Citrus Tree Leaf Disease/Fungus
I've started to notice a sort of fungus or disease on the leaves of my Meyer Lemon and lime trees. It looks like a silvery squiggly trail, almost as if a snail has slid around on the leaf. After about two weeks the leaf will begin to roll up and die. I have been cutting off any leaf that I identify with it, trying to stop the spread, but I don't really know how it spreads. It only seems to be affecting new leaves. I've bought a fungicide but I really don't want to use it blindly, not knowing what I am treating. Does anyone know what it is? I've researched citrus tree fungus/disease, but I can't find anything that describes what this looks like. Any thoughts? I really need to figure it out!
