“…In experiment 1, all chemical nematicides reduced root galling on tomato, whereas in experiment 2, only fluensulfone showed a trend towards nematode suppression. Although studies have shown that differences in the soil environment, such as organic matter and clay content, can alter nematicidal activity of some 3‐F nematicides, this would not account for the inconsistencies observed in this study. Other factors between growing seasons, such as precipitation, soil temperature, cultivar, and microbial activity may have played a more prominent role in contributing to the differences in nematicide performance.…”

BACKGROUND Two field experiments were conducted to determine the efficacy and field performance of three new non‐fumigant chemical nematicides (fluensulfone, fluopyram, and fluazaindolizine) and two biological nematicides (Burkholderia rinojensis strain A396 and Purpureocillium lilacinus strain 251) for management of root‐knot nematodes (Meloidogyne javanica) on tomato and associated double‐crops in Florida. RESULTS In experiment 1, soil fumigation with metam potassium increased plant growth and reduced root galling on tomato by 77% relative to that of the untreated soil. All non‐fumigant chemical nematicides reduced root galling on tomato (47–85% reduction); however, only fluensulfone showed a trend towards yield enhancement. In experiment 2, soil fumigation with chloropicrin increased plant growth and reduced root galling on tomato by 35% relative to that of the untreated soil; however, end‐of‐season populations of M. javanica in soil were larger than that of the non‐fumigated soil. Fluensulfone showed a trend towards reduced root galling and enhanced fruit yield, whereas other non‐fumigant nematicides did not. Double‐cropped cucumber was 69% more galled when planted into soil previously fumigated with chloropicrin relative to that of untreated soil, and also showed reduced plant vigor and fruit yield. CONCLUSION Fluensulfone shows significant potential to be a component of an integrated pest management strategy for tomato in Florida. © 2019 Society of Chemical Industry

“…pallida , at least during the first 44 DAP, and that population development can also be suppressed. Previous in vitro experiments have indicated that fluensulfone can inhibit nematode hatching and movement. Reducing the size of potential inoculum with respect to the number of J2 that infect a host crop is one, if not the main, principle underlying soil treatments with nematicides, the rationale being the direct relationship between the infection activities of the J2 and crop yield loss .…”

BACKGROUNDThree field experiments evaluated the performance of the nematicide fluensulfone against the potato cyst nematode Globodera pallida in Shropshire, England.RESULTSExperiments 1 and 2 showed reduced root infection and lowered multiplication of G. pallida following fluensulfone (Nimitz 15G ®) soil treatments at five rates (1.95, 3.00, 4.05 (full rate), 5.05 and 6.00 kg AI ha−1) and Nimitz 480EC ® at the full rate. Experiment 3 demonstrated a positive interaction between the full rate of Nimitz 15G and the potato variety Santé in the reduction of G. pallida. The fluensulfone treatments at the full rate had more consistent effects than the lower rates, and there were no greater effects for the treatments higher than this full rate. Generally, fluensulfone was less efficacious than oxamyl or fosthiazate, which suggests that the treatment may not be reliably integrated within shorter potato rotations.CONCLUSIONThe data suggest that fluensulfone soil application could make a useful addition to the few available nematicide treatments for the control of G. pallida rather than be a substitute for these treatments.© 2016 The Authors.

“…Wheeler et al (2013) observed the relationship between the irrigation rate, soil moisture and the nematicide performance. The studies of Oka et al (2013) indicated an impact of such soil environments as soil type and organic matter. It is possible that in favorable conditions, the efficacy may increase; however, it requires further detailed studies.…”

In 2013 and 2014, the effects of different products and plant extracts in the control of Aphelenchoides ritzemabosi (Schwartz, 1911) Steiner and Buhrer, 1932 on Anemone hupehensis plants variety Prinz Heinrich were estimated. Experiments were carried out under containerized cultivation. Evaluation of the effectiveness of nematicides was conducted using two common methods based on the number of nematodes per leaf and the percentage of damaged leaves. In both experiments oxamyl and abamectin, with aqueous extract of Allium sativum, were the most effective (efficacy about 40%). The aqueous bulb extracts of A. sativum, solution of extracts of Quillaja saponaria and solution of spirotetramat in combination with aqueous extract of A. sativum were ineffective. In both experimental years, the significant correlation between the number of nematodes in leaves and the sampling date was recorded. Based on Spearman rank correlation test and regression, it was shown that counting of nematodes in leaves is still the most reliable method for diagnosis of the damage caused by foliar nematodes.
