Basil – Gross Growth on Leaf Base
I never saw this before - on my basil plants, near the new shoots on the top of the plant, there is a mucus like substance surrounding the base of the leaves and around the stem. It is thick and drippy. I cut all the infected tips off - not to be gross, but it has the appearance and texture of 'snot' although milky white in color. I can't find anything online or in my books - and I am a Master Gardener in NJ! What is it?
