What's eating my atlantic giant pumpkin?

Atlantic Giant pumpkins (Cucurbita maxima) are prized by competitive growers and attract big appetites. Squash vine borers can kill vines before the fruit matures. Squash bugs colonize stems in large numbers. Cucumber beetles spread bacterial wilt. Deer, groundhogs, and — for mature giant fruits — raccoons all become serious problems. Powdery mildew is universal late-season.

Frass at stem base; sudden mid-season vine wilt; giant pumpkin can die weeks before harvest if main vine is girdled. Wrap the main vine stem with foil or row cover fabric for its entire length; bury vine at multiple nodes to create backup root systems; inject Bt at borer entry points.

Large colonies suck sap from stems; leaves die back; nymphs aggregate near the crown and can kill young vines completely. Intense daily egg-mass removal; hand-pick adults; kaolin clay on stems; remove surrounding weed cover that shelters overwintering adults.

Beetles chew flowers and leaves; bacterial wilt causes irreversible plant collapse, threatening all the season's growth. Row cover until pollination is complete; monitor with yellow sticky traps; pyrethrin or spinosad spray for high populations.

Deer and groundhogs browse young vines; raccoons claw open and hollow out giant fruit as it softens near maturity. Electric fencing around the entire patch is the most effective barrier for all three; heavy wire caging around the developing fruit for raccoons.
