    PRINCIPLES OF PLANT PATHOLOGY PATH 271 (1+1) Prepared By DR. P. KISHORE VARMA, ASSISTANT PROFESSOR, DEPARTMENT OF PLANT PATHOLOGY AGRICULTURAL COLLEGE, ASWARAOPET 507 301 1 LECTURE 1 INTRODUCTION TO PLANT PATHOLOGY Why Plant Pathology? Plants are essential for maintenance of life. Plants not only sustain the man and animals, they are also the source of food for multitudes of micro-organisms living in the ecosystem. Thus, while man has been able to subjugate plants and animals for his own use, the competing micro-organisms still defy his efforts and claim a major share of resources which man would like to use for himself. It is in this context that the need for fighting the competing micro-organisms and other agencies that lack loss of productivity has been felt. The attack on plants by these micro-organisms changed the appearance and productivity of the crop and this observed change was called a disease. Plant diseases have been considered as stubborn barriers to the rapid progress of food production. We call a plant healthy only so long as it continues to perform all its normal physiological activities and give the expected yield according to its genetic potentiality. Physiological activities of a healthy plant 1. Normal cell division, differentiation and development. 2. Uptake of water and nutrients from the soil. 3. Synthesis of food from sunlight by photosynthesis. 4. Translocation of water and food to the sites of necessity through xylem and phloem. 5. Metabolism of synthesized material 6. Reproduction A diseased plant fails to perform one or more of these functions.

  • Plant-Parasitic Algae (Chlorophyta: Trentepohliales) in American Samoa1
    Plant-Parasitic Algae (Chlorophyta: Trentepohliales) in American Samoa1 Fnd E. Erooks 2 Abstract: A survey conducted betweenJune 2000 and May 2002 on the island of Tutuila, American Samoa, recorded filamentous green algae of the order Tren­ tepohliales (CWorophyta) and their plant hosts. Putative pathogenicity of the parasitic genus Cephaleuros and its lichenized state, Strig;ula, was also inves­ tigated. Three genera and nine species were identified: Cephaleuros (five spp.), Phycopeltis (two spp.), and Stomatochroon (two spp.). A widely distributed species of Trentepohlia was not classified. These algae occurred on 146 plant species and cultivars in 101 genera and 48 families; 90% of the hosts were dicotyledonous plants. Cephaleuros spp. have aroused worldwide curiosity, confusion, and con­ cern for over a century. Their hyphaelike filaments, sporangiophores, and as­ sociated plant damage have led unsuspecting plant pathologists to misidentify them as fungi, and some phycologists question their parasitic ability. Of the five species of Cephaleuros identified, C. virescens was the most prevalent, followed by C. parasiticus. Leaf tissue beneath thalli of Cephaleuros spp. on 124 different hosts was dissected with a scalpel and depth of necrosis evaluated using a four­ point scale. No injury was observed beneath thalli on 6% of the hosts, but full­ thickness necrosis occurred on leaves of 43% of hosts. Tissue damage beneath nonlichenized Cephaleuros thalli was equal to or greater than damage beneath lichenized thalli (Strig;ula elegans). In spite of moderate to severe leaf necrosis caused by Cephaleuros spp., damage was usually confined to older leaves near the base of plants. Unhealthy, crowded, poorly maintained plants tended to have the highest percentage of leaf surface area affected by TrentepoWiales.

  • Etiology,Loss, Symptoms and Control of Diseases
    Phytopathology is a branch of Botany that deals with causal organism,etiology,loss, symptoms and control of diseases. ETIOLOGY:-Science of cause of disease. Pathology (Greek word‘Pathos’ and ‘Logos’.) Pathos =Suffering Logos=Study “Study of Plant Sufferings” Or “Study of Plant Diseases”. FATHER OF PLANT PATHOLOGY- ANTON de Bary. Aims of plant pathology } To make a survey of the living as well as non- living causes of the diseases. } To study the different types of mechanisms by which the diseases are developed in plants. } To elucidate the interaction mechanism among plants,pathogen and the environment. } Minimize the loss of useful plants through application of the principles of plant disease prevention. } To prevent plant disease epidemics or to delay their onset until the harvest time is over. DISEASE Disease in a plant involves a number of harmful Physiological processes which leads to a lot of irregularities in the morphology and anatomy of the host. SYMPTOMS The altered and disadvantageous differences of the host from the normal plant are referred to as Symptoms of the disease. 1. Host : An organism that harbours or supports the activities of a parasite . 2.Suscept :An organism that is susceptible or prone to disease. 3.Susceptibility :It is the inability of a plant to resist the effect of a pathogen or any other damaging factor. 4.Parasite :It is an organism or virus existing in an intimate association with another living organism from which it derives an essential part of the materials for its existance. 5.Pathogen :A pathogen is an organism or virus capable of causing disease in a particular host.

