Abstract
Antagonistic Efficiency of Aspergillus giganteus as a Biocontrol Agent against Aflatoxigenic Aspergillus flavus Infecting Maize
Highlights
Plant diseases are caused by numerous organisms such as fungi, oomycetes, bacteria, viruses, protozoa, nematodes and so on
The antagonism can be ranked as class 1, as there was complete overgrowth of A. giganteus over A. flavus with competition for space and nutrients (Fig. 1)
A similar study conducted by Madbouly et al.[25] using bioassays such as dual culture proved that Penicillium crustosum, Aspergillus giganteus, Fusarium verticillioides and Aspergillus fumigatus isolates had promising antifungal activities against pathogenic fungi
Summary
Plant diseases are caused by numerous organisms such as fungi, oomycetes, bacteria, viruses, protozoa, nematodes and so on. The most destructive and deleterious plant diseases are caused by fungal pathogens producing toxins which cause heavy losses in the crop production levels[1]. The most dreaded challenge is to control the mycotoxigenic fungi to tackle issues of food safety as over 25% of the global food and feed crops are affected by accumulation of mycotoxins[2,3,4]. Corn is a major staple crop which is more often affected by Aspergillus species, predominantly by A. flavus and A. parasiticus which contaminate the kernels by producing aflatoxins which are highly carcinogenic[5]. The crops are prone to contamination during the preharvest stages and storage conditions where the environmental factors play a major role[6]. Sustainable management of infectious Aspergilli has ever since been a necessity to control aflatoxin related health issues
