Systemic nematicidal activity of fluensulfone against the root‐knot nematode Meloidogyne incognita on pepper

Abstract

Fluensulfone showed relatively high nematode control activity when sprayed on the foliage before inoculation. Fluensulfone may be used as a foliar application, in addition to soil application, for root-knot nematode control.

Systemic nematicidal activity and biocontrol efficacy of Bacillus firmus against the root-knot nematode Meloidogyne incognita

“…Four replicates were set form each treatment. The following data were collected 40 days after the first drenching application: the galling index of root was assessed on a scale of 0-5 (Oka et al 2012); nematode egg masses were extracted from infested root of each plant by shaking root in 1 % NaClO (Hussey and Barker 1973), and counted; 200 g rhizospheric soil per plant was collected to determine the final population of nematode in soil based on the centrifugalflotation technique (Jenkins 1964). The shoot height, the root length and weight per seedling were recorded.…”

Anthelmintic drugs and nematicides: studies in Caenorhabditis elegans

“…Fluensulfone (5-chloro-2-(3,4,4-trifluorobut-3-enylsulfonyl)-1,3-thiazole) is a member of the fluoroalkenyl thioether group and has proven potential as a new nematicide to control plant parasitic nematode infections (Oka et al, 2012;Oka et al, 2009). For example, application of fluensulfone through both soil drenching and foliar spray has been shown to significantly reduce root infection and penetration by plant parasitic nematodes, Meloidogyne javanica (Oka et al, 2009) and M. incognita (Oka et al, 2012).…”

Fluensulfone has marked effects on the development and behaviour of C. elegans and the profile of its effects is different from the other main classes of anthelmintic and nematicides including levamisole, ivermectin, and the organophosphates, suggesting a distinct mode of action (Kearn et al, 2014).…”

Isolation and characterisation of rhizosphere bacteria active against Meloidogyne incognita , Phytophthora nicotianae and the root knot-black shank complex in tobacco

“…The DS for P. nicotianae was rated on the following 0–5 scale: 0 = no visible disease symptoms; 1 = leaves slightly wilted, with brownish lesions beginning to appear on stems; 2 = 30–50% of plant foliage wilted; 3 = 50–70% of plant foliage wilted; 4 = 70–90% of plant foliage wilted; 5 = plant dead. The DS of M. incognita was assessed by rating the galling index of the roots on a scale of 0–5: 0 = no galled roots; 1 = 1–20% galled roots; 2 = 21–40% galled roots; 3 = 41–60% galled roots; 4 = 61–80% galled roots; 5 = 81–100% galled roots. A scale of 0–5 was proposed to evaluate the DS of the disease complex caused by P. nicotianae and M. incognita : 0 = no visible disease symptoms on the entire plant; 1 = leaves slightly wilted, with brownish lesions beginning to appear on the stems, 1–20% galled roots; 2 = 30–50% of entire plant was diseased, 21–40% galled roots; 3 = 50–70% of entire plant was diseased, 41–60% galled roots; 4 = 70–90% of entire plant was diseased, 61–80% galled roots; 5 = 81–100% galled roots, plant dead.…”
