I’ve been paying a lot more attention to leaf infections lately, and with this being my first autumn on Inat I’ve run across an embarrassing problem. I can’t figure out how to tell whether or not a plant is dealing with an infection or just undergoing seasonal changes. Is there a particular pattern in seasonal coloration change, it begins at one part of the leaf and spreads, for example? Will this change happen in spots on the leaf, or all at once?
It seems like the type of question to be easily googled, and yet google is now no longer a functional website anymore, so I’m SOL on that front.
Side note: anyone with tips on how to distinguish between fungal, insect, bacterial, and fungal damage, in a very basic layman’s way, please do advise.
Thank you!

Excellent question. I don’t have an answer, but I have a related dilemma: We’re facing extreme drought in much of Central Texas now in October which is causing stress in many deciduous shrubs and trees…just as some of our plants would be showing “Fall colors”–and in some cases I’m hard pressed to tell which is happening.

@gcwarbler AFAIK this could be a complicated question, as similar physiological mechanisms might be involved in both fall colours and drought stress

When iNat offered us a new annotation for leaf colour. Green or not. Not includes both fall and drought - which I find, odd.
