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.

“…The seed yield per plant was increased by 5.34% over the recommended dose of NPK applied. Trichoderma longibrachiatum has a higher potential of parasitic and lethal effects against Heterodera avenae, but its effects on wheat are fairly high in promoting plant growth and nematode control [18]. One strain of Trichoderma increases the numbers of deep roots at as much as a meter below the soil surface [19].…”

This experiment was conducted to find out the effects of Trichoderma viride on growth and yield of wheat at Institute of Agriculture and Animal Science, Lamjung Campus, Sundarbazar, Lamjung during December 2016 -April 2017. The experiment consisted of seven treatments; (T1: Control; T2: Soil + NPK; T3: Soil inoculated Trichoderma; T4: Trichoderma + FYM; T5: Trichoderma + ½ NPK; T6: Trichoderma + NPK and T7 = Trichoderma + NPK + FYM) laid out in completely randomized design (CRD) with three replications. The results showed that Trichoderma viride increased the plant height (4.6%), root weight (1.5%), leaf length (0.3%), panicle weight (9.1%), number of grains (3.8%), grain yield (36.5%), biological yield (13.7%), and biomass yield (2.7%) over control; while root length (-17.4%), number of leaves (-8.4%), tiller number (-10.8%), panicle number (-6.7%), panicle length (-8.4%) highlighted the negative impact of T. viride on wheat plant. T. viride displayed antagonism with inorganic fertilizer. When T. viride and NPK were accompanied with farmyard manure, most of the growth and yield parameter showed the highest value. Though Trichoderma viride decreases several growth parameters, it still can be used as biofertilizer which increases the grain yield. Using T. viride with a full dose of NPK during sowing stage may not be efficient and economical in terms of productivity. Introducing farmyard manure to T. viride gives better yield than T. viride alone.

“…The unique sedentary life style of this group of PPN render them especially vulnerable of being colonised by their natural enemies (Lopez-Llorca et al 2008). Cyst nematodes are globally distributed and were the first group of PPN reported to be parasitised by fungi (Kühn 1877), which spurred investigations to find additional nematode-antagonistic fungi ever since [ (Tribe 1977) Khan et al 2006;Szabó et al 2012;Zhang et al 2014). In contrast, none of the second important group of nematode-antagonistic Ascomycota, the Orbiliomycetes (Baral et al 2017) has been reported to parasitise nematode cysts and eggs.…”

Monocillium gamsii sp. nov. and Monocillium bulbillosum: two nematode-associated fungi parasitising the eggs of Heterodera filipjevi

Monocillium gamsii sp. nov. (Ascomycota, Hypocreales, Niessliaceae) isolated from eggs of the cereal cyst nematode Heterodera filipjevi is described and illustrated based on morphological and molecular phylogenetic evidence. The new taxon discovered in wheat fields in Turkey destructively parasitises nematode eggs. The infected eggs were readily colonised by the fungus, which produced microsclerotia. The fungus could be grown on artificial media and the parasitism of M. gamsii towards H. filipjevi was reproducible in vitro. Hyphae penetrating the nematode eggs entirely colonised the embryo, developed into multicellular chlamydospore and dictyochlamydospore-like structures eventually forming microsclerotia. Molecular and morphological differences and similarities between M. gamsii and its phylogenetically related species are discussed. Monocillium bulbillosum was found to be closely related to the new species. The pathogenicity of M. bulbillosum against H. filipjevi was also assayed in vitro because of its sister group relationship to M. gamsii revealing that this species was also capable of colonising eggs of H. filipjevi.
