Abstract
The invention relates to a pesticide composition containing schizonepeta and tobacco extracts, a preparation method and application thereof, and belongs to the field of pesticides. The invention aims to solve the technical problem of providing a pesticide composition containing schizonepeta and tobacco extracts, a preparation method and application thereof. The active ingredients of the pesticide composition containing the schizonepeta and the tobacco extract are extracted from the following raw medicinal materials in parts by weight: 1 part of schizonepeta and 0.5-6 parts of tobacco; the active ingredients can be prepared by mixing and extracting the raw medicinal materials of schizonepeta and tobacco together; or extracting herba Schizonepetae separately to obtain herba Schizonepetae extract, extracting tobacco separately to obtain tobacco extract, and mixing the two extracts. The pesticide composition containing the schizonepeta and the tobacco extract can well kill homoptera and hemiptera pests, such as scale insects, aphids, trialeurodes vaporariorum, lygus lucorum and the like, and has positive significance for agricultural production.
Description
Technical field
The present invention relates to the composition pesticide containing schizonepeta and tobacco extract and preparation method and application, belong to pesticide field.
Background technology
Schizonepeta original name " false Soviet Union ", popular name " ginger mustard " is labiate.Enter medicinal its dry cauline leaf and Hua Sui.Fresh and tender bud children's is calm best, balm leaf yellow green, stem side shaped microstrip purple, cross section yellow-white, the slightly black purple yellow green of tassel.Taste is put down, and warm in nature, nontoxic, faint scent is dense.Schizonepeta is sweating, alexipyretic, is one of conventional herbal medicine of China, can town phlegm, dispel the wind, cool blood, control influenza, the sweating of headache fever and chills, vomiting.
Tobacco is the herbaceous plant of Solanaceae, and about more than 60 plant, and major part distribution is beautiful in continent, minority is distributed in Oceania, and what China's introducing was cultivated has several, wherein cultivates the widest with tobacco N.tabacum L., can cigarette processed and pipe tobacco, leaf, containing nicotine, has infringement to the health of human body.The detritus of stem and leaf can be insecticide.Annual or perennial plant, often has cement pubescence; Leaf alternate, Dan Ye; Floral white, yellow, pale green or lavender, line up the raw panicle in top or lopsided raceme; Calyx tubulose is bell, and 5 split, and fruit often place is deposited and slightly increases, and not exclusively or completely surrounds fruit; Corolla tubular, funnel-form or high pin disk like, pipe range, eaves 5 splits; Stamen 5, and is born in below in the middle part of tube, flower pesticide lobe; Flowerpot ring-type; Ovary 2 Room, the column cap that style tool 2 splits; Fruit is a capsule, and 2 split to middle part or nearly base portion; Seed is small, most.

As can be seen from Table 8, product of the present invention has good preventive effect to cottonycushion scale, and better, visible than the control efficiency of single Herba Schizonepetae extract and tobacco extract, has synergistic function between product compositions of the present invention.And the preventive effect of the product adopting common extracting method to make is apparently higher than extracting separately rear blended product, visible common extraction contributes to improving dissolution rate, raising insecticide efficiency.In addition, have no during dispenser and have poisoning to show to crop.
Test example 4 the present invention contains the efficiency test of the composition pesticide grape green plant bug of schizonepeta and tobacco extract
Product J Y-01 of the present invention ~ JY-12 is used for preventing and treating grape green plant bug.This test 12 medicaments, 2 single doses, 1 blank, repeats for three times, Gong45Ge community.Minizone and surrounding all leave isolation strip, plot area 10m
2, community respectively processes randomized arrangement.
Be 50ppm by reagent agent thin up to activity component concentration, spray application to plant blade face, so that water membrane to appear in blade face, not lower of liquid is advisable.
Be fixed the green plant bug quantity statistics alive of blade before the test and listing mark.Within 5 days after dispenser, investigate and record the green plant bug number alive on each blade.Calculate Revision insect recluced rate and preventive effect, calculate and adopt following formula:
Ta: the individual amount of survival after treatment region control; Tb: the individual amount of survival before treatment region control
Ca: the individual amount of survival after the control of check plot; Cb: the individual amount of survival before the control of check plot
Each group is repeated meter of averaging, and calculate Revision insect recluced rate and preventive effect, its result is as shown in table 9.
