Diseases caused by Fusarium solani are very common and occur world wide. Control of pathogenic fungi has become an obligatory requirement. Chemical control is the most commonly used but the biological control being the most popular way of controlling the pathogenic fungi. Natural plants products are biodegradable, exhibit structural diversity and complexity and used traditionally to treat a number of infectious diseases including those caused by bacteria, fungi, protozoa and viruses. On the basis of efficacy of plant extracts, present study has been designed to find out the effective plant product for the management of F. solani by using Parthenium hysterophorus and molecular characterization of Fusarium solani.

Biological control is an approach that provides safe fungal management program, and corresponds to a substitute for reliance on chemical treatment methods. It is often used to gradually suppress widespread infestations in low value or remote areas where other methods are not feasible. Natural plants derived compounds contribute a lot in fight against pathogens.Numerous studies conducted in Pakistan revealed a wide spectrum prospects of using extracts of plants for biological control of pathogenic fungi. On the basis of efficacy of plant extracts, present study has been designed to find out the effective plant product to control Alternaria alternata in vitro by using medicinal plant, Tagetus errectus, and molecular characterization of Alternaria alternata.

Cellulose has attracted considerable interest as a renewable resource since bioconversion products have potential value in food and chemical industries and as an energy source. As million of tons of cellulose squandered annually, fungi can prove a constructive device by producing cellulases in recycling of polymeric carbohydrates, otherwise being locked inside the waste products. Cellulase is a group of enzymes responsible for cellulose degradation. Its application can be seen in animal feed, pharmaceutical, textile and paper and pulp industry. The utilization of fungal biomass for cellulose degradation at industrial scale is increasing all over the world as economically feasible. The present study, therefore, was designed to evaluate the bioactivity of known cellulolytic fungal species to screen and select the best potential candidates. Selected species were subjected to UV and chemical mutagens for prospective evolution of high yielding strains. Further strain conditioning was carried out on economically feasible substrate to evolve commercially viable technology for celluiase enzyme production.

Amylase is an enzyme that hydrolyses starch for the production of ethanol and fructose. It has many applications in today's market place. In industry, it is very advantageous to find organisms that can produce specific enzymes. Fungi being potential source of enzymes with scientific and commercial interests have a great potential to degrade polysaccharide constituents of starch. The present study was, therefore, designed to screen efficient species of fungi from already reported amylase enzyme producers. The isolates expressing maximum efficiency were exposed to UV and chemical mutagens to further enhance their enzyme production potential. Comparative bioactivity assays of mutants obtained were carried out to select the high yielding strains. Growth of potential strains was conditioned on agri-wastes products to evolve economically feasible technology for amylase production to meet industrial sector demand.
