example 1

[0017] Bioassay Example 1: Toxicity determination of pyrithrimol or pyrithrimol sulfonate combined with triazole fungicides against cucumber powdery mildew

[0018] Test object: Cucumber powdery mildew pathogen

[0019] The test refers to "Pesticide Bioassay Technology" (Edited by Chen Nianchun, published by Beijing Agricultural University Press), and "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006" This test uses the cucumber powdery mildew pot test method. On the basis of the preliminary test, select 2 melon seedlings at the true leaf stage with the same growth, write the label number with an oily marker, insert it into the pot of cucumber seedlings, discharge them in sequence, and spray the medicine on the melons by spraying the leaves. On the leaves of seedlings, after spraying treatment, dry the test materials in the fume hood or greenhouse for 24 hours before inoculation. Cultivate in the greenhouse for 7 days to investigate the control effect, the grading st...

[0024] Bioassay Example 2: Toxicity determination of pyrithrimol or pyrithrimol sulfonate combined with triazole fungicides against wheat powdery mildew

[0025] Test object: Wheat powdery mildew

[0026] The test refers to "Bioassay Technology of Pesticides" (Edited by Chen Nianchun, published by Beijing Agricultural University Press), and "Guidelines for Indoor Bioassay Tests of Pesticides NY / T1156.2-2006". On the basis of the preliminary experiment, select wheat seedlings at the 3-leaf stage with the same growth, write the label number with an oily marker, insert them into potted wheat seedling pots, and discharge them in sequence. On the leaves of seedlings, after spraying treatment, dry the test materials in the fume hood or greenhouse for 24 hours before inoculation. Cultivate in the greenhouse for 7 days to investigate the control effect, the grading standard implements the national standard of the People's Republic of China "Pesticide Field Efficacy Test Guidelines (1...

Embodiment 1

[0047] Example 1: 51% pyridylsulfonate · difenoconazole suspension concentrate

[0048] Ethyrimol Sulfonate 50%

[0049] Difenoconazole 1%

[0050] Sodium methylnaphthalenesulfonate formaldehyde condensate 10%

[0051] Xanthan Gum 1%

[0052] Bentonite 1%

[0053] Glycerol 1%

[0054]Water Make up to 100%.

[0055] The active ingredient, dispersant, wetting agent and water are mixed uniformly according to the ratio of the formula, and after grinding and / or high-speed shearing, a 51% pyridylsulfonate·difenoconazole suspension concentrate is obtained .

[0056] This embodiment is applied to the control of cucumber powdery mildew. Dilute 51% pyridilsulfonate·difenoconazole suspensible concentrate 2500 times with water and spray, and the control effects are 94.5% and 90.2% 7 days and 15 days after application. 50% pyrimifene sulfonate suspension was used by 2000 times and 5% difenoconazole suspension by 1000 times, and used in the same way, the control effects of 7 days an...

Abstract

The invention relates to a sterilization composition which comprises the effective gradients of ethirimol or bupirimate and triazole fungicide, wherein the mass ratio of the ethirimol or bupirimate to the triazole fungicide is 50: 1-1: 50, and the preferable mass ratio is 20: 1-1: 20. The invention has remarkable synergic effect after the ethirimol or the bupirimate and the triazole fungicide are compounded, and is used for preventing and treating diseases, in particular to fungous diseases of crops, such as fruit trees, cottons, rice, vegetables, and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing pyrithrimol or pyrithrimol sulfonate and triazole fungicides. Background technique [0002] In recent years, due to single and unscientific drug use, many diseases have become resistant to the currently used pesticides, such as cucumber powdery mildew, wheat powdery mildew, grape powdery mildew, banana leaf spot, etc. problem. At the same time, frequent application of pesticides has caused increased burden on farmers and increased environmental pollution. Therefore, there is an urgent need for new varieties of fungicides with high efficiency, low toxicity and environmental protection. [0003] Pyrimol or pyrithrimol sulfonate is an adenine nucleosine deaminase inhibitor, a systemic fungicide, and has protective and therapeutic effects. It can be quickly absorbed by plant roots, stems, and leaves, and circulates to various parts of the plant bo...
