Abstract

The phytopathogenic fungi are now approaching their 3rd century, being most economically important mainly associated with wide variety of plants and plant-derived products. They are also prevalent seed-borne fungi associated with cereals intended for human and animal consumption throughout the world causing variety of diseases in plants, humans, and animals. Phytopathogenic fungi such as species of Fusarium, Aspergillus, Puccinia, Penicillium, Alternaria, Curvularia, and Cladosporium attack cereals like rice, wheat, maize, barley, and sorghum grains which are of worldwide importance in agricultural field. Currently, the idea of controlling soil-borne pathogens with chemical pesticides or fungicides is being challenged using biological control that plays an important role in sustainable agriculture. Vital criteria for current biocontrol, microorganisms with the ability to colonize the infected plant part under appropriate environmental conditions and compatibility are applied. Biological-based methods for control of phytopathogenic fungi harming cereal crops could have potential commercial applications. Simple and practical intervention strategies could also impact positively on food safety and security especially in rural populations reliant on cereals as a dietary staple has attracted attention throughout the world. The elimination of the growth of toxigenic phytopathogenic fungi in the cereals and cereal-based food products is of paramount importance because of their secondary metabolite production which can be carcinogenic, mutagenic, teratogenic, estrogenic, neurotoxic, immunotoxin, etc. Currently probiotics and PGPR-based biofertilizers serve as a good biocontrol agent against phytopathogenic fungi associated with cereals. Even though vast application is in biological control methods, huge energy is implicated on controlling phytopathogenic fungal growth and its effects in vitro and further the knowledge should be developed in applying it in plants and field both in pre and postharvest of storage processing.
