Description
Transmitted by aphids, it is one of the most widespread potyvirus infections in United Kingdom stocks. The infection is referred to as late season yellows disease, coming on after flowering, hence 'late', with chlorotic streaks of leaves and stem that are sharply defined and pale green to yellow. The flowers are not affected. It is not transmitted to other genera. [2]
