  1. Kline (Hall and Dansbury, 2000). Active ingredients listed in "other" category are identified by Kline but pounds are not given;
    these were estimated based on judgment.
  2. Split of each active ingredient into lawn vs. outdoor plants/trees was based on judgment.
  3. Hagan et al. (1993)
  4. Pounds applied divided by application rate. We assume that 100 gallons of finished spray is applied to an acre, a common assumption.
  5. Acres treated for each active ingredient divided by total acres treated.
