Sugar-like substance on leaves? Heads up!
Just thought I'd post this as a precaution.
I recently noticed what looks like a very fine white sugar on my tomato leaves. Further inspection revealed an infestation of tomato psyllids. Luckily I was able to remove the infected leaves while the infestation was rather mild, but there were many on each leaf.
If you see the fine sugar on your leaves, they are hiding nearby, ususually on the underside of the leaves. The eggs are orange and very tiny, ususally along the edges of the leaves.
