Abstract: The southern root-knot nematode (Meloidogyne incognita) is one of the major problems affecting squash production in Florida and worldwide. Calcareous soils exist in south Florida, and squash in Miami-Dade County is grown in this type of soil. Environmentally friendly and low-toxic non-fumigant nematicides for managing M. incognita are urgently needed. Fluazaindolizine is a new compound that has been evaluated on vegetable crops and proven to be a highly effective non-fumigant nematicide. However, its efficacy against M. incognita in squash and its effect on squash fruit yield in calcareous soils are not documented. Field trials were conducted in 2019 and 2020 to evaluate the effect of fluazaindolizine on root galling and populations of M. incognita in the soil, plant vigor, and fruit yield of squash grown in calcareous soils in south Florida. In both field experiments, all treatments containing fluazaindolizine significantly (p

氟氮杂茚茚的评价，一种新的杀线虫剂，用于管理钙质土壤中南瓜中的南方根结线虫

摘要：南方根结线虫（Meloidogyne incognita）是影响佛罗里达州和全世界南瓜生产的主要问题之一。佛罗里达州南部存在钙质土壤，迈阿密戴德县的南瓜生长在这种土壤中。急需用于管理南方根结线虫的环保低毒非熏蒸杀线虫剂。Fluazaindolizine 是一种新化合物，已在蔬菜作物上进行了评估，并被证明是一种高效的非熏蒸杀线虫剂。然而，它对南瓜中南方根霉的功效及其对钙质土壤中南瓜果实产量的影响没有记录。2019 年和 2020 年进行了田间试验，以评估氟氮杂茚茚对土壤中南方根结线虫和南方根结线虫种群的影响、植物活力、佛罗里达州南部钙质土壤中种植的南瓜的果实产量。在两个田间试验中，所有处理均显着含有氟氮杂茚（p
