Common Diseases of Tomato Plants

Page 14

Cat-Facing Description The term cat-facing refers to tomatoes that are generally distorted, misshapen, or dimpled. The damage usually results from injuries that cause the fruit’s blossom scar to become enlarged or perforated. Causal factors include high nitrogen levels, temperature extremes or fluctuations during flowering, excessive pruning, or poor pollination. Feeding by piercing-sucking insects such as stink bugs or lygus bugs damage the tomato skin, also causing cat-facing symptoms.

Management Growing conditions that best support plant growth and good pest management can reduce cat-facing. Floating row covers may reduce cat-facing if insects are causing the damage. Avoid excessive nitrogen, prune properly, and select cultivars that are less prone to cat-facing (some heirloom tomato varieties are more susceptible). Tomatoes with cat-facing are still edible but less likely to be marketable.
