This is an enumeration of the seed plants (excluding monocots) found in tropical Singapore. It includes nearly 1,300 species of naked-seeded plants and dicots which are native or naturalised, and over 520 species which are commonly cultivated in Singapore and adjacent islands. They are systematically arranged in 142 families in this book. An alphabetical list of the families can be found in the beginning of the book. There are brief descriptions on the families and short diagnoses and notes to the species of the genera. Keys to the families and genera of most families are also provided. Nearly all the families are illustrated with at least one line drawing. Some of the larger families, such as composites and legumes, are accompanied with 10 to 20 drawings. They generally depict the common or renowned examples.

This volume focuses on integrated pest and disease management (IPM/IDM) and biocontrol of some key diseases of perennial and annual crops. It continues a series originated during a visit of prof. K. G. Mukerji to the CNR Plant Protection Institute in Bari (Italy), in November 2005. Both editors aim at a series of five volumes embracing, in a multi-disciplinary approach, advances and achievements in the practice of crop protection, for a wide range of plant parasites and pathogens. Two volumes of the series were already produced, dedicated to general concepts in IPM and to management and biocontrol of nematodes of grain crops and vegetables. This Volume deals, in particular, with diseases due to bacteria, phytoplasma and fungi. Every day, in any agroecosystem, farmers face problems related to plant diseases. Since the beginning of agriculture, indeed, and probably for a long time in the future, farmers will continue to do so. Every year, plant diseases cause severe losses in the global production of food and other agricultural commodities, worldwide. Plant diseases are not limited to episodic events occurring in single farms or crops, and should not be regarded as single independent cases, affecting only farms on a local scale. The impact of plant disease epidemics on food shortage ignited, in the last two centuries, deep cultural, social and demographic changes, affecting million human beings, through i. e. migration, death and hunger.
