Sunflower Response to Hail Damage Total defoliation of young sunflower plants up to bud stage usually causes little yield loss if storm damage is minimal. Damage to the terminal bud will delay maturity, cause yield losses and production of multiple heads. Multiple heads do not yield well and may lodge or break easily. Stem bruises if severe can open plant to stalk diseases and possible lodging problems later in the season. Back to Hail Menu -
