Carbaryl is widely used as an insecticide in agriculture to protect crops from a variety of pests, including beetles, moths, and aphids. It is applied to fruits, vegetables, cotton, and ornamental plants to prevent damage and improve yield. In addition to agricultural use, it is employed in home gardens and for pest control in public spaces like parks and golf courses. Carbaryl is also utilized in veterinary medicine to control fleas and ticks on pets and livestock. Its effectiveness in managing pest populations makes it a valuable tool in both commercial and residential settings. However, its use is regulated in some regions due to environmental and health concerns.
