Hi i have a lemon tree with leaves that are green. But down the centre of a couple of leaves is a tan colouring. I describe it as tan because i dont want to get into the brown leaves thing and watering. It isnt that. All my citrus get the same regime, and only this one has the problem.
I've removed the leaf. I washed it to see if it was a mould. But it doesnt rub off. Its also only on the top of the leaf. I had thought anthro-waddya-call-it virus, but theres nothing on the underside. Except for the main vein underside running mid third to end third of the leaf is brown. the first third and last third of the vein is green.
Clearly i need to isolate the plant just in case.
So what i need is advice on the best bacterial spray i can use, and the best fungal spray. If its a virus then either the plant lives or dies. But in that case should i remove the infected leaves , and hope i caught it? unlikely as that may be.
I've got loads of them in pots, and the thought of this spreading is a nightmare scenario for me.
Oh i checked all the citrus problem guides i could find. None of them show pictures of this.
Help!!!... please.
