Cotton (Gossypium hirsutum) is an important agronomic crop in the Southeastern United States. In 2018 cotton seed production in the United States was estimated at 5.11 million metric tons with an average yield of 1.24 metric tons per hectare (NASS-USDA, 2019). Reniform nematode (Rotylenchulus reniformis Linford and Oliveira, RN) is a significant pathogen of cotton that is typically managed by crop rotation or nematicide application (Linford and Oliveira, 1940; Moore and Lawrence, 2012

The first report on the bio-efficacy of AgNP on a plant-parasitic nematode was provided by Cromwell et al. (2014) against root-knot nematode on bermuda grass with mixed results, the lab assays revealed promising results but field experiments were not conclusive. Subsequent studies have explicitly revealed promising results of AgNP (Abdellatif et

Peanut producers rely on crop rotation, resistant cultivars, and nematicide application to manage PRKN. Peanut cultivars (TifNV High O/L, Georgia 14 N, and Tifguard) that are highly resistant to root-knot nematodes are available and derive resistance from the parental cultivar COAN (Holbrook et al., 2008; Branch et al., 2014; Holbrook et al., 2017). These resistant cultivars are not widely adopted as a majority of

Studying population changes of nematode functional groups can provide insight into potential effects of nematicides on soil health (Ferris et al., 2001). We conducted nematicide treatment programs in order to better understand potential non-target effects on non-herbivore free-living nematode community structure. We predicted nematicide applications would significantly affect nematode community structure by decreasing the number of nematodes belonging to high trophic levels

(2015) found a combination of the nematicide seed treatment Aeris® (thiodicarb) with two foliar applications of Vydate® C-LV (oxamyl) applied after germination and the 2 to 8 leaf stage reduced R. reniformis and M. incognita populations. Commercially available fertilizers can be applied as a broadcast, dribbled, knifed-in or banded during planting (Oldham, 2017

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

The metabolism assays indicated that ALA treatment significantly altered the nematode metabolism including the total protein production, malondialdehyde (MDA) content, and oxidase activities. This study suggested that ALA is a promising nematicide against plant-parasitic nematodes.

In 2012, theWashington raspberry (Rubus idaeus) industry received a special local needs (SLN) 24(c) label to apply Vydate L (active ingredient oxamyl) to nonbearing raspberry for the management of Pratylenchus penetrans. This is a new use pattern of this nematicide for raspberry growers; therefore, research was conducted to identify the optimum spring application timing of oxamyl for the suppression of P. penetrans. Three on-farm trials in each of 2012 and 2013 were established in Washington in

Despite the very significant yield losses caused by the nematode, no nematicide has been registered for the control of plant-parasitic nematodes on sugarcane in Japan. Though alternative approaches to control plant-parasitic nematodes in sugarcane fields are available, such as antagonistic plants and crop rotation, nematicides may be an effective tool for

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

Nematicides continue to be an important part of an integrated system to manage root-knot nematodes in cotton and soybean. 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

Specifically, the objectives were to (i) assess turfgrass chemical nematicides for their ability to impact visual quality ratings, NDVI, and NDRE values on M. incognita and B. longicaudatus infected bermudagrass in microplots, and (ii) to advance to a golf course infested with multiple genera of plant-parasitic nematodes and assess the chemical nematicides ability to influence these same vigor ratings.

Its biochemical mode of action is presently unknown but in laboratory studies it caused adverse effects at concentrations around 1 to 50 ppm (a.i.) on various fitness parameters (motility, mobility, and infectivity) of Meloidogyne incognita, M. javanica, and M. hapla (Thoden and Wiles, 2019; Thoden et al., 2019).

Overall, most entries of C. lanatus var. citroides performed similarly with and without nematicide treatment in regard to root galling, visible egg masses, vine vigor, and root mass. In both years of field evaluations, most C. lanatus var. citroides accessions showed lesser degrees

In conclusion, phenolic monoterpenoid eugenol could be useful as a potential plant-based nematicide with contact action to control M. javanica. However, further study is needed to develop formulation, concentration and application times to improve eugenol efficacy under field conditions for practical use as novel nematicide or hatching

Ditylenchus dipsaci motility was more tolerant to fluensulfone compared to Pratylenchus penetrans, P. thornei, and Aphelenchoides fragariae (Oka, 2014). Recovery in the motility of D. dipsaci was evaluated after 72 h because the majority of nematodes were still motile at 24 h for most of the fluopyram concentrations. There was no increase in motility in D. dipsaci after exposure to

The commercial nematicide fosthiazate acting on acetylcholinesterase was used as control.For this reason, scanning electron microscopy and transmission electron microscopy have been employed. The acetic acid mainly harmed the cuticle, degenerated the nuclei of pseudocoel cells, and vacuolised the cytoplasm. The (E)-2-decenal and 2-undecanone did neither harm to the cuticle nor the somatic muscles but they degenerated the

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

Because of the reliance on a small selection of older nematicides, the development of new tools for SRKN management is important. One group of new tools are the benzamide, non-fumigant nematicides, such as fluopyram.
