“…Trichoderma harzianum has been reported to inhibit growth of C. truncatum , causal pathogen of strawberry anthracnose [ 48 ], and mango anthracnose [ 49 ]. So far, there are no reports on antagonistic activity of T. koningiopsis against anthracnose pathogens, but this species has strong antagonistic activity against F. oxysporum , Rhizoctonia solani , and Botrytis cinerea that infected tomato and cucumber seedlings [ 50 ]. Trichoderma koningiopsis was also reported as strong antagonistic fungus, showing 85% growth inhibition of Calonectria pseudonaviculata causing blight of boxwood plant [ 51 ].…”

Calamus castaneus is a common rattan palm species in the tropical forests of Peninsular Malaysia and is noticeable by the yellow-based spines that cover the stems. This study aimed to determine the prevalence of fungal endophytes within C. castaneus spines and whether they inhibit the growth of fungal pathogens. Twenty-one genera with 40 species of fungal endophytes were isolated and identified from rattan palm spines. Based on molecular identification, the most common isolates recovered from the spines were Colletotrichum (n = 19) and Diaporthe spp. (n = 18), followed by Phyllosticta spp., Xylaria sp., Trichoderma spp., Helminthosporium spp., Penicillium spp., Fusarium spp., Neopestalotiopsis spp., Arthrinium sp., Cyphellophora sp., Cladosporium spp., Curvularia sp., Bionectria sp., and Acremonium spp. Non-sporulating fungi were also identified, namely Nemania primolutea, Pidoplitchkoviella terricola, Muyocopron laterale, Acrocalymma fici, Acrocalymma medicaginis, and Endomelanconiopsis endophytica. The isolation of these endophytes showed that the spines harbor endophytic fungi. Most of the fungal endophytes inhibited the growth of several plant pathogenic fungi, with 68% of the interactions resulting in mutual inhibition, producing a clear inhibition zone of <2 mm. Our findings demonstrate the potential of the fungal endophytes from C. castaneus spines as biocontrol agents.

“…In this study, the antagonistic activity of 15 unidentified Trichoderma isolates was evaluated in vitro and in vivo against 4 strains of F. culmorum, common causative agents of FCR and FHB in wheat. Trichoderma is a nonpathogenic fungus that provides protection to many crops against fungal diseases caused by the genus Fusarium (Tsegaye Redda et al 2018). It is used as a biocontrol agent, avoiding the adverse effects that accompany chemical control.…”

Background Durum wheat (Triticum durum Desf.) is one of the most important cereals in the world. Unfortunately, the wheat plant is a target of several species of the genus Fusarium. This genus causes two serious diseases: fusarium crown rot (FCR) and fusarium head blight (FHB). The search for new indigenous strains of Trichoderma with a high potential for biocontrol against these two diseases was the purpose of this study. Results Biocontrol potential of 15 isolates of Trichoderma (T1 to T15), isolated from different rhizosphere soils and Algerian ecosystems, was evaluated against 4 strains of Fusarium culmorum (FC11, FC2, FC4, and FC20); the main causative agent of FCR and FHB. The efficacy of biological control by Trichoderma spp., evaluated by in vitro tests (direct and indirect confrontation), was confirmed by in vivo bioassays. The in vitro results showed a significant inhibition of mycelial growth of F. culmorum species than the control. The highest percentages of inhibition were obtained by T9, T12, and T14 isolates causing a maximum inhibition percentage of 81.81, 77.27, and 80.68%, respectively. T14 was selected for biocontrol in in vivo testing. A tube and pot experiments for FCR against F. culmorum showed that T14 decreased the disease severity with 50 and 63.63% reduction, respectively. FHB infection was significantly reduced by T14 in all durum wheat cultivars tested, where %AUDPC (area under the disease progress curve) reduction was 49.77, 43.43, 48.25, and 74.60% for Simeto, Waha, Bousselem, and Setifis genotypes, respectively. Yields also increased significantly for almost all cultivars. The antagonistic T14 was characterized based on molecular tools, using translation elongation factor1-alpha (TEF1-α) and internal transcribed spacers rDNA (ITS1). The results identified T14 as T. afroharzianum with accession numbers attributed by NCBI GenBank as MW171248 and MW159753. Conclusions Trichoderma afroharzianum, evaluated for the first time in Algeria as biocontrol agent, is a promising biocontrol approach against FCR and FHB.

“…Similar results were reported by Wharton et al 2012 on Bacillus substilis and T. harzianum in managing late blight through seed treatment by slice piece. Recently Carrero-carr et al (2016) and Redda et al (2018) found that T. asperellum could suppress Verticillium wilt and fusarium wilt, botrytis and Rhizoctonia respectively. Moreover Viterbo et al (2010) reported that T. asperellum promoted plant growth when inoculated on the seed.…”

“…Trichoderma is a fast growing fungi that manage crop diseases by competition, use of cell degrading enzymes and inducing systemic resistance in crops (Janzen, 2011) and stimulate plant immunity as well promote plant growth (Keswani et al, 2014). It is widely studied biocontrol due to its mycoparasitic action against many plant pathogens including Pythium species in vitro (Hermosa et al, 2011), Fusarium species (Abhiram & Masih, 2018), Rhizoctonia and Botrytis species (Redda et al, 2018). In addition, the biocontrol has been reported to enhance plant growth (Viterbo et al, 2010).…”

Fungicides overuse in management of late blight has led to increased cost of production and biodiversity issues. To better understand costs and benefits associated with seed treatment to reduce fungicide application, apical cutting and tuber seed crop were pre-treated by either peridermal injection or dipping using T. asperellum suspension at 33%, 66% and 100% concentration and then sprayed separately with Ridomil® (Metalaxyl 4% + Mancozeb 64%) at 21, 14 and 7 (Manufacturer’s Recommended Regime) days interval. Results showed that apical cuttings had 7.5% higher disease severity and 0.2% lower yield than crop from seed tuber. Untreated and 33% T. asperellum were not significant different (p = 0.05) in disease and yield scores. T. asperellum concentration at 66% and 100% reduced disease severity by 26% and 27% resulting to 30% and 29% yield increment respectively. Spray interval of 14 days did not differ significantly from 7 day spray interval in terms of disease score and yield but the regime MRR% was double 7 day spray interval. Maximum yield loss was observed in unprotected plots followed by treatments sprayed at 21 days interval. Combination of 66% and 100% T. asperellum concentration with 14 days interval resulted to higher yield and marginal rate of return compared to any other combination. Seed dipping was four times profitable than injection. The findings suggest that seed treatment at 66% and 100% T. asperellum concentration by dipping in combination with Ridomil® application at 14 days interval significantly reduced late blight epidemics and improved on yield and consequently increased net farm income.
