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 L plant insecticide aqueous emulsion.
Background technology
Along with the human kind sustainable development implementation, people begin to have paid attention to using direct or indirect potential danger and the harm that 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 an Euphorbiaceae perennial herb poisonous plant, in each big provinces and regions of China distribution is arranged all, but be grown in more grassland, hillside and dry sandylyly and the roadside.Be distributed in Ningxia the salt pond, with one heart, Guyuan City and each mountain region.Because Euphorbia esula L is poisonous all the year round, and this grass roots system is flourishing, vitality is strong, and the normal valuable floristics of instead also can be used as the plant with insecticidal activity.
At present, also do not see the vegetable insecticide of useful its preparation.
Summary of the invention
The object of the invention just is to provide a kind of Euphorbia esula L plant insecticide aqueous emulsion.
The present invention realizes through following technical proposals:
A kind of Euphorbia esula L plant insecticide aqueous emulsion; It is characterized in that it being the composite aqueous emulsion that forms 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 gram crude drugs, and 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 will pulverizing is with alcohol immersion extraction or ultrasonic Extraction or alcohol heating reflux extraction back suction filtration, and rotary evaporation concentrates the back gained;
Described alcohol immersion is extracted and is meant that adopting 10～15 times, volume fraction is that 60%～90% ethanol soaked 12～36 hours at normal temperatures;
Described ultrasonic Extraction be meant adopt 10～15 times, volume fraction be behind 60%～90% the dissolve with ethanol again under 35～55 ℃ of temperature condition, ultrasonic Extraction 30～60min under the 70-100MHz;
Described alcohol reflux heating and extracting is meant that adopting 10～15 times, volume fraction is to extract 1～3 hour 50～70 ℃ of temperature condition refluxed behind 60%～90% the dissolve with ethanol again;
The auxiliary agent of above-mentioned aqueous emulsion is synergist, solvent and emulsifier;
Said synergist is wintergreen and turpentine oil;
Said solvent is an acetone;
Said emulsifier is one or more among farming breast 500, alkylbenzene and the OP-10.
The present invention is with pesticide plant---and Euphorbia esula L is a raw material; Utilize the active insecticidal components in the former plant to carry out control of insect; Process a kind of environment friendly agricultural insecticide through science is composite, its main active insecticidal components is a flavonoid glycoside, reaches the purpose that suppresses insect through food refusal, stomach poison function.The present invention is mainly used in control matrimony vine aphid, and integrated control effect can reach more than 90%.
Euphorbia esula L plant insecticide aqueous emulsion technical advantage of the present invention is:
1 Euphorbia esula L plant insecticide aqueous emulsion good water solubility of the present invention has insecticidal action preferably to the matrimony vine aphid.Virulence test shows that the lethality to insect can reach 90%.
Each component synergy among 2 the present invention, it is very inviolent to have toxic action, and insecticidal activity is remarkable, after the dispenser, is prone to degraded, and low toxicity is to the 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 infusion process is adopted in test, and blade and aphid are dipped in the medicament, observes the aphid mortality then, and calculates lethality, and the result sees 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, No. 1, the peaceful Qi of life in 2 years, 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 handled.Take the dispenser of foliar spray method at 1 instar larvae initial stage of origination, evenly to squirt leave dual sides degree of being.Respectively before dispenser, 1d, 3d, 5d, 7d behind the medicine, 7d, 14d investigate 6 times altogether behind the secondary medicine.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 the better prevention effect to the matrimony vine aphid, and the 3d preventive effect is the highest behind the medicine, and preventive effect reaches more than 90%.
