“…Recently many researchers were focusing on employing the antagonistic microorganisms and ecofriendly materials to control or suppress phytoparasitic nematodes, (Montasser et al, 2012;El-Nuby, 2014;Viggiano et al, 2015;Thakur &Walia, 2016 andEl-Qurashi et al, 2019). One of the environmentally safe chemicals is amino acids that used in general as growth improvers.…”

Three amino acids (AAs) viz. glycine, L-proline and L-tryptophan plus yeast fungus, Saccharomyces cerevisiae, were tested against root knot disease, RKD, caused by root-knot nematode, Meloidogyne incognita on tomato cv. Super Strain-B. All AAs and yeast showed significant reduction in the number of galls, developmental stages, egg masses and fecundity of the treated plants associated with corresponding positive response in plant growth characters. Tryptophan gave significantly higher response in reducing the final nematode population followed by L-proline and glycine at high concentrations compared with yeast and check plants. In most cases, the soil drench application was more effective than foliar spray in reducing nematode build-up. The inhibitory effect of all treatments on nematode reproduction was positively correlated with increasing the concentration used. Plant growth was also promoted by all treatments used. Generally, All AAs gave significant impact in suppressing the development of the nematode pathogen and sequentially reliving the disease severity. Results of this research offered environmentally safe approaches for combating rootknot disease. Further researches are needed to determine the proper doses, and concentrations of tested AAs and yeast under semi-field and field conditions. Investigations must include the impact on plant yield, before recommending them for managing root-knot disease or promoting plant growth on a wide scale.

“…The application of OD formulation resulted in decrease of 67.9% in egg masses and 57.5% reduction nematode population in the soil compared to the control group. The control of nematodes of vegetables at seedling stage in P. chlamydosporia applied through wettable powder formulation as watering to the seedlings of lettuce at the rate of 18 g/litre was resulted in maximum reduction in number of eggs about 43.5% compared to the soil application (21%) reported by (Viggiano et al, 2015).…”

Pochonia chlamydosporia, a nematophagous fungus is well-known for its biocontrol potential against plant-parasitic nematodes. This review paper documented colonization patterns of P. chlamydosporia in soil, roots, and the rhizosphere, highlighting the impact of various abiotic factors on its establishment. The biocontrol efficacy of P. chlamydosporia against nematodes, including Meloidogyne spp., Globodera spp., and Heterodera spp., is extensively discussed, covering its mode of action and application methods. Additionally, the review delves into the enzyme secretion, endophytic nature, and secondary metabolites produced by P. chlamydosporia, shedding light on their roles in nematode control and plant growth promotion. P. chlamydosporia application triggers the activation of plant defence mechanisms is also elucidated, emphasizing its potential to induce a robust defence response in host plants. Overall, this comprehensive review consolidates the current knowledge on P. chlamydosporia, offering valuable insights for researchers, practitioners, and policymakers involved in sustainable nematode management strategies.
