Does anyone know if it's available over here.  I planted 92, 1 year old olive trees in March last year.  They've progressed well but this year, quite a few of them have suffered "die back".  I appear to have rescued some of them with pruning but others have died completly.  From what I can make out, the cause is verticillium wilt.  I need to re-plant about 20 new trees but don't want to risk infecting those as well so I want to sterilise the soil first.  Solarisation would seem to be the obvious answer but not really practical in 20 different spots.  The heat at the moment would do the job but of course there's no telling if it will last the couple of months it would take.  I reckon Jeyes would be easier.  I know there are some sorts of EU bans in place but thought that it may be available despite that.  Any other suggestions most welcome.
Cheers,
