Symptoms at stem end. Catfacing symptoms are associated with adverse growing conditions during blossoming; the adverse conditions result in poor pollination, which leads to irregularly shaped fruit. Catface symptoms are most often seen in large-fruited, fresh market varieties (although other varieties can also be affected) and are associated with disturbances in flower production such as low temperature injury 3 weeks before flowers are mature, especially in early plantings, but also with injury from growth regulators such as 2,4-d. Pruning and high nitrogen can also aggravate the problem.
