Effect of Seed Treatment with Pseudomonas Fluorescens Alone and In Combination with Soil Application of Carbofuran and Neem Seed Powder against Meloidogyne Incognita in Okra

Investigation was carried out to determine the effect of seed coating of okra cv. UV with Pseudomonas fluorescens alone and in combination with soil application of carbofuran @ 1 and 2 kg ai ha⁻¹ ann deem seed powder @ 1% (w/w) against Meloidogyne incognita. Root-knot nematode was inoculated in the rhizosphere on 15 day olo plpnts @ 2 J2 per cm³ soil. Nematode penetration and galling was reduced by 54 and 70%, respectively, on application of bacterium, carbofuran (1 kg ha⁻¹) and neem seed powder compared to control (nematode alone). The reproduction factor (RF) was minimum (0.4) and the shoot root ratio maximum (7.2) in the above treatment.
