Synthetic pesticides are man-made chemicals designed to control pests that harm crops, plants, and livestock. They work by targeting specific biological processes in insects, weeds, and fungi, helping to protect agricultural yields and improve food production. Common types include insecticides, herbicides, and fungicides. These pesticides are often more effective and longer-lasting than natural alternatives, but they can also pose risks to human health and the environment. Concerns include potential toxicity to non-target species, the development of pesticide-resistant pests, and contamination of soil and water. Proper usage and regulation are essential to minimize these risks.
