Book excerpt: Excerpt from Residual Arsenic on Pennsylvania Apples in 1932: A Thesis There has been a rather wide-spread interest in the composition and removal of insecticidal residues remaining upon apples at harvest, as a result of suppression operations against the codling moth. To arrange a spraying system it has been necessary to determine the quan tities of residual arsenic upon the apple at picking time. This study was intended to determine these factors and to indicate what took place during the season of 1952. The use of chemicals as spray treatments in codling moth control has a number of limiting factors. Their efficiency depends upon the employment of effective dosages of poison, proper timing of applica tions to the trees, and thoroughness of spraying. The amount of rain fall during the growing period of the fruits also has an important bearing on the protection of apples by the spray coating applied.
