    Hey Gang,

    Quick question: these azaleas have a case of lacebug that carried over from last year despite three applications of sevin, and the lacebug seems to have survived winter. Now, the shrub is exhibiting red leaves that are suggestive of leaf gall.

    I'm inclined to tackle the lacebug first (the leaf gall is a bit widespread for hand pruning), perhaps trying some imidacloprid, and then going after the leaf gall. Does anyone see an obvious problem with this approach?

    yep, I'm trying some Merit 2.5G this year on azaleas. This is the first time I've ever used it so we'll see how it works. I'm going to inspect them later on. I'll probably spray too.
