Shortly after emerging in February, the newly budding leaves on my plant have wilted. The plant is well established and usually gives strong growth. I suspect a route or soil pest problem. What should I do to eradicate the soil pest/disease before replacing the plant with another of the same type?

Have you already dug that bush up? I find Buddleias very tough plants..rarely effected by pest or deseases. The most usual suspect for damageing or even killing new growth in spring is frost..which often result the next lot of new growth being delayed or there might be bit of die back. There is some fungal diseases that may affect..but usually you would see some other plants there too that show some 'upset'. Fungal problems would show in the root area or in the lower wood of the dug up plants. And if that should be the case..I would not attempt to plant similar plants into same area again for a year or two. Can you see any obvious damage to the wood or bark near soil level? Other than fungal problems..only pest I can think of being able to cause that sort of havoc is rabits or hare..during winter they can chew through bark and kill quite big plants and young trees.

As above: Buddleia will withstand really nasty growing conditions and is as close to impossible to kill as any plant I've ever encountered. However, my Buddleia's suffered some frost damage several weeks ago (first time ever, but we had record-low temperatures here in February) which killed all the new leaves, but the plants are bouncing back again now. In the unlikely event that your problems is a pest/disease in the soil, it'd probably be either nematodes or fungi. They are difficult to eradicate as it is not easy to effectively use chemicals on the soil. The best that can be done is to plant something different (therefore avoiding replant disease) or to excavate a generous area and fill with fresh soil to allow a new plant to establish.
