Catface - Tomato
"Catface” is a term for describing misshapen fruit with scars and holes on blossom end. Possible causes are cold weather with night temperatures 58 F or lower at flowering time, high nitrogen levels, and herbicide injury. The tomato varieties with very large fruits are more susceptible.
Avoid setting transplants too early in the season, grow cat-face resistant varieties, and avoid injury by 2,4-D herbicide.
