  • Title: Influence of soil environments on nematicidal activity of fluensulfone against Meloidogyne javanica.
    Author: Oka Y, Shuker S, Tkachi N.
    Journal: Pest Manag Sci; 2013 Nov; 69(11):1225-34. PubMed ID: 23456999.
    Abstract:
    BACKGROUND: Fluensulfone, a fluoroalkenyl group nematicide, has proved to be very effective in controlling root-knot nematodes, Meloidogyne spp. The authors evaluated some soil environmental factors that might affect its nematicidal activity. RESULTS: Meloidogyne javanica juveniles exposed to fluensulfone lost their infectivity, even though they were rinsed in water when they were still active. Exposure of juveniles to fluensulfone at >1 mg L(-1) for 48 h was very effective in reducing root galls. Peat as organic matter added to soil reduced nematicidal efficacy against M. javanica in pot experiments. Peat added to a soil column inhibited the downward movement of fluensulfone. The movement of fluensulfone was faster in sandy vs loess soil. Repeated soil application of fluensulfone did not reduce the nematicidal activity of fenamiphos or cadusafos, and repeated applications of these nematicides did not lower the nematicidal activity of a subsequent application of fluensulfone. CONCLUSION: Fluensulfone nematicidal activity and movement were affected by organic matter and clay content, probably via adsorption. Enhanced biodegradation or cross-biodegradation of fluensulfone by other compounds was not observed. Soil environment should be considered to obtain effective nematode control efficacy with a given compound.
