Their management requires integrated approaches including timely surveillance, speedy communication and rapid response. This surveillance system was developed in order to facilitate participation of extension offices (in provinces/districts) in the survey of wheat rust diseases and sharing of information quickly. The SMS based system was tested as a pilot tool in the Central Anatolia region of Turkey connecting 25 districts in 5 provinces through an SMS network during the rust development period (April-July) in 2013. The observations from 268 fields indicated that leaf rust and stem rust development was insignificant in the districts covered, occurring in only 2.3% and 1.9% of the fields respectively. Stripe rust prevalence was higher occurring in 44.8% of the fields. Of the inspected fields 2.5% had infected plant incidences between 15% and 40% requiring control measures. Using the SMS reports received from the extension officers, the system facilitated daily monitoring of rust development and exchange of observations among the relevant institutions, also sending out alert messages to designated authorities as necessary. The study demonstrated that the system can serve as a rapid surveillance and communication tool to facilitate timely decision making and rapid response to prevent wheat rust epidemics.

Dünya ekonomisinin %60 veya daha fazlasını üreterek biyo-ekonominin temelini oluşturan bu sistemlerin zaafa uğraması; bireylerin, toplulukların, ülkeler ve dünya ekonomisinin yanı sıra sosyal yaşamın sıkıntıya düşmesine ve büyük kayıpların yaşanmasına sebep olabilir. Biyolojik sistemlerin saldırıya uğraması ve biyolojik nitelikli bazı canlı veya ürünlerin silah olarak kullanılmasına tarih boyunca çok kez şahit olunmuştur. Günümüzde özel niteliklere sahip canlılar veya bunların bazı ürünlerinin, doğrudan insanlara veya birincil üretim ya da gıda üretim sistemlerine saldırı amaçlı olarak kullanılması mümkündür. Bu tür ajanların özellikleri, kullanımı, doğuracağı sonuçlar ve bunlardan korunmak için yapılması gerekenler, ilgili devlet otoriteleri için son derece önemlidir. Günümüzde konvansiyonel savaş taktiklerinin gelişip çeşitlendiği, terör saldırılarının da bu minvalde her geçen gün daha önem kazandığı açıkça gözlenmektedir. Tarım, orman, gıda ve doğal kaynakların sosyal hayatımızda ve ekonomimizdeki yeri ve önemi düşünüldüğünde "agroterörizmin" ele alınması gereken stratejik bir konu olduğu ve bu bağlamda alınması gereken çok sayıda tedbir olduğu aşikardır.

Weevil infestation was first detected in Turkey in summer 2005 in parks and gardens of Mersin province, along the Mediterreanean coast of Turkey. Following the discovery of the pest, destruction of infested plant material, prophylactic insecticide chemical treatments, as well as adult weevil trapping were carried out on palm plantations. Traps containing a commercial aggregation pheromone were hung on palm trees at a high density, in order to monitor the pest infestation and reduce the weevil population by mass trapping. A significant decrease in the number of trapped beetles and destruction of infested plant material was observed in 2009 and continued in the following years in several cities in Turkey. Therefore, it has been observed that mass trapping and curative pesticide applications have played a significant role in the suppression of R. ferrugineus populations in palm plantations.

PPV can be transmitted by vector aphids and may cause serious damage on fruits, leaves and flowers of Prunus species, especially on plum, apricot, and peach. Eradication of infected plants is one of the most recommended control methods of PPV in the world. The main objective of this study is to evaluate the National PPV survey and eradication program carried by the National Plant Health Authority between 2013 and 2018. During the six years of study, approximately 60.000 trees in 96.26% of Turkey were screened for PPV symptoms and 21.394 samples were collected from suspected plants from seven different fruit species. The samples were tested by ELISA (Enzyme Linked Immunosorbent Assay), and then ELISA questionable samples were verified by RT-PCR (Reverse Transcription Polymerase Chain Reaction). Based on the six years results, 2.718 samples from 161 locations were determined as PPV positive and the infection rate was calculated as 12.70%. During this study, 78.868 trees were eradicated. By the help of intensive monitoring and eradication program, PPV infection rate decreased from 35.72% to 7.47%. On the other hand, PPV infection was firstly recorded and eradicated in seven provinces (Aydın, Bolu, Denizli, Erzincan, Kırıkkale, Sivas, Samsun) which have been known as PPV-free before. This study showed that eradication is a very effective way to suppress PPV infection and spread. In conclusion, the national survey and eradication program should be operated nationwide and concentrated in nurseries.

