Environmental factors can affect the look—and sometimes the flavor—of developing tomato fruits. Because these problems are not caused by disease organisms, there are no pesticide recommendations for prevention or management.
This 4-page publication briefly covers blossom end rot, blotchy ripening, catfacing, growth cracks, puffiness, and sunscald. For information about additional problems, please refer to Extension publication Tomato Disorder: Post-Harvest Fruit Diseases (A3799).
