Greenhouse experiment demonstrates combined Arthrobotrys oligospora and salicylic acid suppress Meloidogyne incognita in tomato, indicating viable eco-friendly nematode biocontrol.

Key Points

To evaluate the individual and combined suppressive effects of Arthrobotrys oligospora and salicylic acid on Meloidogyne incognita infection and defense responses in tomato plants.
Conducted a greenhouse trial on Solanum lycopersicum infected with M. incognita treated with A. oligospora, salicylic acid, or a combination of both.
Measured plant growth, yield parameters, defense-related enzyme activity (PAL, POD, SOD, β-1,3-glucanase), stress markers (MDA, proline), and root histological alterations.
Combined treatment significantly (P < 0.05) elevated β-1,3-glucanase, PAL, POD, and SOD activities while significantly reducing proline and MDA concentrations compared to nematode-infected controls.
Combined application significantly reduced nematode disease index, reproduction factor, and root penetration, preserving vascular bundle integrity relative to single-treatment and infected controls.
