Chaetomium globosum: A potential biocontrol agent and its mechanism of action
2015
AGGARWAL, RASHMI
India with diverse soil and climate comprising several agro-ecological regions provides ample opportunity to grow a variety of crops and these crops form a significant part of total agricultural production in the country. More than 70% of all major crop diseases are caused by fungi. These pathogens perpetuate through seed, crop residue and soil. Considering the nature of the disease, control measures are directed towards host resistance and fungicidal control. Breeding for disease resistance has also been not successful in many cases due to non-availability of sources of resistance. Chemical control measures have shown promise but are not considered economical and eco-friendly. Since their large-scale use has been responsible for the undesirable effects such as persistence, bioaccumulation, biomagnification, toxicity, pathogen resistance, secondary pest outbreak and destruction of the non-target organisms, these have necessitated looking for alternative approaches, such as biological control.
