Problems solved by technology

[0004] The long-term use of a single bactericidal agent alone cannot completely and effectively control the occurrence of germs, the cost is high, and it is easy to cause the emergence of bacterial resistance, resulting in an increase in drug application and environmental pollution. The compounding of germs can solve the problem The problem of high toxicity and poor effect of a single pesticide, low investment, short R&D cycle, and the interactive use of different pesticides can delay the emergence of drug resistance, and has a relatively ideal use effect. Therefore, pesticides with different mechanisms of action Compounding is a research hotspot in the field of pesticides
In the prior art, there is no relevant report on the compounding of cyanaprodil and blastic-methyl

Embodiment 1

[0017] Example 1: Indoor toxicity determination of cyanaprodil and blastic-methyl to Magnaporthe grisea.

[0018] Test method: potted plant method. The test refers to "Pesticide Indoor Bioassay Test Guidelines NY / T1156.8-2007". 8-10 seeds of rice were sown in each pot, and each concentration was repeated five times, and each treatment had a total of 5 pots of rice. At the three-leaf stage of rice, the chemical treatment was carried out, and the clean water treatment was used as a blank control. After 3 days of drug treatment, wash the surface spores of the cultured pathogenic bacteria with sterile water, add Tween 80, and make 1×10 6 The concentration of spores was evenly sprayed on rice leaves with a sprayer for inoculation. After inoculation, the rice seedlings were placed in a humidifying box, connected to a humidifier, shaded with a black cloth for 24 hours, and kept at 95% humidity. After 7 days of 12h / 12h light / dark cultivation, the test results were investigated. Th...

Embodiment 2

[0034] Example 2 The field control effect of cyanoxyprodil and blastic acid compound on rice blast

[0035] Test method: refer to the method in GB / T 17980.19-2000 Pesticide Field Efficacy Test Guidelines (1) Fungicides Control Rice Leaf Diseases.

[0036] Test drug:

[0037] Medicament 1: 30% cyanoxanil · blastic-methyl granule (cyanohydrin: blastic-methyl = 5:1);

[0038] Medicament 2: 55% cyanoxanil · blastic-methyl water-dispersible granules (cyanazanil: blastic-methyl = 1:1);

[0039] Medicament 3: 40% cyanamethanil·blastizolid wettable powder (cyanamethanil: riceblastisol = 1:5);

[0040] Table 2 Field control effect of cyanaprodil and blastic-methyl compound on rice blast

[0041]

[0042]

[0043] It can be seen from the above table that the combined application of cyanaprodil and blastic-methyl can significantly improve its control effect on rice blast, and has a significant synergistic effect. And field observation is safe for crops.

Abstract

The invention provides a bactericidal composition containing fenoxanil and pefurazoate and an application thereof, wherein the active ingredients comprise fenoxanil and pefurazoate, wherein the weightratio of the fenoxanil and pefurazoate is 1:20-20:1. The composition of the invention has remarkable synergistic effect and can be used for controlling rice blast.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a fungicidal composition containing cyprofen and blastic-methyl and its application. Background technique [0002] Rice blast is a fungal disease of rice caused by the rice blast fungus. It is a worldwide rice crop disease. The annual loss of rice production due to rice blast is 11%-30%. The rice blast fungus mainly uses conidia and fungi Silk overwinters on diseased rice or grain. Rice blast occurs in all stages and parts of rice, and is most susceptible to rice blast from the four-leaf stage to the tillering stage and heading stage, and leaf blast and ear blast are the most common and the most harmful. [0003] Cyanoxanil is a new type of high-efficiency amide fungicide with good systemic and long-lasting effects. It prevents the infection of Magnaporthe grisea by inhibiting the penetration from appressoria. It is a dehydrogenase for melanin biosynthesis. Inhibitors. It...