Recently, MAPs are generally defined as plants that are used as drugs to prevent or cure diseases in order to maintain health and for other purposes. In general, MAPs used as food, herbal tea, supplementary food and medicine are obtained from nature or through cultivation. There is a worldwide trend of increased use MAPs, and although treating diseases with medicinal plants is more common in Far East countries, the trade of herbal medicinal products is a rising market in western societies. When we consider the trend of MAPs, Turkey is an important genetic center of many plant species thanks to its geographical location and genetic diversity. In addition, Turkey is a main partner of many countries that demand MAPs products for the world MAPs market. In this paper, the current situation of MAPs production in the world and Turkey are reviewed based on available data. In addition, this review touches upon Turkey's historical, cultural and economic situation as well as the subsidies for and research and development (R&D) activities focused on MAPs. Finally, the opportunities, potential, problems and outlook in this area are described in order to inform future decisions about MAPs.

Root diseases are the most difficult to tackle due to the complexity of phenotypic evaluation and the lack of resistant sources compared to other biotic stress factors. Soil-borne pathogens such as the root-lesion nematodes caused by the Pratylenchus species and crown rot caused by various Fusarium species are major wheat root diseases, causing substantial yield losses globally. A set of 189 advanced spring bread wheat lines obtained from the International Maize and Wheat Improvement Center (CIMMYT) were genotyped with 4056 single nucleotide polymorphisms (SNP) markers and screened for root-lesion nematodes and crown rot resistance. Population structure revealed that the genotypes could be divided into five subpopulations. Genome-Wide Association Studies were carried out for both resistances to Pratylenchus and Fusarium species. Based on our results, 11 different SNPs on chromosomes 1A, 1B, 2A, 3A...

The main objective of this study is to evaluate the National PPV survey and eradication program carried by the National Plant Health Authority between 2013 and 2018. During the six years of study, approximately 60.000 trees in 96.26% of Turkey were screened for PPV symptoms and 21.394 samples were collected from suspected plants from seven different fruit species. The samples were tested by ELISA (Enzyme Linked Immunosorbent Assay), and then ELISA questionable samples were verified by RT-PCR (Reverse Transcription Polymerase Chain Reaction). Based on the six years results, 2.718 samples from 161 locations were determined as PPV positive and the infection rate was calculated as 12.70%. During this study, 78.868 trees were eradicated. By the help of intensive monitoring and eradication program, PPV infection rate decreased from 35.72% to 7.47%. On the other hand, PPV infection was firstly recorded and eradicated in seven provinces (Aydın, Bolu, Denizli, Erzincan, Kırıkkale, Sivas, Samsun) which have been known as PPV-free before. This study showed that eradication is a very effective way to suppress PPV infection and spread. In conclusion, the national survey and eradication program should be operated nationwide and concentrated in nurseries.

Recently, MAPs are generally defined as plants that are used as drugs to prevent or cure diseases in order to maintain health and for other purposes. In general, MAPs used as food, herbal tea, supplementary food and medicine are obtained from nature or through cultivation. There is a worldwide trend of increased use MAPs, and although treating diseases with medicinal plants is more common in Far East countries, the trade of herbal medicinal products is a rising market in western societies. When we consider the trend of MAPs, Turkey is an important genetic center of many plant species thanks to its geographical location and genetic diversity. In addition, Turkey is a main partner of many countries that demand MAPs products for the world MAPs market. In this paper, the current situation of MAPs production in the world and Turkey are reviewed based on available data. In addition, this review touches upon Turkey's historical, cultural and economic situation as well as the subsidies for and research and development (R&D) activities focused on MAPs. Finally, the opportunities, potential, problems and outlook in this area are described in order to inform future decisions about MAPs.

Root diseases are the most difficult to tackle due to the complexity of phenotypic evaluation and the lack of resistant sources compared to other biotic stress factors. Soil-borne pathogens such as the root-lesion nematodes caused by the Pratylenchus species and crown rot caused by various Fusarium species are major wheat root diseases, causing substantial yield losses globally. A set of 189 advanced spring bread wheat lines obtained from the International Maize and Wheat Improvement Center (CIMMYT) were genotyped with 4056 single nucleotide polymorphisms (SNP) markers and screened for root-lesion nematodes and crown rot resistance. Population structure revealed that the genotypes could be divided into five subpopulations. Genome-Wide Association Studies were carried out for both resistances to Pratylenchus and Fusarium species. Based on our results, 11 different SNPs on chromosomes 1A, 1B, 2A, 3A...
