“…In this study, T. phayaoense could tolerate the selected fungicide (metalaxyl) in the field at recommended dosages. Similar to our results, previous studies have shown that T. atroviride, T. harzianum, T. koningii, and T. pseudokoningii have been acknowledged for their ability to tolerate fungicides, herbicides, and insecticides (Khan and Shahzad, 2007;Chaparro et al, 2011;Singh et al, 2012;Bhale and Rajkonda, 2015;da Silva et al, 2018). Additionally, the biocontrol agents of T. harzianum and T. virens could tolerate different insecticide compounds and could display varying degrees of tolerance (Wedajo, 2015).…”

Evaluation of a Newly Identified Endophytic Fungus, Trichoderma phayaoense for Plant Growth Promotion and Biological Control of Gummy Stem Blight and Wilt of Muskmelon

et al. 2021

Gummy stem blight and wilt are known to cause enormous losses to the global production of muskmelon (Cucumis melo). In this study, the potential of endophytic fungi isolated from leaves of Siam weed (Chromolaena odorata) was investigated for the inhibition of mycelial growth of Stagonosporopsis cucurbitacearum and Fusarium equiseti. Twenty-one fungal isolates were obtained. The results indicated that a fungal isolate UP-L1I3 displayed the highest percentage in terms of inhibition of the mycelial growth of F. equiseti and S. cucurbitacearum at 90.80 and 81.60%, respectively. Consequently, this isolate was selected for its potential ability to promote plant growth and control gummy stem blight and wilt in muskmelon seedlings. Morphological and multilocus phylogenetic analyses revealed that the isolate UP-L1I3 was a new species that has been described herein as Trichoderma phayaoense. Pathogenicity test confirmed that F. equiseti and S. cucurbitacearum were the cause of gummy stem blight and wilt disease in muskmelon seedlings, respectively. However, no disease symptoms were observed in seedlings inoculated with T. phayaoense. It was found that T. phayaoense could be used preventively in muskmelon seedlings that were inoculated with F. equiseti and S. cucurbitacearum, which could then reduce the impact on the disease severity index. T. phayaoense was also effective in improving plant development by increasing plant height, as well as shoot and root dry weight values. Moreover, T. phayaoense could effectively increase weight, diameter, and the circumference and total soluble solid of fruit without having a negative effect on fruit quality parameters. Additionally, T. phayaoense was able to tolerate a commonly applied fungicide (metalaxyl) in recommended dosages for field applications.

“…Fungicides of mankozeb and propineb have high growth inhibition in Trichoderma spp. However, previous studies under in vitro conditions have shown that when mancozeb is added to the culture medium in concentrations lower than 8 mg/mL, the mycelial growth of T. harzianum is not significantly inhibited [32]. Mancozeb was found highly compatible with T. harzianum in vitro and comparatively safer against T. harzianum as compared to other fungicides [33,34].…”

Chemical control is still a mainstay for some farmers in shallot center areas such as in Brebes, Central Java. Applications of fungicides that are carried out in these areas are very intensive and are carried out periodically every 3-5 days. The application of fungicides that are too intensive can certainly have a negative impact on functional microbes including biological disease control agents. The purpose of this study was to evaluate the negative impact of the application of several brands of fungicides on the efficacy of T. harzianum as a biological control agent for red onion mole. Experiments were carried out in the field and in the laboratory. The results of the field experiment showed that the combined application of T. harzianum and fungicide did not increase the efficacy of a single application. While the results of laboratory tests with application doses in the field can inhibit the growth of colonies and germination of T. harzianum. Brand-B with active ingredients Carbendazim 12% and Mancozeb 63% can inhibit colony growth and germination 100%.

“…Hefnawy et al (2014) found that T. harzianum and T. koningii combined with low dose of Rizolex T 50% increased the inhibition percentages of pathogenic fungi and may be beneficial in controlling soil-borne fungi. Bhale and Rajkonda (2015) reported that T. viride, T. harzianum, T. koningii, and T. virens were compatible to fungicides viz., Mancozeb and Captan at lower concentrations. Also, Wedajo (2015) reported that by increasing the fungicide concentrations to 400 ppm (sancozeb) and 600 ppm (curzate), T. harzianum and T. viride tolerate the fungicides 50% and slightly incompatible at higher concentrations of 800 and 1000 ppm, and completely inhibited beyond 1000 ppm, compared to the control for both fungicides.…”

Field application of Trichoderma spp. combined with thiophanate-methyl for controlling Fusarium solani and Fusarium oxysporum in dry bean

2019

Background: Damping-off and root rot/wilt diseases caused by the soil-borne fungi Fusarium solani and F. oxysporum are a serious problem of dry bean productions in Egypt. This study examines the potential of controlling these diseases biologically by using three Trichoderma isolates, compatible with the fungicide thiophanatemethyl, i.e., T. harzianum, T. viride, and T. virens. Soil application with inoculants containing these isolates employed either alone or in combination with seed coating with thiophanate-methyl was applied. Results: Under greenhouse and field conditions, all treatments significantly reduced the incidence of damping-off and root rot/wilt diseases and increased the percentage of survival plants. These treatments increased vegetative growth parameters and yield components of the survival dry bean plants compared with untreated control. Soil application with Trichoderma isolates combined with thiophanate-methyl seed treatments was more effective than using both of them individually. Meanwhile, T. virens + thiophanate-methyl was the most effective treatment. The tested treatments stimulated systemic defense responses in dry bean plants by activating defense enzymes including peroxidase, polyphenoloxidase, and chitinase. Conclusions: Based on the obtained results, compatible isolates of Trichoderma spp. as soil treatment combined with thiophanate-methyl as seed treatment may have potential to develop a new biofungicide for integrated management of damping-off and root rot/wilt diseases in dry bean.
