Biopesticides are natural or biologically derived agents used to manage pests, diseases, and weeds in agriculture. They include microorganisms (e.g., bacteria, fungi, viruses), natural substances (e.g., plant extracts and pheromones), or genetically engineered organisms. Biopesticides are eco-friendly, target￾specific, and often less harmful to humans and beneficial species compared to synthetic chemical pesticides, promoting sustainable pest control.
