Abstract

The invention belongs to the field of agriculture, and relates to a composition of fungicidal active compounds, in particular to a composition comprising picarbutrazox and other fungicidal active compounds and its formulation and application. A bactericidal composition comprising a bactericidal active compound I and a bactericidal active compound II, the bactericidal active compound I is picarbutrazox, and the bactericidal active compound II is selected from lipids and membrane synthesis inhibitors; cell mitosis inhibitors; Amino acid and protein synthesis inhibitors; multi-point combined activity; inducing host plants to produce resistance; nucleic acid synthesis inhibitors and other fungicides. The bactericidal composition has a synergistic effect, delays drug resistance, improves the compatibility with plants, and can control various diseases at the same time, thereby meeting the needs of agricultural production. The second object of the present invention is to provide a formulation of the above-mentioned germicidal composition. The third object of the present invention is to provide the application of the above-mentioned bactericidal compositions and preparations.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a composition of fungicidal active compounds, in particular to a composition comprising picarbutrazox and other fungicidal active compounds and its formulation and application. Background technique [0002] In the actual production of crops, crops often encounter various diseases caused by the infection of various pathogens, such as sheath blight, blight, downy mildew, gray mold, anthracnose and other diseases. In addition to the necessary agricultural measures to control these diseases, the use of fungicides is essential. At present, the active compounds for controlling crop diseases mainly include triazoles, methoxyacrylates, pyrroles, pyrimidines, amides, copper preparations, etc. However, in most cases, the activity of a single fungicide often cannot meet the needs of multiple pathogens that are often faced in agricultural production at the same time, and the repeated use of a singl...
