Application of levofloxacin hydrochloride in preparation of pesticide preparation for controlling banana bacterial soft rot

Abstract

The invention discloses an application of levofloxacin hydrochloride in preparation of a pesticide preparation for controlling banana bacterial soft rot. Levofloxacin hydrochloride can be used for preparing soluble powder for controlling banana bacterial soft rot; the levofloxacin hydrochloride soluble powder is prepared from the following components in percentage by mass: 50%-70% of levofloxacinhydrochloride, 10%-20% of soluble filler and 10%-40% of an aid. The filler and the aid are added to the levofloxacin hydrochloride raw medicine, the mixture is stirred and mixed uniformly and then ispulverized by a pulverizer, and the levofloxacin hydrochloride soluble powder is obtained. The levofloxacin hydrochloride soluble powder has rapid bactericidal effect on bacteria of banana bacterial soft rot, and can be sprayed in high-temperature and high-humidity seasons to prevent diseases; or, the levofloxacin hydrochloride soluble powder is sprayed in the initial stage of banana bacterial soft rot to prevent occurrence and spread of the disease, the control effect on the disease is good, and accordingly, a new storage technology is provided for control of banana bacterial soft rot.

Description

technical field [0001] The invention belongs to the field of crop disease prevention and control, and particularly relates to the application of levofloxacin hydrochloride in the preparation of pesticide preparations for preventing and treating bacterial soft rot of bananas.
