| Abstract | ||||
| The efficacy of three nematicides i.e. carbofuran,fenamiphos and oxmayl and three soil types i.e.clay, clay loam and sandy for controlling , Meloidogyne incognita infected tomato plants cv.super strain B was evaluated under greenhouse conditions30±5oC. Results revealded that regardless of the tested soil types , all tested nematicides at any dose added greatly reduced the nematode penetration, number of galls per root system number of eggs per eggmass, nematode final population and nematode reproduction. Significant differences in such nematode criteria were recorded between all tested treatments and the untreated one. However, such nematode values greatly decreased by increasing the dose of nematicides application in the three soil types . Oxamyl ranked first in reducing such nematode criteria followed by fenamiphos and carbofuran in the sandy soil, whereas, in the clayloam soil, fenamiphos gave better result in reducing nematode criteria values followed by oxamyl and carbofuran at three doses of application .Moreover, in clay soil, oxamyl at all doses gave the highst effect in nematode parametes followed by fenamiphos and carbofuran at the dose 300 mg/kg soil. Results also, clearly indicated that the nematicidal efficiency of the tested compounds greatly varied according to the tested nematicide compounds and soil types. Carbofuran showed the lowest effect on such nematode values in clay, clay loam and sandy soils, respectively . Moreover an obvious improvement in tomato growth parameters was observed in all tested nematicides as compared with untreated soil. The highest percentage increase was obtained in plant grown in clay soil as compared with other tested soil types. | ||||
