Cardamom Pests & Their Biological Control: Complete Farmer Guide
ಹಂಚಿ
Insect pests are one of the major reasons for reduced cardamom yield and poor capsule quality. They damage leaves, shoots, flowers, roots, and capsules, leading to lower productivity and reduced market value.
Biological pest management uses beneficial fungi and bacteria to control pests naturally. Products like Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii provide effective control while preserving beneficial insects and reducing chemical pesticide use.
