What's eating my cranberry 'stevens'?

Cranberry 'Stevens' is a leading commercial cultivar and carries the standard Vaccinium macrocarpon pest profile. Cranberry fruitworm is the most damaging pest, boring into developing berries. Blackheaded fireworm scorches shoot tips. Root weevils attack roots and notch leaf edges. Aphids colonize new growth in spring.

Prematurely red, dropped berries with a frass-plugged entry hole; larvae inside destroy fruit and move to adjacent berries Monitor with traps; apply Bt kurstaki at petal fall when eggs hatch; remove fallen fruit daily during harvest season to break the cycle.

Shoot tips webbed together, wilted, and brown; first generation damages new growth in spring, second damages shoot tips near fruit set Bt spray at bud break for first generation; repeat at fruit set for second; remove and destroy severely webbed tips to limit larval spread.

C-shaped notches on leaf margins from adult night feeding; root feeding by white grubs causes patchy wilting and dieback across the bed Beneficial nematodes to moist, warm soil in late summer; avoid overwatering that stresses roots; use sticky barriers to trap adults.
