Extract

During the past three years a great deal of attention has been paid to the use of derris and pyrethrum as basic, non-poisonous insecticidal material. This work was stimulated primarily by the tolerance placed upon arsenicals and other so-called poisonous insecticides. Considerable progress has been made and a number of formulae have been developed for the control of certain insect pests with the use of derris and pyrethrum that give safe, effective and economical kill. New applications are constantly being devised and it is the purpose of this paper to briefly review some of the newer developments in the field of derris and pyrethrum investigations.
