Embodiment 1

[0029] Example 1, Indoor Toxicity Determination of ZJ5337 Compounded with Triazole Fungicides against Cucumber Powdery Mildew

[0030] Cucumber powdery mildew (Sphaerotheca uliginea) test method refers to the spore suspension inoculation method in the Agricultural Industry Standard of the People's Republic of China NY / T1156.11-2008. Select cucumber seedlings with consistent growth and dry in the shade for 24 hours after spraying. Wash the fresh spores on the cucumber leaves covered with powdery mildew, filter with double-layer gauze, make a suspension with a spore concentration of about 100,000 / ml, and spray to inoculate. After inoculation, the test materials were air-dried naturally, and then moved to a constant temperature room under the light (21-23°C). After 7-8 days, a graded investigation was carried out according to the incidence of the blank control, and the control effect was calculated by the disease index. Through the linear regression analysis between the control ...

Embodiment 2

[0045] Example 2, Indoor toxicity determination of ZJ5337 and triazole fungicides against banana leaf spot, apple spotted leaf spot, and grape anthracnose

[0046] Test objects: Banana leaf spot (Cordana musae) and grape anthracnose (Colletortrichum gloeosporiodes) were preserved in the strain room of this laboratory; apple spot leaf spot (Alternaria mali) was collected from Hebei and separated and purified by our laboratory.

[0047] Test method: refer to the mycelium growth rate method in "Agricultural Industry Standard of the People's Republic of China NY / T1156.2-2006". Each agent is treated with 5 doses according to the content of active ingredients, and the above-mentioned pathogenic bacteria are cultivated with PDA medium. The bacteria block was moved to the center of the pre-prepared toxic PDA medium, and then cultured in a 25°C incubator, and each treatment was repeated 4 times. Depending on the growth of the CK colony, use the cross method to measure the colony diame...

Embodiment 3

[0067] Example 3: 80% ZJ5337 flusilazole water dispersible granules

[0068] Weigh 40% ZJ5337, 40% flusilazole, 4% TERSPERSE2700, 2% diffusing agent NNO, 2% pull open powder BX, 1% K-12, 3% corn starch, 3% ammonium sulfate, attapulgite to 100% parts by mass. 80% ZJ5337·flusilazole water dispersible granules are prepared by the conventional method of preparing water dispersible granules from the above raw materials, that is, mixing, ultrafine airflow pulverization and granulation.

Abstract

The invention provides a sterilization composition containing ZJ5337 and a triazole bactericide. The triazole bactericide is one of or a combination comprising two or more of tebuconazole, difenoconazole, flusilazole and myclobutanil, and a mass ratio of the ZJ5337 to the triazole bactericide is 20:1-1:20. The sterilization composition has the advantages of good sterilization effect and difficult generation of the drug resistance, and is especially suitable for controlling cucurbits powdery mildew, banana leaf spot disease, apple altermaria leaf spot, pear scab and bittle rot of grape.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, in particular to a fungicidal composition for preventing and treating various diseases on vegetables and fruit trees. Background technique [0002] Melon powdery mildew, banana leaf spot, apple spot defoliation, pear scab and grape anthracnose are common diseases on vegetables and fruit trees. When serious, they can cause a large reduction in yield, seriously endangering yield and quality . In the actual process of agricultural production, the most likely problem in disease prevention and control is the emergence of bacterial resistance. Tebuconazole, difenoconazole, flusilazole, and myclobutanil are triazole fungicide varieties. Pathogens develop resistance to them very quickly, and the amount of drug used alone is increasing, and the amount of drug can inhibit crops grow. If the medicine is used for more than three times in a row, it is very likely to cause phytotoxicity such as smaller...
