“…The application of 1.12 kg ha −1 fluazaindolizine to M. javanica-infested tomato fields reduced the galling index for up to 2 months after transplanting in one of two trials, but no difference was found in final nematode populations or total yields compared to the control in either trial [80]. Similar results of a slight reduction in tomato root galling were observed by application at 0.9 kg ha −1 fluazaindolizine to M. javanica-infested fields [110]. In strawberry fields, the application of fluazaindolizine at 1.12 kg ha −1 at transplanting, with or without additional application at 0.56 kg ha −1 30 days after transplanting, did not reduce the populations of Belonolaimus longicaudatus, M. hapla, or Pratylenchus penetrans during the experimental periods, nor did they increase the yield [102].…”

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.

“…The cassava wastewater has been studied for more than 30 years for possible applications in pest management (Pinto-Zevallos et al 2018), against insects, nematodes, and fungi (Table 1). The pest species that have been evaluated are Coceus hesperidum L., Meloidogyne spp., and Oidium sp., which are associated mainly with crops of fruit trees and tomato (Lebeda et al 2015;Abdul-Rassoul 2016;Regmi and Desaeger 2020).…”

Pests have a negative impact on the economy and the environment. There is an increased urgency for adequate pest control because many pests show high adaptation and climate change has created favorable circumstances for pests. For pest control, synthetic chemicals are used that are lethal to non-target organisms and are toxic to pollinators and aquatic invertebrates. Chemical compounds in plants and derivatives from lignocellulosic materials act against pests. The wastewater from lignocellulosic biomass is a potential source of new compounds with bactericidal, fungicidal, and pesticidal effects that have demonstrated inhibitory activity against plant pathogens. Fungicidal, nematicidal, insecticidal, larvicidal, and bactericidal activities have been proven. Inorganic and organic compounds, such as phenols, aldehydes, esters, and furanics, are the main ones identified. Due to the antimicrobial activity of wastewater, applying it to the soil can modify the composition and structure of key microbial communities. Deep research about richness, biodiversity, functionality, and microbials is needed. This review provides a comprehensive overview of wastewater types that have been applied and possible sources to obtain potential compounds for pest control. Moreover, associated active compounds, recovery techniques, and environmental impacts are reviewed.

“…The soil used in this experiment was characterized as Myakka fine sand (Sandy, Siliceous Hyperthermic Oxyaquic Alorthod, 96% sand, 3% silt and 1% clay with pH of 7.6 and 0.8% organic matter) collected at the Gulf Coast Research and Education Center research farm in Wimauma, FL, USA (27°45 0 23.9 00 N, 82°1 3 0 23.2 00 W). 15 The soil was pasteurized at 70°C for 12 h using SST-15 1/8 cubic yard 120v Soil Sterilizer (Pro-Grow Supply Corp, Brooksville, WI, USA). Two weeks after the pasteurization, 1000 mL soil was added to 10 x 10 cm plastic pots and kept in incubators at three different temperatures (5, 15 and 25°C) for 72 h. Meloidogyne javanica was cultured on tomato 'Rutgers' for two months in the greenhouse and eggs were extracted from the infected roots using the sodium hypochlorite method.…”

BACKGROUND: Biotic and abiotic factors such as microbes and soil temperature can affect nematicide efficacy. Two experiments were conducted to test the effect of three soil temperatures on the efficacy of nonfumigant nematicides (fluopyram, fluensulfone, oxamyl and fluazaindolizine) against Meloidogyne javanica in pasteurized and natural soil in planta. RESULTS:The results showed that all tested nematicides were more efficacious in pasteurized than in natural soil. Temperature affected the nematicides differently with no effect of soil temperature on oxamyl and fluazaindolizine, whereas fluopyram and fluensulfone had greater efficacy at higher soil temperatures.CONCLUSION: Temperature effects were noted for some but not all nonfumigant nematicides. Fluopyram and fluensulfone were less effective when applied in cold soil, whereas oxamyl and fluazaindolizine were not affected by soil temperature. Although all nematicides resulted in almost complete control of M. javanica in pasteurized soil, this was not the case in natural soil, and much more root damage and nematode reproduction was noted in the latter.
