What's eating my purple majesty potato?
Colorado potato beetle (Leptinotarsa decemlineata)
Signs: Rapid total defoliation by striped adults and bright-orange larvae; plants fail to form tubers if hit early
Control: Hand-pick all life stages; apply spinosad or Bt tenebrionis early; rotate fields/beds every season
Peach-potato aphid (Myzus persicae)
Signs: Yellowing, curled leaves; mosaic virus and potato leafroll virus spread via aphid feeding reducing yield
Control: Use certified virus-free seed tubers; spray insecticidal soap; introduce parasitic wasps; remove heavily infested shoots
Wireworms (Agriotes spp.)
Signs: Click-beetle larvae bore into developing tubers leaving tunnels that allow secondary rots to enter
Control: Avoid newly turned sod; pre-plant bait stations (carrot pieces) to detect levels; apply Steinernema nematodes

Purple Majesty Potato pests — FAQ
What is eating my purple majesty potato?
Purple Majesty potato faces the same solanaceous pest trio as other varieties: Colorado potato beetle decimates foliage, aphids vector devastating viruses, and wireworms ruin tubers. Its purple pigmentation (anthocyanins) offers no pest resistance. Start with certified seed, rotate beds annually, and scout daily during the beetle's peak flight in early summer.
