Pest identification
What's eating my kiwano?
Aphids
Signs: Dense clusters on shoot tips and leaf undersides; leaves curl and yellow; sticky honeydew attracts sooty mold.
Control: Blast off with a strong jet of water; spray with insecticidal soap or neem oil; introduce lacewings or ladybugs as biological control.
Cucumber beetles (striped & spotted)
Signs: Adults chew ragged holes in leaves and flowers; larvae feed on roots; they transmit bacterial wilt which causes sudden vine collapse.
Control: Use yellow sticky traps; cover plants with row cover until flowering; apply kaolin clay; remove and destroy affected vines quickly.
Spider mites
Signs: Bronze stippling across leaves in hot, dry weather; fine webbing on undersides; leaves dry out and drop prematurely.
Control: Maintain consistent irrigation and humidity; spray leaf undersides with water or insecticidal soap; apply predatory mites (Phytoseiulus persimilis) in greenhouse settings.
Slugs and snails
Signs: Irregular holes in young leaves and seedlings, especially in cool damp weather; silvery slime trails left behind.
Control: Apply iron phosphate pellets around the base; use copper tape barriers in raised beds; hand-pick at night; keep the area free of debris.
