Sustainable Management of Citrus Nematodes: Exploring Bio-Friendly Control Strategies for Valencia Orange Trees

Main Findings: A research team examined the nematicidal effects of abamectin, boron, chitosan, hydrogen peroxide, and Bacillus thuringiensis on Tylenchulus semipenetrans in Valencia orange trees. The results demonstrated significant reductions in nematode populations and improved fruit yield and quality:

  • Nematode Reduction: The highest efficacy was observed with oxamyl, boron, abamectin, chitosan, and hydrogen peroxide, achieving nematode reductions between 70-83%.
  • Yield Improvement: Boron treatment led to the highest increase in fruit yield (83.2%), followed by oxamyl (70.3%).
  • Fruit Quality Enhancements: Boron and chitosan increased total soluble solids by 13.6% and 11.2%, respectively, while also boosting vitamin C content.

Broader Implications and External Insights: The American Phytopathological Society emphasizes the growing need for environmentally friendly pest management strategies in agriculture. Implementing bio-nematicides can reduce chemical pesticide dependency while maintaining citrus health and productivity.
