Nagoya Protocol and Africa’s willingness to share biological control agents, are we deterred by barriers instead of using opportunities to work together?

Amongst members of the biological control community there is a range of perceptions regarding the Nagoya Protocol, at best it will hinder access to natural enemies of pests and invasive plants and at worst implementation of the Protocol will …

Inhibitory effect of volatile organic compounds from Bacillus flexus TR-1 against Aspergillus flavus and aflatoxins in grains during storage

Aspergillus flavus infects stored grains and produces aflatoxins with highly toxic and carcinogenic properties, which are a threat to food safety and human health. Microbes and their bio-active compounds are considered effective agents to control …
