Plant diseases and treatment

Plant diseases cause great damage to crops every year. They may kill whole fields of cereal crops or root crops, or whole orchards of fruit trees. Some diseases affect the crops so that they are of low quality and poor yield. Plant diseases can cause famine by destroying important crops.

In Ireland, an epidemic of fungus blight destroyed the potato crop in 1845 and for several years afterwards there was widespread famine. Three-quarters of a million people starved to death.

Fungi attack many kinds of plants. Rusts and smuts are fungal diseases affecting cereals. Rye infected by a fungus called ergot may cause serious illness in anyone eating bread made from it. But ergot is also a source of useful drugs for controlling blood pressure. Bacteria and viruses attack plants as well as men and animals. Viruses produce mosaic disease, which affects fruit trees, tobacco, and other crops.
