Hail Injury on Grapes
Return to Abiotic Disorders
Hail injury damages canes, foliage, and fruit. Foliage becomes shredded and may be torn completely from the canopy. Injured shoots can have dents and broken epidermis. Bruises, cracks, and scarring develop on fruit; physical damage alone can cause significant berry quality and crop loss. Wounded tissues also become potential sites for infection by disease-causing organisms.
