Pesticide Leachability Chart




The pesticides listed on this chart are identified by brand names, common name and rating for movement by leaching (low, medium or high). Identify the pesticides stored on your property 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.
