Which type of pesticide is specifically designed to target weeds?

Herbicides are specifically formulated to control and eliminate unwanted plants, commonly referred to as weeds. They work by targeting particular physiological functions or processes in the plants that they are designed to kill without affecting desirable plants. For example, some herbicides may inhibit photosynthesis, while others disrupt the growth processes of the target weeds.

In contrast, insecticides are designed to manage insect pests, fungicides target fungal diseases, and pheromones are used primarily for pest monitoring and control through the use of chemical signals. Since herbicides are tailored to deal with unwanted vegetation, choosing herbicide as the answer directly addresses the need for weed control in lawn and ornamental applications.
