Abstract:

For several years investigations have been carried on at the Oregon Agricultural Experiment Station to determine the relative insecticidal values of the different insecticides in common use. The problems taken up have involved both chemical and entomological work and the data obtained show some very interesting results. Among other things the work done has shown that there are two different arsenates of lead present in the commercial material and that they are quite variable in their action and efficiency. We designate these compounds as lead hydrogen arsenate (acid) and basic lead arsenate (neutral) and experiments made, using both substances in a pure state, show that the first is quicker acting than the second and apparently more efficient in strengths containing equal amounts of arsenic. The data presented in this paper deal with experiments conducted to determine the comparative toxic value of these compounds.
