Description
Technical field
The present invention relates to a kind of magnolol synergy fungicide for being used to prevent and treat ring spot, belong to agricultural and chemical field.
Background technology
Chemical pesticide is widely used, and huge effect has been played in terms of higher yield of crops and stable yields is ensured.But tradition
" 3R " problem caused by long-term a large amount of unreasonable uses of chemical pesticide, i.e. residual, resistance, wildness is on the rise again, causes
The common concern of society.The demand sought and develop the novel agrochemical to human health and ecological environment security is more and more urgent.
Compared with chemical pesticide, biological pesticide is typically considered to have nuisanceless, pollution-free, noresidue, is not likely to produce resistance etc. substantially
Advantage.
Ring spot is the ring spot Common Diseases such as apple, pears, jujube, beans, pawpaw, capsicum, grape, lettuce, is
Botryospuaeria berengeriana de Not.t.sp.Piricola (Nose) Kogonezawa et Sukuma bacterium
Conidium disperses, traveled near limb wound, hole skin and fruit hole skin, produce germ tube intrusion tree body, melon, fruits and vegetables,
Tealeaves, medicinal material limb and fruit are contaminated, serious threat Fruits production, and ring spot morbidity in recent years is in rising trend.It is universal at present
Prevented and treated using chemical bactericide, whole process repeatedly largely uses chemical agent, brings environmental pollution, thus is badly in need of finding one kind
Can effective sterilization and anticorrosion low-toxic agent.
Magnolol be sepia to the Magnolia cortex P.E of white fine powder, be Cortex Magnoliae Officinalis
Active ingredient in (Magnoliaofficinalis RehderetWilson) skin.Magnolol is to grampostive bacteria, acidproof
Property bacterium, filamentous fungi, streptococcus mutans have significant antibacterial activity, most strong to staphylococcic inhibitory action.The present application
Raw survey shows that magnolol has very to apple, pears, jujube, capsicum, grape ring spot etc. to people with field efficacy measurement result indoors
Good prevention effect.
Callicarpa nudiflora (Callicarpa nudiflora Hook.et Arn.) is Verenaceae Japanses beauty-berry platymiscium, mainly
Chemical composition has Phenylpropanoid Glycosides class, flavonoids, phenolic acid class, triterpenes, Diterpenes, iridoids and its glycoside and sterol etc..
100% callicarpa nudiflora decocting liquid is to staphylococcus aureus, staphylococcus albus, pseudomonas aeruginosa, typhoid bacillus, the double balls of meningitis
Bacterium, shigella dysenteriae, thermophilic oxygen bacterium, Escherichia coli, streptococcus, proteus are sensitive, also have convergence, desiccation in addition.
The present invention utilizes callicarpa nudiflora anti-inflammatory and astriction, and inventor's field efficacy result shows, callicarpa nudiflora to carry
Thing is taken to have good prevention effect to ring rot of apple etc..Echinacea is that uniquely have " marrow preservation " effect in nature, is shown
The material for improving and safeguarding autoimmune is write, Phenolic Compounds, polysaccharide are feverfew Echinacea Echinacea Purpurea
Cauline leaf, root extract, as immunomodulator and immunostimulant, have in antiviral, it is antimycotic, it is antitumor, and desinsection, disappear
Inflammation effect.Inventor's indoor biometricses result shows that Phenolic Compounds, polysaccharide can significantly improve beautyberry extract to apple wheel
The prevention effect of line disease, therefore Phenolic Compounds, polysaccharide are as callicarpa nudiflora synergist in the application.
The data-searching made according to inventor, at present magnolol be used as disinfectant use in agriculture and mainly have：Patent document

Depending on actual conditions.Reagent agent is diluted to the μ g/mL of final concentration 300, blade face conventional spray by active constituent content respectively；
80% carbendazol wettable powder (Jiangsu Soviet Union's Pesticides chemical plant), 1000 times of chemical drugs controls, blade face conventional spray, and set clear
Water compares.Spraying time is August 10 days, August 28 days, September 15 days, October 5, October 26, dispenser 5 times altogether.According to sky
White control incidence classification investigation.Fruit harvesting phase October 29, representative 1 plant of fruit tree, every plant of tree are selected per cell
By 5 points of East, West, South, North, interior thorax samplings, 50 fruits of every investigation, a fruit of coprocessing 750.Record morbidity fruit number, meter
Preventive effect is calculated, is shown in Table 1.Test data is analyzed with duncan's new multiple range method.
Preventive effect (%)=(blank district disease fruit number-treatment region disease fruit number)/blank district disease fruit number × 100
Prevention effect of the 1 different embodiments of table to Verticil-Veined Diseases of Apple Fruit
From table 1, the μ g/mL preventive effects of magnolol concentration of sterilant 300 prepared by the present invention are more than 80%, with medicament
The prevention effect of 1000 times of 80% carbendazol wettable powder is compareed without significant difference.Wettable powder is to apple in all formulations
The prevention effect of anthracnose is optimal, analyzes reason, it may be possible to the magnolol chemical composition complicated with beautyberry extract, simultaneously
Auxiliary material pair and two kinds of main components play synergy, and essence is the result mutually cooperateed between Multiple components.It is in addition, of the invention
Bactericide is applicable on ring spot disease crop non-target organism and environment-friendly.
