Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens.Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.

Saroja and Kumaresan are young and in love. After meeting in a small southern Indian town, where Kumaresan works at a soda bottling shop, they quickly marry before returning to Kumaresan's family village to build a new life together. But they are harbouring a dangerous secret: Saroja is from a different caste than Kumaresan, and if the villagers find out, they will both be in grave peril. Faced with venom from her mother-in-law, and questions from her new neighbours, Saroja tries to adjust to a lonely and uncomfortable life, while Kumaresan struggles to scrape together enough money for them to start over somewhere new. Will their love keep them safe in a hostile world?

A vibrant fable of marriage, caste and social convention from one of the most exciting voices in contemporary Indian fiction 'Unexpected and moving' Amitava Kumar, author of Immigrant, Montana 'A major Indian writer' New York Times 'A captivating story of love and desire' Vivek Shanbhag, author of Ghachar, Ghochar Kali and Ponna are perfectly content in their marriage, apart from one thing. They are unable to conceive. With local gossip and family disapproval mounting, the increasingly desperate couple consider a more drastic plan. They will attend the annual chariot festival, a celebration of the half-male, half-female god Maadhorubaagan. For one night, the rules of marriage are relaxed, and consensual sex between unmarried men and women is overlooked, for all men are considered gods.Could this be the opportunity that they've been searching for?

'Pyre glows with as much power as [One Part Woman] did, and adds immeasurable value to contemporary Indian literature'-The HinduSaroja and Kumaresan are in love. After a hasty wedding, they arrive in Kumaresan's village, harboring a dangerous secret: their marriage is an inter-caste one, likely to upset the village elders should they get to know of it. Kumaresan is naively confident that all will be well. But nothing is further from the truth. Despite the strident denials of the young couple, the villagers strongly suspect that Saroja must belong to a different caste. It is only a matter of time before their suspicions harden into certainty and, outraged, they set about exacting their revenge.A devastating tale of innocent young love pitted against chilling savagery, Pyre conjures a terrifying vision of intolerance.

The vision he saw in his dream, a world in ruins and bereft of women-was that going to come true soon? If he could get married, he would live the way people lived in the old days. He wanted to have at least ten children, and he wanted them all to be girls. The world should never again witness the sorrow of a man like him. It might be a truth universally acknowledged that a single man in possession of a good fortune, or at least a piece of land, must be in want of a wife, but Marimuthu's path to marriage is strewn with obstacles big and small. Inward-looking, painfully awkward, desperately lonely and deeply earnest, Marimuthu is fuelled by constant rejection into an unforgettable and transformative matrimonial quest. Enter a series of marriage brokers, horoscopes, infatuations, refusals and 'bride-seeing' expeditions gone awry, which lead Marimuthu to a constant re-evaluation of his marital prospects. But this is no comedy of manners, and before long we find ourselves reckoning with questions of agricultural change, hierarchies of caste, the values of older generations and the grim antecedents of Marimuthu's poor prospects, as decades of sex-selective abortion have destroyed the fabric of his community and its demographics. Perumal Murugan's Resolve is both a cultural critique and a personal journey: in his hands, the question of marriage turns into a social contract, deeply impacted by the ripple effects of patriarchy, inequality and changing relationships to land and community. In this deceptively comic tale that savagely pierces the very heart of the matter, translated with deft moments of lightness and pathos by Aniruddhan Vasudevan, Perumal Murugan has given us a novel for the ages.

A farmer in India is watching the sun set over his village one quiet evening when a mysterious stranger, a giant man who seems more than human, appears on the horizon. He offers the farmer a black goat kid who is the runt of the litter, surely too frail to survive. The farmer and his wife take care of the young she-goat, whom they name Poonachi, and soon the little goat is bounding with joy and growing at a rate they think miraculous. But Poonachi's life is not destined to be a rural idyll: dangers lurk around every corner, and may sometimes come from surprising places, including a government that is supposed to protect the weak and needy. Is this little goat too humble a creature to survive such a hostile world? With allegorical resonance for contemporary society and examining hierarchies of caste and colour, The Story of a Goat is a provocative but heartwarming fable from a world-class storyteller who is finally achieving recognition outside his home country.
