In 1889, William Bradford Alwood told the Albemarle
Fruit & Grape Growers [Feb.15,1889 - Charlottesville Chronicle] the following:
- He warned them against indiscriminate use of arsenic during flowering.
- White arsenic was caustic
- Paris green was better,
but precipitated; it was dangerous to use too much.
- London purple was better
- it stayed in suspension.
- He warned users to remember they were handling poisons.
- He warned them to take precautions to protect themselves.
- He warned persons handling arsenic all day - should wash at night.
- He indicated that work was being done to render arsenic insoluble in water - lessening its danger.
This made Professor Alwood Virginia's first pesticide safety educator.
