Abstract

The invention discloses a metconazole water suspension bactericide capable of adjusting crop physique. The metconazole water suspension bactericide comprises the following components: 5-70 wt% of metconazole raw medicine, 1-15 wt% of a dispersing agent, 0.1-10 wt% of a wetting agent, 0.5-10 wt% of a thickening agent, 0.5-10 wt% of an anti-freezing agent, 0.01-0.3 wt% of a conditioning agent, 0.01-3 wt% of a preservative, 0.01-0.5 wt% of a defoaming agent and the balance of water. The metconazole water suspension bactericide overcomes the defects of wettable powder, and has the advantages of environmental protection and low use cost. In the processing and using process, pollution to the environment is reduced, the safety of a user is improved, the using cost of farmers is reduced, and the method is the development trend of pesticide preparations at present.

Description

technical field [0001] The invention belongs to the technical field of plant fungicides, and in particular relates to a metconazole water-suspended fungicide which not only has a good fungicidal effect but also can properly regulate plant growth and a preparation method thereof. Background technique [0002] Meconazole, also known as oxyconazole, chemical name: 5-(4-chlorophenyl)-2,2-dimethyl-1-(1,2,4-triazol-1-ylmethyl)- Cyclopentanol. Meconazole is a new broad-spectrum systemic fungicide. Its function is characterized by: inhibiting the biosynthesis of ergoziol in pathogenic bacteria, causing the formation of cell membranes and the growth of hyphae, thereby achieving the bactericidal effect. After the agent is sprayed, it can be quickly absorbed and conduct two-way conduction to kill the invading pathogenic bacteria and spores. It is a systemic fungicide with preventive and therapeutic effects. It is mainly used for the prevention and treatment of Septoria, Fusarium pan...
