Embodiment 1

[0023] Example 1: Indoor toxicity test of indazolesulphamide pyramethazone to Phytophthora infestans (Phytophthprainfestans)

[0024] The test object is the potato late blight pathogen Phytophthprainfestans collected from the field. The method refers to the "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", the mycelium growth plate method.

[0025] Table 1. Indoor toxicity test results of indazolesulfin-pyramid to Phytophthora infestans (Phytophthprainfestans)

[0026]

[0027] It can be seen from Table 1 that the mixing ratio of indazolesulfame and pyrazastrobin between 20:1 and 1:20 has obvious synergistic effect on Phytophthprainfestans, and the co-toxicity coefficients are all above 160 .

Embodiment 2

[0028] Example 2: Indoor toxicity determination test of indazolesulfin-pyramid to Pseudoperonosporacubensis.

[0029] The test object is the cucumber downy mildew pathogen Pseudoperonosporacubensis collected from the field, and the method refers to the "People's Republic of China Agricultural Industry Standard NY / T1156.3-2006", the plate leaf method.

[0030] Table 2. Indoor toxicity test results of indazolesulfin and pyrazastrobin against Cuban pseudoperonosporacubensis (Pseudoperonosporacubensis)

[0031]

[0032] It can be seen from Table 2 that the mixture of indazolesulfin and pyramethazone at a ratio of 20:1 to 1:20 has obvious synergistic effects on Pseudoperonosporacubensis, and the co-toxicity coefficients are all above 170 .

Embodiment 3

[0033] Example 3: Indoor toxicity determination test of indazolesulfin-pyramid to Plasmoparaviticola.

[0034] The test object is Plasmoparaviticola, the pathogen of grape downy mildew collected from the field, and the pot test method was used.

[0035] Table 3. Indoor toxicity test results of indazolesulfin-pyramid to Plasmoparaviticola

[0036]

[0037] It can be seen from Table 3 that the mixing ratio of indazolesulfame and pyramethastrobin between 20:1 and 1:20 has obvious synergistic effect on Plasmoparaviticola, and the co-toxicity coefficients are all 150 above.

[0038] The present invention will be further described below in conjunction with implementation examples.

Abstract

The invention discloses a sterilization composition containing amisulbrom and ametoctradin. According to the sterilization composition, amisulbrom and ametoctradin are taken as the active ingredients, and weight ratio of amisulbrom to ametoctradin ranges from 20:1 to 1:20; the total weight of amisulbrom and ametoctradin accounts for 5 to 80% of the weight of the sterilization composition; the sterilization composition can be prepared into one agent selected from a suspending agent, a dispersible oil suspended agent, a water dispersible granule, and a wettable powder, is used for preventing and treating crop diseases caused by fungal pathogens, and especially crop downy mildew and phytophthora disease caused by peronospora pathogens. Application amount of the sterilization composition is reduced, spraying times are reduced, application cost is reduced, and the sterilization composition is safe for crops.

Description

technical field [0001] The present invention relates to a bactericidal composition, which uses indazole sulfastrobin and pyramethazone as active ingredients, and is suitable for preventing and treating crop diseases caused by pathogenic fungi and bacteria, especially those caused by pathogens of Peronosporales (Peronosporales). Crop downy mildew, blight, etc. Background technique [0002] Amisulbrom (amisulbrom) is a triazole sulfonamide fungicide, which is effective against oomycetes and proteobacteria, especially for zoospores, and is mainly used to prevent and control crop diseases caused by oomycetes, such as grape frost Mildew, potato late blight, etc., resistant to rain erosion, strong persistence. [0003] Ametoctradin is a triazole-pyrimidine fungicide, which is a mitochondrial respiration inhibitor. Zoospore formation, release and germination, extremely high residual activity and resistance to rain. [0004] pyraclostrobin is a systemic fungicide with excellent p...
