Which of the following is a type of plant disease?

Blight

The correct answer is Option (2) – Blight

Blight is a type of plant disease.

Blight refers to a rapid and severe discoloration, browning, wilting, and death of plant tissues, usually caused by various pathogenic microorganisms such as bacteria, fungi, or oomycetes. These pathogens can infect different parts of the plant, including leaves, stems, fruits, and roots, leading to significant damage to crops and other vegetation.

The term "blight" is commonly used to describe specific diseases affecting various plants, such as late blight in potatoes and tomatoes, early blight in tomatoes, fire blight in pome fruits (such as apples and pears), and oak wilt in oak trees. These diseases can cause substantial economic losses in agriculture and forestry by reducing yields, impairing quality, and even killing entire plants or trees.
