3. DISEASE CYCLE

4. DISEASE CYCLE
The disease cycle begins with the infection by a
microscopic spore. This spore enters the plant via a natural
opening on the underside of the leaf. After entering, the
spore invades other cells to obtain nutrients. This eventually
kills the cells while producing new spores.
These new spores are forced out through the leaf openings.
Here, they are dislodged primarily by rain but also by wind,
animals and people. This begins the infection anew. This
process takes about 4 to 7 weeks.
A single spore can produce four to six generations. The
initial single infection generates an exponential increase of
tens of thousands of spores.
