Control of Meloidogyne incognita (kofoid and white) chitwood (root-knot nematode) of Lycopersicon esculentus (tomato) using cowdung and urine

Abstract

Screenhouse experiments were conducted to test the efficacy of cowdung and urine separately and in combination in the control of root-knot nematode of tomato. Equal quantities of cowdung, urine and their mixture were separately made up to one litre with autoclaved soil. Two weeks old seedlings of tomato raised in autoclaved soil were transplanted into soil manure mixture and inoculated with 1,000 second stage larvae of Meloidogyne incognita race I. Treatments were completely randomized and effects assessed based on plant height, dry weight, extent of galling and the nematode multiplication factor. Results obtained showed that cowdung, urine, and their mixture produced significantly higher result than the untreated control. Similarly, the mixture of urine and cowdung, produced significantly higher results than the separate treatments.

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).…”

Evaluation of Some Botanicals and Trichoderma harzianum for the Management of Tomato Root-knot Nematode (Meloidogyne incognita (Kofoid and White) Chit Wood)

“…The addition of botanicals to soil leads to a better environment for the growth of the roots. This enhances the utilization of soil nutrients, as a consequence of which the nematode damage might have been markedly reduced [64]. These botanicals may be act as substrate for the growth and multiplication of T. harzianum.…”

Study on approaches to integrated control of <i>Meloidogyne graminicola</i> in rice

“…Such increase in growth have been attributed to either improvement in soil condition resulting in greater root growth, thereby enhancing the utilization of soil nutrients or to changes in the biotic and abiotic environment of plants. These ultimately alter the host parasite relationship thereby minimizing the nematode damage (Abubakar et al, 2004).…”
