A Handbook Of Rice Seedborne Fungi

Seed health testing assures the safe movement of seed of different crops, for research or trade. It is premised on the hypothesis that many harmful organisms are carried by and moved with the seed which have the potential to harm crops. This text provides details of rice seed-borne fungi.

Rice seed health and quarantine; The rice plant and its environment; Equipment; Samples and sampling; dry seed inspection; Fungi; Bacteria; Nematodes; Viruses and mycoplasmalike organisms; Field inspection; Seed treatment; Weed seed; Insect pests; Fungal pathogens; Bacterial pathogens; Nematode pest; Organisms causing grain discoloration and damage.

This book is the result of finding of a research conducted on rice seeds collected from Syangja district of Nepal. There were forty-five different varieties of rice seed including improved, hybrid and local; collected from farmers and tested in laboratory to find different fungal pathogens. Seven different species of fungal pathogens were detected with various level of seed infection. Improved and hybrid varieties were found to be infected higher than that of local varieties. Nine different treatments including chemicals and different local botanicals were tested for their efficacy to control those pathogens also.

Major Fungal Diseases of Rice: Recent Advances provides a comprehensive overview of latest research in rice fungal pathology. There are 25 chapters dealing with the blast, sheath blight, sheath rot, brown spot and scald diseases of rice as well as some broader topics. The book covers recent progress in a number of key fundamental aspects such as pathogenicity, pathogen diversity, molecular characterisation, gene cloning, genetics of host resistance and host-pathogen interactions. It also presents the current status and perspectives in strategic and applied areas such as epidemiology, resistance breeding, biological control, induced resistance, seed-borne diseases and quarantine issues and disease management strategies. This book is essential for rice researchers, pathologists and breeders and will also be suitable for cereal and plant pathologists in general, as there is an extensive coverage of recent research advances in rice blast, a model system in plant pathology.

Seed borne disease is a serious problem for successful crop production in Bangladesh. Among all the groups of seed borne pathogens, fungi play significant role in causing seed borne diseases. Considerable amount of research works have been conducted on the association of seed borne fungal pathogens with rice and on the control of seed borne infection of the crop with chemicals but little work has been carried out on the control of seed-borne fungal pathogens with plant extract in Bangladesh.

"Rice is a widely consumed crop around the world that has tremendous importance and is cultivated almost everywhere except Antarctica. However, various biotic and abiotic stresses have a negative effect on rice cultivation, seriously reducing its yield. This volume examines the bacterial and fungal pathogens that can cause rice diseases and explores how to manage these diseases. The volume covers the economic and environmental impact of rice fungal diseases on global food security and proceeds to delve into diagnostic methods for rice fungal pathogens, discussing both traditional and molecular techniques for detection. The volume discusses the potential of biocontrol agents for the sustainable management of rice fungal diseases and also provides new insights from the bioinformatic tools for rice fungal disease resistance. This book presents a number of key fundamental aspects such as pathogen ecology, epidemiology, and host-pathogen interactions of rice and offers a plethora of control measures to mitigate harm from fungal diseases. It presents an analysis of the current status of resistance genes as well as current strategic and applied methods, such as biotechnology, bioinformatics tools, and biological methods for the effective management of rice fungal diseases. Computational deciphering of blast resistant genes is also discussed. It elaborates on the ecology and research status of diseases and pathogens of rice, including rice sheath blight pathogen, sheath rot disease, rice blast pathogens, rice brown spot disease, rice kernel smut pathogen, rice bakanae/foot rot disease, and others. Fungal Diseases of Rice and Their Management is a valuable resource and guide for research students, rice breeders, rice biotechnologists, and others involved in rice research, production, and cultivation"--
