For many years chemists and entomologists have been seeking the hypothetical ideal insecticide, namely, a material which is toxic to insects at an economical dosage, which is not injurious to the host plant or animal sprayed or dusted with it, and which does not leave on foodstuffs a residue that is poisonous to man or domestic animals. Certain organic compounds approach closer to this ideal than any products of mineral origin, and the successful use of these against same of our most injurious insects has greatly stimulated the testing of countless organic products for insecticidal value.
