“…Imicyafos, a new nematicide based on organophosphate, was released in Japan in 2010, nearly 20 years after the release of fosthiazate, which had been a well‐accepted nematicide in several countries because of its relatively high nematode control efficacy . Currently, the most widely used non‐fumigant nematicides are organophosphates or carbamates, such as ethoprophos, fenamiphos, fosthiazate and oxamyl …”

“…Meloidogyne javanica (Treub, 1885) Chitwood, 1949, M. incognita (Kofoid and White, 1919) Chitwood, 1949, M. arenaria (Neal, 1889) Chitwood, 1949and M. hapla Chitwood, 1949 are the most common species of root-knot nematodes, being responsible for at least 90% of all the plant damages caused by nematodes (Castagnone-Sereno, 2002). It was also found that the rootknot nematodes are the most predominant group that are targeted by 48% of the global nematicides used for all crops (Haydock et al, 2006).…”

The nematicidal potential of vermicompost (VC), vermicompost tea (VCT) and the bacterial bioagent Nemaless ® was evaluated against Meloidogyne incognita infecting banana (Musa acuminata) cv. "Grand Nain" as compared to the nematicide fenamiphos 40% EC under laboratory and field conditions. Experiments were carried-out during two successive seasons (2016 and 2017). Results of the laboratory tests showed that the toxicity of VCT and Nemaless ® to M. incognita second-stage juveniles (J 2 ) was increased as their concentrations and exposure times were increased. The LC 50 of VCT ranged from 30.86 × 10 3 to 83.77 × 10 5 mg/l, while the LC 50 of Nemaless ® ranged from 2.69 × 10 8 to 3.17 × 10 8 cell/ml. Results from the field experiments revealed that all of the tested treatments greatly suppressed (P ≤ 0.05) the numbers of galls, egg-masses and nematode final populations. The most potent materials in reducing the numbers of M. incognita in banana soil, in a descending order, were: fenamiphos, Nemaless ® , vermicompost and vermicompost tea (VCT).

“…However, the number of commercially available chemical nematicides has declined in recent years due to their inherent toxicity and potential to cause environmental damage. Since the late 1970s, bans and restrictions for a majority of nematicides have left an urgent need for new nematode management solutions (Hague & Gowen, 1987;Haydock et al, 2013).…”

Spirotetramat (Movento™, Bayer CropScience) (SPT), an effective insecticide, has also demonstrated potential activity as a nematicide. No significant effects on hatching rates of Caenorhabditis elegans, Meloidogyne incognita or Heterodera glycines were observed when eggs were soaked in a maximum concentration of 105 ppm of technical grade spirotetramat-enol (SPT-enol), the active form in plants. Synchronised first-stage juveniles of C. elegans soaked in SPT-enol concentrations as low as 30 ppm demonstrated arrested juvenile development with calculated EC95 of 44-48 ppm. Single applications of formulated SPT (Movento 240SC) were applied to plant foliage at the labelled insecticidal rate of 87.6 g a.s. ha−1 at 1-week intervals on soybean plants inoculated with H. glycines or tomato plants inoculated with M. incognita in glasshouse tests. SPT consistently inhibited nematode development to reproductive maturity when applied at 1-2 weeks after inoculation. Optimal SPT application timings coincide with early stages of root infection, when nematodes are still in vulnerable juvenile stages.
