Konya İli Böğürtlen, Ahududu ve Kuşburnu Yetiştiriciliğinde Potansiyel Bir Tehdit: Ateş Yanıklığı Hastalığı

In the present study, totally 49 samples, which showed the symptoms of leaf and shoot blight and cankers with brown discoloration of necrotic tissues on mature branches, were collected from 22 districts and areas of Konya Province between 2017 and 2019. Presence rate of E. amylovora in collected samples, showing symptoms of the disease, from the province was determined to be 40% for blackberry and raspberry and 33% rosehip for rosehip in three years. Bacteria consistently isolated from the diseased tissues were identified on the basis of biochemical, physiological, and molecular tests, comparing with a reference strain of E. amylovora, isolated from blackberry (Kbb 371). Twenty seven representative bacterial strains were gram-negative, rod-shaped, mucoid, fermentative, positive for levan formation and acetoin production, no growth at 36°C, positive for gelatin hydrolysis, and negative for esculin hydrolysis, indole, urease, catalase, oxidase, arginine dehydrolase, reduction of nitrate, acid production from lactose, and inositol. All strains induced a hypersensitive response in tobacco (Nicotiana tobacum cv. White Burley) 24 h after inoculation with a 108 CFU ml-1 bacterial suspension in sterile distilled water. The strains were identified as E. amylovora using the species-specific primers set A/B (1), which amplified a 1-kb DNA fragment in PCR, and the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) method. In order to fulfill the Koch postulates, pathogenicity test was confirmed by injecting bacterial suspensions of 108 CFU ml-1 in sterile distilled water into the shoot tips of 3-year-old blackberry R. fruticosus cv. Chester, raspberry R. idaeus cv. Heritage and rosehip R. canina. All tests were repeated three times. The bacterium was re-isolated from inoculated plants and identified as E. amylovora. Phytosanitary measures are needed to prevent any further spread of the bacterium as potential inoculum sources to new blackberry, raspberry and rosehip growing areas.

Estimating the Impacts of Non-Tariff Measures in the Indian Ocean Rim Association

In recent years, the Indian Ocean Rim Association has witnessed an increasing trend in the use of non-tariff measures (NTMs). This study evaluated the impact of NTMs in the Indian Ocean Rim Association through estimations of their ad valorem equivalents at the HS chapter and country levels. A gravity model using NTM count data (intensity) was specified and estimated to derive the importer-specific ad valorem equivalents for the four (4) most used NTMs in the region. The results showed the presence of both import-impeding and import-promoting effects of NTMs; however, the import-impeding effects dominated in the region. The quantitative restriction and safeguard measures were more restrictive compared to the sanitary and phytosanitary measures and technical barriers to trade. This was expected since quantitative restrictions are trade-distorting by design. This calls for reforming trade policy in the region toward NTMs that are more transparent and trade enhancing for successful subsequent trade negotiations in the Indian Ocean Rim Association, which would support the sustainable economic development of the region.

Diversity and Pathogenicity of Diaporthe Species Revealed from a Survey of Blueberry Orchards in Portugal

Blueberries (Vaccinium corymbosum) are widely cultivated worldwide and largely consumed due to their known antioxidant and medicinal properties. Although Diaporthe species have been documented in Portugal as causal agents of blueberry twig blight and dieback, there is still scarce information on the species that cause these symptoms. Moreover, Diaporthe vaccinii, recently synonymized with D. eres, has been considered a concern to blueberry production worldwide. However, the current knowledge about its impact on blueberries remains unclear. The diversity of Diaporthe species associated with diseased blueberry plants were assessed through a national survey. A multilocus sequence analysis of the rDNA internal transcribed spacer (ITS) region, the translation elongation factor 1-alpha (tef1-α), β-tubulin (tub2), calmodulin (cal) and histone 3 (his3) genes unveiled the presence of Diaporthe ambigua, D. amygdali, D. crousii, D. foeniculina, D. hybrida, D. leucospermi, D. malorum and D. rudis. Moreover, all species were fully characterized based on a detailed morphological description. Diaporthe amygdali, D. hybrida, D. leucospermi and D. malorum are reported for the first time on diseased blueberries in Portugal. Results show that D. eres exhibited a high level of intraspecific variability within isolates, given that the strain CBS 160.32 might be a minor pathogen on blueberry plants, whereas CAA829 was revealed to be the most aggressive. Overall, this study also demonstrates that Diaporthe amygdali and D. eres may be two of the most aggressive species to blueberry plants. This study improves our understanding of the Diaporthe species and it’s causing of dieback and twig blight on Portuguese blueberry orchards. Additionally, the identification of these pathogens represents crucial information for blueberry producers to apply appropriate phytosanitary measures, as well as offering new insights into the potential pathogenicity of D. eres on this host.

