Description
Technical field
The present invention relates to pesticides application technical field, and in particular to a kind of bactericidal composition, for preventing and treating watermelon anthrax.
Background technology
Watermelon, annual liana of overgrowing is the fruit of summer, and pulp taste sweet tea can cool and drive away summer heat；Seed oil-containing, can make to disappear
Send food；Pericarp is medicinal, there is heat-clearing, diuresis, the effect of hypotensive.China is the watermelon place of production maximum in the world.Watermelon anthrax
It is the important disease in watermelon production, main harm blade can also endanger vines, petiole and fruit.Within whole growth period
Can occur, but it is most heavy with the generation of plant strain growth intermediary and later stages, cause withered, fruit rot of falling leaves.At present about the research of anthracnose
Report is less, and the preventing and treating of anthracnose relies primarily on the medicaments such as benzimidazole medicament carbendazim and thiophanate methyl in production, but
The long-term use of single medicament is easy to make germ develop immunity to drugs.Therefore, the active ingredient for screening the different mechanisms of action is carried out
The preventing and treating compounded to anthracnose is significant.
Enestroburin (Enestroburin, SYP-Z071) is first methoxy acrylic sterilization of domestic-developed
Agent, is developed for 1997 by Shenyang Chemical Engineering Inst.With wide sterilization spectrum, bactericidal activity is high, and powdery mildew and downy mildew can be prevented and treated simultaneously
The medicament of epidemic disease.Also there is extraordinary preventive effect to scab, anthracnose, spot defoliation etc..Toxicity is low, it is good to have to environment
Good compatibility.
Eugenol (Eugenol), chemical name：2- methoxyl group -4- chavicols, are plant clove of myrtaceae
The main component of volatile oil in the dry flower of (Eugeniacaryophyllata Thunb).Eugenol is colourless or pale yellow
Liquid, there is strong cloves fragrance, water insoluble, is mainly used in antibacterial, hypotensive etc..
The research for being applied to watermelon anthrax as the composition of active ingredient using eugenol, Enestroburin at present not yet has phase
Close report.

Embodiment
Technical scheme and technique effect are described further below in conjunction with specific embodiment, institute of the present invention
The percentage stated is weight percentage.
Implementation of an application example one：Eugenol, Enestroburin and its compounding are to watermelon anthrax Toxicity Determination
After determining the effective inhibition concentration scope of each medicament through prerun, each medicament is set 5 agent by active constituent content respectively
Gradient processing is measured, if clear water is compareed.Reference《Farm-chemical indoor determination test rule bactericide》Carry out, using mycelial growth speed
Rate method determines virulence of the medicament to watermelon anthrax.Colony diameter is measured with crossing method after 72h, the net growth of each processing is calculated
Amount, mycelial growth inhibition rate.
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm value (x), with minimum
Square law tries to achieve virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value.Simultaneously according to the abundant methods of Sun Yun
Co-toxicity coefficient method (CTC) evaluate the synergistic effect of pharmacy mix, i.e. CTC≤80, composition shows as antagonism, when 80
<CTC<120, composition shows as summation action, and when CTC >=120, composition shows as synergistic effect.Result of the test such as table 1.
