“…Fluensulfone did not change the diversity level of free-living nematode fauna and had a very low suppressive effect on free-living nematodes while controlling Meloidogyne spp. effectively [32]. In the same study, fosthiazate was found not to affect the free-living nematodes' density, but it did affect their diversity.…”

“…Unlike insecticides and fungicides, which have higher numbers of products, each used for relatively specific insects or fungal genera/species, only a few nematicides are registered, mainly for a few nematode groups that are of high economic importance. Free-living nematodes in the soil, including bacterial-feeding, fungal-feeding, omnivorous, and predatory nematodes, are generally more tolerant to nematicides [31,32]. This means that free-living nematodes, which play an important part in the mineral turnover and biological equilibrium of the soil ecosystem, may be less affected.…”

“…This means that free-living nematodes, which play an important part in the mineral turnover and biological equilibrium of the soil ecosystem, may be less affected. Soil fumigants, on the other hand, are less specific to nematode groups and can suppress both plant-parasitic and free-living nematode populations [32,33].…”

The phaseout of methyl bromide and the ban on, or withdrawal of, other toxic soil fumigants and non-fumigant nematicides belonging to the organophosphate and carbamate groups are leading to changes in nematode-control strategies. Sustainable nematode-control methods are available and preferred, but not always effective enough, especially for cash crops in intensive agriculture. A few non-fumigant nematicides, which have a relatively high control efficacy with a low toxicity to non-target organisms, have been released to the market or are in the process of being registered for use. Fluensulfone, fluopyram, and fluazaindolizine are the three main and most promising next-generation nematicides. In this paper, several aspects of these non-fumigant nematicides are reviewed, along with a brief history and problems of old-generation nematicides.

“…Species diversity, which is reflected by the Shannon and Simpson indices, can directly reflect the heterogeneity of a community based on the number of species present and their relative abundances [35]. Higher values of the Shannon index and lower values of the Simpson index indicate high diversity [36]. The species diversity analysis showed that the species diversity of the sample P. eryngiu-SMS-CB Table S2).…”

In this study, a novel chlorimuron-ethyl-degrading Pleurotus eryngiu-SMS-CB was successfully constructed for remediation of soil historically contaminated with chlorimuron-ethyl. The P. eryngiu-SMS-CB was prepared using efficient chlorimuron-ethyl-degrading cocultured bacteria, Rhodococcus sp. D310-1 and Enterobacter sp. D310-5, with spent mushroom substrate (SMS, a type of agricultural waste containing laccase) of Pleurotus eryngiu as a carrier. The chlorimuron-ethyl degradation efficiency in historically chlorimuron-ethyl-contaminated soil reached 93.1% at the end of 80 days of treatment with the P. eryngiu-SMS-CB. Although the P. eryngiu-SMS-CB altered the microbial community structure at the beginning of the 80 days, the bacterial population slowly recovered after 180 days; thus, the P. eryngiu-SMS-CB does not have an excessive effect on the long-term microbial community structure of the soil. Pot experiments indicated that contaminated soil remediation with P. eryngiu-SMS-CB reduced the toxic effects of chlorimuron-ethyl on wheat. This paper is the first to attempt to use chlorimuron-ethyl-degrading bacterial strains adhering to P. eryngiu-SMS to remediate historically chlorimuron-ethyl-contaminated soil, and the microbial community structure and P. eryngiu-SMS-CB activity in chlorimuron-ethyl-contaminated soil were traced in situ to evaluate the long-term effects of this remediation.

The evaluation of nematicidal activity of the non- fumigant nematicide (fluensulfone) was evaluated for the control of the root-knot nematode Meloidogyne incognita in bell pepper crop (Capsicum annuum L.) under field conditions. The experiment was set up under a randomized complete block design with four replications. Six treatments were assessed for control of M. incognita: four doses of fluensulfone, one of the nematicide oxamyl and a control without application of nematicides. Ten days before transplanting, nematicides were applied in a single application via irrigation systems. The lowest final population densities of M. incognita in bell pepper crop were recorded in plots treated with fluensulfone at the dose of 2.75 L.ha-1, with an average of 25 juveniles. The higher percentage of efficacy was obtained with the application of fluensulfone at a dose of 2.75 L.ha-1. Fluensulfone showed a more efficient nematicidal activity as compared with oxamyl, which is the most used nematicide in horticultural crops in Mexico. Our results indicated that fluensulfone can be used as an alternative nematicide for the control of M. incognita in horticultural crops.
