Agricultural chemicals are substances used to improve crop growth, protect plants from pests and diseases, and enhance soil fertility. These include fertilizers, pesticides, herbicides, and fungicides, all of which help farmers increase crop yields, manage weeds, and safeguard crops from harmful organisms. By using agricultural chemicals, farmers can ensure healthier plants, higher-quality produce, and more efficient farming practices. When applied responsibly, these chemicals support sustainable agriculture and contribute to global food security.
