Disinfectant for culturing silkworms

Abstract

The invention relates to a disinfectant for culturing silkworms, which uses bromochlorohydantoin as a main agent and an alkaline sodium salt as an auxiliary agent, wherein when the disinfectant is prepared into solution by using water as a solvent, the mass volume density of the bromochlorohydantoin is 120 to 960 mg/L, and the mass percentage concentration of the auxiliary agent is 0.25 to 0.75 percent. When the disinfectant is prepared into powder, the mass percentage of the bromochlorohydantoin is 5 to 20 percent, and the mass percentage of the corresponding auxiliary agent is 80 to 95 percent. The alkaline sodium salt is any one of trisodium phosphate, chlorinated trisodium phosphate or sodium bicarbonate. More preferably, the mass volume concentration of the bromochlorohydantoin is 240 to 480 mg/L, and the mass percentage concentration of the alkaline sodium salt is 0.45 to 0.5 percent. The disinfectant develops novel application of the existing medicament bromochlorohydantoin; the disinfectant prepared from the bromochlorohydantoin and an alkaline compound of the trisodium phosphate, the chlorinated trisodium phosphate or the sodium bicarbonate and the like is safe and reliable, has a good effect of killing main pathogens of NPV, CPV, N. b, beauveria bassiana, aspergillus flavus, bacillus thuringiensis and toxins, and is an effective broad-spectrum disinfectant for culturing the silkworms.

Description

A kind of disinfectant for sericulture technical field The invention relates to a disinfectant composition, in particular to a disinfectant suitable for pathogenic microorganisms easily infected by silkworms. Background technique 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 page 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. Bromochlorohydantoin (benzimidazolecompound...
