Rose-Bugs Killed by the Pyrethrum Powder, if Properly Applied.
he Rural New Yorker, among its brieflets, says; "The increasa of the rose-bug is killed by pure pyrethrum powder, if blown upon it through a bellows
Remarks. —There is not a doubt of this fact, when it is properly applied, i. e, actually brought into contact with the bug, as it is a soft skinned mite, and the poison is thus absorbed which must kill it. The only trouble is in not being thorough and careful enough to reach all the bugs. The pyrethrum is. also known as the Caucasian or Persian insect powder. It is imported from there under these names, and is very effectual in the destruction of insects upon which it is freely blown, except those like squash-bugs, which have a hard shell to protect them, allowing no absorption of the poisonous substances. The technical name of the plant is pyrethrum roseum, from rosa, the rose, arising, probably, from the fact of its destructive power over the rose-bug; at least I so reason, unless its own flames resemble the rose, which is not as likely to have originated its name as the fact of its destructive powers over this insect.
