This book provides the traditional as well as modern analytical techniques used for sample preparation of different matrices for extraction, clean-up, detection and estimation of pesticide residues in soil, water and food commodities.

This Book deals with identification of flowering plants (Angiosperms). The book has been divided into 12 chapters and identification & classification are mainly based on Bentham and Hooker¿s system. A detailed account of Natural system of classification has been incorporated in chapter 3. Identification keys of Families, Genera and species given in details which would be very helpful for students. Besides these some taxonomic literature and taxonomic terms have also been highlighted as points to remember.

This book provides the traditional as well as modern analytical techniques used for sample preparation of different matrices for extraction, clean-up, detection and estimation of pesticide residues in soil, water and food commodities. It touches some aspects of most extraction cum clean-up techniques known as Quenchers methods. Brief history of pesticide development, modern pesticides and metabolic pathway of selected xenobiotics from different group of pesticides, imparts information on basic nature of pesticides. The book discusses latest analytical techniques like TLC, GLC, HPLC, HPTLC, super critical extraction and chromatography in simple but vivid manner. The sampling extraction, clean-up and solid phase extraction technique for residue analysis has been explained in the detail. Recently developed multi-residue methods have been outlined in a separate . Help from a number of standard reference books and research papers have given it a modern touch. Additionally a containing glossary of pesticide residue terms can be extremely helpful for a beginner in this fields. The book will provide students with sufficient background for the pesticides, their metabolism and above all various techniques for the estimation of residues of the toxic xenobiotics in all components of the environment. In short the book offers an excellent readable material for a knowledge seeker, may be a student or a research worker. It is that the book will prove highly valuable to all those who are engaged in the area of pesticides."

The book is intended to provide a clear overview on the management of pests and diseases of horticulture crops, associated soil and beneficial fauna, residue status of pesticides and their estimation techniques. It is divided in four parts: Part I explain the practices followed in the pest management of horticulture crops. s include pest status of insects, mites, rodents, and diseases in fruits, vegetables, ornamentals, spices and mushrooms and their management. Different aspects of biological, cultural, and mechanical controls are also highlighted. Harmful and beneficial soil fauna associated with horticulture crops are dealt in Part II. Keeping in view the potential of beneficial organisms, the effects of pesticides on predators, parasites and pollinators have also been discussed in this section. The recent scientific developments related to residue status in vegetables, fruits and spices are provided in Part III. Part IV includes the residue estimation techniques of various pesticides.
