Embodiment 1

[0024] Example 1: Determination of the antibacterial activity of azoxystrobin and mancozeb compounded against P. infestans

[0025] The inhibitory effect of the combination of azoxystrobin and mancozeb on P. infestans was determined indoors by the toxic medium method, and compared with the control effect of azoxystrobin and mancozeb alone.

[0026] Test method: Add quantitative agents to PDA medium, inoculate P. infestans infestans after cooling, and test the results after cultivating at 24°C for 4 days without light. The test results are shown in Table 2.

[0027] Table 2 Comparison table of antibacterial activity assay results against potato infestans

[0028]

[0029] It can be seen from Table 2 that the combination of azoxystrobin and mancozeb has good indoor antibacterial activity against P. infestans, which is higher than that of a single agent.

Embodiment 2

[0030] Embodiment 2: 70% azoxystrobin · zinc zinc wettable powder, the efficacy test of preventing and treating apple spotted leaf disease

[0031] Its formula consists of, including the following components by weight:

[0032] Azoxystrobin 5%

[0033] Zinc 65%

[0034] Sodium dodecylbenzenesulfonate 2%

[0035] Silica 10%

[0036] Lignocalcium 4%

[0037] Pull apart powder 3%

[0038] K12 3%

[0039] Light calcium carbonate balance

[0040] The above-mentioned original drug, various auxiliary agents and fillers are fully mixed according to the formula ratio, and after being pulverized by an ultra-fine pulverizer, a 70% azoxystrobin-zinc wettable powder can be obtained.

[0041] Test method: when the apple trees first appeared lesions, spray azoxystrobin, zineb and the above-mentioned compound mixture respectively, and use clear water as a control, spray the medicine for 3 times in total, and the interval between the two treatments is 7 days, The survey results 15 days...

Embodiment 3

[0045] Embodiment 3: 40% azoxystrobin · thiram double suspension concentrate, the efficacy test of preventing and treating peanut leaf spot

[0046] Its formula consists of, including the following components by weight:

[0047] Azoxystrobin 4%

[0048] Phiram 36%

[0049]Sodium methylnaphthalenesulfonate formaldehyde condensate 5.5%

[0050] Silica 5%

[0051] Magnesium Aluminum Silicate 2%

[0052] Ethylene glycol 10%

[0053] Tributyl Phosphate 0.1%

[0054] Diatomaceous earth 5%

[0055] water balance

[0056] Add the above-mentioned original medicine, various auxiliary agents and fillers into a sand mill according to the proportion of the formula, and grind to make a 40% azoxystrobin · thiram double suspension.

[0057] The control effects of azoxystrobin, thiram and the above-mentioned compound mixtures on peanut leaf spot were measured in the field, and water was used as a control. The pesticide was sprayed when the disease spots first appeared in the peanut fi...

Abstract

The invention belongs to the technical field of agricultural fungicides, in particular to a bactericidal composition containing azoxystrobin and a thiocarbamate fungicide and an application thereof. The azoxystrobin and the thiocarbamate fungicide are adopted for complexing, the thiocarbamate fungicide is any one of mancozeb, zineb, maneb or thiram, and the two can represent excellent synergy within a certain mix proportion range by complexing; compared with a single medicament, the bactericidal composition can significantly improve the bactericidal effect, expand the bactericidal spectrum, effectively avoid the possible problems of drug resistance, reduced efficacy and the like due to the use of the single medicament of the azoxystrobi and prolong the life cycle and the service life of the single medicament.

Description

technical field [0001] The invention belongs to the technical field of agricultural fungicides, and in particular relates to a fungicidal composition compounded with azoxystrobin and thiocarbamate fungicides and its application. Background technique [0002] Azoxystrobin (Azoxystrobin) is a new type of high-efficiency methoxyacrylate fungicide, which has protection, treatment, eradication, penetration and systemic activities. It destroys the energy synthesis of bacteria by inhibiting the respiration of bacteria and loses their vitality. Azoxystrobin has a broad-spectrum fungicidal activity against almost all fungal diseases (Ascomycetes, Basidiomycetes, Oomycetes and Deuteromycetes) diseases such as powdery mildew, rust, scab, net spot, downy mildew It has good activity on dozens of diseases such as rice blast and rice blast, and is suitable for various crops such as grains, vegetables, rice, fruit trees and economic crops, and has good crop safety and very outstanding envir...
