is this raw metabolite with insecticidal activity mostly, has in efficient, environment and easily decomposes, to features such as person poultry safeties.Along with the proposition of new ideas such as " public nuisance-free agricultural chemicals " and " the harmonious agricultural chemicals of environment ", the requirement that agricultural chemicals is used is more and more higher, and for promoting agricultural sustainable development, the development and utilization that strengthens plant insecticide is significant.
Ginkgo (
ginkgo bilobal.) be the special product plant of Ginkgoaceae Ginkgo plant ，Shi China, belong to a section one and belong to a kind of special plant, be called as " living fossil " plant.Up to now, oneself isolates a large amount of nonpolar and polar compounds researcher from ginkgo leaf: long-chain hydrocarbons and their derivates, cyclic compound, fatty acid, carbohydrate and derivative thereof, flavonoids, isoprene class etc., mainly comprise flavonoid glycoside, terpene lactones, polyisoamylene alcohols, 6-HKA, organic acid, separating Ginkgo phenolic acids and alkyl phenol, alkyl phenolic acid (ginkgoic acid), 4 '-methoxyl group pyridoxine etc.Wherein ginkgoterpene lactone is as the exclusive compounds of ginkgo, be that the main active insecticidal components Huang S.H. of ginkgo etc. furthers investigate the mechanism of toxication of Bilobalide, find to take that ginkgolide compound that Bilobalide is representative may act on the central nervous system of insect.GABA acceptor on postsynaptic membrane may be its action target.Example: ginkgolide compound chemical structural formula is as follows:
The data-searching of doing according to applicant, yet there are no ginkgo leaf methanolic extract and Chinese holly methanolic extract composite or take ginkgo leaf methanolic extract, Chinese holly methanolic extract is composite is basic mixed insecticide.
Summary of the invention
The object of the present invention is to provide a kind of plant resource synergistic complex insecticide, this plant resource synergistic complex insecticide is not containing any chemical pesticide composition, to people, animal low toxicity, environmentally friendly, can prevent and treat the insect pests such as brown planthopper, small brown rice planthopper, Bemisia tabaci, aphid, citrus fruit fly, Pomacea canaliculata and wriggler.
For achieving the above object, the present invention adopts following technical scheme:
Plant resource synergistic complex insecticide be take ginkgo leaf methanolic extract as a desinsection inorganic agent, and Chinese holly methanolic extract is synergist the aqueous emulsion that adds other additive compound to form.
Described ginkgo leaf methanolic extract or the preparation method of Chinese holly methanolic extract are as follows: get ginkgo leaf or holly leaf 1 kg soaks three days under room temperature in 5 L methyl alcohol, filter, leaf is through soaking for the second time, method is as described in front method, merge extracted twice liquid, evaporate to dryness, obtains extract 80 ~ 110 g.
Described aqueous emulsion is prepared by following raw materials by weight: ginkgo leaf methanolic extract: 1%-20%, Chinese holly methanolic extract: 5%-20%, organic solvent: 0%-70%, surfactant: 5%-20%, thickener: 0.2%-1%, surplus is water.
Described organic solvent is one or more mixture of ethyl acetate, acetone, ethanol, methyl alcohol; Described surfactant is one or more the mixture in alkylphenol polyoxyethylene phosphoric acid ester, aralkyl phenol polyethenoxy ether phosphoric acid ester, alkyl phosphate class, aliphatic acid polyethenoxy ether class, phenethyl phenol polyethenoxy ethers castor oil and ethylene oxide adduct, aralkyl phenol polyethenoxy ether formaldehyde condensation products.
Described thickener is one or more the mixture in polyvinyl alcohol, sodium cellulose glycolate, xanthans.
The preparation method of above-mentioned aqueous emulsion: according to formula ratio, ginkgo leaf methanolic extract, Chinese holly methanolic extract, organic solvent, surfactant, thickener and water are mixed, stir transparently in reactor, make finished product.
Plant resource synergistic complex insecticide of the present invention has higher control efficiency to brown planthopper, small brown rice planthopper, Bemisia tabaci, aphid, citrus fruit fly, Pomacea canaliculata and wriggler etc.
Remarkable advantage of the present invention is:
(1) ginkgo leaf methanolic extract, Chinese holly methanolic extract are natural active matter, are easy to degraded, to mammal low toxicities such as people, animal and to other beneficial organism safety in environment.
