white fungal/pest growth on lemon plant
This white mass seems to be spreading along the stem of my lemon sapling. I doubt it is a pest, so is it mildew or some fungus? How do I get rid of it quickly?
The monsoon is approaching where I live, so the rains could spike the humidity and make it worse if this is some mold.
