Problems solved by technology

[0003] Plant inducers are new types of pesticides composed of plant resistance-inducing factors, which have broad application prospects, especially for diseases that are difficult to control with general chemical pesticides, such as viral diseases, fusarium wilt and Verticillium wilt, etc. At present, the plant inducers registered by the state use amino oligosaccharins as the main ingredients to induce disease resistance, but all the products currently registered are water preparations. This dosage form has structural and performance stability problems during storage, which affects its Promotion and application, for this purpose, the development of solid amino-oligosaccharin products

Abstract

The invention discloses an oligosaccharides induced-resistance agent effervescent tablet and a preparation method thereof. The oligosaccharides induced-resistance agent effervescent tablet comprises the following raw materials by weight percent: 0.5-40.0 percent of plant induced-resistance agent raw powders, 18.0-30.0 percent of solid organic acid, 30.0-40.0 percent of carbonate, 10.0-15.0 percentof a drier, 1.0-1.5 percent of a glidant and 1.0-13 percent of a promoter. Compared with the prior art, the invention has the advantages of easy dissolution in water, convenient transportation and storage, no agglomeration due to moisture and convenient use.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to an oligosaccharide plant inducer effervescent tablet and a preparation method thereof. Background technique [0002] The mutual recognition of plants and pathogenic bacteria depends on the interaction between the two cell surface molecules. Pathogens invade host plants through interactions between cell surface molecules. When pathogenic bacteria invade host plants, through the interaction between cell surface molecules, a series of reactions occur in the plant and induce the production of new substances in the plant. According to this molecular recognition mechanism, when no pathogenic bacteria exist, when the plant cell wall is stimulated by certain substances such as: inorganic salts, small organic molecules, biological macromolecules and fungal cell walls, a series of reactions can occur in the plant. Through this series of reactions , through this series of reactio...
