Magnaporthe grisea is the causal agent of rice blast disease, which is the most serious disease of cultivated rice. Aromatic polyketides are its typical metabolites and are involved in the infection process. In the search for novel lead compounds, chemical investigation of the fungus M. grisea M639 has led to the isolation of four new aromatic polyketides (salicylaldehyde skeleton bearing an unsaturated side chain), griseaketides A–D (1–4), as well as 15 known compounds (5–19). The structures of the new compounds were elucidated on the basis of extensive spectroscopic analyses, including HR-MS, 2D NMR. Compound 12 showed prominent activity that killed 94.5% of C. elegans at 400 ppm and 66.9% at 200 ppm over 24 h. This is the first report describing the nematicidal activity of this type aromatic polyketide.

“…However, the genus Trichoderma also has potential to control plant-parasitic nematodes (Sahebani and Hadavi, 2008;Yang et al, 2010). Simultaneously, several reports have indicated that T. harzianum induced systemic resistance in the plant challenged with fungal and bacterial pathogens (Harman et al, 2004;Singh et al, 2016a, b).…”

The aim of the study was to evaluate the biocontrol potential of Trichoderma harzianum against Meloidogyne incognita and decipher mechanisms of induced systemic resistance and disease suppression in tomato grown in net house conditions. The fungal biocontrol agent T. harzianum UBSTH-501 was evaluated against M. incognita on dual plate under in vitro conditions and in planta under nethouse conditions. The results of in vitro parasitism on dual plates showed that T. harzianum causing infection on the eggs and juveniles of root-knot nematode, whereas, in planta assay showed that plants treated with talc based bioformulation T. harzianum UBSTH-501 exhibited manifold increase in the accumulation of total chlorophyll and enzymes, viz. chitinase, phenylalanine ammonia lyase (PAL) and peroxidase which is known to confer systemic resistance in tomato against M. incognita resulting into decreased nematode population and disease severity. Results revealed that T. harzianum UBSTH-501modulated phenylpropanoid pathways led to enhanced accumulation of defence related mediator molecules and enzymes in tomato resulted in disease suppression to a significant extents.

“…Many studies demonstrated that Trichoderma spp. can inhibit growth or kill soil borne pathogens and revealed different antagonistic interactions between the antagonist Trichoderma and the pathogen in vitro and in vivo (Lumsden et al, 1993;Monte, 2001;Yang et al, 2010). Actually, few research work have focused on the biocontrol efficacy of Trichoderma spp against Verticillium in vivo though important antagonistic potential were involved against Verticillium dahliae when in vitro assays were applied.…”

In this study three Trichoderma species isolated from Moroccan soil (natural and agricultural habitats) were investigated for their biocontrol potential against virulent Verticillium dahliae on eggplant in green house conditions based on dipping root approach. Evaluation of biocontrol efficacy of Trichoderma spp. demonstrated effective potential of Trichoderma on reducing Verticilium disease on eggplant cultivars. Disease assessment was established by measuring disease incidence in root units (DI-RU) and in the above ground of eggplant cultivars (DI-AU). DI-RU% was recorded at 12.5%, 25.0%, 31.3% and 37.5% in T3, TC, T1 and T2 treatment respectively where DI-RU recorded in Tm2 controls; eggplants inoculated with Verticillium only was equal to 100.0%. Whereas, disease incidence outcomes in aerial part was DI-AU = 100.0% in treatments TC and T2, 87.5% in T1 and 96.0% in T3 treatment where Tm2 controls were assessed with 100.0%.
