Pesticide Leachability Chart

The pesticides listed on this chart are identified by brand name, common name, and rating for movement by leaching (low, medium, or high). Identify the pesticides stored on your farmstead from the listing below. Note the "leachability factor" for each pesticide you store. Then give yourself an overall "leachability ranking" (low, medium, or high), based on which ranking best represents the pesticides you store. Then use this ranking to complete the "Leachability" section on the assessment work sheet.
