Abstract
The invention discloses a biopesticide missible oil preparation for preventing vegetable pest plutella xylostella and belongs to mixed biopesticide. Mixed biopesticide missible oil preparation for preventing plutella xylostella aims to be high in penetrability, good in pest killing effect, durable in pesticide effect and low in cost and is mixed by, by weight, 0.1-30% of macleaya cordata ethanol extract, 0.1-10% of azadirachtin, 1-40% of surfactant, 0.2-20% of cosolvent, 1-2.5% of sun-screening agent, 0.1-2% of corrosion remover, 0.1-30% of stabilizer, 0.5-10% of synergist, 5-40% of organic solvent, 0.1-24% of penetrant and 0.01-0.5% of pH value modifier, and the sum of proportions of all the components is 100%. According to the biopesticide missible oil preparation for preventing vegetable pest plutella xylostella, the synergism of the macleaya cordata ethanol extract and the azadirachtin is used for overcoming the pesticide resistance of pests, the preventing effect can be improved, the insecticidal spectrum is expanded, and the defect of a single kind of pesticide is overcome. The biopesticide can prevent vegetable pest plutella xylostella.
Description
Technical field
The present invention relates to a kind of mixed insecticide, particularly relate to a kind of with macleaya cordata ethanol extract for active insecticidal components, by nimbin mixed with biopesticide and obtain effectively overcoming the mixed insecticide preparation that vegetable-crop pest-insect develops immunity to drugs.
Background technology
Diamond-back moth (
plutella xylostellalinnaeus), mainly to cause harm the crucifers such as wild cabbage, violet cabbage, broccoli, a kind of sedge dish, leaf mustard, cauliflower, Chinese cabbage, rape, radish.At present, diamond-back moth prevented and treated by usual employing mixture chemical insecticide, owing to using chemical pesticide for a long time, while a large amount of killed natural enemies, diamond-back moth creates high pesticide resistance to all kinds of chemical pesticide, replaces cabbage caterpillar gradually and becomes vegetables number one insect.
The features such as native insecticidal plant pesticide has efficiently, low toxicity, environmental protection, are subject to people's extensive concern.Nimbin (Azadirachtin) is separated from print chinaberry fruit, the wide spectrum of generally acknowledging in the world, efficient, low toxicity, easily degraded, noresidue biopesticide.Test proves, it to orthoptera, coleoptera, Homoptera, Lepidoptera etc. 8 order more than 400 plant agricultural, health and storage pest have the growth of significant Developing restraint, food refusal, avoid keep away, kill, interior suction and sterile isoreactivity.Multiple country such as the U.S., Germany, China successively develops azadirachtin insecticide, and commodity have obtained registration listing.But nimbin pesticide price commercially available is at present expensive, peasant is reluctant to buy; And, there are many functional groups (as ester group, epoxy construction etc.) very easily to decompose in the environment such as ultraviolet lighting, high temperature in nimbin molecular structure, cause insecticidal activity to reduce.In addition, nimbin Pesticide penetration is not strong, poor to insect preventive effect.
Macleaya cordata (
macleya cordata) be Papaveraceae (Papaveraceae), the perennial large-scale draft of Macleaya (Macleaya).According to the record of " Chinese soil pesticide will ", macleaya cordata whole strain extract can prevent and treat the various pests such as tea caterpillar, tea geometrid, imported cabbageworm effectively.Experimental study shows, the ethanol extract of macleaya cordata has very strong insecticidal activity to various pests.
Summary of the invention
In order to overcome the defect existed in prior art, the present invention aims to provide the biopesticide cream preparation of a kind of good disinsection effect, lasting medicine, control vegetable-crop pest-insect diamond-back moth that cost is low.
To achieve these goals, the present invention is formed by the raw material mixture of following weight percents: macleaya cordata ethanol extract 0.1 ~ 30%, nimbin 0.1 ~ 10%, surfactant 1 ~ 40%, cosolvent 0.2 ~ 20%, sun-screening agent 1 ~ 2.5%, preservative 0.1 ~ 2%, stabilizing agent 0.1 ~ 30%, synergist 0.5 ~ 10%, organic solvent 5 ~ 40%, penetrating agent 0.1 ~ 24%, pH value regulator 0.01 ~ 0.5%, and each component summation is 100%.
In technique scheme, many sorbitol esters selected by described surfactant, dimethyl sulfoxide (DMSO) selected by described cosolvent, castor oil selected by described sun-screening agent, and Sodium Benzoate selected by described preservative, and epoxidized soybean oil selected by described stabilizing agent, sulfoxide selected by described synergist, described organic solvent selects toluene, and fatty alcohol-polyoxyethylene ether (JFC-2) selected by described penetrating agent, and described pH value regulator selects sodium hydroxide or acetic acid.
In technique scheme, add surface-active and cosolvent can keep good emulsifying effectiveness and dissolubility; Sun-screening agent add the photodissociation ability that can reduce nimbin and macleaya cordata ethanol extract, improve the lasting effect of preparation; Preservative effectively can prevent the pollution of mould; Stabilizing agent can make nimbin, macleaya cordata ethanol extract in water or keep stable under acid, alkali condition, extends storage time; Can increase the adding of synergist and penetrating agent and ability is killed to insect; Organic solvent can dissolve the active substance in nimbin and macleaya cordata ethanol extract; PH value regulator can keep this preparation to remain within the scope of certain acid-base value.
Compared with the prior art, the present invention owing to have employed technique scheme, by the active insecticidal components in macleaya cordata plant and biopesticide nimbin mixed, utilize the synergistic effect of macleaya cordata ethanol extract and nimbin to improve control efficiency, to expand insecticidal spectrum.Due to the complicated component in mixture, synergy can be played in application, make up the deficiency of single agricultural chemicals.Moreover, the present invention also has the following advantages:
1, owing to adding surfactant, cosolvent, sun-screening agent, preservative, stabilizing agent, synergist, organic solvent, penetrating agent, pH value regulator in preparation, easily to decompose after therefore systematically solving macleaya cordata ethanol extract and nimbin emulsion mixture, the difficult problem such as poor permeability.
2, macleaya cordata ethanol extract and nimbin are in after aforementioned selected ratio mixture, not only maintain the advantage of biopesticide itself, and reduce mixture dosage, increased substantially drug effect; Compensate for the weakness of macleaya cordata ethanol extract to insect toxic effect difference, to the Application and Development of natural insecticide, there is profound significance.
3, macleaya cordata ethanol extract and nimbin mixed after preparation not only expand pest control spectrum, and improve drug effect; Particularly remarkable to the application effect in diamond-back moth governance process.
4, owing to preparing compatibility and the reasonable mixture ratio of each material needed for macleaya cordata ethanol extract and nimbin emulsion preparation, therefore the toxic action to various pest natural enemy can greatly be alleviated, reduce pollution and toxic and side effect, be conducive to protecting people, animal, crop safety; Not only can prevent and treat various vegetables insect, but also can pest resistance to insecticide have been overcome.
Field test results shows, by active component content be 8% invention formulation dilute 1000 times after to diamond-back moth carry out spraying control, after dispenser, the Mortality of insect of 3 days, 10 days, 30 days is respectively 87.33%, 96.33% and 100%; Invention formulation lasting medicine is described, good disinsection effect.
