“…Trichoderma has been shown to be an effective fungus in combating crop diseases caused by Bipolaris oryzae, Meloidogyne javanica and Rhizoctonia solani , which affect crops such as rice, tomatoes, and potatoes (Hariharan et al, 2022 ; Mukherjee et al, 2022 ). It produces active secondary metabolites such as anthraquinones, cyclopentenone, ergosterol derivatives, and N-heterocyclic compounds, which are effective against these crop pathogens (Meena et al, 2020 ; Scudeletti et al, 2021 ; Verma et al, 2021 ).…”

As the global human population continues to grow, the demand for food rises accordingly. Unfortunately, anthropogenic activities, climate change, and the release of gases from the utilization of synthetic fertilizers and pesticides are causing detrimental effects on sustainable food production and agroecosystems. Despite these challenges, there remain underutilized opportunities for sustainable food production. This review discusses the advantages and benefits of utilizing microbes in food production. Microbes can be used as alternative food sources to directly supply nutrients for both humans and livestock. Additionally, microbes offer higher flexibility and diversity in facilitating crop productivity and agri-food production. Microbes function as natural nitrogen fixators, mineral solubilizers, nano-mineral synthesizers, and plant growth regulator inducers, all of which promote plant growth. They are also active organisms in degrading organic materials and remediating heavy metals and pollution in soils, as well as soil-water binders. In addition, microbes that occupy the plant rhizosphere release biochemicals that have nontoxic effects on the host and the environment. These biochemicals could act as biocides in controlling agricultural pests, pathogens, and diseases. Therefore, it is important to consider the use of microbes for sustainable food production.

“…Entomopathogenic fungi (EPF) represent a promising sustainable alternative to chemical pesticides and have been used against a broad range of agricultural and forest insect pests (Ocampo-Hernández et al, 2011;Verma et al, 2021). Their use is particularly interesting for the control of ambrosia beetles, as the cryptic nature of these insects effectively protect them from conventional insecticides during most of their life cycle (Castrillo et al, 2016).…”

Ambrosia beetles and their symbiotic fungi are causing severe damage in natural and agro-ecosystems worldwide, threatening the productivity of several important tree crops such as avocado. Strategies aiming at mitigating their impact include the application of broad-spectrum agrochemicals and the incineration of diseased trees, but the increasing demand for environment-friendly strategies call for exploring biological control for the management of ambrosia beetles and their phytopathogenic fungal symbionts. The aim of this review is to examine the existing knowledge on biocontrol approaches using beneficial microorganisms and microbial natural products with entomopathogenic and antifungal activity against ambrosia beetles and fungi. We show that biocontrol has been mainly focused on the insect, using entomopathogenic fungi (EPF) such as Beauveria spp. or Metarhizium spp. However, recent studies have been integrating EPF with mycoparasitic fungi such as Trichoderma spp. to simultaneously challenge the vector and its fungal symbionts. Novel approaches also include the use of microbial natural products as insect lures or antifungal agents. Contrastingly, the potential of bacteria, including actinobacteria (actinomycetes), as biocontrol agents of ambrosia fungi has been little investigated. We thus suggest that future research should further examine the antifungal activity of bacterial strains, with an emphasis on harsh environments. We also suggest pursuing the isolation of more effective microbial strains with dual biocontrol effect, i.e., exhibiting fungicidal/insecticidal activities. Moreover, additional efforts should aim at determining the best application methods of biocontrol agents in the field to ensure that the positive effects detected in vitro are sustained. Finally, we propose the integration of microbiome studies in pest and disease management strategies as they could provide us with tools to steer the beneficial host plant microbiome and to manipulate the beetle microbiome in order to reduce insect fitness.

“…Sulfur fungicides prevent the spread of fungal spores, and copper ions kill the fungus by denaturing the enzymes and proteins in pathogen cells. Although the sulfur- and copper-based fungicides have been effective in minimizing the spread of Alternaria leaf spot, they irritate the applicants' eyes and skin, can cause bodily harm if ingested, and also pollute the environment [ 8 ].…”

Phaseolus vulgaris L. is considered one of the most essential legume crops in Kenya. Alternaria alternata is an economically significant plant pathogen that causes Alternaria leaf spot which accounts for over 70% yield losses of beans in Kenya. Chemical fungicides based on copper and sulfur are used to control Alternaria leaf spot in bean plants, but their prolonged use has adversely affected the environment and the health of workers. Herein, we tested the biocontrol potential of bacterial agents from soil planted with Rosecoco bean plants infected with A. alternata. Using bacterial suspensions at different time intervals, we evaluated the putative bacterial biocontrol activity against A. alternata under greenhouse conditions. B. subtilis and B. velezensis bacterial biocontrol agents significantly suppressed disease severity by 20% and 21.2% on the 45th day, respectively. Our study demonstrates that B. subtilis and B. velezensis are promising biocontrol agents that could be integrated in the management of Alternaria leaf spot.
