Stimulation of Nematode-Destroying Fungi by Organic Amendments Applied in Management of Plant Parasitic Nematode

Management of root-knot nematode Meloidogyne incognita (Kofoid and White) Chitwood in Tomato (Lycopersicon esculentum Mill. through poultry manure and rapeseed cake

“…The variation in flowering and maturity date revealed that application of poultry manure had an influence on the plant growth and development. This finding is in agreement with that of Wachira et al (2009) who reported that tomato flowering was earliest and more pronounced in plants grown in soil amended with optimum poultry manure. The finding of the authors is consistent with the one found in this experiment at the higher levels of poultry manure application except at the highest (20 ton/ha) level of the treatment.…”

“…Cruciferous residues as soil amendments are effective in reducing the population densities of many soil-borne plant pathogens (Ritu and Lodha, 2002). Studies in Nigeria, South East Asia and many other developing countries indicated that poultry manure, cruciferous residues and other organic west soil amendment increased the yield of tomato and suppressed root-knot nematode (Riegel and Noe, 2000;Orisajo et al, 2008;Pakeerathan et al, 2009;Ogulumba et al, 2010;Wachira et al, 2009). Rahman et al (2002) also reported that application of poultry manure at 3 ton/ha with mustard cake at 300 kg/ha significantly reduced root knot-nematode population and increased yield of tomato.…”

How Durable is Root Knot Nematode Resistance in Tomato?

“…It could be affected nematode motility at least partially with mycorrhizal root exudates. Although other strategies exist to control the RKN, including crop rotation, cultural manipulations (Goswami et al 2008), organic amendments (Wachira et al 2009), use of neem formulation (Javed et al 2008) and resistance rootstock (Jacquet et al 2005) but breeding for resistant cultivars have been popular since 1948, because of the simplicity of transferring single dominant R gene into elite cultivars. Now-a-days, it is a great challenge for breeders to bred crops against available isolates of RKN, which are evolved frequently.…”

Efecto nematicida de extractos de Quassia amara y Brugmansia suaveolens sobre Meloidogyne sp. asociado al tomate en Nicaragua.

“…En Nicaragua los nematodos fitoparásitos se combaten casi exclusivamente con nematicidas sintéticos, los cuales a pesar de ser efectivos y de rápida acción tienen las desventajas de contaminar fuentes de agua, ser altamente costosos y riesgosos para la salud humana (Wachira et al, 2009). Esto indica la importancia de la investigación en nematicidas botánicos, especialmente en la agricultura orgánica.…”
