“…Fluazaindolizine is another novel fluorine compound with nematicidal activity. It acts by contact and affects muscle function that causes ceasing of feeding, paralysis and eventually mortality (Chen et al, ). In aqueous assays, juveniles of the second stage of the M. incognita exposed to fluazaindolizine exhibited increased immobility and death between 24–96 hr (Lahm et al, ).…”

New non-fumigant nematicides (fluensulfone, fluopyram and fluazaindolizine) were tested in greenhouse tomato trials aiming to evaluate its efficacy on the control of Meloidogyne incognita soil and root populations and plant produtivity. Plants of the cultivar Red Gnome were transplanted into 2,500 cm 3 fibre pots inoculated with 200 eggs of M. incognita/100 cm 3 of soil and treated with fluensulfone, fluopyram and fluazaindolizine, in two rates each. After eight weeks of incubation the plants were evaluated for fresh root and shoot weight, weight and number of fruits, egg mass number, population density and nematode reproduction factor. All nematicide treatments reduced the root gall index, the number of M. incognita egg masses, eggs/g root and the nematode reproduction factor when compared to the non-treated control.

“…The life cycle of Drosophila melanogaster was not affected after feeding with a diet containing 200 ppm fluazaindolizine. The DT 50 of the compound in the soil is strongly affected by the soil type and environmental conditions, but it reaches approximately 35 days in the root zone [16,17]. The fate of fluazaindolizine applied to a tomato field was studied, and metabolites in the soil and plants were analyzed, and it was found that fluazaindolizine was an easy degradable-nematicide [17].…”

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.

“…Artificial planting has become an inevitable trend due to the large demand and the lack of wild wolfberry resources. Consequently, the issue of pesticide residues which are inevitably caused by the extensive use of pesticides in plant cultivation [11], has attracted wide attention of the international community [12,13,14]. Organophosphorus and pyrethroid pesticides are frequently applied to improve the quality and yield during the course of the growth of wolfberry.…”

A multi-residue method for the determination of 107 pesticide residues in wolfberry has been developed and validated. Similar pretreatment approaches were compared, and the linearity, matrix effect, analysis limits, precision, stability and accuracy were validated, which verifies the satisfactory performance of this new method. The LODs and LOQs were in the range of 0.14–1.91 µg/kg and 0.46–6.37 µg/kg, respectively. The recovery of analytes at three fortification levels (10 µg/kg, 50 µg/kg, 100 µg/kg) ranged from 63.3–123.0%, 72.0–118.6% and 67.0–118.3%, respectively, with relative standard deviations (RSDs) below 15.0%. The proposed method was applied to the analysis of fifty wolfberry samples collected from supermarkets, pharmacies and farmers’ markets in different cities of Shandong Province. One hundred percent of the samples analyzed included at least one pesticide, and a total of 26 pesticide residues was detected in fifty samples, which mainly were insecticides and bactericide. Several pesticides with higher detection rates were 96% for acetamiprid, 82% for imidacloprid, 54% for thiophanate-methyl, 50% for blasticidin-S, 42% for carbendazim, 42% for tebuconazole and 36% for difenoconazole in wolfberry samples. This study proved the adaptability of the developed method to the detection of multiple pesticide residues in wolfberry and provided basis for the research on the risks to wolfberry health.
