Abstract
The invention discloses a biopesticide emulsifiable concentrate preparation for controlling vegetable pest small white, belongs to blended biopesticide and aims to provide a blended biopesticide emulsifiable concentrate preparation which has good insecticidal efficacy, long-lasting pesticide effect and low cost and is used for controlling the small white. The biopesticide emulsifiable concentrate preparation is prepared by blending raw materials in percentage by weight as follows: 0.1%-30% of a macleya cordata ethanol extract, 1%-20% of rotenone, 1%-40% of a surfactant, 0.2%-20% of a cosolvent, 1%-2.5% of a sun-screening agent, 0.1%-2% of a preservative, 0.1%-30% of a stabilizer, 0.5%-10% of a synergist, 5%-40% of an organic solvent, 0.1%-24% of a penetrant, 0.01%-0.5% of a pH regulator, and the sum of the components is 100%. The drug resistance of pests is overcome by the aid of the synergistic effect of the macleya cordata ethanol extract and the rotenone, the control effect can be improved, the insecticidal spectrum can be enlarged, and defects of single pesticide are overcome; the biopesticide emulsifiable concentrate preparation is used for controlling the vegetable pest small white.
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 effectively overcoming with biopesticide rotenone mixture and obtaining the mixed insecticide preparation that vegetable-crop pest-insect develops immunity to drugs.
Background technology
Imported cabbageworm another name cabbage white butterfly, larva is also known as cabbage caterpillar, and brassicaceous vegetable of mainly causing harm, is injured more serious with cabbage mustard, wild cabbage, cauliflower etc. especially.Usually mixture chemical insecticide is adopted to prevent and treat imported cabbageworm at present.Owing to using chemical pesticide for a long time, while a large amount of killed natural enemies, imported cabbageworm creates high pesticide resistance to all kinds of chemical pesticide.
The features such as native insecticidal plant has efficiently, low toxicity, environmental protection, are receiving the concern of people.Rotenone is a kind of insecticide, is extensively present in the root skin zone of pulse family Derris plant.Rotenone to insect, the especially good preventive effect of the vegetable-crop pest-insect such as imported cabbageworm, aphid.
Macleaya cordata (
macleya cordata) be Papaveraceae (Papaveraceae), the perennial large-scale draft of Macleaya (Macleaya)." Chinese soil pesticide will " is recorded, and macleaya cordata whole strain extract can prevent and treat the various pests such as imported cabbageworm, tea caterpillar, tea geometrid 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 imported cabbageworm 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%, rotenone 1 ~ 20%, 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, tween selected by described surfactant, dimethyl sulfoxide (DMSO) selected by described cosolvent, castor oil selected by described sun-screening agent, and ethyl acetate selected by described preservative, and epoxidized soybean oil selected by described stabilizing agent, Butacide selected by described synergist, described organic solvent selects toluene, and Laurocapram 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 rotenone and macleaya cordata ethanol extract, improve the lasting effect of preparation; Preservative effectively can prevent the pollution of mould; Stabilizing agent can make rotenone, 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 rotenone 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 is owing to have employed technique scheme, by the active insecticidal components in macleaya cordata plant and biopesticide rotenone mixture, utilize the synergistic effect of macleaya cordata ethanol extract and rotenone to overcome the pesticide resistance of insect, improve control efficiency, 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, difficultly after therefore systematically solving macleaya cordata ethanol extract and rotenone emulsifiable solution mixture store, easily decompose, the easy difficult problem such as to pollute;
2, macleaya cordata ethanol extract and rotenone 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, because macleaya cordata ethanol extract and rotenone belong to the different insecticide of two class mechanism of action, the preparation after mixture not only expands pest control spectrum, improves drug effect; And the pesticide resistance of dominant population after delaying pest population succession, may be become, particularly remarkable to the application effect in imported cabbageworm governance process.
4, owing to preparing compatibility and the reasonable mixture ratio of each material needed for macleaya cordata ethanol extract and rotenone emulsifiable solution formulation, 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 10% invention formulation dilute 1000 times after to imported cabbageworm carry out spraying control, after dispenser, the Mortality of insect of 3 days, 7 days, 15 days is respectively 85%, 94.67% and 100%; Invention formulation lasting medicine is described, good disinsection effect.
