While the antifungal efficacy of S. sporoverrucosus B-1662 is highlighted, the potential phytotoxic effects of the bacterial culture or its metabolites on the treated plants are not evaluated. Such assessments are crucial for ensuring the safety of this biocontrol agent in agricultural applications.
The study attributes the biocontrol activity to secondary metabolites like dibutoxybutane, yet the precise mode of action remains speculative. For example, how does dibutoxybutane inhibit fungal growth at the cellular or molecular level? A mechanistic exploration would significantly strengthen the study’s conclusions.
The research focuses on short-term disease control outcomes but does not address the long-term sustainability of using S. sporoverrucosus B-1662. For instance, does repeated application lead to resistance development in target pathogens, or does it affect the broader soil microbial community?