The Comprehensive and Progressive Trans-Pacific Partnership

The Comprehensive and Progressive Agreement for Trans-Pacific Partnership among eleven key nations of the Pacific Rim has already expanded trade and economic cooperation among the Parties. It also serves to encourage political cooperation among them and has served as a model for future 'wide and deep' free trade agreements. The chapters of this book will provide readers with a detailed understanding of the CPTPP's coverage, including provisions relating to tariff elimination, customs rules of origin, agriculture, sanitary and phytosanitary measures, technical barriers to trade, telecommunications, intellectual property, investment and investor–state arbitration, financial and other services, government procurement, state-owned enterprises, electronic commerce and digital trade, small and medium-sized enterprises, competition law, labor and environmental protection, dispute settlement, and many others. No international lawyer, economist, trade negotiator, or enterprise can afford not to take advantage of the opportunities for business that the CPTPP offers. This book has been written by CPTPP negotiators, experts, and practitioners.

The Milk Producers’ Organization and Indian dairy sector

The needs of the Milk Producers’ Organization are achieved by strengthening the scattered and poorly organized Indian milk producers, who lack access to resources and services. In fact, the Milk Producers’ Organization has emerged as an interface between the business environment and individual milk producers through forward and backward linkages, while facilitating the strength of collective action, bargaining power and economies of scale. It has thus responded appropriately to the economic and socio-cultural needs of producer members and surrounding entities. The National Accounts Statistics (2020) of India estimates that the contribution of livestock in total agriculture and allied sectors Gross Value Added (at Constant Prices) has reached to 28.63 per cent (2018-19) which again shows the importance of the Milk Producers’ Organization in a populous country such as India. The Organization extends its assistance in the form of financial support, technical inputs, milk productivity, quality produce, managing value chains, access to market actors and handling environmental and business regulation. This review paper outlines the key viewpoints and aims to explore how the Milk Producers’ Organization has built capabilities and optimized capacities in the existing scope and challenges of the Indian dairy sector. The livestock sector supports the livelihood of approximately 20.5 million people in India. India’s milk production is at 4.8% CAGR as opposed to 1.8% CAGR of global milk production. However, the Organization faces conflicting areas of interest, such as social concern and business demands and this ambivalence necessitates enabling policy and professionalism to steer organizational growth and sustainability. In view of the globalized business environment, the Milk Producers’ Organization has taken on the responsibility to compete both on the domestic and global markets. In view of emerging international trade practices, further study is required to establish mechanisms to deal with Sanitary and Phytosanitary measures. A co-operative business model can be further explored with additional utilization of bovine manure and unproductive bovines to re-establish a more cost efficient model to deal with global price levels of milk and dairy products.

Пораженность листвы древесных насаждений города Кишинева комплексом гнилей летом 2021 года

To determine the complex of fungi that cause rot on the leaves and needles of tree species in the green spaces of Chisinau, foliage was collected in four sectors of the city. It was determined by microbio-logical methods that the complex of pathogens on the leaves differs little in different sectors. The main leaf rot fungi present on the affected leaves and needles are Alternaria sp., Aspergillus sp., Fusarium sp., Penicillium sp. For the treatment of the green spaces of Chisinau against diseases, it is advisable to carry out phytosanitary measures with biological products.
