The Relevance Of Poultry And Pig Droppings As Nematode Suppressants On Okra And Tomato In Ibadan, Southwestern Nigeria

Management of root knot nematodes (Meloidogyne spp.) on tomato (i>Lycopersicon lycopersicum ) using organic wastes in Zaria, Nigeria

“…by 24.4% to 87.9%. Beneficial effects of organic wastes on nematode control and crop growth were also observed by other researchers (Abubakar & Majeed 2000;Akhtaran & Abdul Malik 2000;Tijani et al 2000;Nwanguma & Awoderu 2002;Abubakar & Adamu 2004;Nico et al 2004).…”

“…Such materials include green manure, cow dung, poultry droppings, dried crop residues, botanicals, camel dung, and composted agro-industrial wastes. A remarkable reduction in nematode populations both in greenhouses and field conditions with an attendant increase in crop yield and growth has been achieved (Akhtar & Alam 1990, 1992Abubakar & Majeed 2000;Khan et al 2002;Nwanguma & Awoderu 2002;Abubakar & Adamu 2004;Nico et al 2004). RD, SD and RH are abundant in northern Nigeria and are often thrown away as wastes or burnt (as with RH and SD).…”

Efficacy of Organic Soil Amendments and a Nematicide for Management of Root-Knot Nematode <i>Meloidogyne</i> Spp. of Onion

“…by 24.4% to 87.9%. Beneficial effects of organic wastes on nematode control and crop growth were also observed by other researchers [32,[36][37][38][39][40]. Among all the treatments PR and Tricho-compost-2 recorded the highest improvement in plant growth and maximum reduction in the root knot disease severity.…”

Utilization of Organic Wastes for the Management of Phyto-Parasitic Nematodes in Developing Economies

“…on tomato in the villages of Arewaci and Kurmi Bomo of Zaria, Nigeria This is in conformity with the report of Miller et al, (1973) that availability of more nitrogen enhances the ability of the organic amendment to control nematodes. Similar achievements of nematode control through the use of several organic amendments have been reported by other workers (Abubakar and Adamu, 2004;Abubakar and Majeed, 2000;Khan and Shaukat 2002;Nwanguma and Awoderu, 2002;Nico et al, 2004). The abundance of refuse dump, industrial sawdust and rice husk all over Nigeria and most developing countries makes them very suitable candidates for deployment as soil organic amendments for the management of phyto-parasitic nematodes.…”

“…Since then several workers have reported that waste materials either of animal, plant or industrial origin have nematicidal and plant growth promoting properties (Akhtar and Alam, 1993;Chindo & Khan, 1990;Kimpinski et al, 2003. This has been exploited as an alternative means of nematode control (Abubakar and Adamu, 2004;Abubakar and Majeed, 2000;Hassan et al, 2010;Nico et al, 2004;Nwanguma and Awoderu, 2002;). The beneficial effects of organic incorporation have been generally considered to be due to increase in soil nutrients, improvement in soil physical and chemical properties (Huang and Huang, 1993;Hungalle, et al, 1986;Kang et al, 1981), direct or indirect stimulation of predators and parasites of phyto-parasitic nematodes (Kumar, 2007;Kumar et al, 2005;, and release of chemicals that act as nematicides (Akhtar and Alam, 1993;Sukul, 1992).…”
