Abstract

The invention relates to a bactericide composition containing pyraclostrobin and copper rosinate, containing pyraclostrobin and copper rosinate as effective components, wherein, the weight ratio of pyraclostrobin to copper rosinate is 1:2-3. The bactericide composition provided by the invention is characterized by that: 1, the composition has good synergism on a plurality of crop diseases within the range of certain proportion; 2, drug resistance caused by using pyraclostrobin or copper rosinate alone can be delayed greatly because pyraclostrobin and copper rosinate have different mechanisms of action and no cross-resistance between each other; and 3, pyraclostrobin is a novel bactericide with high price, while copper rosinate is cheaper, so that the combination of pyraclostrobin and copper rosinate can reduce the cost. The bactericide composition is a novel bactericide with high efficiency, low toxicity and broad-spectrum, with the advantages of long persistent period and being easy to use. Because the bactericide composition has a large number of reaction sites, the bactericide composition does not easily to generate drug resistance. Furthermore, the bactericide composition has dual functions of preventing and treating, and is capable of treating common plant diseases caused by a plurality of fungi and bacteria, such as downy mildew, epidemic disease, black spot disease, anthracnose, bacterial angular leaf spot, blight, tomato late blight of melons and fruits and the like.

Description

technical field [0001] The invention belongs to the field of pesticide fungicides, in particular to a compound composition of pyraclostrobin and copper rosinate fungicides as active ingredients. Background technique [0002] Pyraclostrobin, also known as pyraclostrobin, is a newly developed methoxyacrylate fungicide in recent years. Its mechanism of action is an inhibitor of mitochondrial respiration, which prevents mitochondria from producing and providing the energy required for normal cell metabolism. eventually leads to cell death. Pyraclostrobin has a broad bactericidal spectrum, and can control most diseases such as Ascomycetes, Basidiomycetes, Deuteromycetes, and Oomycetes. It has a strong inhibitory effect on the germination of spores and the growth of mycelium in leaves. It has protective and therapeutic activities, and has permeability and local systemic activity. It has a long-lasting effect and is resistant to rain erosion. It is widely used to control diseases...
