This dataset reports the occurrence of an agricultural epidemic called "powdery mildew" in mango trees. The epidemic typically occurs in the third and fourth week of March, and hence outbreak status is known by the end of March of a given year. Typically, two weather predictors $($maximum temperature and relative humidity$)$ are used to forecast an outbreak.
