摘要

This study assessed the efficacy of various commercial biotic and non-biological products in managing citrus nematode, Tylenchulus semipenetrans under field conditions. Fourteen products (6 bioagents, 7 non-biological formulations, and chemical nematicide) were applied as soil drenches. The chemical nematicide, Perfect demonstrated the highest nematode suppression, reducing soil populations by 81.4% and 56.3% after one month and two months, respectively. Among biocontrol agents, Mycorrhiza® and Biofertile® were most effective, achieving up to 79.5% and 60.6% reduction after one month. Promising non-biological treatments, included Actosol® and Nematotop®, wihich provided sustained control with up to 63.1% and 57.4% reduction after two months. Principal Component Analysis (PCA) revealed a clear distinction between treatment types, with biotic agents like Mycorrhiza associated with strong initial suppression and non-biological treatments like Actosol linked to more persistent. Our findings highlight the complementary potential of these treatments, supporting the development of integrated pest management (IPM) programs to decrease T. semipenetrans populations and reduce dependency on chemical nematicides.
