What is the difference between early blight and late blight?
The potato and tomato plants that are members of the Solanaceae family are susceptible to two different illnesses known as late blight and early blight.

- When there is a high level of humidity, the undersides of the leaves, as well as the stems and petioles, develop a unique white cottony sporulation.
- Plants that have been infected with late blight may give off an unpleasant stench that is similar to that of decomposition.
