“…In the field trials, the most effective treatments for reducing M. hapla soil densities were 1,3-dichloropropene:chloropicrin, methyl iodide:chloropicrin, and dimethyl disulfure, whose efficacies ranged from 78% to 87%, which is in keeping with the perception farm advisors have about how efficient soil fumigants are, since they ranked 1,3-dichloropropene:chloropicrin as being the most efficient method, followed by dazomet and metam-sodium. The fumigant 1,3-dichloropropene:chloropicrin has proved to be effective in controlling root-knot nematode globally [16][17][18][19], and these field trials confirmed these results. When there is high nematode pressure, 1,3-dichloropropene:chloropicrin may be the best option for controlling nematodes adequately and reaching profitable yields, since even at Pi >100 J2 per 100 g of soil, soil fumigation with 1,3-dichloropropene:chloropicrin reduces soil nematode densities below the tolerance limit.…”

“…When there is high nematode pressure, 1,3-dichloropropene:chloropicrin may be the best option for controlling nematodes adequately and reaching profitable yields, since even at Pi >100 J2 per 100 g of soil, soil fumigation with 1,3-dichloropropene:chloropicrin reduces soil nematode densities below the tolerance limit. Soil fumigation with 1,3-dichloropropene:chloropicrin was more effective and consistent in suppressing B. longicaudatus populations in strawberry crops in Florida compared to other chemical nematicides, such as metam-sodium, dazomet, fluensulfone, fluazaindolizine, or fluopyram [19]. Furthermore, mixtures of 1,3-dichloropropene and chloropicrin work synergistically to control a wide range of plant pathogens and pests, which include fungi, nematodes, insects, mites, rodents, weeds, and some bacteria and have been recommended as being the best option for controlling soil borne pathogens in many intensive crops.…”

“…Non-fumigant soil disinfestation in strawberry production, such as steam, biofumigation, solarization, or soil-less cultivation, are not highly effective methods of reducing nematode soil populations or are uneconomical if used on their own [16][17][18][19][20]. However, combining biofumigation with organic manures plus soil solarization has proved to be an efficient way of controlling weeds and soil-borne diseases in strawberries, such as Rhizoctonia spp., Phytophthora cactorum, and Macrophomina phaseolina, in Turkey and Spain [20,59,60], and in our field trials, soil biosolarization reached efficacies of 73% reduction for M. hapla and 67% for P. penetrans, which seems to provide sufficient nematode control in most situations.…”

“…However, the use of most soil fumigants is forbidden or strictly restricted within the European Union (Directive 2009/128/CE) and elsewhere for environmental and safety reasons. Extensive research has been done on alternative chemical [17][18][19] and non-chemical methods [18][19][20] for controlling nematode diseases. However, the efficacy of these alternative methods in reducing soil nematode densities is lower than soil fumigation, and many have not proven consistency enough when used in intensive crop farming [17][18][19][20].…”

(1) Background: Spain is the sixth strawberry producer in the world, with about 6500 ha producing more than 350,000 tons, and an annual commercial value about 390 million €. Stunted and dead strawberry plants are frequently associated with plant-parasitic nematodes, but nematode diseases have not been characterized to date in the country. (2) Methods: A poll on the perception of the impact of nematodes on strawberry production was carried out by face-to-face interviews with farm advisors. In addition, nematological field surveys were carried out at the end of the growing season in 2017 and 2018 to determine prevalence and abundance of plant-parasitic nematodes in strawberry crops. The host suitability to Meloidogyne hapla of seventeen strawberry cultivars and the tolerance limit to M. hapla at progressively higher initial population densities (Pi) were assessed in pot experiments in a growth chamber. Comparison of the relative efficacies of several soil disinfestation methods in controlling nematode populations (M. hapla and Pratylenchus penetrans) was carried out in experimental field trials for twelve consecutive years. (3) Results: Meloidogyne spp., Pratylenchus penetrans, and Hemicycliophora spp. were the main plant-parasitic nematodes in the strawberry fields in South Spain. Root-knot nematodes were found in 90% of the fields, being M. hapla the most prevalent species (71% of the fields). A tolerance limit of 0.2 M. hapla juveniles per g of soil was estimated for strawberry, and currently cropped strawberry cultivars did not show resistance to M. hapla. Nematode population densities were reduced by more than 70% by soil fumigation with 1,3-dichloropropene, dazomet, dimethyl-disulfide, and methyl iodide. The efficacy of metam-sodium in reducing nematode populations was about 50% and that of chloropicrin, furfural, and sodium-azide, less than 40%. Combination of solarization with organic manures (biosolarization) reduced soil nematode populations by 68–73%. (4) Conclusions: Plant-parasitic nematodes (Meloidogyne, Pratylenchus, and Hemicycliophora) are widely distributed in the strawberry fields of Southern Spain. Strawberry is a poor host for M. hapla with a tolerance limit of 0.2 J2 per g of soil, and low population increases in cropping cycles of 7–8 months. Strawberry cultivars show a range of susceptibility and tolerance to M. hapla, but no resistance is found. Nematodes are effectively controlled by chemical fumigation of soils, but soil biosolarization is equally effective, and therefore, can be proposed as a sustainable alternative for pathogen control in strawberry cultivation.

“…This suggests that although nematode populations in the soil appear to have been suppressed in the chloropicrin treated soil at the time of planting, the fumigated soil was reinfested with M. javanica by the end of the growing season. Other studies have also documented rapid reinfestation of fumigated soil with plant‐parasitic nematodes, including on apple, sweet cherry, and strawberry, and this phenomenon is likely the result of elimination of microbial antagonists in soil responsible for natural pest regulation . This appears to have had negative implications on the double‐cropped cucumber plants, which displayed significantly more root galling in the soil fumigated with chloropicrin and chloropicrin +1,3‐dichloropropene.…”

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

BACKGROUND The nematicidal effects of fluopyram were evaluated for the suppression of Meloidogyne ethiopica and migratory nematodes, Xiphinema americanum s. l., Hemicycliophora spp. and Pratylenchus spp., in two commercial tomato greenhouses in Chile. The effects of fluopyram on plant‐parasitic nematodes, plant vigor and fruit yield were determined. RESULTS Fluopyram demonstrated good potential for the management of M. ethiopica and migratory nematodes, especially during the early stages of evaluation (30–60 days after planting). There were also improvements in vigor of treated plants. A general trend in improved fruit quality was also observed, however, no significant differences in total yield were found between treatments. CONCLUSIONS Our study is one of the first evaluations of fluopyram under field conditions against M. ethiopica. The findings suggest that this new nematicide has good potential for the management of M. ethiopica and some migratory nematodes in tomatoes cropped in greenhouses in the Metropolitan Region of Chile. © 2021 Society of Chemical Industry
