“…Specifically, previous studies have reported that T. viride MTCC No. 167, T. asperellum T-12, and T. harzianum T-78 were potential biological agents against M. incognita [22][23][24][25]. Furthermore, a few other microorganisms such as S. rubrogriseus, B. subtilis, P. putida and P. fluorescens have been employed in controlling M. incognita [13,26].…”

Background Root-knot nematode is one of the most significant diseases of vegetable crops in the world. Biological control with microbial antagonists has been emerged as a promising and eco-friendly treatment to control pathogens. The aim of this study was to screen and identify novel biocontrol agents against root-knot nematode, Meloidogyne incognita. Results A total of 890 fungal isolates were obtained from rhizosphere soil of different crops and screened by nematicidal activity assays. Snef1910 strain showed high virulence against second stage juveniles (J2s) of M. incognita and identified as Trichoderma citrinoviride by morphology analysis and biomolecular assay. Furthermore, T. citrinoviride Snef1910 significantly inhibited egg hatching with the hatching inhibition percentages of 90.27, 77.50, and 67.06% at 48, 72, and 96 h after the treatment, respectively. The results of pot experiment showed that the metabolites of T. citrinoviride Snef1910 significantly decreased the number of root galls, J2s, and nematode egg masses and J2s population density in soil and significantly promoted the growth of tomato plants. In the field experiment, the biocontrol application showed that the control efficacy of T. citrinoviride Snef1910 against root-knot nematode was more than 50%. Meanwhile, T. citrinoviride Snef1910 increased the tomato plant biomass. Conclusions T. citrinoviride strain Snef1910 could be used as a potential biological control agent against root-knot nematode, M. incognita.

“…In the present assessment, both the species of Trichoderma caused reductions in root galling, egg masses, fecundity, and reproductive factor of M. javanica. Many earlier studies have shown good control of root-knot nematodes and many plants pathogenic fungi by different species of Trichoderma [65][66][67][68]. Trichoderma species being omnipresent dwell freely in all types of soils and are frequently found in root ecosystems of plants.…”

In South Asian countries, the lucrative production of peaches has been seriously threatened by an assortment of biotic stresses especially nematodes. This situation compromises the achievement of sustainable development goals (SDGs) related to food security and zero hunger. Recently under changing climate, root-knot nematodes of the genus Meloidogyne have emerged as the most damaging phytopathogenic nematodes, while the efficacy of chemical control has remained limited. Therefore, a study was executed to assess the efficacy of four biocontrol agents including Pochonia chlamydosporia, Purpureocillum lilacinum, Trichoderma harzianum, and T. viride (at concentrations of 2.5 × 103, 5 × 103, 7.5 × 103, and 1 × 104) along with nematicide Rugby and a control treatment against Meloidogyne javanica on peach. The response variables included nematode infestations in terms of number of galls, egg masses, and reproductive factors. P. lilacinus and T. harzianum (1 × 104 concentration) reduced the number of galls by 18% and 16%, respectively, than the control. All biocontrol agents exhibited their effectiveness by significantly reducing number of egg masses, eggs per egg mass, and reproductive factors, while these remained statistically at par to each other. The study proved that application of these biocontrol agents holds potential for controlling root-knot nematodes and might be developed as a potent strategy to replace or at least reduce the use of traditional chemicals for avoiding environmental pollution and contamination.

“…Trichoderma species are commonly found in root ecosystems, which develop symbiotic relationships with different kinds of crops, by colonizing root surfaces and enter the epidermis to enhancing root growth, increasing production and improved nutrients uptake (Kiriga et al, 2019). Trichoderma have provided excellent control method against root-knot nematodes in previous studies (Sonkar et al, 2018). Al-Hazmi and Javeed (2016) reported that T. harzianum and T. viride suppressed nematode multiplication and root galling and increased growth of tomato plants.…”

Root-knot nematodes are considered one of the severe plant pathogens that can be managed effectively with chemical nematicides in spite of their hazards to humans and the environment. Our work focus on the efficacy of Bacillus subtilis, Trichoderma spp. culture filtrates, the bioproduct Top perfect and the nematicide Vydate ® L 24% for controlling Meloidogyne incognita infecting pepper plants cv. Balady. Under laboratory and greenhouse conditions, treatments with 0.025 and 0.05 μl of Vydate ® L 24%/ml distilled water caused the highest reductions ranging from 83.9-99% in nematode egg-hatching and increased 2 nd stage juveniles' mortality; the number of root galls and egg masses, followed by treatments with the (100 μl/ ml, 10 ml/200 cc soil and 50 ml/ kg soil) of B. subtilis, Trichoderma culture filtrates, and the bioproduct Top perfect which showed 60.4-79.8 % inhibition. Meanwhile, treatments with the low doses (50 μl/ ml, 5 ml/200 cc soil and 25 ml/ kg soil) of B. subtilis, Trichoderma culture filtrates and the bioproduct, Top perfect resulted in 23.5-59.6 % inhibition in nematode parameters compared with the check treatment. In comparison to check treatment under greenhouse conditions application of Vydate ® L 24% showed a 60.2-77.8% increase in growth parameters of pepper plants, followed by both treatments with high and low doses of B. subtilis, Trichoderma culture filtrates, and the bioproduct Top perfect which showed 43.1-58.8% and 29.7-42.0% increase, respectively. Tested biocontrol agents could achieve various degrees of root-knot nematode control on pepper plants infected with M. incognita under laboratory and greenhouse conditions.
