If the lesions get massive, they dry out and flatten, turning black and leathery. It begins when the fruits are mature inexperienced and beginning to ripen.
Often, this occurs to the primary tomatoes produced through the season, whereas these from afterward might be environment friendly. That is notably true for indeterminate varieties, since they produce tomatoes till the tip of the season.
