The owner of the Sugar Tree brand, Kingsburg Orchards, has more than 100 products certified as kosher by the OU. All the ones I saw were whole fresh fruit like peaches and apples. And as you can see here, even though the OU is giving its hechsher to whole fresh fruit, the OU does not certify that fruit for Passover use.
