  Cucurbit growing is affected negatively due to diseases caused by cucurbit viruses. In order to prevent this damage cucurbit viruses were identified by serologically. Due to this study, it is usually difficult to give definitive diagnosis based on symptoms but occasionally symptoms; are curling, wrinkling, spot mosaics, yellowing, shape deformation on leaves, smaller leaves than normal, buff-colored mosaics, observed on younger leaves of cucurbits and stunting , distortion and fruit deformation on the plants. After this, samples collected and taken to laboratory to determine the virus which caused this symptoms and DAS -ELISA tests were performed to determine CMV (Cucumber mosaic virus), CABYV (Cucurbit aphid borne yellow mosaic virus), ZYMV (Zucchini yellow mosaic virus), ToMV (Tomato mosaic virus), PMMV (Pepper mild mottle virus), PXV (Potato X virus), PYV (Potato Y virus) on the samples collected during July-August in 2004. At the end of this test out of 56 samples, 10 were found to be infected with one or more virus. As a result of this study 20 samples were infected by CMV and 22 samples were infected by ZYMV and 3 samples were infected by PVY.

  Pepper growing are negatively affected due to the diseases caused by pepper viruses in Gaziantep. In order to avoid the damage of pepper viruses, survey was performed in Nurdagi and Islahiye districts of Gaziantep province located in southeastern Anatolia. The symptoms observed on pepper plants in yards were consisted of mosaic and curling, vein clearing, chlorotic and necrotic spot, fruit and leaf deformations. In October 2001, samples were collected and performed biological and serological assays. TMV and CMV were determined as responsible agent of these symptoms. GAP (Güney-Dogu Anadolu Projesi = Southeastern Anatolia Project) is one of the most important agricultural recovery projects of Turkey. One of GAP inclusion is Gaziantep become a leading producer of pepper in Turkey. Although damage by viruses is yet very below threshold level, an effective control strategies should be now argued to avoid from possible virus problems in longer term.
