Since 2016, the TBRFV virus has caused serious damage to tomatoes greenhouses in Israel. In the 2019-20 season, a trial was conducted in which foliar feeding was incorporated into plant protection sprays. The purpose of the foliar feeding was to overcome the damage caused by a virus that had severely damaged the previous season's yield. It was assumed that foliar feeding would reduce the impact of damage to the roots and transport systems of the plant and would reduce yield reduction.
