Gidul Nachrim-Produce of a gentile grown in Israel:
It is disputed amongst the Poskim as to the Kedusha status of products grown in Gentile owned lands within Eretz Yisrael. Some Poskim rule that fruits grown by a gentile in Eretz Yisrael do not have a status of Shemitah produce, as gentile removes the holiness from the land. Others rule that even produce grown by a gentile retains the holiness of Shemitah and hence all Shemitah regulations apply to their produce. Practically the vintage custom of Jerusalem and other communities in Eretz Yisrael follows the first opinion that it does not contain Kedushas Sheviis.
 See Minchas Yerushalayim p. 74 and 137
