Disinfectant for silkworm pathogenic microorganisms and application of disinfectant

Abstract

The invention relates to a disinfectant for silkworm pathogenic microorganisms and application of the disinfectant, nano titanium dioxide is used as a main agent, alkaline sodium salt is used as an auxiliary agent, and when water is used as a solvent to prepare a solution, the mass volume concentration of the nano titanium dioxide is 1mg / L-100mg / L, and the mass percent concentration of the auxiliary agent is 0.1%-1%. The alkaline sodium salt is any one of trisodium phosphate, chlorinated trisodium phosphate or sodium bicarbonate. More preferably, the mass volume concentration of the nano titanium dioxide is 20 mg / L-50 mg / L, and the mass percent concentration of the alkaline sodium salt is 0.45%-0.5%. A new application of the existing drug nano titanium dioxide is developed, and the disinfectant is safe and reliable as a silkworm drug, has a good killing effect on main pathogens BmNPV, BmCPV, bombyx mori microsporidia, beauveria bassiana, aspergillus flavus and bacillus thuringiensis spores of bombyx mori, and is an efficient broad-spectrum disinfectant for silkworm breeding.

Description

technical field [0001] The invention relates to a disinfectant composition, in particular to a disinfectant for silkworm pathogenic microorganisms and its application. Background technique [0002] The outbreak of silkworm disease has always been the biggest threat to sericulture, and every year the outbreak of various silkworm diseases will cause heavy losses. The basic principle of silkworm disease prevention and control is prevention first and comprehensive prevention and control. People mainly reduce the probability of silkworm disease outbreaks by strengthening silkworm room disinfection, silkworm seat disinfection, mulberry leaf disinfection, and improving breeding conditions. Although effective, the results are not satisfactory. Screening new drugs suitable for sericulture production from existing medicines or veterinary drugs has become a new idea for the development of sericulture. [0003] Nano-titanium dioxide is a photo-semiconductor material with photocatalyti...

AI Technical Summary

Problems solved by technology

However, this invention may not be effective for BmNPV and BmCPV, the polyhedron-embedded viruses that are the most harmful and have the highest incidence in sericulture production, because the killing of BmNPV and BmCPV needs to first destroy their polyhedron protective structure under alkaline conditions
