Turmeric: Diseases and Symptoms

Turmeric (Curcuma longa) is one of the most valuable spice crops grown across tropical and subtropical regions of India and the world. Apart from its culinary use, turmeric holds immense medicinal value owing to curcumin — a compound known for its anti-inflammatory, antioxidant, and antimicrobial properties. However, like many other crops, turmeric faces several diseases that can drastically affect its yield and quality.

To ensure sustainable production, understanding the major diseases of turmeric, their symptoms, and effective management practices is essential. Integrated Pest Management (IPM) techniques play a vital role in maintaining crop health while minimizing dependence on chemicals.
