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.
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.
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.
氟吡菌酰胺对智利两个商业化番茄温室中的密绕实蝇和迁移性线虫（包括美国滑刃线虫、半闭螺旋线虫和滑刃属线虫）的抑制作用进行了评估。测定了氟吡菌酰胺对植物寄生线虫、植物活力和果实产量的影响。
氟吡菌酰胺对密绕实蝇和迁移性线虫具有良好的防治潜力，特别是在评估的早期阶段（种植后 30-60 天）。处理过的植物活力也有所提高。同时也观察到果实品质的普遍改善，但处理之间的总产量没有显著差异。
本研究是首次在田间条件下对氟吡菌酰胺防治密绕实蝇进行的评估之一。研究结果表明，这种新型杀线虫剂对智利首都大区温室番茄中的密绕实蝇和一些迁移性线虫具有良好的防治潜力。 © 2021 英国化学学会。
