What's eating my german butterball potato?

German Butterball's creamy, buttery tubers are as attractive to soil pests as to cooks. Colorado potato beetle is the primary above-ground defoliator; wireworms and slugs damage tubers below. Aphids carry viruses. Voles in rural plots can tunnel to find tubers in autumn. Annual rotation and certified seed potatoes are non-negotiable starting points.

Yellow-and-black striped adults and brick-red larvae consume all leaf tissue rapidly, collapsing plant vigour Scout every 2–3 days; hand-pick; apply spinosad or Bt tenebrionis; rotate potatoes out of the bed each year

Virus vectoring causes leaf roll, chlorosis, and severely reduced tuber size even with low aphid numbers Start with certified virus-free seed; early-season insecticidal soap applications; eliminate solanaceous weeds nearby

Click beetle larvae bore neat tunnels into tubers; damage is discovered only at harvest Pre-season buried carrot bait traps; apply entomopathogenic nematodes (Steinernema feltiae) in August–September

Ragged cavities on tuber surface and into flesh; worst in heavy, wet soils and wet autumns Harvest promptly; ferric phosphate pellets; clay-breaker grit incorporation to improve drainage
