Why do you think it is Verticillium Wilt? Can you supply some images almost 9 years ago.
I agree with David some pictures would help. Verticillium wilt is a nasty disease that more often than not kills the plant outright( the entire tree will wilt and die). I'd recon you might instead have fireblight. Fireblight is very common in cherries and shows up on the branch tips and spreads downward wilting and killing the branch. The only control is to use preventative spray in the early spring (I'm not sure the mix, you'll have to call around as you'd need an applicators license to spray anyways), plant fireblight resistant trees, or to continually spray your trees for insects as its spread through sap sucking insects. If you have it you need to prune it ALL out and you need to sterilize your pruning tool between cuts or you'll spread it to your new cuts. Fireblight is a bacteria, it feeds in the sap and clogs the vascular tissue of the tree which in turns kills it. Its coomon in Rosa Plants such as roses, apples, plums etc... Verticilium wilt is fungii, it does the same thing but it starts in the roots. By the time you notice it, it has spread to the trunk and your tree and your tree is already dead. Verticilium wilt usually attacks trees that are not adapted to their proper environment as an example Drought tolerant desert Oaks planted in well watered turf i n California often die of Verticilium wilt. almost 9 years ago.
