Answer Posted / subhash singh, m.sc. ag., gbpu
Alternaria solani is the causative agent for early blight
of potato.
Symptoms: First, oval or angular dark brown to
black "target" spots appear on leaflets. Usually a narrow
chlorotic zone is found around the spot which fades into
the normal green. Lowest, oldest leaves are infected first,
and they droop and dry as the disease progresses. If spots
are numerous, they kill leaves and consequently may reduce
yield
Late blight of potato
Causative Agent: Phytophthora infestans
The disease is first seen as damp areas on the lower leaves
of plants that may fuse to form a large brown area of dead
or damaged tissue. The pathogen grows out from the leaves
on the lower surfaces of the leaves where it is seen as a
white downy mass. The disease is at most aggressive under
damp conditions and will rapidly kill all the aerial parts
of a plant. A cycle of infection to sporulation can take as
little as four days. If there is a dry period, the disease
pauses but will resume when the weather turns damp again.
Infected potato tubers show surface damage only, but the
damage may allow other microorganisms to enter the tuber
and destroy it. The rot can be so severe that entire fields
may smell of rotting vegetation
