“…In the present investigation, the culture filtrates of P. lilacinum showed more nematicidal activity than P. chlamydosporia. Similar type of observations were recorded byHallman and Sikora, 1996, Kerry, 2000and Annapurna et al, 2018 who reported that P. lilacinum showed more egg hatch inhibition and juvenile mortality of M. incognita under invitro conditions. However, among the tested antagonists, P. fluorescens showed more juvenile mortality and egg hatch inhibition of M. incognita in 25, 50,75 and 100 percent concentration of culture filtrate at 24, 48, 72 and 96 hrs of exposure time.…”

“…The microorganisms showed their antagonistic activity through the release of secondary metabolites in the surrounding environment towards pathogen and that reduced the viability of pathogen such as nematodes (Blaxster andRobertson, 1998 andSharon et al, 2001). In the management of the plant-parasitic nematode, the application of culture filtrates of antagonist is the best method (Annapurna et al, 2018) for biological control of nematode. The potential benefits and fit fall must be examined so that effective native antagonist (s) can be utilized.…”

An experiment was conducted to study the nematicidal toxicity of native antagonists against Meloidogyne incognita. For this the native antagonists viz., Pseudomonas fluorescens, Bacillus megaterium, Azotobacter sp., Rhizobium sp., Purpureocillium lilacinum and Pochonia chlamydosporia were screened against Meloidogyne incognita under in-vitro conditions. For this, four different concentrations of culture filtrates viz., 25, 50, 75 100 percent were tested against M. incognita through egg hatch inhibition and second-stage juvenile's mortality at 24, 48, 72 and 96 hrs of exposure time for each antagonist. The entire antagonists were also found to be effective in causing mortality of J 2 with varying degrees at different concentrations of culture filtrates and at different exposure time. The relationship among the antagonists, concentration and time showed that all the tested antagonists were able to cause significant mortality of M. incognita J 2 with increase in the concentrations of filtrates and time of exposure. The result of in-vitro test reveals that all the tested antagonists showed varied nature of egg hatch inhibition and juvenile mortality of M. incognita. However, among the tested antagonists P. fluorescens was found to be most effective in causing the highest egg hatch inhibition and J 2 mortality of M. incognita in 25, 50, 75 and 100 per cent concentration of culture filtrates at 24, 48, 72 and 96 hrs of exposure time. Further, probit analysis showed that culture filtrate of P. fluorescens exhibit either low LC 50 values or less LT 50 values against J 2 of M. incognita in 25, 50, 75 and 100 percent concentration of culture filtrates at 24, 48, 72 and 96 hrs of exposure time as compared to the others antagonists and found to be best native antagonists against M. incognita.

“…J2. [61][62][63] In a recent study, Benttoumi et al 64 isolated Trichoderma harzianum and Trichoderma afroharzianum from the cysts of G. rostochiensis and culture filtrates resulted in significantly higher mortality of M. incognita J2 under laboratory conditions. Abbasi et al 65 identified the isolates of T. atroviride and Fusarium oxysporum with higher chitinases producing activity and suggested their use in commercial formulations against PCNs.…”

Potato cyst nematodes (PCNs; Globodera spp.) are one of the most difficult pests of potato to manage worldwide. Indiscriminate use of pesticides and their hazardous effects discourage the use of many chemicals for the management of PCNs. As a result, biological control agents and trap crops have received more attention from growers as safer ways to manage PCNs. The biological control agents such as Pochonia chlamydosporia, Purpureocillium lilacinum, Trichoderma spp., Pseudomonas fluorescens, Bacillus spp., Pasteuria spp., and others are recognized as potential candidates for the management of PCNs. Moreover recently, the use of trap crop Solanum sisymbriifolium also showed promise by drastically reducing soil populations of PCNs. Integration of these management strategies along with other practices including identification, conservation, and multiplication of native antagonists, will facilitate efficient management of the PCNs in potato cropping system. Some of the promising research approaches that are being used against PCNs are addressed in this review. © 2022 Society of Chemical Industry.

An experiment was carried out on the mechanism of Lantana camara leaf extract in the management of Meloidogyne incognita on tomato. For this, leaf extract of L. camara (25gm/75ml w/v) were evaluated at 25, 50, 75 and 100 percent concentration through egg hatch inhibition and larval mortality test. Invitro efficacy test showed that maximum egg hatch inhibition and J2 mortality of M. incognita were recorded in the 100 percent concentration of L. camara leaf extract. A pot experiment study recorded maximum plant growth parameters were recorded in the 50 percent concentration whereas; minimum nematode multiplication was recorded in the 100 percent concentration of L. camara leaf extract after 35 and 45 days after inoculation. Further, biochemical analysis of tomato root revealed that maximum activity of the peroxodase, polypheno oxidase and total phenol content was recorded at 35 DAI while the same declined at 45 DAI.
