CHEMICAL PRODUCTS

Agricultural chemicals — also known as agrochemicals — play a major role in modern farming by helping to increase crop yields, protect plants, and improve food quality. Here’s a breakdown of their main roles:
🌾 1. Fertilizers Purpose: Supply essential nutrients (like nitrogen, phosphorus, and potassium) to crops. Role: Promote healthy plant growth Increase yield and quality of produce Replenish soil nutrients depleted by previous crops Examples: Urea, ammonium nitrate, superphosphate, potash.
🐛 2. Pesticides Purpose: Protect crops from pests, weeds, and diseases. Types and roles: Insecticides: Kill harmful insects (e.g., mosquitoes, beetles) Herbicides: Control or kill weeds that compete with crops Fungicides: Prevent fungal diseases like mildew or rust Rodenticides: Control rats and mice in storage or fields Example: DDT (historical), glyphosate, malathion, mancozeb.
🌱 3. Plant Growth Regulators (PGRs) Purpose: Influence the physiological processes of plants. Role: Stimulate or inhibit growth Regulate flowering, fruiting, or ripening Improve plant resistance to stress Examples: Auxins, gibberellins, cytokinins, ethylene.
