Embodiment 1

[0014] Bioassay Example 1: Toxicity determination of bromothalonil and dicyanoanthraquinone complex on apple ringworm

[0015] The indoor toxicity of the mixture of bromothalonil and dicyanoanthraquinone to apple ringworm was studied by the method of mycelium growth rate. The experimental method used Sun Yunpei's method to calculate the co-toxicity coefficient (CTC) to evaluate the mixed effect. CTC When the value is greater than 120, it is considered that the mixture has a synergistic effect, when it is less than 80, it is considered an antagonistic effect, and when it is between 80 and 120, it is considered to have an additive effect.

[0016] The specific method is as follows:

[0017] Take the prepared medicinal solution and put it in 100ml of 50-60℃ PDA sterilized medium, shake well, pour it into a sterilized petri dish with a diameter of 60mm, after cooling and solidifying, transplant the bacteria cakes with uniform growth and a diameter of 4mm, The sterilized medium ad...

Embodiment 2

[0028] Bioassay Example 2: Toxicity determination of bromothalonil and dicyanoanthraquinone complex to cucumber downy mildew

[0029] The indoor toxicity of bromothalonil and dicyananthraquinone to cucumber downy mildew was determined by plate leaf method. Test method: Put the cucumber leaves in a petri dish for moisturizing treatment, spray the pesticides according to the designed doses, inoculate cucumber downy mildew bacteria after 24 hours, and culture them in an incubator with moisture, investigate the control effect after 7 days, and use the disease index Calculate the control effect, use DPS data processing software for statistical analysis, calculate the EC50 of each agent, and use Sun Yunpei's method to calculate the co-toxicity coefficient (CTC) to evaluate the mixed use effect. The test results show that the combination of bromothalonil and dicyanoanthraquinone has good indoor toxicity to cucumber downy mildew, and the CTC values ​​of all the ratios are more than 12...

Abstract

The invention relates to a sterilization composition containing bromothalonil and dithianon and application thereof. The ratio of the bromothalonil to the dithianon in portions by weight in the composition is 100:1-1:100, and the content of active components in percentage by weight in the composition is 1-90%. The sterilization composition recomposes the bromothalonil and the dithianon so as to achieve the synergistic effect. The composition is used for preventing and curing multiple diseases of leaf spot, anthracnose, ring spot, downy mildew, banana freckle, alternaria leaf spot,scab, rust disease and the like on fruit trees and vegetables, and has the advantages of germ resistance extension, high efficiency, low toxicity, wide application range and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition compounded with bromothalonil and dicyanoanthraquinone, which is used for preventing and treating crop diseases, especially diseases on fruit trees and vegetables. technical background [0002] In recent years, with the adjustment of the rural planting structure, the planting area of ​​fruit trees has continued to increase, and the occurrence of many diseases on fruit trees has also increased, such as ring spot on apple trees, leaf spot, anthracnose, pear scab , peach and apricot brown rot, grape downy mildew and other diseases are serious, and difficult to control, so that my country's fruit farmers suffer huge economic losses every year. According to statistics, the economic loss caused by apple spot leaf defoliation and ring spot damage in my country is as high as more than 3 billion yuan every year. At present, because old agents have...
