tomatoes and peppers grown in the field or greenhouse (Brown et al., 2010) in Central
America.
No universally accepted name exists for this disease on tomatoes, as illustrated
by the use of different names: tomato vein-greening in Arizona (Brown et al., 2010),
permanent yellowing in Mexico (Munyaneza et al., 2009b) and Paratrioza disease in
Guatemala. At least from our observations in Guatemala several symptoms are
notable: flower abortion, purpling of the leaf margins, stem thickening, yellowing of
younger leaves, and stunting. An internet search reveals that there is a substantial
number of sources using „permanente del tomate‟ or permanent yellowing disease of
tomato. Thus, it is proposed that this diseased be named Liberibacter permanente del
tomate or Liberibacter yellowing disease of tomato. This would distinguish this disease
from psyllid yellows (Brown et al., 2010).
