Abstract
The invention relates to a euphorbia esula plant pest-killing emulsion in water. The emulsion in water is formed by compounding euphorbia esula ethanol extracting solution and rotenone. According to volume percent, the dosage of the euphorbia esula ethanol extracting solution is 10%-15%, the dosage of rotenone is 2%-5%, and one milliliter of the euphorbia esula ethanol extracting solution is equivalent to 2 grams of crude drugs. The pest-killing plant, euphorbia esula serves as a raw material, pest-killing active ingredients in raw plants are utilized for pest control, a green pesticide is prepared by scientific compounding, a main pest-killing active ingredient of the green pesticide is flavonoid glycoside, and restraining pests is achieved by food refusal and stomach poisoning effects. The euphorbia esula plant pest-killing emulsion in water is mainly used for controlling wolfberry aphid, and the comprehensive control effect can be over 90%.
Description
Technical field
The invention belongs to biological pesticide technical field, particularly relate to a kind of euphorbia esula plant pest-killing emulsion in water.
Background technology
Along with human kind sustainable development implementation, people have started to pay attention to rising direct or indirect potential danger and harm that application toxic chemical causes gradually.Therefore, meet environmental protection, health, sustainable development theory efficient, low toxicity, low-residual, just become the theme of current pesticide research with the pesticide developing of environmentally compatible.
Euphorbia esula L is that each large provinces and regions of Euphorbiaceae perennial herb poisonous plant ， China all have distribution, but be grown in more grassland, hillside and dry sandylyly and roadside.In Ningxia, be distributed in salt pond, concentric, Ji Ge mountain region, Guyuan City.Because Euphorbia esula L is poisonous all the year round, and this grass well developed root system, vitality are strong, often can replace valuable floristics, also can be used as the plant with insecticidal activity.
At present, yet there are no the vegetable insecticide of preparing with it.
Summary of the invention
Object of the present invention is just to provide a kind of euphorbia esula plant pest-killing emulsion in water.
The present invention is achieved through the following technical solutions:
A kind of euphorbia esula plant pest-killing emulsion in water, it is characterized in that the composite aqueous emulsion forming of Euphorbia esula L ethanol extract and rotenone, wherein the consumption of Euphorbia esula L ethanol extract is 10%～15%, its 1 milliliter is equivalent to 2 grams of crude drugs, the consumption of rotenone is 2%～5%, and above-mentioned consumption is in percent by volume;
The preparation technology of above-mentioned Euphorbia esula L ethanol extract is: the Euphorbia esula L after pulverizing is extracted or ultrasonic extraction or the rear suction filtration of alcohol heating reflux extraction to gained after rotary evaporation is concentrated by alcohol immersion;
Described alcohol immersion is extracted and is referred to that the ethanol that 10～15 times of employings, volume fraction are 60%～90% soaks 12～36 hours at normal temperatures;
Described ultrasonic extraction after referring to and adopting ethanol that 10～15 times, volume fraction are 60%～90% to dissolve again under 35～55 ℃ of temperature condition, ultrasonic extraction 30～60min under 70-100MHz;
The heating of described alcohol reflux extract refer to adopt ethanol that 10～15 times, volume fraction are 60%～90% to dissolve after refluxing extraction 1～3 hour under 50～70 ℃ of temperature condition again;
The auxiliary agent of above-mentioned aqueous emulsion is synergist, solvent and emulsifier;
Described synergist is wintergreen and turpentine oil;
Described solvent is acetone;
Described emulsifier is one or more in agriculture breast 500, alkylbenzene and OP-10.
The present invention take that pesticide plant---Euphorbia esula L is raw material, utilize the active insecticidal components in former plant to carry out control of insect, through science is composite, make a kind of environment friendly agricultural insecticide, its main active insecticidal components is flavonoid glycoside, reaches the object that suppresses insect by food refusal, stomach poison function.The present invention is mainly used in preventing and treating Wolfberry Aphid, and integrated control effect can reach more than 90%.
Euphorbia esula plant pest-killing emulsion in water technical advantage of the present invention is:
1 euphorbia esula plant pest-killing emulsion in water good water solubility of the present invention, has good insecticidal action to Wolfberry Aphid.Virulence test shows the lethality of insect can reach 90%.
In 2 the present invention, each component synergy, has toxic action very inviolent, and insecticidal activity is remarkable, after dispenser, and easily degraded, low toxicity, to person poultry harmless, with environmentally compatible.
Euphorbia esula L disinsection aqueous emulsion virulence test:
This test is carried out in matrimony vine research institute of Ningxia Academy of Agri-Forestry Sciences laboratory, and test adopts infusion process, and blade and aphid are dipped in medicament, then observes aphid mortality, and calculates lethality, the results are shown in Table 1.
The insecticidal effect of the different extension rates of table 1
Euphorbia esula L disinsection aqueous emulsion field trial:
Experimental field be located at matrimony vine research institute of Ningxia Academy of Agri-Forestry Sciences experimental field, within 2 years, No. 1, the peaceful Qi of life, and experimental field management is strict, and water and fertilizer condition is good.Test is established 750 times of dilutions of Euphorbia esula L disinsection aqueous emulsion and is processed.At 1 instar larvae initial stage of origination, take the dispenser of foliar spray method, take and evenly squirt leave dual sides as degree.Respectively before dispenser, 1d, 3d, 5d, 7d after a medicine, after secondary medicine, 7d, 14d investigate 6 times altogether.During investigation every tree from East, West, South, North, different azimuth choose 5 branches, investigate the insect population number of aphid on the long tender tip of every branch 30cm.
Result of the test shows that 750 times of Euphorbia esula L disinsection aqueous emulsions of the present invention have good control efficiency to Wolfberry Aphid, and after medicine, 3d preventive effect is the highest, and preventive effect reaches more than 90%.
