Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains own azoles alcohol and kresoxim-methyl.
Technical background
Own azoles alcohol (hexaconazole) is the triazole bactericidal agent of Syngenta Co.,Ltd's exploitation.Molecular formula: C
14H
17Cl
2N
3O, chemical name: (RS)-2-(2,4 dichloro benzene base)-1-(1H-1,2,4-triazol-1-yl)-oneself-2-alcohol.
Own azoles alcohol belongs to sterol demethylation inhibitor, destroys and stop the biosynthesis of the cell membrane important composition composition ergosterol of germ, causes cell membrane not form, and makes germ death.Suction in the tool, protection and therapeutic activity.
Kresoxim-methyl (kresoxim-methyl) is the methoxy acrylic bactericide of BASF Aktiengesellschaft's exploitation.Molecular formula: C
18H
19NO
4, chemical name: methyl (E)-2-methoxyimino-2-[2-(0-toloxyl) phenyl] and acetate.
Kresoxim-methyl belongs to the mitochondrial respiratory inhibitor; it is a kind of wide-spectrum bactericide; and the lasting period is long; most of diseases that pathomycetes such as Ascomycetes, Basidiomycetes, Fungi Imperfecti and oomycetes subclass are caused have protection, treat and root out activity; to crop, people, animal and beneficial organism safety, pollution-free substantially to environment, but the intrinsic pesticide resistance of this series bactericidal agent is high-caliber; be easy to generate pesticide resistance, and the cost height.
No matter be own azoles alcohol, kresoxim-methyl or other efficient germicides, long-term use separately makes disease develop immunity to drugs easily, causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.The active ingredient of the different mechanisms of action is carried out composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.Own azoles alcohol is different with the kresoxim-methyl mechanism of action, and mutual composite have good synergistic effect within the specific limits.And composite about own azoles alcohol and kresoxim-methyl do not see relevant report at present at home and abroad as yet.

Embodiment
To further instruction of the present invention, the percentage among the embodiment all is weight percentage below in conjunction with embodiment, but the present invention is not limited thereto.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.
Implementation of an application example one: own azoles alcohol is composite to the rice blast Toxicity Determination with kresoxim-methyl
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
After the effective inhibition concentration scope of each medicament was determined in prerun, each medicament was established 5 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament rice blast.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively the pure and mild kresoxim-methyl of own azoles shared ratio in combination
A is own azoles alcohol
B is a kresoxim-methyl
Result of the test is as shown in table 1:
The own azoles alcohol of table 1, kresoxim-methyl and composite toxicity test analysis of results table thereof to rice blast
As shown in Table 1, own azoles alcohol, kresoxim-methyl are to the EC of rice blast
50Be respectively 2.15mg/L and 16.43mg/L.The virulence of own azoles alcohol is higher than the virulence of kresoxim-methyl.Illustrate that pure being mixed in the scope at 32: 1～1: 64 with kresoxim-methyl of own azoles all shows obvious synergistic effect, wherein working as own azoles alcohol was obvious with the kresoxim-methyl weight ratio in the scope at 8: 1～1: 16.
