What's eating my all blue potato?

All Blue potato is hit by the same major solanaceous pests as other varieties: Colorado potato beetle strips foliage, peach-potato aphid transmits viruses that devastate yield, and wireworms or slugs tunnel the tubers. Its blue-purple skin offers no pest deterrence. Rotate beds, start from certified stock, and scout leaves daily during early summer.

Complete defoliation by adults and orange-red larvae; yield loss proportional to timing of attack Hand-pick egg masses (yellow clusters on leaf undersides) and adults; spray spinosad at first instar larvae; rotate location

Curled leaves, sticky deposits, sooty mould; potato leafroll and mosaic viruses spread plant to plant Use certified seed tubers; apply neem oil or insecticidal soap; destroy infected plants promptly

Cylindrical tunnels into tubers ruining the flesh and allowing fungal rots to follow Avoid ground previously under grass; use Steinernema feltiae nematodes in late summer; bait traps early spring
