Description
Technical field
The present invention relates to a kind of control of plant disease medicine, further relates to a kind of plant antibacterial.
Background technology
2- amino -5- sulfydryl -1,3,4- thiadiazoles zinc (Chinese name zinc thiazole) are a kind of plant antibacterial, are widely used in
The preventing and treating of the plant diseases such as bacterial blight of rice, but through research discovery, zinc thiazole or a kind of thyroid interferent, Neng Gouyin
The parathyroid tissue hypertrophy of laboratory animal is played, and finds that its toxicity has obvious dosage effect dependency under study for action.As
A kind of pesticide, can have undesirable effect to the health of user, and will also result in pollution in the environment.Therefore its poison how is reduced
Property, or in the case where prevention effect is not affected, its consumption is reduced, become problem demanding prompt solution in prior art.
The content of the invention
To solve aforementioned technical problem, technical scheme below is present invention employs：There is provided control of plant disease medicine, its
It is characterized in that described compositionss are 1 by least one adjuvant suitable for control of plant disease medicine and mass ratio:0.07~0.9
2- amino -5- sulfydryl -1,3,4- thiadiazoles zinc (common first names zinc thiazole, abbreviation compound (I)) and 4- methyl isophthalic acids, 2,3- thiophenes two
Azoles -5- formic acid Beta Naphthol 99MIN esters (abbreviation compound (II)) is constituted.The chemical formula of the compound (II) is as follows：
Described control of plant disease medicine, the dosage form that it is characterized in that the bactericide is selected from emulsifiable concentrate, wettability
One kind in powder, dry suspension, soluble powder.Preferably dry suspension, the gross mass of compound (I) and compound (II)
Account for the 15%~30% of the control of plant disease medicine gross mass.When the control of plant disease medicine is dry suspension, institute
State the adjuvant for dry suspension to be made up of the filler of dispersant, wetting agent, disintegrating agent, binding agent, defoamer, water and surplus,
One or more of the disintegrating agent in Sodium Chloride, sulfate, carbonate and sodium carboxymethyl cellulose.
The dispersant is selected from sodium lignin sulfonate, calcium lignosulfonate, polycarboxylate, alkylphenol polyoxyethylene formaldehyde
A kind of described froth breaking in condensation substance, fatty alcohol polyoxyethylene ether sulfate and alkylphenol polyoxyethylene succinate sulfonate
Agent is selected from the fatty acid ester compounded thing of higher alcohols, the representative examples of saturated aliphatic carboxylic of C10~C20 and C10~C20 representative examples of saturated aliphatic carboxylic esters
In one or more.
The binding agent is selected from one or more in gelatin, arabic gum, polyvinyl alcohol, Polyethylene Glycol and starch.
The wetting agent includes sodium lauryl sulphate, dodecylbenzene sodium sulfonate, Negel, alkyl naphthalene sulfonic acid
One or more in sodium formaldehyde condensation substance and alkylphenol-polyethenoxy base ether.
Described filler is Kaolin, kieselguhr, bentonite, attapulgite, Pulvis Talci, starch, glucose, sulfur selected from filler
At least one in sour sodium, precipitated calcium carbonate.The water content of the compositionss is 0.2~0.5% (wt).
Under study for action it was found that working as zinc thiazole and 4- methyl isophthalic acids, 2,3- thiadiazoles -5- formic acid Beta Naphthol 99MIN ester (abbreviationizations
Compound (II)) composition when carrying out compatibility with special ratios, can significantly improve the bacteriostatic activity of zinc thiazole.To compound (II)
Acute toxicity detection shows its category low toxicity compounds, and the side effect of athyreosis interference.The plant disease that the present invention is provided is prevented
Control medicine, compound (II) itself to bacterial blight of rice prevention effect and it is unconspicuous in the case of, by preferred zinc thiazole
(I) with the ratio of compound (II), the bacteriostatic activity of compositionss is increased substantially so as to obtain a kind of new control of plant disease
Medicine.Usage amount of the zinc thiazole when being administered is substantially reduced, zinc thiazole is reduced to the pollution of environment and to user health
The harmful effect for causing.We have found especially that in an experiment, zinc thiazole and the preferred proportion of compound (II) that the present invention is provided
Raising to zinc thiazole antibacterial effect is the most obvious, and higher or lower compound (II) addition cannot all produce the effect.
Specific embodiment
The control of plant disease medicine that the present invention is provided, preparation becomes dry suspension, by compound (I), compound (II)
Constitute with least one adjuvant suitable for dry suspension.The formula of the compositionss is respectively as shown in embodiment 1~4 in following table
(percentage ratio shown in table is the mass percent for accounting for compositionss gross mass)：
The compound method of the compositionss is：
1) component respectively than water according to proportioning is added to into dosage bunker and adds water to pulpous state, stirred；
2) coarse pulverization is carried out using high-speed shearing machine, is crushed to granularity for 100~200 mesh；
3) adopt sand mill sand milling to granularity for 8000~10000 mesh after coarse pulverization；
4) pressure spray drying tower drying, pelletize are sent into after sand milling, the satisfactory particle diameter of water content is obtained for 80~100
The hollow perforate spherical particle of purpose.
The dispersant is selected from fatty alcohol polyoxyethylene ether sulfate, and wetting agent is selected from dodecylbenzene sodium sulfonate, disintegrate
Agent is selected from Sodium Chloride, and binding agent is selected from Polyethylene Glycol, and defoamer is selected from hexadecylic acid.
Prevention effect is tested
The compound (I) and compound (II) of bacterium method for measuring test different proportion are connect to the white leaf of Oryza sativa L. with field leaf-cutting
The prevention effect of rot, experimental procedure is as follows
1st, the rice leaf spot bacteria strain provided using Institute of Plant Protection of academy of agricultural sciences of Zhejiang Province, culture becomes 109The suspension of individual/ml
Afterwards, Oryza sativa L. 3~4cm of blade tip is deducted with the dissecting scissorss for being moistened with bacterium solution, 20 rice leaves of per group of selection are prevented in 7 days sprays after bacterium are connect
Control, 10 days prevention effects of the examination compared with matched group (prevention effect is calculated with Spot expansion) and using Excel pair after administration
Experimental result carries out t inspections
2nd, packet see the table below (means ± s, n=20) with administration and effect situation
By above-mentioned each group medicine, experimental group 1~4 and negative control 1 are by dry suspension obtained in each embodiment according to thiazole
Zinc final concentration 200ppm is diluted, and negative control 2 prepares compound (II) becomes 20% dry suspension, and is diluted to dense eventually
Degree 200ppm, positive controls are using the dry suspension for being added without active component, 1000 times of dilute.
Test result indicate that, the control of plant disease medicine that the present invention is provided, by preferred specific zinc thiazole and chemical combination
The ratio of thing (II), can significantly improve effect when zinc thiazole is prevented and treated for bacterial blight of rice.With using existing zinc thiazole
1 group of negative control compare, the prevention effect of each experimental group is significantly increased (P ＜ 0.05).Find in further experiment, it is single
When solely applying compound (II), to bacterial blight of rice substantially to no effect.And only when compound (II) and zinc thiazole are with this
When ratio in inventive technique scheme carries out proportioning, the prevention effect to bacterial blight of rice of zinc thiazole can be just significantly improved.
