The Calcium Arsenates

THE CALCIUM ARSENATES By R. H. ROBINSON Acting Chemist, Oregon Agricultural Experiment Station INTRODUCTION Chemical investigations on the calcium arsenates relative to their economfic value and practicability as insecticides have been carried on by the department of Agricultural Chemistry of this Station during the past two years.The results obtained from these investigations are presented in this bulletin.The work was supported by the annual funds provided by the Adams Act of the United States Government.. Commercial calcium arsenate is an arsenical now being produced by reliable manufacturers of spray material and offered for sale as a sub- stitute for the arsenates of lead.The value of the latter as a stomachic insecticide has been demonstrated, and itis now used extensively for the successful controlof the codling moth, the destructionof the cotton boll worm., the tobacco worm, and the Colorado potato beetle. Previous inveatigations on the toxic values and killing power of calcium arsenate and lead arsenate indicate equal efficiency. A consideration of a few figures will show the economic advantages which might be gained if calcium arsenate could be substituted for lead arsenate.A conservative estimate of the quantity of lead arsenate used annually in the United States, as stated by one of the largest manufac- turers of spray materials, is probably more than 30,000,000 pounds. -

Historical Use of Lead Arsenate and Survey of Soil Residues in Former Apple Orchards in Virginia
HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA by Therese Nowak Schooley Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN LIFE SCIENCES in Entomology Michael J. Weaver, Chair Donald E. Mullins, Co-Chair Matthew J. Eick May 4, 2006 Blacksburg, Virginia Keywords: arsenic, lead, lead arsenate, orchards, soil residues, historical pesticides HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA Therese Nowak Schooley Abstract Inorganic pesticides including natural chemicals such as arsenic, copper, lead, and sulfur have been used extensively to control pests in agriculture. Lead arsenate (PbHAsO4) was first used in apple orchards in the late 1890’s to combat the codling moth, Cydia pomonella (Linnaeus). The affordable and persistent pesticide was applied in ever increasing amounts for the next half century. The persistence in the environment in addition to the heavy applications during the early 1900’s may have led to many of the current and former orchards in this country being contaminated. In this study, soil samples were taken from several apple orchards across the state, ranging from Southwest to Northern Virginia and were analyzed for arsenic and lead. Based on naturally occurring background levels and standards set by other states, two orchards sampled in this study were found to have very high levels of arsenic and lead in the soil, Snead Farm and Mint Spring Recreational Park. Average arsenic levels at Mint Spring Recreational Park and Snead Farm were found to be 65.2 ppm and 107.6 ppm, respectively. -

THE ELECTROLYTIC OXIDATION OF POTASSIUM ARSElHTE. Potassium arsenate is a comparatively unknown compound, that is, very little experimental work has been done with it, and since no important use has been found for it no attempt has been made to produce it in large quantities. Several arsenic compounds are very useful in destroying insects whic~ have prov,en themselves enemies to the life of eco nomi~ plants. Probably the first of these was the well-known Paris Green which contains copper and acetic acid as well as ar senic. As copper was a fairly expensive metal, and since the acet ic acid served no useful purpose, this was followed and to acer tain extent replaced by lead arsenate, which does the same work at a considerably less coat. The users of Paris Green usually ass ociated the green color, due to copper, with its effectiveness, so that arsenate of lead, which is white, had a strong prejudice to overcome at first. Another member of the arsenic family to come into prominence is calcium arsenate. -
