|How long does the fumigant sulfuryl fluoride (Vikane) persist in soil? I had my house fumigated last week and agapanthus and liriope plants at least four feet from the house foundation are continuing to die.

|Vikane is manufactured by Dow-Elanco and is used as a fumigant (generally against termites). Since it is a gas, it dissipates rapidly, and should have little adverse affect on vegetation outdoors.
