Cardamom Diseases & Their Biological Control: Complete Farmer Guide
ಹಂಚಿ
Cardamom is affected by several fungal and soil-borne diseases that reduce plant growth, flowering, capsule production, and overall yield. Biological disease management helps control these diseases naturally while improving soil health and plant immunity.
Regular application of Trichoderma, Pseudomonas fluorescens, and Bacillus subtilis protects the root zone, suppresses harmful pathogens, and promotes healthy plant growth.
