It sounds like you’re unsure whether your moong crop has a disease or a pest problem. In moong, most visible damage is actually caused by insects (pests), not diseases. Here’s a simple way to identify what’s happening:

If you see insects or damage like holes
Cause: Pest attack
Examples:
Holes in pods → Pod borer
Small insects under leaves → Aphids / Whitefly
Treatment: Insecticides like Emamectin Benzoate or Imidacloprid
If there are no insects, but spots or color change
Cause: Disease (fungal/viral)
1. Yellow Mosaic Disease (very common)
Leaves turn yellow in patches (mosaic pattern)
Plant stops growing
Spread by whitefly
Control: Spray Imidacloprid to control whitefly
2. Leaf Spot
Brown/black spots on leaves
Leaves dry and fall
Control: Spray Carbendazim @ 1 g/litre
Simple rule to understand:
Insects visible → Pest problem
No insects, only spots/yellowing → Disease
