Six methods for rescuing Silkworm poisoning
1. Bleach antidote. For mulberry leaves contaminated by bacterial pesticides, 0.15-0.25 kg of bleach and 50 kg of water can be used to form a bleach solution. The clear liquid was sprayed on the surface and back of mulberry leaves, and then fed to silkworms after the mulberry leaves had no medicinal taste.
2. Atropine aqueous solution. When silkworms are poisoned by organophosphorus pesticides and arsenic-containing pesticides, 0.3 grams of atropine tablets or 0.5 grams of atropine water can be used to wash the poisoned silkworms or spray them on mulberry leaves for 0.5 kilograms of cold boiled water. until the silkworm has no symptoms of poisoning.
3. Phosphorus chloride aqueous solution. When organophosphorus pesticides pollute mulberry leaves and lead to silkworm poisoning, use 0.25 grams of 1 dose of phosphorus chloride injection 2 grams, 0.5 kg of cold boiled water, wash silkworms or spray mulberry leaves to add food until asymptomatic.
4. Licorice aqueous solution. When silkworms are poisoned by pesticides and tobacco contaminated mulberry leaves, licorice can be boiled with 0.5 kg of licorice and 2.5 kg of water and boiled for 30 minutes. After cold, the silkworms are sprayed with leaves to return to normal. Licorice aqueous solution can be prepared in advance, bottled and sealed for use.
5. White alkali solution. When silkworms are poisoned by permethrin pesticides or insecticidal double contaminated mulberry leaves, 0.1 kg of white alkali can be ground into powder and 10 kg of water can be mixed into alkaline water solution to rinse or wash the poisoned silkworms, which can save the lightly poisoned silkworms.
6. Lime paste. As the mulberry leaves polluted by factory smoke and fluoride often cause deformities or growth retardation after feeding silkworms, 0.25-0.5 kg of lime and 50 kg of water can be used to form lime slurry and spray leaves to feed silkworms, which can play a role in detoxification.

Key points of rearing large silkworm in autumn
The main reason for instable production of silkworm in autumn is silkworm disease. With the increase of silkworm rearing times, the number of pathogens increased, the spread area increased, the virus was fresh and reproduced quickly, and the pathogenicity was high. If the silkworm rooms and silkworm tools are not disinfected thoroughly, the management of rearing is relaxed, and the silkworm is in a bad environment of high temperature and humidity or high temperature and dryness in autumn, the mulberry leaves are poor in quality, and the silkworm disease resistance is weak. These are the main reasons for the outbreak of silkworm diseases in autumn. 1. Strengthen disinfection to prevent diseases and eliminate the source of diseases. Effective measures to prevent silkworm diseases are disinfection and elimination.
