Abstract
The effects of water extracts of cattle, rabbit and pigeon manures and jatropha seed powder and the chemical nematicides Furadan 10G, Ragby 60% and Vydate L 24% on controlling Meloidogyneincognita were studied. In vitro, the tested organic matters and nematicides caused significant decrease of nematode activity after 4 and 7 days of exposure. Treatments with the tested nematicides caused 98.4-99.2% inhibition of egg-hatching. Treatment with water extract of pigeonmanure caused 50.6%, followed by water extracts of cattle and rabbit manures and jatropha seed powder which showed 32.4-34.8% inhibition of egg-hatching.The effect of the previous organic matters and chemical nematicides each alone or the combination between them on controlling M.incognita on tomato plants cv. Marmande was evaluated. Treatment with the tested nematicides Furadan10G, Ragby 60% and Vydate L 24% resulted in great reductions (93.3-99.1%) in root galls and nematode egg-masses. Treatment with pigeon manure gave 65.3 and 67.5 % reductions in root galls and nematode egg-masses, respectively. The application of cattle and rabbit manures and jatropha seed powder resulted in 15.3-32.2% reduction in root galls and nematode egg-masses. Treatments with pigeon, rabbit manures and jatropha seed powder resulted in a significant increase in fresh and dry weights of shoot and root systems compared to other treatments. Treatment with each of the tested organic matters plus any of the tested nematicides caused 78.9-99.3% reduction in root galls and nematode egg-masses and caused a significant increase in fresh and dry weights of shoot and root systems compared to control (nematode treatment).
