True or False: All pesticides are designed to kill insects.

The statement that all pesticides are designed to kill insects is false because pesticides encompass a wide variety of substances used to control pests, which include not only insects but also weeds, fungi, bacteria, and other organisms. There are herbicides specifically formulated to target and eliminate unwanted plants, fungicides intended to combat fungal diseases, and rodenticides designed to control rodent populations. This broader classification means that while some pesticides are indeed focused on insects, many others are developed for different types of pest control, thereby making the assertion incorrect. Understanding the diverse functions of various pesticide classifications is essential for effective pest management in agriculture and public health.
