Description

Technical Field

[0001] This invention relates to the fields of pesticide adjuvants and plant protection, specifically to an agricultural adjuvant with anti-flocculation function, its preparation method, and its application. Background Technology

[0002] Amino oligosaccharides are biopesticides produced from marine organisms using unique biotechnology. Their structure is characterized by the following features: amino oligosaccharides are oligosaccharides composed of D-glucosamine linked by β-1,4 glycosidic bonds. This means that the glucose units in their molecules are linked by specific chemical bonds, forming a sugar chain. This linkage gives amino oligosaccharides a certain degree of stability and a specific spatial structure, which is crucial for their biological activity. Each D-glucosamine unit carries an amino group (-NH2). The presence of these amino groups gives the amino oligosaccharide molecule an overall positive charge, making it a positively charged cationic basic amino oligosaccharide found in nature.

[0003] Polyoxin is a peptidyl pyrimidine nucleoside antibiotic with a basic group in its molecular structure. These basic groups can be protonated under certain conditions, giving the polyoxin molecule a positive charge and exhibiting cationic properties. This cationic property allows it to attract negatively charged components (such as cell wall components) on the surface of pathogenic cells (through electrostatic attraction) during disease control. This helps polyoxin adhere better to the pathogen surface, thereby inhibiting pathogen growth by interfering with physiological processes such as chitin synthesis in the pathogenic cell wall, thus achieving disease control.

[0004] In summary, both amino oligosaccharides and polyoxin are cationic pesticides. The presence of a positive charge allows them to interact with substances carrying a negative charge. Since many adjuvants in pesticide formulations, such as phosphate esters (salts), sulfonates (salts), polycarboxylate salts, calcium dodecylbenzenesulfonate, and xanthan gum, carry a negative charge, and chemically synthesized active ingredients often carry negatively charged groups, these cationic pesticides can effectively reduce the negative charge on the surface of these substances under charge neutralization, thereby lowering their Zata potential and causing them to destabilize and settle.

[0005] In modern agricultural production, tank mixing of pesticides has become a common application method to improve pest and disease control, reduce the number of applications, and lower costs. However, cationic pesticides containing amino oligosaccharides, polyoxin, and other similar products may experience flocculation and precipitation when mixed with other products in tanks. This not only affects the effectiveness of the pesticides but may also cause phytotoxicity to crops. Therefore, there is an urgent need to develop an adjuvant that meets the tank mixing compatibility requirements of cationic pesticides. Summary of the Invention
