Abstract
The invention relates to a bactericide containing thifluzamide and radix astragali. The bactericide comprises effective components of thifluzamide and radix astragali, the weight ratio of which is 1-6:10-50. The invention further claims protection of an application of the bactericide to prevent and cure sheath blight of paddy rice. The bactericide is mixed by a traditional Chinese medicine of radix astragali and the bactericide component, and it is proved through a test that after radix astragali is added in the bactericide component, the drug resistance of the bactericide to a pathogen is changed, thereby improving the prevention and curing effect of the bactericide, and greatly reducing drug cost and drug residues. The bactericide creates great economical benefit for a farmer, and ensures food security.
Description
Technical field
The present invention relates to technical field of pesticide, specifically a kind of bactericide containing thifluzamide and the Radix Astragali.
Background technology
Thifluzamide, Chinese another name: thifluzamide; 2 ', 6 '-two bromo-2-methyl-4 '-trifluoromethoxy-4-Trifluoromethyl-1,3-thiadiazoles-5-hydroxyl anilide; Thiophene fluorine bacterium amine; Thifluzamide/2 ', 6 '-two bromo-2-methyl-4 '-trifluoromethoxy-4-Trifluoromethyl-1,3-thiadiazoles-5-hydroxyl anilide.Thifluzamide is succinate dehydrogenase inhibitor, suppresses succinic acid dehydrogenase in germ tricarbonic acid cycle, causes thalline dead.It has very strong Uptake and translocation performance, can the mode such as foliar spray, seed treatment, soil treatment use.Thifluzamide all has good control efficiency to many kinds of fungal diseases, can be widely used in the various crop such as water paddy and wheat class, peanut, cotton, beet, coffee, potato, lawn.Production is mainly used in the banded sclerotial blight of preventing and treating paddy rice and wheat class.In recent years due to its large-area popularization, pathogen is caused to reduce its susceptibility, resistance grow.
Summary of the invention
The technical problem to be solved in the present invention is, for the deficiency that above-mentioned existing bactericide exists, a kind of bactericide containing thifluzamide and the Radix Astragali is provided, overcome that existing bactericide causes due to resistance problems preventive effect reduces, consumption strengthens, residual high and defect that cost is high.
The present invention realizes the technical scheme that above-mentioned purpose takes: a kind of bactericide containing thifluzamide and the Radix Astragali, active ingredient is made up of thifluzamide and the Radix Astragali, and the described Radix Astragali and the weight ratio of thifluzamide are 1-6: 10-50.
The present invention's also application of claimed described bactericide on the water prevention rice sheath blight.
The present invention utilizes Chinese herbal medicine astragalus and microbiocidal composition mixture, test proves, add the Radix Astragali in germicide constituent after, the pesticide resistance of pathogen to bactericide can be reversed, thus improve the control efficiency of bactericide, and can significantly reduce drug cost and medicament residue, for peasant household creates higher economic benefit, also ensure that food security simultaneously.
Embodiment
Below in conjunction with test data and embodiment, technical scheme of the present invention and beneficial effect are described further.
One indoor joint toxicity measuring test
For clear and definite bactericide (propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, own azoles alcohol, jinggangmeisu, Difenoconazole) and Radix Astragali mixture affect the virulence of Rhizoctonia solani Kuhn, mycelial growth rate method is adopted to carry out indoor measurement.
Rhizoctonia solani Kuhn is separated from surrounding area, Guigang, purifying cultivate after through Koch's Postulates verify its pathogenic after by strain inoculation in PDA medium, at 25 DEG C, under 90% damp condition, cultivate 5d, break into bacterium cake with 0.4cm card punch after mycelia covers with culture dish and use.
The Radix Astragali and bactericide are pressed active ingredient part by weight 1: 10 respectively, 1: 20, 1: 50, 3: 10, 6: 10, 6: 30, 6: 50 mixing are made into binary built agent as mixture 1-mixture 7, bactericide single dose and mixture 1-mixture 7 are respectively diluted 7 concentration according to geometric ratio gradient from 10ppm, blank is made with clear water process, make PDA flat board, arranging without medicament is contrast, every concentration repeats 3 times, after aseptically the bacterium cake accomplished fluently being inverted in the dull and stereotyped central authorities of each process PDA, flat board is placed in 25 DEG C, cultivate under 90% damp condition, investigation result when mycelial growth diameter reaches culture dish diameter about 50%, calculate inhibiting rate, and the EC of each chemicals treatment is calculated by DPS Software of Data Statistics
50and composite co-toxicity coefficient.Because Radix Astragali single dose does not almost affect for Rhizoctonia solani Kuhn, therefore the present invention calculate composite co-toxicity coefficient time by the EC of Radix Astragali single dose
50be designated as 0, the EC of co-toxicity coefficient=composite
50the EC of/bactericide single dose
50.Statistics is as shown in the table.
As can be known from the above table: the Radix Astragali and propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, own azoles alcohol all have obvious synergistic effect to Rhizoctonia solani Kuhn afterwards in 1-6: 10-50 ratio is composite, and the Radix Astragali and jinggangmeisu, Difenoconazole be added or inhibitory action in composite rear to show Rhizoctonia solani Kuhn of 1-6: 10-50 ratio.
Two field medicine effect tests
Test medicine
12 single doses: propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, own azoles alcohol, jinggangmeisu, Difenoconazole;
12 mixed agents: be the weight ratio of 6: 50 according to the Radix Astragali and bactericide, add the water extract of the Radix Astragali in above-mentioned single dose.
Test establishes 31 process altogether together with blank, and each process repeats for 3 times, Gong93Ge community, each community randomized arrangement.
Test method
By above-mentioned single dose and mixed agent even spraying, 21 days investigation rice sheath blight disease controlling results after medicine.
Result of the test
| Bactericide | Single dose preventive effect (%) | The Radix Astragali and bactericide are 6: 50 mixtures (%) |
| Propiconazole | 64.55 | 89.60 |
| SYP-3375 | 65.56 | 85.17 |
| Carbendazim | 46.81 | 90.98 |
| Epoxiconazole | 64.02 | 87.89 |
| Prochloraz | 70.40 | 86.23 |
| Fluoxastrobin | 66.82 | 90.63 |
| Thifluzamide | 72.63 | 86.91 |
| Tetraconazole | 64.62 | 85.55 |
| Tebuconazole | 72.22 | 88.20 |
| Own azoles alcohol | 71.03 | 88.54 |
| Jinggangmeisu | 52.41 | 51.24 |
| Difenoconazole | 64.38 | 70.24 |
As can be known from the above table: the Radix Astragali and propiconazole, SYP-3375, carbendazim, epoxiconazole, prochloraz, Fluoxastrobin, thifluzamide, tetraconazole, Tebuconazole, own azoles alcohol are more obvious than single dose good in the composite rear preventive effect to rice sheath blight disease of 6: 50 ratio, and the Radix Astragali and jinggangmeisu, Difenoconazole are more or less the same in the composite rear preventive effect to rice sheath blight disease of 6: 50 ratio and single dose.
