Our motherland is no exception to this! Food security continues to be high on the list of development priorities of India because the country’s relatively high rates of economic growth have not led to a reduction in hunger and under nutrition whereas overwhelming majority of the Indian population depend upon agriculture as their primary source of income. Growing global population in present backdrop of climate change has put tremendous challenges before the agricultural scientists to meet the ever-growing demands of food and nutritional security. Injudicious use of natural resources, lack of well-formulated crop production and protection technologies for raising agricultural and horticultural crops and the ill-effects of climate change are imposing onerously challenging dimensions particularly in relation to the crop productivity, sustainable food and livelihood security of farmers and increasing vulnerability to natural calamities. Plant pests and diseases could potentially deprive humanity of over 50% of crop production and combined with postharvest spoilage and deterioration in quality, these losses become critical, especially for resource-poor regions. However, the components of climate change, such as global warming, ground water depletion, shifting rainfall pattern, changing dimensions of natural calamities, depletion of cryosphere etc. has manifold influence on agriculture and efficiency of crop protection practices. Varietal uniformity of crops coupled with increasing genetic variability of pest and pathogens, excessive use of pesticides and changing climatic scenario has led to the outbreak of many pest and pathogens considered to be less important earlier. However, biological interactions laid behind are rather complex and integrated solutions and international co-ordination in their implementation is considered essential. The Indian Phytopathological Society (IPS) has been constantly trying to address some of these vexed issues and focussing on the problem related to food security vis-a-vis sustainable agriculture in existing backdrop since its birth. Department of Plant Pathology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal in collaboration with IPS(East Zone) are now organising East Zone meet cum National Symposium on “Challenges and Prospective in Plant Health Management under Climate Change Scenario with two major objectives: (a) understanding the present scenario in plant protection and (b) to invite the researchers on a common platform for exchanging their experiences, knowledge, views, innovative ideas and latest developments on this aspect for preparing a road map to handle the issues of plant health management for food security under climate change scenario. It is proposed and hoped that with adequate domestic participation of researchers across the country in a common interactive platform in the Symposium, it would be possible to formulate relevant strategies for conservation of biodiversity, improving crop productivity with resilience to the plant health and mitigating traumas of climate change.

In this paper, generic names in Pucciniomycotina and Ustilaginomycotina are evaluated pleomorphic fungi based on their type species to determine which names are synonyms. Twenty-one sets of sexually and asexually taxonomy typified names in Pucciniomycotina and eight sets in Ustilaginomycotina were determined to be congeneric and protected names compete for use.

Four data sets were analysed: a) the internal transcribed spacer region including ITS1, 5.8S rDNA and ITS2 (ITS), b) nc28S (ncLSU) rDNA, c) nc18S (ncSSU) rDNA, and d) a combined data set of ncLSU-ncSSU-RPB2 (ribosomal polymerase B2). The traditional placement of Ch. tulasneorum in the Microascales based on ncLSU sequences is unsupported and Australiasca does not belong to the Chaetosphaeriaceae. Both holomorph species are nested within the Glomerellales. A new genus, Reticulascus, is introduced for Ch. tulasneorum with associated Cylindrotrichum anamorph; another species of Reticulascus and its anamorph in Cylindrotrichum are described as new. The taxonomic structure of the Glomerellales is clarified and the name is validly published. As delimited here, it includes three families, the Glomerellaceae and the newly described Australiascaceae and Reticulascaceae. Based on ITS and ncLSU rDNA sequence analyses, we confirm the synonymy of the anamorph generaDischloridium with Monilochaetes.

    RESEARCH ARTICLE SCIENCE INTERNATIONAL DOI: 10.17311/sciintl.2015.82.84 In vitro Efficacy of Fungicides and Bioagents Against Wilt of Pigeonpea Caused by Neocosmospora vasinfecta 1R.R. Khadse, 1G.K. Giri, 2S.A. Raut and 1B.B. Bhoye 1Department of Plant Pathology, Dr. Panjabrao Deashmukh Krishi Vidyapeeth, Akola, India 2Mahatma Phule Agricultural University, Rahuri, Dist Ahmednagar, India ABSTRACT Background: Pigeon pea (Cajanus cajan) is one of the important leguminous crop of the tropics and subtropics and is infected by the wilt pathogen Neocosmospora vasinfecta in addition to Fusarium udum. Objective: Hence, the study was undertaken to see the in vitro effect of different fungicides (Thiram 75 WP, Carbendazim 50 WP, Chlorothalonil 75 WP, Metalaxyl MZ 72 WP, Thiram+Cabendazim (2:1), Carbendazim+mancozeb 75 WP, Tricyclazole+Mancozeb 80 WP, Zineb+Hexaconazole 72 WP) and bioagents (Trichoderma harzianum, Pseudomonas fluorescens, Bacillus subtilis) against the pathogen. Methodology: The efficacy of fungicides was assayed by poisoned food technique and of bioagents was assayed by dual culture technique. Results: It was found that among eight fungicides tested carbendazim (0.1%), combination of carbendazim+mancozeb (0.2 %) and thiram+carbendazim 2:1 (0.3%) exhibited cent per cent inhibition of N. vasinfecta, other fungicides were also significant over control. Whereas among bioagents tested, Trichoderma herzianum (50.30%) showed maximum per cent growth inhibition of the pathogen followed by Bacillus subtilis (41.47%). Conclusion: Thus it was proved that the fungicides viz. carbendazim, combinations of carbendazim+mancozeb and thiram+carbendazim as well as bioagent, T. herzianum were effective against Neocosmospora wilt of pigeon pea under in vitro condition.

