Guernsey Lily (nerine Sarniense)
Syringe with a strong decoction of green leaves and tenderbranches of the elder-tree, or with a solution of nitre made in the
proportion of 1 oz. of nitre to each gallon of water. Another good
remedy is to scatter sulphur over the leaves while the dew is upon
them, afterwards giving them a syringing of clear water.
