Rose-Bugs Killed in Air-Slacked Lime.
Air-slacked lime, S. M. P. in the Rural New Yorker, says will kill rose-bugs on grape-vines, blown on in the same way as the pyrethrum powder; then why not kill them when at home, on the rose? I know it must, if applied thoroughly to reach them all. I should, however not want the lime to lose its strength by very long standing before using If, however, put on too freely, it may turn the leaves yellow, which is the only objection to its use.
Insecticide, or Insects on Plants, to Kill with the Juice of the Tomato Plant. —A writer in the Deutsche-Zettung states that he had an opportunity of trying a remedy for destroying green fly and other insects which infest plants. It was not his own discovery, but he found it among other receipts in some provincial paper. The stems and leaves of the tomato. are well boiled in hot water, and when the liquor is cold it is syringed over the plants attacked by insects. It destroys black or green fly, caterpillars, etc.; and it leaves behind a peculiar odor which prevents insects from coming again for a time. He states that he found this remedy more effectual than fumigat ing, washing, etc. Through neglect a house of camelias had become almost hopelessly infested with black lice, but two syringings with tomato plant decoction thoroughly cleansed them. —Gardeners' Chronicle.
