Pest identification
What's eating my xanthosoma sagittifolium?
Aphids
Signs: Dense colonies on leaf undersides and petioles; honeydew leads to sooty mold and reduced plant vigor
Control: Knock off with a water blast; apply insecticidal soap or neem oil; attract beneficial insects
Spider mites
Signs: Fine stippling and webbing on leaf undersides; leaves bronze and dry at margins in hot, dry conditions
Control: Increase moisture and humidity; apply neem oil or insecticidal soap; repeat every 5–7 days
Slugs and snails
Signs: Ragged holes chewed through large leaves overnight; slime trails confirm presence on foliage and soil
Control: Apply iron-phosphate bait around plants; hand-pick after dark; clear debris sheltering slugs during the day
Wireworms
Signs: Tunneling damage inside edible corms reduces quality and allows secondary rot pathogens to enter
Control: Rotate crops each season; harvest corms promptly; bait traps using carrot or potato chunks buried shallowly
