Plant Fungicides

Airborne '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. Some fungi live in the soil and enter roots. They can either block the water-conducting cells or kill them, causing the plant to wilt. In many cases the plant is seriously damaged. Plant Fungicides kill the fungus through a biochemical interaction on the spores.
