Problems solved by technology

[0003] However, at present, the control of plant pathogens is becoming more and more difficult. Because the resistance of pathogens will increase year by year under the pressure of continuous chemical selection, the control effect of fungicides will be greatly reduced, and the increase in the dosage of fungicides will cause environmental damage. It is not conducive to environmental protection, and the control of plant diseases is facing a major challenge, and it also puts forward higher requirements for the control of plant diseases. Therefore, it is necessary to study an efficient fungicide

Embodiment 1-10

[0029] The bactericidal composition of Examples 1-10, wherein the bactericidal composition includes the components shown in Table 1 in parts by mass.

Embodiment 1

[0030] Table 1. List of components of the fungicidal composition of Examples 1 to 10

[0031]

[0032]

[0033] The formula of embodiment 1-7 in table 1 is prepared according to the following steps:

[0034] (1) Add 8-hydroxyquinoline calcium, cymoxanil and part of water into the mixer in proportion, stir and mix evenly to obtain a premix;

[0035] (2) Add polycarboxylate, ethylene glycol, xanthan gum, silicone oil and the rest of the water into the mixer in proportion, stir and mix evenly to obtain a mixture, then add the mixture and premix to the ball mill During the grinding operation, the grinding time is controlled to be 2.5h to obtain the bactericidal composition of Examples 1-7, which is in the form of a suspension;

Abstract

The invention belongs to the technical field of bactericidal compositions, and discloses a bactericidal composition and application thereof. The bactericidal composition provided by the invention comprises 8-hydroxyquinoline calcium, cymoxanil and an auxiliary agent, wherein the mass ratio of the 8-hydroxyquinoline calcium to the cymoxanil is 1:(0.05-20). According to the invention, by using the composition containing the 8-hydroxyquinoline calcium and the cymoxanil according to the mass ratio of the 8-hydroxyquinoline calcium to the cymoxanil of 1:(0.05-20), under the proportion, the bactericidal composition has excellent activity on plant diseases, the 8-hydroxyquinoline calcium and the cymoxanil have an obvious synergistic interaction effect, and the bactericidal composition has the advantages of being small in dosage and high in bactericidal efficiency, so that the pesticide resistance of germs is overcome and delayed, the use amount of the bactericidal composition is reduced, the plant control cost can be reduced, the influence on the environment can be reduced, and environmental protection, safety and high efficiency are facilitated.

Description

technical field [0001] The invention relates to the technical field of fungicides, in particular to a fungicide composition and its application. Background technique [0002] In the planting process of plants, there are not only the problems of insect pests, but also the problems of germs. Therefore, it is necessary to prevent and control the problems of plant germs. Usually, the method of sandblasting fungicides is used to prevent and control plant germs. Fungicides The use of fungicides is an effective measure to prevent and control plant diseases. There are many types of fungicides available. According to specific plant varieties and specific types of germs, corresponding fungicides can be used to control plant germs. [0003] However, at present, the control of plant pathogens is becoming more and more difficult. Because the resistance of pathogens will increase year by year under the pressure of continuous chemical selection, the control effect of fungicides will be gre...
