How is a "pest" defined in the context of pesticides?

In the context of pesticides, a "pest" is defined as an organism that is considered harmful or troublesome. This definition encompasses a variety of organisms that can negatively impact human activities, particularly in agriculture, such as insects, weeds, fungi, and rodents. Pests can cause damage to crops, spread diseases, and disrupt ecosystems, leading to economic losses and threats to food security.

Understanding this definition is crucial when discussing pest management strategies, as it highlights the need for effective control methods to protect crops and public health. The emphasis is on identifying and managing organisms that pose a threat rather than focusing on those that may be beneficial or neutral to the environment.
