Problems solved by technology

In the third stage, the new compound types represented by imported kresoxim-methyl have a unique mechanism of action, more action sites, and are more specific in treating powdery mildew, and the effect can reach more than 90%. After use, obvious drug resistance has been produced, and the effect has declined
[0007] There is no report on the combination of Zhongshengmycin and benzovinfluconazole and its application

Embodiment 1

[0021] Example 1: Indoor toxicity test of Zhongshengmycin · benzovinfluconazole on Blumiria graminis.

[0022] The test object was collected from the wheat powdery mildew pathogen Blumiria graminis in the field, and the method was based on the "People's Republic of China Agricultural Industry Standard NY / T 1156.4-2006", pot test method.

[0024] Indoor Toxicity Test Results for Blumiria graminis

[0025]

[0026]

[0027] It can be seen from Table 1 that the mixing ratio of Zhongshengmycin and benzovinfluconazole is between 30:1 and 1:30, which has obvious synergistic effect on Blumiria graminis, and the co-toxicity coefficient All above 170, the mixing ratio of Zhongshengmycin and benzovinfluconazole is between 20:1 and 1:20, which has obvious synergistic effect on Blumiria graminis, and the co-toxicity coefficient Both are above 200.

Embodiment 2

[0028] Example 2: Indoor toxicity test of Uncinula necator.

[0029] The test object is grape powdery mildew pathogen Uncinula necator collected from the field, and the method refers to the "People's Republic of China Agricultural Industry Standard NY / T 1464.12-2007" and "The People's Republic of China Agricultural Industry Standard NY / T 1156.4- 2006".

[0032]

[0033]It can be seen from Table 2 that the mixing ratio of Zhongshengmycin and benzovinfluconazole is between 30:1 and 1:30, which has obvious synergistic effect on grape Uncinula necator, and the co-toxicity coefficient is average. Above 150, the mixing ratio of Zhongshengmycin and benzovinfluconazole is between 20:1 and 1:20, which has obvious synergistic effect on grape Uncinula necator, and the co-toxicity coefficients are all in the More than 200.

Embodiment 3

[0034] Example 3: Indoor toxicity test of Zhongshengmycin · benzovinfluconazole on powdery mildew (Sphaerotheca fuliginea).

[0035] The test object is the cucumber powdery mildew pathogen Sphaerothecafuliginea collected from the field, and the method refers to the "People's Republic of China Agricultural Industry Standard NY / T 1156.4-2006" and "The People's Republic of China National Standard GB / T 17980.30-2000" .

Abstract

The invention discloses a synergistic bactericidal composition, the active ingredients of which are Zhongshengmycin and benzovinfluconazole, including common auxiliary agents, Zhongshengmycin and benzovinfluconazole, Zhongshengmycin and benzovinfluconazole The weight-to-number ratio of fluconazole is 30:1-1:30. The bactericidal composition of the invention has a synergistic effect on pathogenic fungi and is suitable for preventing and controlling crop diseases caused by pathogenic fungi and bacteria. The present invention exhibits obvious synergistic or additive effects within a certain proportion range, and the control effect of the composition on germs is significantly improved compared with that of a single agent, which reduces the dosage of pesticides, reduces the frequency of medication, and reduces the cost of medication , reducing the adverse effects of pesticides on the ecological environment.

Description

technical field [0001] The invention relates to a synergistic bactericidal composition, the active ingredients of which are Zhongshengmycin and benzovinfluconazole, which are suitable for preventing and treating crop diseases caused by pathogenic fungi and bacteria. Background technique [0002] Powdery mildew is a worldwide disease that occurs widely on many important crops, is seriously harmful, and is difficult to control. There are many types of pathogenic crops. This type of bacteria can germinate when the temperature reaches 10-30°C, and the spores can germinate, and the humidity requirement is not high. Under normal circumstances, an infection cycle can be completed in 10 days; therefore, the crops can be repeatedly infected many times in one growing season. Once the characteristics of rapid outbreak and epidemic occur, especially in the greenhouse environment, it will cause irreparable and huge losses to agricultural production. In agriculture, in the first stage, i...
