Abstract
The invention belongs to technical field of pesticide, in particular to a kind of plant pesticide composition, its effective component is nimbin, nicotine and ginkgolic acid, nimbin, nicotine, ginkgolic acid mass ratio be (2-6): (30-60): (20-50).The invention also discloses the preparation methods of plant pesticide composition.The present invention is using nimbin, nicotine and ginkgolic acid as material, and for preparation to safety of human and livestock, Environmental compatibility is good, is conducive to pollution-free vegetable and produces；Effective component mechanism of action of the invention is different from chemical pesticide, and pests are not easy to produce resistance.Mixture has synergistic function to component of the invention in a certain range, and compared with single dose is used alone, dosage is less, and drug effect more preferably, lays the foundation for exploitation novel plant source pesticide product.
Description
Technical field
The present invention relates to one kind to be compounded based on botanical pesticide, in particular to a kind of to contain nimbin, nicotine and ginkgolic acid
Plant pesticide composition, the composition to diamondback moth have synergistic function.
Background technique
The small green worm of diamondback moth (Plutellaxylostella L.) alias, pointed at both ends, category Lepidoptera Lepidoptera dish
Moth section Plutellidae is the world wide inner cross flower No.1 pest of section., the generation strong with fertility occurs more and is overlapped
Seriously, to strong environmental adaptability the features such as.For a long time, with the increase of vegetables demand, a large amount of uses of chemical pesticide
Leading to the drug resistance of diamondback moth enhances, and preventive effect decline destroys ecological environment.Harm, protecting ecology are broken out in order to control diamondback moth
Environment, the development of novel biopesticide are that one of the important method alleviated drug resistance and enhance drug effect, especially biological pesticide are multiple
With not only can use respective advantage, but also respective disadvantage can be made up.Compounding between botanical pesticide is research and development control pickles
The hot spot of moth new product, and the main path of exploitation chemical pesticide substitute.
Nicotine (Nicotine), nimbin (Azadirachtin) and ginkgolic acid (ginkgolic acids) have height
The advantages that effect, wide spectrum, environmental protection is the production ideal biological pesticide of green food.Nicotine is a kind of be present in plant of Solanaceae
The important component of alkaloid and tobacco, this substance reduce insect activity, lose feeding ability, and then paralysis is dead.Print
Chinaberry element is a kind of lemon chlorins compound being present in neem tree, this substance has food refusal to insect, walks quickly and keeps away larva, interference
Oviposition inhibits the effect of growth to achieve the purpose that desinsection, especially influences on the antifeedant activity of lepidopterous insects very big.Silver
Apricot phenolic acid has the effects that stronger food refusal, poisoning to insect.The reciprocal effects of heterologous plant compound are studied, are vegetable-crop pest-insect
Field control find new approach, and the Field information of three kinds of medicaments provides scientific basis thus.
Summary of the invention
The object of the present invention is to provide a kind of plant pesticide composition and preparation method thereof, composition pesticide association of the present invention
It is obvious with synergistic effect, it is environmentally protective.
The first purpose of this invention is achieved through the following technical solutions, and a kind of plant pesticide composition has
