Important
viruses mainly caused “pepper yellowing disease” in field-grown and
greenhouse-grown peppers, their hosts and vectors were investigated in Hatay
province of Turkey. Young
shoot, leaf and fruit samples taken from suspected pepper plants and weeds were
investigated by DAS-ELISA and biological indexing. Virus infections caused chlorosis or yellowing symptoms were
mostly observed in pepper growing areas of Iskenderun and Samandağ districts in
Hatay. PVY infection was determined as the most common in pepper growing areas
in Hatay (13.8%). PVY (Potato virus Y) was followed by the CMV
(Cucumber mosaic virus) (5.5%),
respectively. Mixed infections
caused by double, triple and multiple viruses including CMV, BWYC (Beet western yellows virus),
PLRV (Potato leaf roll virus), PVX (Potato X virus), PVY, ToMV (Tomato
mosaic virus) and TSWV (Tomato
spotted wilt virus) were identified in pepper plants with low rates. Amaranthus retroflexus, Chenopodium quinoa,
Convolvulus arvensis, Malva sylvestris, Physalis angulata, Mercurialis
annua, Solanum nigrum, Sonchus oleraceus and Xhanthium strumarium were commonly found in pepper fields. A few
pepper plants were found to be infested by dodder (Cuscuta campestris) and Orobanche
ramosa. Portulaca
oleracea, Urtica dioica and Plantago
major were
observed in pepper grown under greenhouse conditions.
Orobanche
ramosa was also determined in two pepper greenhouses. Amaranthus retroflexus (28.5%), M. sylvestris (40.0%), S. nigrum (30.0%) and S.
oleraceus (33.3%) were found to be infected with AMV; A. retroflexus (40.0%), M. sylvestris
(57.1%), P. angulata (16.,6%)
and S. nigrum (50%) samples were
found to be infected with CMV, M. sylvestris
(20.0%), M. annua (41.6%)
and P. angulata (83.3%) samples were
found in PVY; TSWV was detected in P.
major (25.0%) samples. Other viruses
such as Beet curly top virus (BCTV) or
begomoviruses and phytoplasmas which were
not tested in this study were thought to be also causal agents of “pepper
yellowing disease” in pepper growing areas in Hatay-Turkey.
