Pest identification
What's eating my cardamom?
Thrips (Scirtothrips cardamomi and others)
Signs: Silver-white streaking and speckling on leaves and flower/capsule surfaces; distorted new growth; capsules may be scarred and malformed.
Control: Remove and destroy heavily infested plant parts; introduce predatory mites (Amblyseius cucumeris) in greenhouse settings; insecticidal soap or spinosad spray; maintain humidity.
Root-knot nematodes (Meloidogyne spp.)
Signs: Plants grow slowly with yellowing foliage; galls (knots) visible on roots when dug; yield severely reduced in warm climates.
Control: Plant in well-drained, organically rich soil; rotate planting sites; incorporate neem cake into soil; use certified nematode-free planting stock.
Spider mites (Tetranychus urticae)
Signs: Fine stippling on leaf surfaces, bronzing in hot dry conditions; fine webbing on undersides.
Control: Increase humidity; spray with neem oil or insecticidal soap; introduce predatory mites; avoid drought stress.
Mealybugs
Signs: White cottony masses at leaf axils and along rhizomes; plant vigor weakens; sooty mold follows.
Control: Wipe colonies with alcohol-soaked cotton; neem oil drench; insecticidal soap spray repeated at 7-day intervals.

Cardamom pests — FAQ
What is eating my cardamom?
Cardamom grown outdoors or under glass faces thrips as its most damaging pest — they rasp leaf and capsule surfaces causing silvery streaking. Root-knot nematodes are a serious soil pest in warm climates. In indoor or greenhouse settings, spider mites and mealybugs also appear. Capsule borers threaten fruiting plants in tropical production.
