Problems solved by technology

However, the single prevention and treatment of this type of disease, coupled with the high mutation frequency of the pathogen itself, has resulted in the pathogens developing different degrees of resistance to these agents, and their resistance genetics are very stable

Embodiment 1

[0081] The indoor toxicity of different ratios of Bacoud and difenoconazole to banana leaf spot was determined by spray method.

[0082] Table 1 Indoor toxicity test and ratio screening of the combination of Baket and difenoconazole against banana leaf spot

[0083]

[0084] The results showed that there was an obvious synergistic effect between Bacata and difenoconazole at a ratio of 100:1-1:100, and the co-toxicity coefficient was above 120.

[0085]

example 2

[0086] Biological Assay Example 2 The spray method was used to determine the indoor toxicity of different proportions of Bacoud and difenoconazole to apple leaf spot disease.

[0087] Table 2. Indoor toxicity determination and ratio screening of the combination of Baket and difenoconazole against apple leaf spot disease

[0088]

[0089] The results show that Bacata and difenoconazole have obvious synergistic effects in the ratio of 100:1-1:100, and the co-toxicity coefficient is above 120.

[0090]

example 3

[0091] Biological Assay Example 3 Using the spray method to determine the indoor toxicity of different proportions of Bacoud and difenoconazole compounded against wheat take-all

[0092] Table 3 Indoor toxicity test and ratio screening of Baket and difenoconazole against wheat take-all

[0093]

[0094] The results showed that there was an obvious synergistic effect between Bacata and difenoconazole at a ratio of 100:1-1:100, and the co-toxicity coefficient was above 120.

Abstract

The invention relates to a bactericidal composition with a synergistic effect, and in particular relates to a bactericidal composition containing bellkute and difenoconazole. The weight ratio of the bellkute to the difenoconazole is 1:100 to 100:1; and the bellkute and the difenoconazole together account for 5%-90% of the bactericidal composition by weight. The bactericidal composition provided by the invention is applied to prevention and treatment of leaf spot disease, banded sclerotial blight, full rot, rust disease, anthracnose, early blight, powdery mildew, gray mold, leaf blight, purpura, loose kernel smut, scab, black spot, alternaria leaf spot, stem wilt, soft rot of fruits, and diseases of fruits in a storage period. The invention also relates to application of the bactericidal composition containing the active ingredients of the bellkute and the difenoconazole to protection of plant propagation materials and plant organs grown later. The composition provided by the invention is wide in antimicrobial spectrum, has both prevention and treatment effects, has good prevention and treatment effects to the plant diseases, and further is capable of retarding or avoiding the resistance to drugs of pathogenic bacteria.

Description

technical field [0001] A bactericidal composition containing Bacata and difenoconazole of the present invention relates to a bactericidal composition with a synergistic effect. The bactericidal composition is used in the field of agricultural plant chemical protection. Harmful fungi in agriculture or horticulture exhibit extremely strong antibacterial and bactericidal activities. technical background [0002] A variety of fungal diseases often occur on agricultural and horticultural crops (cereals, fruits, vegetables, flowers), such as gray mold, powdery mildew, sclerotinia, stem blight, creeping blight, anthracnose, ring spot, Scab, leaf spot, spotted leaf spot, fruit soft rot, blue mold, green mold, rust, peach brown rot, smut, stripe spot, etc. [0003] Bellkute, biguanidine octylamine, mainly plays a role in the biosynthesis of fungal ester compounds and cell membrane function, inhibits spore germination, germ tube elongation, formation of appressoria and hyphae, and is...
