With the cancellation of fenamiphos in the near future, alternative nematode management tactics for plant-parasitic nematodes (PPN) on golf courses need to be identified. The use of entomopathogenic nematodes (EPN) has been suggested as one possible alternative. This paper presents the results of 10 experiments evaluating the efficacy of EPN at managing PPN on turfgrasses and improving turf performance. These experiments were conducted at various locations throughout Florida over the course of a decade. In different experiments, different EPN species were tested against different species of PPN. Separate experiments evaluated multiple rates and applications of EPN, compared different EPN species, and compared single EPN species against multiple species of PPN. In a few trials, EPN were associated with reductions in certain plant-parasite species, but in other trials were associated with increases. In most trials, EPN had no effect on plant parasites. Because EPN were so inconsistent in their results, we conclude that EPN are not acceptable alternatives to fenamiphos by most turf managers in Florida at this time.
随着克线磷在不久的将来被禁用，需要确定高尔夫球场上用于防治植物寄生线虫（PPN）的替代线虫管理策略。有人建议使用昆虫病原线虫（EPN）作为一种可能的替代方法。本文介绍了10项实验的结果，这些实验评估了EPN在防治草坪草上的PPN以及改善草坪性能方面的效果。这些实验在佛罗里达州各地进行，历时十年。在不同的实验中，针对不同种类的PPN测试了不同种类的EPN。单独的实验评估了EPN的多种用量和施用方式，比较了不同种类的EPN，并比较了单一EPN种类对多种PPN的防治效果。在一些试验中，EPN与某些植物寄生线虫种类的减少有关，但在其他试验中则与增加有关。在大多数试验中，EPN对植物寄生线虫没有影响。由于EPN的实验结果如此不稳定，我们得出结论，目前在佛罗里达州，大多数草坪管理者认为EPN不是克线磷可接受的替代品。
