Study on biocontrol aspect of potential Alcaligenes faecalis against Fusarium sp.,Concept and Approach

Abstract

The world is dealing with vivid pollutions which lead to the degradation of resources and human health. In soil, the yield of crops is enhanced by the rampant use of chemical pesticides and fertilizers. The fungicides are applied on a large scale on almost all crops to control fungal infection which is the primary cause of crop productivity loss globally. The chemical fungicides are nevertheless causing great harm to soil quality and human health as many fungal pathogens are resistant to these chemical fungicides and all applied in bulk. There is a huge need for the substitution of such fungicides by natural components. The work is just an attempt in this aspect only to glorify Alcaligenes faecalis as a natural substitute for chemical fungicides as its bio- remediating aspect is explored earlier. The least explored association of Alcaligenes faecalis with Fusarium sp. which could be a futuristic fungicide is represented. Fusarium sp. (mainly Fusarium oxysporum and Fusarium incarnatum) are quite pathogenic causing great loss to various plants and crops across the globe. They are altogether responsible for wilt, leaf spot and root rot diseases. Alcaligenes faecalis as a potent biocontrol agent is introduced here as this bacterium has plant growth- promoting features too. So, Alcaligenes faecalis could become a natural, futuristic and biological fungicide and fertilizer. The large-scale bioinoculant production with its specific carrier molecules needs to be explored.
