This Serves as an exclusive source of information BSR caused by G. boninense. It is a valuable and a must reference and guide for planters, agricultural students, agronomists and all those working in the oil palm industry. The authors believe this book will complementing the existing books on different approaches in the similar field as this book will discuss in-depth details and guidance on controlling the BSR disease using biological means, which is the unique features of the book itself. This book compiles precise and detail information on current detection methods. Infection of Ganoderma only appear at the very late stage of infection where more than 70% of the internal tissues have decayed, leaving no chance to cure the infected palms. Therefore, early detection of infected palms in advance of terminal symptoms is crucial. New approaches which has been proven possible to be conducted in field will be also provided. The key advantages of the reviewed detection methods are to help the readers to determine the best measure they could apply that suit their availability and accessibility. Oil palm is an international commodity used for food, household and industrial purposes. It is the world highest oil producer crop with potential yield capacity of 10 to 15 times higher compares to other oil crops planted on the same size of land. Increases in global demand for edible oil and biofuel, driven by the increasing population remains the main factor driving up the expansion of oil palm cultivation in South East Asia (SEA) countries and other region of the world. Currently, Malaysia and Indonesia are the two countries which contributed to 90% of the world’s palm oil export. Unfortunately, the oil palm industry in SEA is under threat of a devastating disease. This disease is known as Basal Stem Rot (BSR) which caused by a fungus, Ganoderma boninense. In Malaysia alone, the economic loss caused by this disease was estimated between RM 225 million to RM 1.5 billion (up to 500 million USD) a year. With no known remedy at present, BSR disease continues to erode the profitability of the oil palm industry, and created a significant concern globally. This book is a joint effort by the authors whom are currently working actively on finding control methods of BSR disease in oil palm. With immense experience in the field, this book provides information with data backup covering both detection and control strategies of Ganoderma. Many researchers have agreed that most of the failures to control this pathogen are due to the lack of knowledge about this pathogen. Hence, this book provides information on the pathogenic nature of G. boninense. Prior understanding of the pathogen biology and their mode of infection provides the audience a new insight into BSR epidemiology that enables the implementation of appropriate management strategies. This book presents a detailed review on the control measures on BSR disease that is currently taken. These include cultural control that is practised most of the time, chemical control using formulated fungicidal and development of disease resistance variety. Focusing on a specific issue which need urgent attention with good supporting data, this book gives a more in depth information on the use of biological approaches in controlling G. boninense to meet the current oil palm-environmental dilemmas and demand of more eco-friendly practices in the field. Biological agents have been proven to be successful in many different models. In this book, the proposed methods address combinations of biological control agents (BCA) to improve the limitations of single BCA application. The results presented are based on trials conducted all the ways from in vitro to nursery and finally in the field (under the most commonly practiced agronomic practices). The 6 chapters in this book address many current issues in tackling the pathogen and development of sustainable disease managment programmes. There are, an introduction to the oil palm industry in global prespective and its future potential (Chapter 1), The pathogenic nature of Ganoderma (Chapter 2), Current detection methods of G. boninense which are sub-divided into Lab-based and Field detection methods (Chapter 3), Control methods of the pathogen, which covers cultural practices, chemical control, development of disease resistance and biological control (Chapter 4), Integrated control of G. boninense using combination of biocontrol agents (Chapter 5) and finally an overview of the book content which summarize the discussed matters as well as suggest several recommendations for future research or improvement attempts (Chapter 6).

Annotation. Diseases caused by Ganoderma species cause major losses of palms and other perennial crops throughout the world, and these are particularly significant in Asia. Successive replanting of crop monocultures can be rapidly exploited by soil borne fungi such as Ganoderma, and the problem will become more serious in the 21st century, as more areas become due for second or even third replanting. Environmental considerations will reduce exploitation of new forest areas, making further replanting of these crops inevitable. Thus, appropriate, integrated management systems for these diseases are vital. However, the development of such control measures has been hampered in the past by a limited knowledge of the nature and inter-relationships of populations of different hosts and the mechanisms of disease establishment and spread.This book aims to address these limitations through enhanced knowledge of the biology and taxonomy of Ganoderma species. The use of molecular and biochemical methods can be used to provide a greater understanding of the spread of the pathogen, and consequently, the improved management of disease.

The fungal genus Ganoderma includes around 80 currently recognized species that are widely distributed in temperate, subtropical and tropical regions, and cause disease in a range of economically important perennial crops and tree-like plants. Ganoderma root and lower stem rots have a significant impact on yields from crops including oil palm, coconut, beverage crops, Acacia and rubber. The identification of species responsible for stem and butt rots is often ambiguous as closely related species may only be distinguished by subtle morphological differences. Within species there can be considerable morphological plasticity and this can make morphology-based identification difficult, particularly for species described from a single specimen. Molecular techniques are helping to slowly resolve Ganoderma taxonomy but it will be some time (if ever) before the taxonomy is fully resolved. This book brings together information on Ganoderma species that are reported to be responsible for crop diseases in tropical and sub-tropical agriculture and covers taxonomy, biology, genetics, aetiology, epidemiology and control. This book is an essential resource for researchers in Ganoderma in crop science and tropical agriculture, as well as practitioners and industry.

