Regular monitoring of crops for pests and diseases is important because early detection allows for timely intervention, preventing widespread damage and significant yield losses. It helps in identifying the specific pest or disease, enabling targeted and effective treatment, thereby minimizing the use of broad-spectrum chemicals. Upon detecting an infestation or infection, a farmer should: 1) Identify the pest/disease accurately. 2) Isolate affected plants if possible to prevent spread. 3) Apply appropriate control measures (e.g., specific pesticides, biological agents, or removal of infected plants). 4) Consult agricultural experts for guidance. 5) Implement preventive measures for future crops.
