Fungicide composition containing sulphur

Abstract

The invention discloses a fungicide composition containing sulphur, which is composed of sulphur, dimethomorph and other components, wherein the mass ratio of sulphur to dimethomorph is 10:1 to 1:4; and other components are at least one selected from a dispersing agent, a wetting agent, a binding agent, a disintegrating assistant agent, a thickening agent, an anti-freezing agent, a defoaming agent and a filling material. The fungicide composition disclosed by the invention has high efficiency, broad spectrum, low toxicity, safety, multiple functions and biological rationality; simultaneously, the fungicide composition is also beneficial to delaying generation and development of pathogenic bacteria on drug resistance to fungicide, so that the service life of the fungicide is prolonged; the composition disclosed by the invention can be processed into a suspending agent, water dispersible granules and wettable powder, which can overcome disadvantages of missible oil preparation; therefore, the use amount of an organic solvent is greatly reduced, the toxicity, the production cost and the use cost are reduced; furthermore, the fungicide composition is beneficial to protecting the ecological environment; and the composition disclosed by the invention enlarges the bacteriocidal spectrum and has special effects on diseases, such as powdery mildew of crops, leaf spot disease, anthracnose, rust disease, downy mildew and epidemic disease.

Description

technical field [0001] The invention relates to a fungicide composition containing sulfur. Background technique [0002] Sulfur is an important species of inorganic pesticides. It has bactericidal and acaricidal effects, and has good control effect on wheat, melon, eggplant and grape powdery mildew, and has high control effect on wolfberry and citrus rust mite. Its bactericidal mechanism is to act on the electron transfer process between the redox system cytochrome b and c, capture electrons and interfere with normal redox. Sulfur is a non-systemic protective fungicide and has no therapeutic effect. However, due to the wide range of uses and low price of sulfur, it is often compounded with some systemic pesticides in the prevention and control of agricultural plant diseases. [0003] Dimethomorph amide fungicides are specific oomycete fungicides, and their action is characterized by destroying the formation of cell wall membranes, and they have effects on all stages of th...

Problems solved by technology

However, there is a relatively high risk of resistance when used alone, so it is often used in combination with some protective fungicides to delay the emergence of resistance.
