Additives and excipients can be added in the active components to produce wettable powder, water dispersible granule, suspending agent, microemulsion and aqueous emulsion which are used to control diseased caused by ascomycetous, basidiomycetous and adelomycete pathogenic fungi.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on crop pest that contains Flusilazole and phonetic mould amine.
Technical background
Flusilazole (flusilazole) is the miazines bactericide.Molecular formula is C
16H
15F
2N
3Si, chemical name: two (4-fluorophenyl) methyl (1H-1,2, the support of 4-triazol-1-yl methylene) silane.
Flusilazole belongs to triazole bactericidal agent, and this medicine mainly is the biosynthesis that destroys and stop the cell membrane important composition composition ergosterol of germ, causes cell membrane not form, and makes germ death.In the antithetical phrase due to the germ of Gammaproteobacteria, Basidiomycetes and Fungi Imperfecti disease effective, invalid to oomycetes.
Phonetic mould amine (pyrimethanil) is that molecular formula is C by the anilino-pyrimidine series bactericidal agent of Bayer AG exploitation
12H
13N
3, chemical name is N-(4, a 6-dimethyl pyrimidine-2-yl) aniline.
Phonetic mould amine mechanism of action uniqueness promptly suppresses the pathogen protein secreting, comprises reducing some hydrolase levels, and tool infers that these enzymes and pathogen enter host plant and cause that the necrosis of parasitic main organizer is relevant.In having, phonetic mould amine colleague inhales conduction and fumigation action, the spray medicines such as flower, young fruit that reach plant after the dispenser rapidly position kill pathogens that is beyond one's reach, and drug effect is faster, more stable.
No matter be Flusilazole, phonetic mould amine 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.Flusilazole is different with the phonetic mould amine mechanism of action, and mutually composite have good synergistic effect within the specific limits.And composite about Flusilazole and phonetic mould amine do not see relevant report at present at home and abroad as yet.

Implementation of an application example two: Flusilazole and Pyrimethanil compositional are to the botrytis cinerea pers Toxicity Determination
Test medicine provides by Shaanxi means of agricultural production trade 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 botrytis cinerea pers.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 Flusilazole and phonetic mould amine shared ratio in combination
A is a Flusilazole
B is phonetic mould amine
Result of the test is as shown in table 1:
Table 1 Flusilazole, phonetic mould amine and composite toxicity test analysis of results table thereof to botrytis cinerea pers
As shown in Table 1, Flusilazole, phonetic mould amine are to the EC of botrytis cinerea pers
50Be respectively 1.02mg/L and 55.17mg/L.The virulence of Flusilazole is higher than the virulence of phonetic mould amine.Flusilazole and 1: 1,1: 5,1: 10,1: 15,1: 20 synergy ratio of phonetic mould amine proportioning are respectively 1.62,1.82,2.13,1.86,1.58, illustrating that Flusilazole and phonetic mould amine were mixed in the scope at 1: 1 to 1: 20 all shows obvious synergistic effect, synergy ratio SR maximum when Flusilazole and phonetic mould amine weight ratio are 1: 10 wherein, synergistic effect is the most obvious.
