Problems solved by technology

[0012] Chloroxystrobin is a methoxyacrylate compound, and its main mechanism of action is to affect the respiration of bacteria. However, many studies have shown that this agent can make pathogenic bacteria resistant to drugs in a short period of time when used alone to prevent and control diseases. Lead to the failure of disease control; there are also many studies that show that wheat head blight is also prone to resistance to cyclostrobin
Clostristrobin and cyclostrobin used alone have a high risk of resistance, making them ineffective in the short term

Embodiment 1

[0036] Embodiment 1 (60% clostrostrobin · cyclostrobin suspension concentrate)

[0037] Raw material formula: by mass percentage

[0038]

[0039]

[0040] The preparation method is as follows:

[0041] According to the formula, weigh each component in proportion, put it into a ball mill and mill it for 30 minutes, filter, pump it into the dispersion tank for 3 minutes at high speed and then grind it fully with a sand mill to control the particle diameter of the solid component within 2 microns, and the grinding is completed Finally, stir evenly to obtain the suspension concentrate product.

Abstract

The present invention discloses a bactericidal composition containing 2-cyano-3-amino-3-ethyl phenylacrylate and clorine-nalidixic-methyl. Active constituents of the bactericidal composition are 2-cyano-3-amino-3-ethyl phenylacrylate and clorine-nalidixic-methyl. The weight ratio of 2-cyano-3-amino-3-ethyl phenylacrylate to clorine-nalidixic-methyl is in the range of from 1:20 to 20:1, and the weight of the active constituents is 5-60% of that of the composition. The bactericidal composition has high bactericidal activity, can delay the production and development of pathogen resistance, and can reduce preventive dosage in the real production, which is economical, efficient, safe and environmentally friendly. The bactericidal composition has the higher control efficiency for crop diseases caused by fusarium, and particularly significant in wheat scab.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicidal composition containing cyclostrobin and cloclostrobin. Background technique [0002] Wheat head blight is a widely distributed disease, which occurs in almost all wheat producing areas in the world, especially in mild and humid and semi-humid areas. To date, there are no resistant wheat varieties with complete immunity to head blight. Therefore, wheat head blight still depends on chemical control in production. At present, the main agent used to control wheat head blight in production is the benzimidazole fungicide represented by carbendazim. Since the world's first carbendazim-resistant strain of Fusarium graminearum was detected on wheat ears in Haining, Zhejiang in 1992, the resistance of the pathogen has been found in Zhejiang, Jiangsu, Lu, Anhui and other places. Moreover, the proportion of drug-resistant bacteria is rapidly increasing, and the distribu...
