Corn (Zea mays) is a major crop grown in many parts of the world. It is a staple food for millions of people, and it is also used to produce a variety of other products, such as corn syrup, ethanol, and animal feed. Corn plants are susceptible to a number of diseases and pests, and they can also be affected by environmental factors such as drought and flooding. When corn plants are stressed, they may begin to yellow and brown. This can lead to reduced yields and even crop failure.
