The plant pathogen causes a yellow leaf disorder in solanaceous crops including tomatoes. [1] ToCV is transmissible by whiteflies, phloem-limited and causes symptoms of interveinal chlorosis followed by necrosis in the tomato plants leaves resulting in a reduced fruit yield. [1] ToCV has a wide range of hosts such as pepper and potato. [4]

The infected plants in Israel were cultivars that carried the Tm-2 2 resistance gene which confers diseases resistance against some other tobamoviruses. [4] ToBRFV has also been confirmed from Palestine [5] with symptoms first noted in Autumn 2018. [6] Tomato brown rugose fruit virus spread rapidly to other
