Specific measures for disease prevention and disinfection of sericulture should be targeted

sericulture

Disinfection is one of the important measures to obtain stable and high yield in silkworm rearing. Strengthening the pertinence of disinfection for disease prevention is the key to improve disinfection effect. At the same time, disinfection and disease prevention should not only be done well before silkworm production, but also during and after silkworm production. In order to enhance pertinence, the following aspects should be emphasized in the selection of disinfection methods and disinfection drugs:

Cleaning is the foundation. Comprehensive and thorough cleaning and cleaning are the basis for eliminating silkworm pathogenic microorganisms, which can remove more than 70% of germs and viruses. The dust and garbage cleaned shall be treated by centralized burial and disinfection, such as silkworm excrement, etc., which shall be buried in pits far away from silkworm rooms and mulberry gardens, sealed with mud to promote fermentation and heat generation, and sterilized by high temperature. Silkworm tools should be cleaned in live water, and should not be cleaned in dead ponds.

2. Select targeted disinfection drugs to improve disinfection effectiveness. According to the local common silkworm diseases, especially the occurrence characteristics of silkworm diseases in last season, targeted drugs and broad-spectrum disinfection drugs should be selected for disinfection in order to improve disinfection effectiveness. Such as: to kill the virus-based, should choose lime slurry or formalin lime slurry immersion; to kill fungus-based, should choose antibacterial agent "402"; comprehensive disinfection, should choose the whole kill Wei, bleaching powder, poison dissipation. In silkworm prevention, antibiotics such as kejunling and norfloxacin should be used to prevent bacterial silkworm diseases;"402" and anti-stiff powder should be used to prevent fungal silkworm diseases; fresh lime powder should be used to prevent viral silkworm diseases; and fly maggots should be used to prevent fly maggots.

3. Strengthen the management after disinfection. For cleaned, disinfected silkworm room silkworm tools, to prevent secondary pollution, properly stored. Pay attention to daily disinfection of frequently used utensils during silkworm period to ensure disinfection effect, such as mulberry picking utensils, silkworm cushion paper, covering film, mulberry cutting tools, etc.
