Klein, Jeffrey A. Golus and Greg R. Kruger Preface Fungicides are a class of pesticides used for killing or inhibiting the growth of fungus. They are extensively used in pharmaceutical industry, agriculture, in protection of seed during storage and in preventing the growth of fungi that produce toxins. Hence, fungicides production is constantly increasing as a result of their great importance to agriculture. Some fungicides affect humans and beneficial microorganisms including insects, birds and fish thus public concern about their effects is increasing day by day. In order to enrich the knowledge on beneficial and adverse effects of fungicides this book encompasses various aspects of the fungicides including fungicide resistance, mode of action, management fungal pathogens and defense mechanisms, ill effects of fungicides interfering the endocrine system, combined application of various fungicides and the need of GRAS (generally recognized as safe) fungicides. This volume will be useful source of information on fungicides for post graduate students, researchers, agriculturists, environmentalists and decision makers. This volume includes 13 chapters. The first chapter elaborates the problems associated with fungicide application, disease epidemiology, decision-making process, fungicide’s physical mode of action, resistance and its management with two case studies on strawberry and grape. The second chapter describes the problem of Botrytis resistance, monitoring methods, anti-resistant strategies, Botrytis cinerea MDR types, their mechanisms of resistance etc. in detail. The third chapter presents overall information on the multiple fungicide resistant Botrytis affecting German soft fruits such as raspberry and strawberry fruits. This article gave sufficient background information on fungicide resistance in Botrytis cinerea, resistance assay developed, reproducibility of the assay, temporal and special distribution of fungicide resistance, the major issues of multiple fungicide resistance, factors conducive for the spread of B. cinerea, fungicide application, etc. It will be useful not only to the researchers but also to the regional soft fruit growers. Fourth chapter is a comprehensive account of reviewing the Fenhexamid resistance in the Botrytis species responsible for grey mould disease. The authors have included their research outputs and incorporated recent publications in this chapter which helps to understand basic and applied aspects of this research field. X Preface The effects of fungicide application on the FHB disease complex with a combined approach of in vitro and in vivo field trials are discussed in the chapter 5. Sixth chapter explaining the utilization of beneficial bacteria such as Pseudomonas fluorescens, Bacillus subtilis and Bacillus megaterium against pathogenic fungi Rhizoctonia solani and Pythium debarianum. Seventh chapter presents sufficient background information on origin, distribution, fungal pathogens and diseases of apple, fungal toxins, defence mechanisms, alternative measures to control post harvest blue mould of apple etc. and it will be useful to the researchers as well as people involved in cultivation of apple. The author of the eighth chapter has sufficiently discussed the effect of old and new fungicides on various fruits, combined application of various fungicides and thermotherapy on various horticultural commodities, and the need of GRAS (generally recognized as safe) fungicides as an alternative to traditional fungicides which are ineffective against resistant strains. Ninth chapter describes the role of Mitogen Activated Protein Kinase (MAPK) signaling in secondary metabolism and adaptation to abiotic/fungicide stress in Fusarium using ∆Fvhog1 and ∆Fvmk2 CWI MAPK mutants of F. verticillioides by comparing their sensitivity to different oxidative stressors. The authors of this chapter elaborate the role of HOG1 MAPK signaling in stress and fungicide tolerance, the role of MAPK pathways in secondary metabolism of Fusarium species, complexity of oxidative stress signaling in fungi and sensitivity of different Fusarium species to hydrogen peroxide. Tenth chapter presents the Endocrine Disruptor Compounds (EDCs) such as tributyltin (androgen) and vinclozolin (anti-androgen) and their effects on vertebrate and invertebrate taxa including non target organisms. The ill effects of these fungicides interfering the endocrine system in the synthesis, secretion, transport, action or elimination of natural hormones, including in the induction of cell tumors, reduction of ejaculated sperm numbers and prostate weight and delayed puberty are clearly described in this article. As many pathogens develop resistance under field conditions due to frequent application of various fungicides, the eleventh chapter paper presents detailed information on the laboratory mutant of Bipolarize oryzae resistant to Carbendazim and follows intensive studies on molecular mechanisms of the fungicide resistance to benzimidazole compound. Twelfth chapter describes the epidemiological context of Mycosphaerella graminicola, the effect of other factors such as external contamination by ascospores, cultivars resistance, leaf colonization stages, fungicide efficiency using qPCR and correlation between qPCR analysis and visual symptoms. Thirteenth chapter explains the efficacy of fungicide applications, the importance of nozzle tips, pressure, nozzle spacing and angle, optimum spray particle size in getting the greatest coverage at lower levels of the soybean canopy. A list of important bibiliography is included at the end of the each chapter to assist the readers in enriching their knowledge on fungicides. Preface XI This volume will be useful source of information on fungicides for post graduate students, researchers, agriculturists, environmentalists and decision makers. I am very much thankful to the contributors for their excellent articles. I am also grateful to InTech Publisher for their concern, efforts and encouragement in the task of publishing this volume.
