“…feature predominantly as a competent biological control agent against a wide variety of phytopathogenic organisms. Similar traits are also exhibited against mycotoxigenic fungi and subsequent mycotoxin production (Braun et al., ; Saravanakumar et al., ; Veenstra, Rafudeen, & Murray, ). Prevalently found in the rhizo‐ and phyllosphere, the free‐living and fast‐growing Trichoderma spp.…”

In this review, we present the current information on development and applications of biological control against phytopathogenic organisms as well as mycotoxigenic fungi in Malaysia as part of the integrated pest management (IPM) programs in a collective effort to achieve food security. Although the biological control of phytopathogenic organisms of economically important crops is well established and widely practiced in Malaysia with considerable success, the same cannot be said for mycotoxigenic fungi. This is surprising because the year round hot and humid Malaysian tropical climate is very conducive for the colonization of mycotoxigenic fungi and the potential contamination with mycotoxins. This suggests that less focus has been made on the control of mycotoxigenic species in the genera Aspergillus, Fusarium, and Penicillium in Malaysia, despite the food security and health implications of exposure to the mycotoxins produced by these species. At present, there is limited research in Malaysia related to biological control of the key mycotoxins, especially aflatoxins, Fusarium‐related mycotoxins, and ochratoxin A, in key food and feed chains. The expected threats of climate change, its impacts on both plant physiology and the proliferation of mycotoxigenic fungi, and the contamination of food and feed commodities with mycotoxins, including the discovery of masked mycotoxins, will pose significant new global challenges that will impact on mycotoxin management strategies in food and feed crops worldwide. Future research, especially in Malaysia, should urgently focus on these challenges to develop IPM strategies that include biological control for minimizing mycotoxins in economically important food and feed chains for the benefit of ensuring food safety and food security under climate change scenarios.

“…Most of the strains are rarely cause diseases in living plants. Among different species, T. harzianum is recognized for its antagonist ability against various fungal pathogens, and largely exploited in disease control [40]. The key biocontrol genes of T. harzianum, such as tris5, ThpG1, Th-Chit, erg1, thkel1 and qid74, are related to stress resistance, cell wall damaging, mycelial development, and parasitic activity [41] [42].…”

Major pathogens causing fruit rots of apple in shelf life in Hangzhou, a city in east China, were identified by rDNA-ITS analysis. Their pathogenicities and stress tolerances were compared as well. Combining with disease symptoms, colonial phenotypes and mycelial microscopic morphology, the fungi were determined as Penicillium expansum, Botrytis cinerea, Botryosphaeria dothidea, Diaporthe phaseolorum, Alternaria alternata and Fusarium acuminatum, respectively. Among them, B. cinerea and B. dothidea showed a higher pathogenicity; B. cinerea and D. phaseolorum were hardly affected by the temperature at a range of 15˚C and 25˚C; B. cinerea has the highest resistant to Thiabendazole and D. phaseolorum displayed the strongest resistance to Imazalil; and P. expansum was most sensitive to ultraviolet light radiation. The results provide some useful information that helps to combine conventional and alternative control strategies to minimize apple postharvest losses in shelf life.

“…The production of extracellular enzymes was responsible for the inhibitory effect of T. viride on toxigenic A. flavus [43]. T. harzianum actively attached to the toxigenic Aspergillus species followed by enzymatic lysis of the mycelial filaments [117]. Such, mechanisms of the inhibitory actions against the growth of A. flavus by T. harzianum are strains-specific and mainly include (1) faster growth speed to compete for nutrients and living space, (2) mycoparasitism, and (3) the production of extracellular enzymes, deteriorating aflatoxigenic mycelia.…”

Aflatoxin contamination has been causing great concern worldwide due to the major economic impact on crop production and their toxicological effects to human and animals. Contamination can occur in the field, during transportation, and also in storage. Post-harvest contamination usually derives from the pre-harvest infection of aflatoxigenic molds, especially aflatoxin-producing Aspergilli such as Aspergillus flavus and A. parasiticus. Many strategies preventing aflatoxigenic molds from entering food and feed chains have been reported, among which biological control is becoming one of the most praised strategies. The objective of this article is to review the biocontrol strategy for inhibiting the growth of and aflatoxin production by aflatoxigenic fungi. This review focuses on comparing inhibitory behaviors of different antagonistic microorganisms including various bacteria, fungi and yeasts. We also reviewed the bioactive compounds produced by microorganisms and the mechanisms leading to inhibition. The key factors influencing antifungal activities of antagonists are also discussed in this review.
