Fungi can infect plants in several ways: 1) Some fungi digest dead materials like wood and leaves, while others form beneficial relationships with living plants. 2) Pathogenic fungi infect plants by entering through openings like stomata or making holes in the epidermis. 3) Once inside, they either poison plant cells before absorbing nutrients or simply steal nutrients from living cells. Fungal spores can infect plants through airborne transmission to leaves or through the soil into roots. These pathogenic fungi threaten crops.

1. HOW DO FUNGI ATTACKS PLANTS
• Fungi can't make their own food:
1)Some fungi can digest things like dead leaves and wood.
2)Set up mutually beneficial relationships with living plants.
3)Attack other plants and steal food from them.
• These 'pathogenic' or disease-causing fungi get inside the plant either by making
a hole in its skin (epidermis), or by growing in through the plant's breathing
holes (stomata).
• Then they either poison and kill the plant cells before absorbing food from them,
or simply steal nutrients from the living cells.
• The spores of fungi come through: AIR -attack the leaf.
SOIL -enter the roots.
• So such pathogenic fungi can threaten our crops.

2. Effect Of Fungus on Plants
• Some fungal infections that affect the
roots and barks of the plants.
• One such fungi is Canker Fungi.
• It is found on woody trees and is
notorious for causing localized damage
to the barks of trees.

3. Effect Of Fungus on Plants
• It is a disease caused by Colletotrichum
or Gloeosporium fungi
• Occur in warm and humid areas.
• Shrunken kind of spots of different colors
are observed on the fruits, flowers, stems,
and leaves.
• These spots gradually expand and cause
the plant to die.

4. Effect Of Fungus on Plants
• This disease affects the stems, leaves,
seeds, and fruits of the plant.
• It can be identified if spots of brown,
yellow, red, or orange colors are seen.
• It may reduce the vigor of the plant. It is
caused by pathogenic fungi.

5. Effect Of Fungus on Plants
• Ustilago maydis is a fungus that affects
corn and sugarcane plants.
• Blisters develop on the affected parts of
the plant and it gets discolored as well.
• The kernels become huge, they swell up,
and the whole plant and fruit are slowly
destroyed.

6. • This type is generally seen in the rainy or
damp areas, mostly affecting timber.
• It is caused by Coniophora puteana or
Poria vaillantii.
• Wet rot mostly results in decaying of the
plant.

7. Effect Of Fungus on Plants
• Alternaria solani is the fungal pathogen
that causes early blight disease in
potatoes and tomatoes.
• It destroys the fruit of the plant and
affects the life as well.
• The leaves and fruits turn yellow or
brown and then drop off from the plant.

8. • This fungal disease gets its name because
it causes the plant (it infects) to wilt.
• Fungal invasion starts in the roots
->stem ->plugs of the vascular system of
the plant.
• Fusarium wilt and Verticillium wilt :
plant wilting that affect many plants, like
cotton, potato, tomatoes, tobacco, and so
on.
