Groundnut is infected by 55 pathogens which adversely contribute to the low yield of groundnuts. Three sub-trials were conceived to proffer solutions to groundnut Cylindrocladium parasiticum disease. These sub-trials (using biocontrol, synthetic and botanical measures) were set up in vitro using completely randomized design with each treatment replicated thrice. Firstly, all biocontrol (Trichoderma) isolates showed a steady linear increase in the inhibition of the growth of the pathogen. There was no significant difference (P≤0.05) between the isolates of Trichoderma harzianum at 96 h after inoculation (HAI). Secondly, the synthetic pesticide Mancozeb® 100% significantly inhibited the pathogen more than all other synthetic chemical treatments, followed by Mancozeb 50%, Tandem® 100% and Tandem 50% (which were at par (at 144 HAI)). Thirdly, the botanical Parkia sp. 100% was significantly superior to other botanicals (192 HAI results). Likewise, Casuarina sp. 100% and Parkia sp. 50% were at par but performed better than other treatments except for Parkia sp. 100%. Inhibition by Casuarina sp. 50% was at par with Parkia sp. 50% but it was significantly superior to other treatments (except for Parkia sp. 100%, Casuarina sp. 100%, and Parkia sp. 50%). Finally, all trials showed that Mancozeb 100% performed better than other treatments.

“…In addition, remarkably, antifungal activity against M. perniciosa and M. roreri has been found for foliar endophytic fungi [ 30 ] and endophytic Bacillus [ 31 ] isolated from cocoa cultivars. Additionally, T. spirale has been shown to inhibit the growth of Fusarium oxysporum during in vitro and greenhouse experiments, demonstrating the relevance of the metabolites produced by this strain, which also indicates plant protection against fungal disease [ 32 ].…”

“…Different findings have evidenced the growth restraint of M. roreri through T. harzianum (40.50–41.20%), T. ressei (20.30–25.80%) in Mexico [ 20 ], T. harzianum (75%) in Ecuador [ 27 ], and native Trichoderma strains (48.50–57.94%) in Peru [ 23 ]. Even so, M. roreri growth inhibition (25–97%) and growth stimulation (50–140%) ranges have been indicated by the fungicide flutolanil [ 32 ].…”

Chemical Characterization of Trichoderma spp. Extracts with Antifungal Activity against Cocoa Pathogens

Ecuador is one of the major cocoa producers worldwide, but its productivity has lately been affected by diseases. Endophytic biocontrol agents have been used to minimize pathogenic effects; however, compounds produced by endophytes are minimally understood. This work presents the chemical characterization of the Trichoderma species extracts that proved inhibition against cocoa pathogens. Solid–liquid extraction was performed as a partitioning method using medium with the fungal mycelia of Trichoderma reesei (C2A), Trichoderma sp. (C3A), Trichoderma harzianum (C4A), and Trichoderma spirale (C10) in ethyl acetate individually. The extract of T. spirale (C10) exhibited the growth inhibition (32.97–47.02%) of Moniliophthora perniciosa at 10 µg/mL, while a slight stimulation of Moniliophthora roreri was shown by the extracts of T. reesei (C2A) and T. harzianum (C4A) at higher concentrations. The inhibitory activity could be related to alkaloids, lactones, quinones, flavonoids, triterpenes, and sterols, as indicated by chemical screening and antifungal compounds, such as widdrol, β-caryophyllene, tyrosol, butyl isobutyrate, sorbic acid, palmitic acid, palmitelaidic acid, linoleic acid, and oleic acid, which were identified by gas chromatography–mass spectrometry (GC-MS). The results showed that the extracts, particularly T. spirale (C10), have the potential as biocontrol agents against witches’ broom disease; however, further studies are needed to confirm their effectiveness.

“…To circumvent these problems and increase the stability and efficiency of useful microorganisms introduced in the soil and rhizosphere, solutions based on combinations of BCAs, commonly called microbial consortia, consisting of two or more microbial strains, have been developed [52]. Recently, the design of microbial consortia is a major trend in biotechnology applied to the management of soil-borne diseases, and microbial communities consisting of separate application of prokaryotes [54,55] or fungi [56] or use of a mix of fungi and bacteria [57][58][59] are already available. Besides the natural microbiome, the application of selected mixtures of microorganisms has proven to be effective in biocontrol experiments [60,61].…”

Advances and Perspectives in the Use of Biocontrol Agents against Fungal Plant Diseases

et al. 2022

The use of synthetic fungicides to control fungal diseases has growing limitations due to eco-toxicological risks. Therefore, it is necessary to replace or integrate high risk chemicals with safer tools for human health and environment. Consequently, research on the selection, evaluation, characterization, and use of biocontrol agents (BCAs) has consistently increased in the last decades. BCA formulates, particularly in some countries, are still scarce in coping with the growing demand for their use in sustainable agricultural management. To foster development and utilization of new effective bioformulates, there is a need to optimize BCA activity, to share knowledge on their formulation processes and to simplify the registration procedures. Studies based on new molecular tools can significantly contribute to achieve such objectives. The present review provides the state of the art on biocontrol of fungal plant diseases with special emphasis on (i) features of the most studied BCAs; (ii) key strategies to optimize selection and use of BCAs (iii); mechanisms of action of the main BCAs; (iv) molecular tools and metagenomic studies in the selection and use of BCAs; (v) main issues and constraints in the registration and commercialization of BCAs, and (vi) perspectives in the biocontrol of fungal plant diseases.
