Apple Chlorotic Leaf Spot Virus (Aclsv) Status In Turkey And Sensitive Detection Using Advanced Techniques, Çi̇ğdem Ulubaş Serçe, Fi̇li̇z Ertunç
Turkish Journal of Agriculture and Forestry
The prevalence of apple chlorotic leaf spot virus (ACLSV) was investigated in all the main stone fruit growing areas of Turkey except for East Anatolia. Three hundred and sixty-nine plant samples showing virus related symptoms were collected from sweet and sour cherry, peach, nectarine, apricot and plum trees. All samples were tested using DAS-ELISA and reverse transcription-polymerase chain reaction (RT-PCR). Thirteen samples were detected as infected with ACLSV using ELISA while RT-PCR revealed 51 positive samples. The highest ACLSV incidence was in Bursa (64%), followed by Yalova (20.51%), Burdur (18.18%), Amasya (13.43%), Afyon (12.07%), Isparta (6.25%), Çanakkale (4.76%) and İzmir …

Turkish Journal of Agriculture and Forestry
The potential of the predatory mite Phytoseiulus persimilis (Acarina: Phytoseiidae) to control the carmine spider mite Tetranychus cinnabarinus (Acarina: Tetranychidae) on strawberries (cv. ´Camarosa`) grown under plastic tunnels was investigated in 2 fields during the 2001 and 2002 growing seasons in Aydın, Turkey. Three study plots, grower's practice, chemical control and biological control, were established. The population of T. cinnabarinus was controlled in the grower's practice plots by using 1 or 2 acaricide applications. However, it was suppressed with only 1 acaricide application in the chemical control plots at a population level below economic threshold levels. When the pest population …

The hazelnut is an important product in Turkey's economy as it is an important source of income for a large number of family farms and makes up around 75% of world production and 20% of total agricultural exports from Turkey. Hazelnut production has increased in recent years along with high levels of storage and expansion of planted areas from traditional steep lands to flat lands, where alternative cropping is possible. The aim of this study was to determine the major causes of these problems using an econometric model of Turkey's hazelnut sector. Estimation results of the model comply with economic …
