Ginger leaf roller
Green caterpillars with a black head fold the leaves lengthwise and feed hidden inside the rolls, and heavy attacks strip the leaves.

Where the damage shows
When to act
Check the clumps weekly. Pick off rolled leaves by hand. Spray only when more than 1 in 4 leaves are rolled with live larvae.
What to spray
Active ingredients only, never brands. The IRAC group tells how it works: switch to a different group next time, so the pest does not learn to survive it. Spray only when the damage is worth the cost, and only with products registered with the Fertilizer and Pesticide Authority for your crop. Follow the label. The Shopee and Lazada links only show who sells something with that active ingredient, not a recommendation of any seller or product.
On labels for it, but not advised
- Dimethoate: Made for sucking insects. Weak on caterpillars hidden in rolled leaves.
How to prevent it
- Pick off and crush rolled leaves with the larva inside.
- Keep weeds down around the beds and remove old leaves after harvest.
- Do not plant ginger or turmeric after one another in the same field.
Natural enemies and biological help
- Small wasps and spiders kill many larvae. Leave light attacks unsprayed.