    Major Diseases of Horticultural Crops and this Management Dr.G. Thiribhuvanamala, Dr.S.Nakkeeran and Dr. K.Eraivan Arutkani Aiyanathan Department of Plant Pathology Centre for Plant Protection Studies Tamil Nadu Agricultural University Coimbatore – 641 003 Introduction: The Horticulture (fruits including nuts, vegetables including potato, tuber crops, mushroom, ornamental plants including cut flowers, spices, plantation crops and medicinal and aromatic plants) has become a key drivers for economic development in many of the states in the country and it contributes 30.4 per cent to GDP of agriculture, which calls for knowledge and technical backstopping. Intensive cultivation of the high valued horticultural crops, resulted in the outbreak of several diseases of National importance. In recent days, stakeholders import planting materials from North American Countries. Introduction of planting materials also impose threat in the introduction of new diseases not known to be present earlier. However, the diseases, if not managed on a war foot, it will result in drrastic yield reduction and quality of the produces. Hence adoption of suitable management measures with low residue levels in the final produces becomes as a need of the hour. In this regard, this paper gives emphasis on the diagnosis of plant diseases and their management. 293 Diseases of Mango and their management 1. Anthracnose :Colletotrichum gloeosporioides Anthracnose symptoms occur on leaves, twigs, petioles, flower clusters (panicles), and fruits. The incidence of this disease can reach almost 100% in fruit produced under wet or very humid conditions. On leaves, lesions start as small, angular, brown to black spots and later enlarge to form extensive dead areas.

Palatine Hill Road MSC 53, Portland, OR 97219, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-530-754-9894 Academic Editors: Matteo Garbelotto and Paolo Gonthier Received: 15 March 2017; Accepted: 27 April 2017; Published: 28 April 2017 Abstract: The disease triangle is a basic and highly flexible tool used extensively in forest pathology. By linking host, pathogen, and environmental factors, the model provides etiological insights into disease emergence. Landscape ecology, as a field, focuses on spatially heterogeneous environments and is most often employed to understand the dynamics of relatively large areas such as those including multiple ecosystems (a landscape) or regions (multiple landscapes). Landscape ecology is increasingly focused on the role of co-occurring, overlapping, or interacting disturbances in shaping spatial heterogeneity as well as understanding how disturbance interactions mediate ecological impacts. Forest diseases can result in severe landscape-level mortality which could influence a range of other landscape-level disturbances including fire, wind impacts, and land use among others. However, apart from a few important exceptions, these disturbance-disease interactions are not well studied. We unite aspects of forest pathology with landscape ecology by applying the disease-triangle approach from the perspective of a spatially heterogeneous environment. At the landscape-scale, disturbances such as fire, insect outbreak, wind, and other events can be components of the environmental ‘arm’ of the disease triangle, meaning that a rich base of forest pathology can be leveraged to understand how disturbances are likely to impact diseases.

  • Roles of the Plant Cell Wall in Powdery Mildew Disease
    Roles of the plant cell wall in powdery mildew disease resistance in Arabidopsis thaliana: PMR5 (POWDERY MILDEW RESISTANT 5) affects the acetylation of cell wall pectin By Candice Cherk Lim A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Plant Biology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Shauna Somerville, Chair Professor Patricia Zambryski Associate Professor Mary Wildermuth Professor James Berger Spring 2013 Abstract Roles of the plant cell wall in powdery mildew disease resistance in Arabidopsis thaliana: PMR5 (POWDERY MILDEW RESISTANT 5) affects the acetylation of cell wall pectin by Candice Cherk Lim Doctor of Philosophy in Plant Biology University of California, Berkeley Professor Shauna Somerville, Chair The pmr5 (powdery mildew resistant 5) mutant was found in a screen for genes involved in susceptibility to Golovinomyces cichoracearum, a biotrophic pathogen that infects Arabidopsis. PMR5 is a member of the TBL (TRICHOME BIREFRINGENCE LIKE) family, which is composed of 46 functionally uncharacterized plant-specific proteins. Initial characterization of this mutant showed that pmr5-mediated disease resistance acts independently of the salicylic acid, jasmonic acid, and ethylene signal transduction pathways, and that there are changes in the pmr5 cell wall that may be linked to the gain of resistance in the mutant. Specifically, PMR5 may be affecting cell wall pectin by acetylation. Characterization of the pmr5 cell wall has revealed changes in pectin composition and a decrease in acetylation. This is corroborated by the ability of heterologously expressed PMR5 protein to bind to pectin, with decreased binding affinity to acetylated pectin.

The interrelationships between host and parasite have a dynamic character, that is, they change with time, which has to be recognized in a proper description of the substrate and the environment of a parasitic organism. In the past, most studies of disease and pest management have emphasized the population dynamics of the disease and pest organisms, but their association with the growing crop has been virtually neglected. Elaborate studies on the popula­ tion dynamics of pests or disease-causing organisms may be used in predicting future pest and disease intensity, but the value of these studies is limited when a reliable assessment of damage is not available. Models may help to develop management strategies. Among dynamic models, various types can be distinguished according to the objectives of the study. When explanation is the aim, the corresponding explan­ atory models based on a systems hierarchy try to predict and explain integrated behaviour from a more detailed knowledge of the underlying physiological and morphological processes (De Wit & Goudriaan, 1978; De Wit et al., 1978). Much of the information presented in other chapters of this book illustrates stud­ ies of detailed plant physiological processes involved in crop-pathogen interre­ lations.
