Larve mine into the tender leaves
in zig-zag manner and scrape
chlorophyll. Photosynthesis is
adversely affected, vitality is
reduced and there is an
appreciable reduction in yield.
Affected leaves of plants become
curled, wrinkled & gradually dry
up. Feeding cause flower or leaf
buds to abort or emerging leaves
to become distorted.
Small brown or yellow dotes on
the leaves of plant are most
easily observed sign of a mite
infestation. Severely infested
plant leaves become discolored,
producing an unthrifty gray or
bronze look to the plant.
Leaves, buds and stem are cover
with white powdery coating.
Affect leaves curl upwards
Failure of seedling emergence
from the soil results in patchy
appearance of seedlings stand in
the nursery in early stages of
growth. (Pre-emergence) toppling
over of infected seedlings at any
time after their emergence from
the soil resulting in mortality of
the seedlings.
Root nodulation/galls on the
roots.
Yellowing and drooping of plants,
wilting of leaves, stunting and
browning of vascular system.
The disease is characterized by
the appearance of brown dead
areas on leaves, which initially
appear as faded green patches
and later turn into brownish black
lesions spreading rapidly during
wet weather. Within 3-4 days of
wet weather whole plant may get
blighted.

pale brown, concentric rings
resembling slightly the marking
on a buck eye.

Tomato
The spots appear as small, water
soaked, more or less circular
spots in outline and show definite
brown colored margins with grey
centers.
