Assessment Of Phytonematode Diversity In Citrus Orchards Under Different Soil Types And Climatic Conditions

Abstract

Phytonematodes Are A Major Constraint To Citrus Production Globally, Impacting Tree Vitality And Fruit Yield. This Study, Conducted During The Period From December 2023 To December 2024, Evaluated The Diversity And Distribution Of Plant-parasitic Nematodes In Citrus Orchards Across Varying Soil Textures (sandy, Loamy, Clayey) And Climatic Zones (tropical, Subtropical, Semi-arid). Soil And Root Samples Were Collected And Analyzed Using Standard Nematode Extraction And Morphological Identification Techniques. The Dominant Genera Identified Were Tylenchulus Semipenetrans, Meloidogyne Spp., And Pratylenchus Spp. Nematode Population Densities Were Significantly Influenced By Soil Texture, Moisture, And Temperature, With Sandy Soils And Warmer Climates Exhibiting Higher Diversity And Abundance. The Study Underscores The Role Of Soil–climate Interactions In Nematode Ecology And Advocates For Site-specific, Integrated Nematode Management Strategies To Enhance Sustainable Citrus Production.