The oil palm is a remarkable crop, producing around 40% of the world’s vegetable oil from around 6% of the land devoted to oil crops. Conventional breeding has clearly been the major focus of genetic improvement in this crop. A mix of improved agronomy and management, coupled with breeding selection have quadrupled the oil yield of the crop since breeding began in earnest in the 1920s. However, as for all perennial crops with long breeding cycles, oil palm faces immense challenges in the coming years with increased pressure from population growth, climate change and the need to develop environmentally sustainable oil palm plantations. In Oil Palm: Breeding, Genetics and Genomics, world leading organizations and individuals who have been at the forefront of developments in this crop, provide their insights and experiences of oil palm research, while examining the different challenges that face the future of the oil palm. The editors have all been involved in research and breeding of oil palm for many years and use their knowledge of the crop and their disciplinary expertise to provide context and to introduce the different research topics covered.

Single application of biological control agent may prove to be an effective agent for suppressing basal stem rot (BSR) disease in oil palm. However, in nature, there are numerous organisms that may have antagonistic behavior to a particular pathogen existing in the same space and interacting to each other. The main objective of this study was to investigate the effectiveness of mixed antagonists inocula against the palm fungal pathogen, Ganoderma boninense. A total of 803 microbes were obtained from freshly isolated of various substrates and 197 isolates from UNIMAS culture collection. They were screened for their antagonistic activities against G. boninense. Results from the screening tests showed that 233 of the isolates were able to inhibit the growth of the pathogen in four different interactions; formation of inhibition zone, partial mutual intermingling, mutual intermingling and inhibition at contact point. Some changes in characteristics of mycelia and hyphae of pathogen were seen depending on the type of interaction with the antagonist for instance changes in mycelial color from white to dark brown and the hyphae became shrunken, distorted, reduction of cytoplasm content and the tips were blunted, swollen and some were curly. Fifteen selected isolates forming zone of inhibition were formulated into five mixed antagonists inocula against the G. boninense. The mixture that resulted highest percentage of reduction of the colony radial growth of the pathogen was selected for further study on their compatibility and for in situ. The mixed antagonists inocula comprised of Penicillium citrinum, Penicillium pinophilum and Burkholderia gladioli produced the highest zone of inhibition up to 61.89%. These three isolates showed compatibility since they were able to grow together. Oil palm seedlings were treated with two different concentrations of v the mixed antagonists inoculums, 2.7 x 107 spores/ml (T2) and 2.7 x 1014 spores/ml (T3). Seedlings without infected, (T0) or infected with the pathogen but not treated with the antagonists, (T1) were used as the control experiment. In in situ tests, T2 and T3 seedlings were successfully inhibiting the growth of the G. boninense when observed after 5 months of application. Based on disease severity index (DSI), root dry weight and chlorophyll content, there was no significant different (p=0.05) between T2 and T3 seedlings. However, there was significant different, (p

Crops experience an assortment of environmental stresses which include abiotic viz., drought, water logging, salinity, extremes of temperature, high variability in radiation, subtle but perceptible changes in atmospheric gases and biotic viz., insects, birds, other pests, weeds, pathogens (viruses and other microbes). The ability to tolerate or adapt and overwinter by effectively countering these stresses is a very multifaceted phenomenon. In addition, the inability to do so which renders the crops susceptible is again the result of various exogenous and endogenous interactions in the ecosystem. Both biotic and abiotic stresses occur at various stages of plant development and frequently more than one stress concurrently affects the crop. Stresses result in both universal and definite effects on plant growth and development. One of the imposing tasks for the crop researchers globally is to distinguish and to diminish effects of these stress factors on the performance of crop plants, especially with respect to yield and quality of harvested products. This is of special significance in view of the impending climate change, with complex consequences for economically profitable and ecologically and environmentally sound global agriculture. The challenge at the hands of the crop scientist in such a scenario is to promote a competitive and multifunctional agriculture, leading to the production of highly nourishing, healthy and secure food and animal feed as well as raw materials for a wide variety of industrial applications. In order to successfully meet this challenge researchers have to understand the various aspects of these stresses in view of the current development from molecules to ecosystems. The book will focus on broad research areas in relation to these stresses which are in the forefront in contemporary crop stress research.

The book covers the latest development in the biosciences field covering key topics in crop improvement including ‘omic approaches to improving sustainable crop production, advancement in marker technology, strategies in genetic manipulation, crop quality and sustainability and plant microbe interaction detailing on proven technologies to address critical issue for agricultural sustainability which are beneficial for researchers and students. The book also includes aspects of preserving crops after harvest as this is a key factor in promoting sustainable crop quality in terms of addressing waste, choosing the appropriate packaging and moving crops through the food and industrial supply chain. An important strategy to overcome the challenges in providing food for the world population in a sustainable manner is through concerted efforts by crop scientists to embrace new technologies in increasing yield, quality and improving food safety while minimizing adverse environmental impact of the agricultural activities. Most of the proven molecular and genetic technologies in crop science have been tested and verified in model plants such as Arabidopsis and tomato. The technologies, when deployed on various plant species of importance for human nutrition and industrial applications, including cereals, vegetables, fruits, herbs, fibre and oil crops, face many challenges, not only due to their longer life cycle but many other physiological and environmental factors affecting yield and quality of plant products. Furthermore, major impacts on crop production due to catastrophic diseases and global climate change needs urgent and innovative solutions. Therefore a systematic approach, employing various leading-edge technologies that enable the functional elucidation of key pathway genes via ‘omics tools, genome wide association with desired phenotypes and development of cost effective and practicable molecular tools for selection, is vital. The International Conference on Crop Improvement was held to address these and other pressing issues. This volume summarizes the keynote presentations from the meeting and highlights addition discussions that are critical to crop improvement in a challenging time.
