ROSE, OR SCALE BUGS
A New and Successful Remedy for. —At a recent meeting of the California Academy of Sciences, Dr. Gibbons exhibited a large bunch of beautiful roses of exceeding fragrance, and in full bloom, which he gathered from a bush in his garden that 2 months before was overrun with scale, or rose bugs, and nearly dead. He applied to it a mixture of crude petroleum and castor oil, daubing it slightly on the leaves. and stem, with a small brush, not allowing any to fall to the ground or reach the roots. Rain followed, and the plants were then throwing out their first, growth of leaves, to which the scale bugs had been directing their attention.. No sign of any scale insect could be seen in the garden.
Remarks. —He does not give the proportions; but equal parts might be used. I see no use for castor oil at all. I believe the crude petroleum to be the destroyer. See the next receipt for using kerosene to destroy Lice on Plants. I think the kerosene would do as well, or perhaps better, on the rose-bugs than the crude oil, and it can be put on handier with the atomizer than the thicker oil with a brush. These bugs being on the under side of the leaf, the bush, must be bent over, or the atomizer carried under the leaves, as tobacco smoke is done,
