Seeing soil like dark spots on my potato leaves and curry leaves

Potato    None Given

In the last 1 week, I have been noticing fine soil like dark spots on my potato plants and curry leaves plant. I was thinking it to be soiled leaves and never bothered much but when I tried to clean the leaves it seems its not soil and something else.

I think it may be black sooty mold (fungal growth). Usually the sooty mold can be seen on leaves, stems, and/or fruit of plants. The sap sucking insects like whiteflies, mealybugs, scale, aphids etc. secret the sugary substance (honeydew) on infected plants which helps in developing sooty mold. Although sooty molds don’t infect plants but causes indirect damage by inhibiting sunlight penetration and photosynthesis. So check your plants for any insect infestation.

It can be controlled by spraying starch or wash it off with warm soapy water.
