The problem of arsenic pollution of groundwater used for domestic water supplies is now well recognized in Bangladesh, India and some other countries of South and South-east Asia. However, it has recently become apparent that arsenic-polluted water used for irrigation is adding sufficient arsenic to soils and rice to pose serious threats to sustainable agricultural production in those countries and to the health and livelihoods of affected people.

Many plant diseases that are caused by soil borne pathogens can be difficult to predict, detect and diagnose. Investigations into these pathogens are further limited by the nature of the soil environment, which is extremely complex. Fungal pathogens are perhaps the most common type of soil borne plant pest. This makes gaining an understanding of soil borne plant pathogens, and the diseases they cause, a challenging aspect of plant bio-security.

Toxic effect of heavy metal on legume with reference to disease is poorly understood. These metals can arrest the growth of the plant that in turn limits the various metabolic activities of legumes including photosynthesis, synthesis of proteins, enzymes, and carbohydrates thus affect the legume yields severely. Therefore, this study focuses mainly on the two aspects (i) response of legumes under metal stressed environment and (ii) strategies to manage heavy metal, which may help in assessing the economic and ecological significance of metal.
