What to do when silkworms are poisoned? Prevention and control measures for silkworm poisoning

First, ensure safe feeding: do not feed "four-side mulberry" (mulberry from the edges of fields), test mulberry leaves before feeding, and only use large quantities of leaves after confirming they are non-toxic. Mulberry trees with pesticide residues should be sprayed 1 to 2 days in advance with 0.5% edible alkaline water or 1% fresh limewater, or mulberry leaves can be soaked for 1 hour in 1% edible alkaline water or 1% fresh lime slurry. Note that the sprayer must be thoroughly cleaned, and the edible alkaline water or fresh limewater must be applied generously (about 6-8 buckets per mu). If silkworms are found to have been poisoned, promptly take detoxification measures: immediately scatter burnt ash or lime powder so the silkworms stop

If silkworms are found to have been poisoned, promptly take detoxification measures: immediately scatter burnt ash or lime powder so the silkworms immediately stop eating toxic leaves, and at the same time remove the toxic leaves and silkworm excrement, and open doors and windows for ventilation. If it is organophosphate pesticide poisoning, soak the poisoned silkworms in 5000-fold atropine sulfate for 2 minutes, remove them and spread them in a cool, ventilated place, and at the same time feed them with 500-fold atropine sulfate; for poisoning by sand silkworm toxins, pyrethroids and other pesticides, feed them with 500-fold adrenaline hydrochloride; for fipronil pesticide poisoning, soak the poisoned silkworms in cold water for 2 minutes, remove them and spread them in a cool, ventilated place. In addition, to prevent silkworms from failing to spin cocoons, feed them 2 to 3 times with 500-fold atropine sulfate during the peak feeding period of the fifth instar.
