What to do with my lemon tree?

gimanOctober 6, 2013

Patchy brown spots on leave and wonder if it's fungal related. Any advice to remediate is much appreciated.

Also, what is the strongest pest control spray for ants on lawns and around house?

And, what is best pest control spray for fruit trees? what is the frequency and concentration to spray?

Looks a lot more like insect damage than any fungal issue but would need a clearer, close-up photo to assess properly. Also the possibility of a viral issue but this looks like it is focused on new growth, which is much more suspect of insect problems. Any stickiness noted?

It is not a simple matter of prescribing a "pest control spray" for fruit trees. One needs to know exactly what the problem to be treated is before being able to make any recommendations. Often a dormant spray of horticultural oil can be useful for insect control but is unnecessary unless a problem really does exist. It is never a good idea to spray without a specific intent.

Ants tend not be an issue in my area so I'll let someone else speak to that. Baiting with borax is all that is ever really necessary here.
