Embodiment 1

[0052] Example 1, Indoor Toxicity Determination of Thiobacterium Copper and Shenzimycin Compounded to Tomato Fusarium Wilt

[0053] Test object: Fusarium oxysporum

[0054] Test method: refer to the mycelial growth rate method of "Agricultural Industry Standard NY / T 1156.2-2006 of the People's Republic of China". Set 5 doses for each agent according to the content of active ingredients, and culture the above-mentioned pathogenic bacteria with PDA medium. The bacterial 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, the colony diameter (cm) of each treatment was measured with a caliper by the cross method, and the corrected inhibition percentage was calculated. Through the linear regression analysis between the probability value of the inhibition rate and the logarithmic value of the serial concentration, the EC of each drug is calculat...

[0064] Example 2, Indoor Toxicity Determination of Thiobacterium Copper and Shenzimycin Compounded to Strawberry Root Rot

[0065] Test object: Strawberry root rot fungus (Pythium sp). The test method and drug efficacy calculation refer to Example 1.

Abstract

The invention relates to a sterilization composition containing thiediazole copper and phenazino-1-carboxylic acid and a sterilizing agent of the sterilization composition. The sterilization composition contains active components including thiediazole copper and phenazino-1-carboxylic acid. The sterilization composition has the advantages that the effects can be stacked and promote one another, the advantages of thiediazole copper and phenazino-1-carboxylic acid are well achieved, and a synergetic effect is achieved; various root soil-borne diseases can be comprehensively prevented and treated, bacterial diseases and fungal diseases can be prevented and treated at the same time, multiple diseases are treated by one composition, agent applying time and agent applying amount are shortened and reduced, and labor intensity is reduced.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a bactericidal composition for preventing and treating agricultural diseases, in particular to a bactericidal composition containing thiabactin and shenazimycin and a bactericide thereof. Background technique [0002] In today's agricultural field, due to single drug use and other unscientific drug use methods, some bacterial and fungal diseases have become resistant to many chemicals, which has become a major problem in the process of agricultural sterilization. Due to the resistance of the bacteria, the frequent application of pesticides by farmers has resulted in increased cost of pesticides and aggravated environmental pollution. Some high-efficiency new drugs, if used alone for a long time, also face the risk of developing drug resistance. In addition, due to the high price of newly developed drugs, it is difficult to fully promote and apply them in the market. Therefore, it has bec...
