New reduced-risk agricultural nematicides - rationale and review

Nematicides can be credited for having put the science of nematology firmly on the map. The enormous amount of crop damage and yield loss that plant-parasitic nematodes can cause was not known until the first trials with nematicides in the 1920s (Taylor, 2003). From the 1950s to the 1970s, the discipline of nematology was booming and research on nematode biology, physiology, and management was rapidly expanding. This optimism started changing in the 1960s and 1970s, when some of the less

The impact of chemical nematicides on entomopathogenic nematode survival and infectivity

damaging high valued crop plants. Among these, however, chemical control is the most frequently and readily used approach. It involves the application of non-volatile, highly toxic and broad spectrum chemical nematicides such as fosthiazate, fenamiphos, ethoprophos, metam potassium, etc., to soil through drip irrigation or soil drenching. These chemicals are less toxic to handlers and operators than fumigant nematicides (Chitwood, 2003). Use of these nematicides to manage PPNs ensures that plant root

Nematicide effects on non-target nematodes in bermudagrass

typically have low thresholds for damage. Chemical nematicides are valuable for managing injurious nematode populations, particularly on golf courses (Crow et al., 2003). Nematicides have been shown to reduce plant-parasitic nematodes, but few studies have evaluated the effect on non-parasitic nematodes. These include bacterial-feeding (bacterivores), fungal-feeding (fungivores), omnivorous (omnivores), and predaceous (predatory) nematodes. Because of the high abundance, ubiquitous nature, and occupancy

) nematodes. On vegetable and tomato crops, nematode infestations result in stunting and poor yields. In a nematode-infested sweet potato field, poor plant growth and the deformity of the tubers are common. Environmental conditions in Hawaii are conducive for year-round nematode growth and reproduction. With limited post-plant nematode management options for disrupting the nematode life cycle, the application of chemical or biological nematicides through chemigation is often needed.

Nematicide efficacy at managing Meloidogyne arenaria and non-target effects on free-living nematodes in peanut production

results in that system (Kandel et al., 2017; Beeman et al., 2019). Research is needed to evaluate fluopyram efficacy for managing PRKN in peanut production, particularly given the limited number of nematicides available for peanut production. Increasingly, effect of pesticides on non-target organisms is an important consideration. In particular, free-living nematodes are a major non-target group of concern when nematicides are applied because they are biologically very similar to the target plant

Trenholm et al. (2005) also reported significant improvement in NDVI by nematicides on turfgrass infested with B. longicaudatus in greenhouse evaluations. Thus, this is a proven vegetative index for rating bermudagrass in conjunction with visual ratings. Another vegetation index used

Compatibility of fluazaindolizine and oxamyl with Pasteuria penetrans on spore attachment to juveniles of Meloidogyne javanica and M. incognita

to enter the root. When a J2 with attached spores invades the root and starts feeding, the spores germinate and proliferate inside its body. The parasite is highly selective within the nematode causing minimum disturbance to the physiological functions of feeding, molting, and growth while selectively destroying the reproductive capacity. Finally, the adult female does not lay eggs but instead becomes filled with spores of the parasite (Chen and Dickson, 1998). Modern nematicides should be

Effect of spirotetramat and fluensulfone on population densities of Mesocriconema xenoplax and Meloidogyne incognita on peach

when fluensulfone was applied through the drip. Since both spirotetramat and fluensulfone nematicides have shown detrimental effects on plant-parasitic nematodes of different crops, we hypothesized that the applications of these nematicides as post-plant treatments would be effective in controlling nematodes on peach. Therefore, the first objective of this research was to study the effect of both spirotetramat and fluensulfone on the mobility of M. incognita and M. xenoplax in an in vitro assay

Nematicidal Effects of 5-Aminolevulinic Acid on Plant-Parasitic Nematodes

Plant-parasitic nematodes are important agricultural pests and often cause serious crop losses. Novel, environmental friendly nematicides are urgently needed because of the harmful effects of some existing nematicides on human health. 5-Aminolevulinic acid (ALA) was reported as a potential biodegradable herbicide, insecticide, or plant-growth promoting agent. Lack of information on ALA against plant-parasitic nematodes prompted this investigation to determine the effects of ALA on Meloidogyne

species M. incognita and M. javanica are two of the most economically damaging pests in glasshouse-grown chrysanthemums that are produced for the cut flower industry in the Netherlands (Amsing, 2003, 2004). To combat RKN, chemical nematicides such as oxamyl are used (Desaeger et al., 2004). More commonly, the glasshouse soil is steamed every 5–6 growing cycles (c. once per year). Steaming is capable of suppressing various other soil-bound diseases such as Pythium, Fusarium, Rhizoctonia, Verticillium

Management of Root-knot Nematode (Meloidogyne incognita) onPittosporum tobira Under Greenhouse, Field, and On-farm Conditions in Florida

Root-knot nematodes are important pests of cut foliage crops in Florida. Currently, effective nematicides for control of these nematodes on cut foliage crops are lacking. Hence, research was conducted at the University of Florida to identify pesticides or biopesticides that could be used to manage these nematodes. The research comprised on-farm, field, and greenhouse trials. Nematicide treatments evaluated include commercial formulations of spirotetramat, furfural, and Purpureocillium lilacinum

They are most often utilized when M. incognita-resistant cultivars or non-host crop options are lacking. The presence of multiple species of economically important nematodes in a field may also require the use of a nematicide to limit yield losses. Fumigant nematicides are highly effective, but may require

Silver nanoparticles as a potential nematicide against Meloidogyne graminicola

biocontrol agents of plant-parasitic nematodes are few and offer limited choice. Carbofuran has been used widely in the recent times, but is slated to be phased out in near future. Environmentally benign chemical nematicides do not exist. Summer solarization of nursery beds is very effective but it is beset with certain limitations, such as being less effective in non-tropical and high rainfall regions. Moreover, rice is cultivated in multiple seasons in many areas and solarization is not possible in

reductions in root biomass, water uptake, and nutrient absorption. With the high potential for significant damage to turf by plant-parasitic nematodes, timely management is extremely important, especially on highly maintained turfgrass. The primary strategy for nematode management is through a limited number of chemical nematicides. Since its registration in 1973, fenamiphos (Nemacur, Bayer CropScience, St. Louis, MO) has dominated the turfgrass industry as the most frequently used nematicide (Keigwin

Because of the limitations of other management strategies and the high pressure from nematodes, fumigant and non-fumigant nematicide application is an important component of nematode management in Florida potato production. The limited number of nematicides labeled and available for Florida potato production is also a challenge for nematode management. In recent years, growers have temporarily or permanently lost use of some nematicides, such as oxamyl and aldicarb, due to
