Plant bacteriostatic agent and preparation method thereof

Abstract

The invention discloses a plant bacteria inhibitor and its preparing process, wherein the active compositions include ZnMAP and ZnDAP, and the preparing process consists of using ethanol, phosphorylation agent, ammonia and zinc salts as raw materials, reacting ethanol with phosphorylation agent to obtain reaction product containing MAP, DAP and TAP, ammonizing the reaction product with ammonia, and introducint divalent zinc ions.

Description

technical field [0001] The invention relates to the field of pesticides. More specifically, the present invention relates to a plant antibacterial agent and its preparation method. Background technique [0002] Phosphorus aluminum is a phytostatic agent that has been used for a long time in China. It can be used to inhibit various pathogens in plants, especially downy mildew. In recent years, with the continuous deepening of human research on aluminum hazards in food, people have begun to strictly limit the intake of aluminum in the diet, because the aluminum in phosfoam will be absorbed by plants during the growth of crops and cause fruit poisoning. Excessive aluminum residues have affected food safety. In addition, the production of ethylphosphorus aluminum in the prior art mostly adopts PCl 3 and POCl 3 As a raw material, first of all, the by-product HCl of these raw materials in the esterification process will cause environmental pollution, and a little carelessness ...

Problems solved by technology

In recent years, with the continuous deepening of human research on aluminum hazards in food, people have begun to strictly limit the intake of aluminum in the diet, because the aluminum in phosfoam will be absorbed by plants during the growth of crops and cause fruit poisoning. Excessive aluminum residues, which affect the safety of food

In addition, the production of ethylphosphorus aluminum in the prior art mostly adopts PCl 3 and POCl 3 As a raw material, first of all, the by-product HCl of these raw materials in the esterification process will cause environmental pollution, and a little carelessness in the production process will easily cause raw material PCl 3 and POCl 3 Leakage, which not only causes environmental pollution, but also seriously endangers the health of operators
