On-Farm Evaluation of Fluazaindolizine for Nematode Management in Okra in South Florida, 2024

Among the nematodes that damage vegetable crops, root-knot nematodes ( Meloidogyne spp.) and reniform nematodes ( Rotylenchulus reniformis) are the most widespread and economically significant. Root-knot nematodes are sedentary endoparasites inducing galls that disrupt water and nutrient uptake, while reniform nematodes establish feeding sites within root tissue, impairing plant vigor. This report evaluates the efficacy of a relatively new nematicide, fluazaindolizine, for managing these nematode populations in ‘Clemson Spineless’ okra ( Abelmoschus esculentus L.) in a vegetable grower field in Homestead, South Florida. The trial was conducted from May to August 2024. Results indicate no significant reduction in nematode populations in treated versus untreated plots, highlighting the complexity of fluazaindolizine efficacy in nematode management under specific soil and environmental conditions.
