What's eating my crystal apple cucumber?

Crystal Apple is an outdoor cucumber susceptible to aphids vectoring cucumber mosaic virus — the biggest risk to this open-pollinated variety. Slugs attack seedlings. Powdery mildew affects leaves late in the season. Spider mites can build up in hot, dry summers. Good airflow, consistent watering, and early aphid control protect the unique round fruit.

Aphid colonies on shoot tips; CMV causes yellow-green mosaic mottling on leaves, stunted growth, and misshapen or bitter fruit — plants may need removing entirely Inspect plants weekly from June; blast aphids off with water; neem or insecticidal soap spray; remove virus-symptomatic plants immediately in a bag — do not compost; reflective mulch deters incoming winged aphids

Seedlings and young transplants eaten at ground level; holes and trails on low-hanging or ground-contact fruit Harden off plants fully before transplanting; ferric phosphate pellets; raise containers or train plants off the ground; hand-pick at night

Fine stippling on leaves turning bronze; webbing on undersides in hot, dry spells; severe attacks cause defoliation and poor fruit set Mist foliage in dry weather; maintain consistent soil moisture; neem oil spray; avoid dusty growing conditions that promote mites

White powdery patches on upper leaf surface from midsummer onward; leaves yellow and die back early, shortening the harvest window Water at base rather than overhead; ensure good air circulation between plants; remove infected leaves; potassium bicarbonate or neem spray at first signs
