Roots Metal Pollution due to various Industrial and agricultural activities is causing serious threat both to terrestrial and aquatic ecosystems. Some of these Metals are essential as trace elements but they become toxic when their concentration exceeds certain level. Certain microbes and Plants detoxify metabolically such pollutants and may reduce the vulnerability of such heavy metals. Various anthropogenic activities like mining, smeltering, disposal of wastes excessive use of Pesticides and Fertilizers etc. enhance the metal toxicity affecting the growth and Productivity of Agriculture and forestry.
In recent past heavy metal toxicity has been studied at genetic, biochemical, Physiological and Molecular levels both in laboratory and in contaminated environment. Mycorrhiza, ubiquitous symbiotic association between Fungi and Roots of Higher plants constitute an important functional component of Soil ecosystem. The Positive role of mycorrhiza in nutrient uptake and Improving Crop has shown that mycorrhizal fungi also improve tolerance of plants to heavy metals and provide them better support to overcome abiotic stress caused by heavy metals. This book provides critical Research analysis on the role of mycorrhiza on microbial enzymes, improvement of growth of seedling under heavy metal polluted soil and the possible mechanism of detoxification of heavy metals by microbes, mycorrhiza and plants.
We are quite hopeful that book will be very useful to the teachers, researchers and post-graduate students involved in studies related to agriculture, forestry, botany, Environmental sciences and microbiology.

GRAIN early Neandethal man, weeds have been Used for food, feed and Healing purposes. The Knowledge on the subject has descended through generations and has survived through Times among some of the primitive tribal people. Ethnobotany in a specialised branch of Botany that deals with food, feed, Medicinal and other were of wild Plants and weeds. In olden days, the subject of human suffering and its alleviation was closely also dated with religion, Magic and myth. Though ancient knowledge is valuable but need to by scientifically tested.
The book covers more than one hundred seventy herbs, most of which are readily available in Paddy Fields and bunds. It describes the food, feed pharmacentical and other uses of Rice Weed found in arable, swampy, shallow water, deep Water ecosystems. The distinchre feature of the book is its reasonably comprehensive information about the habit, habitat, morphological description, occurrence and ethnobiological value of prominent weeds present in South Asia.
It is an indispensable book for every researcher, teacher, planner, and students to strengthen the Agriculture and food security. Based on his own work over the number of years and that of others before him, The Author presents in this book ethnobiological value of rice weeds in Asia with illustrations. The book fulfills a long-felt need of ethnobiology of rice weeds in Asia.
