Comparative efficacy of bioagents as seed treatment for management of Meloidogyne incognita infecting okra
AbstractA pot experiment was undertaken to evaluate different fungal and bacterial antagonists as seed coating treatments against the root-knot nematode, Meloidogyne incognita, infecting okra. The seeds of okra cv. A-4 were treated with Trichoderma harzianum, Trichoderma viride, Pochonia chlamydosporia, Paecilomyces lilacinus and Pseudomonas fluorescens at 20 g/kg seed. Carbosulfan 25 (DS) at 3% (w/w) was used as a treated control. The treated seeds were sown in soil infested with two second stage juveniles of root-knot nematode/g soil. Sixty days after sowing, the growth of okra plants was greater and the root-knot nematode population was reduced in all treatments compared to the untreated control.
