Blight is a rapid and complete chlorosis, browning, then death of plant tissues such as leaves, branches, twigs, or floral organs. [1] Accordingly, many diseases that primarily exhibit this symptom are called blights.
Blighty is commonly used as a term of endearment by the expatriate British community or those on holiday to refer to home. In Hobson-Jobson, an 1886 historical dictionary of Anglo-Indian words, Henry Yule and Arthur Coke Burnell explained that the word came to be used in British India for several things the British had brought into the country, such as the tomato and soda water.

Phytophthora (from Greek φυτόν (phytón), "plant" and φθορά (phthorá), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species cause economic losses on crops worldwide, as well as environmental damage in natural ecosystems.
Removing blighted trees to control the disease was first attempted when the blight was discovered, but this proved to be an ineffective solution. Scientists then set out to introduce a hyperparasitic hypovirus into the chestnut blight fungus. The trees infected with virus-treated fungus responded immediately and began to heal over their cankers.
In the early 1800s, a strain of potato blight (Phytophthora infestans) known as HERB-1 began to spread in the Americas, especially Central and North America, destroying many crops. The blight spread to Europe in the 1840s where, because of an extreme lack of genetic diversity, the potato crops were even more susceptible. In Northern Europe ...
