Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, and particularly relates to an agricultural composition, a preparation method thereof, and an application thereof. Background Art

[0002] On the one hand, new pesticides, fertilizers, and biostimulant products can be developed, promoted, and rotated for use, but the difficulty of developing new products is increasing continuously; on the other hand, the efficacy can be improved through innovations in formulation technology and application technology, while reducing the application amount and frequency. As commonly used low-toxic additives or auxiliaries in industry, phthalocyanine blue and alkyl polyglycoside are widely used in the agricultural field. The organic pigment phthalocyanine blue is used as a product identification color or warning color due to its strong coloring power, and the alkyl polyglycoside synthesized from glucose and fatty alcohol is used as a surfactant with functions such as dispersion and wetting due to its high surface activity, safety, and stability. In addition, both phthalocyanine blue and alkyl polyglycoside are considered to have certain antibacterial and bacteriostatic effects, but their action mechanisms are different. The alkyl polyglycoside exerts its antibacterial effect through multiple mechanisms, including interfering with bacterial protein synthesis, changing the bacterial cell membrane structure (such as destroying the lipid layer, etc.), and interacting with bacterial DNA, etc.; the antibacterial and bactericidal mechanism of phthalocyanine blue may mainly involve the following two aspects: (1) copper ions destroy the cell membrane and cell wall of pathogenic bacteria, or bind to the enzymes in pathogenic bacteria to hinder their normal activity and affect their normal metabolism and survival; (2) photoactivation activation generates superoxide anions, hydrogen peroxide, and hydroxyl anions to change the functions of pathogenic microbial cells and tissues, or generates hydroxyl oxides and singlet oxygen, etc. to cause damage to the biological cell membrane and DNA of pathogenic bacteria. Incorporating phthalocyanine blue into an alkyl polyglycoside system with moisture retention, high stability, good compatibility, and compatibility, or further compounding it with pesticide, fertilizer, and / or biostimulant components is expected to obtain a new agricultural composition.