    BOOK OF ABSTRACTS OPENING SESSION Opening lecture 1 Global change is a challenging parameter for plant pest risk assessment. Charles Manceau1 1Anses – French agency for food, environmental and occupational health & safety, 7 rue Jean Dixméras, F- 49044 Angers Cedex 01, France Global change refers to planetary-scale changes in the Earth system which includes human society. Global change encompasses climate, land use, biodiversity, trade of plant and plant parts and has a strong and well defined impact on plant health despite the short time frame under consideration. Emerging plant diseases present many serious issues for human well-being, whether in agricultural, forestry, environmental or regulatory arenas. The temporal and spatial scales of plant disease emergence are defining features related to local, national and global drivers. These include the increases in global trade, of course, but also the introduction of novel crop, changes in production systems, interactions occurring at the landscape level and the impact of climate change. Agroecology is a one of the drivers that raise questions about the predictability of emerging plant diseases Pest risk analysis (PRA) is the process used by National Plant Protection Organizations (NPPOs) as the technical justification for phytosanitary measures. PRA is defined by the International Plant Protection Convention (IPPC) as “the process of evaluating biological or other scientific and economic evidence to determine whether a pest should be regulated and the strength of any phytosanitary measures to be taken against it.” The process requires a risk assessment to characterize the risk and risk management to determine appropriate measures. PRAs are mainly performed in the context of the international trade.

Damm, [email protected], Present address: Senckenberg Museum of Natural History Görlitz, PF 300 154, 02806 Görlitz, Germany. Abstract: Colletotrichum destructivum is an important plant pathogen, mainly of forage and grain legumes including clover, alfalfa, cowpea and lentil, but has also been reported as an anthracnose pathogen of many other plants worldwide. Several Colletotrichum isolates, previously reported as closely related to C. destructivum, are known to establish hemibiotrophic infections in different hosts. The inconsistent application of names to those isolates based on outdated species concepts has caused much taxonomic confusion, particularly in the plant pathology literature. A multilocus DNA sequence analysis (ITS, GAPDH, CHS-1, HIS3, ACT, TUB2) of 83 isolates of C. destructivum and related species revealed 16 clades that are recognised as separate species in the C. destructivum complex, which includes C. destructivum, C. fuscum, C. higginsianum, C. lini and C. tabacum. Each of these species is lecto-, epi- or neotypified in this study. Additionally, eight species, namely C. americae- borealis, C. antirrhinicola, C. bryoniicola, C.

Pages 2 – 4: Tomato crown rot disease spreading to new This edition discusses two tomato diseases, one fungal areas (tomato crown rot) and the other caused by a viroid (tomato chlorotic dwarf). Both are dangerous diseases for the Pages 5 - 6: Tomato chlorotic tomato industry. Medflies have invaded California once dwarf viroid in Hawai’i again, with outbreaks in Solano, Los Angeles, and San Mateo counties. They just keep coming!

Mycosphere 7(8) 1164–1176, Doi 10.5943/mycosphere/si/2c/7 Abstract The genus Colletotrichum has received considerable attention in the past decade because of its role as an important plant pathogen. The importance of Colletotrichum with regard to industrial application has however, received little attention from scientists over many years. The aim of the present paper is to explore the importance of Colletotrichum species as bio-control agents and as a bio-catalyst as well as secondary metabolites and toxin producers. Often the names assigned to the above four industrial applications have lacked an accurate taxonomic basis and this needs consideration. The current paper provides detailed background of the above topics. Key words – biotransformation – colletotrichin – mycoherbicide – mycoparasites – pathogenisis – phytopathogen Introduction Colletotrichum was introduced by Corda (1831), and is a coelomycete belonging to the family Glomerellaceae (Maharachchikumbura et al. 2015, 2016). Species of this genus are widely known as pathogens of economical crops worldwide (Cannon et al.

It primarily attacks host stems including roots, fruits, petioles and leaves under favourable conditions. It commonly occurs in the tropics, subtropics and other warm temperate regions of the world. Common hosts are legumes, crucifers and cucurbits. On a global perspective, estimated losses of 10 – 20 million dollars associated with S. rolfsii have been recorded with yield depletion ranging from 1 – 60% in fields. Sclerotia serve as primary inoculum for the pathogen and are spread to uninfected areas by wind, water, animals and soil. Control measures include excluding the pathogen from the area, plant removal, soil removal, soil treatment, heat, solarization, chemical soil treatment, cultural practices, resistance and transgenic plant resistance, plant treatment, crop rotation, amongst others. Despite considerable research on this pathogen, its control continues to be a problem. Keywords: Sclerotium rolfsii, stem rot, white mold, stem blight. _____________________________________________________________________________________________ INTRODUCTION Sclerotium rolfsii is a destructive soil borne plant pathogen which causes Southern blight disease on a wide variety of plants. In 1928, the United States Department of Agriculture reported that S.
