Abstract
The influence of six essential oils i.e. garlic, sesame, neem, castor, chamomile, and linseed added to aseptic culture (MS medium) used for growth of tomato seedlings cv Strain-B before transplanting in pots with sterilized sandy loam soil on Meloidogyne incognita infection was studied under greenhouse conditions 30±5°C. Results indicated that all of the tested essential oils introduced into growth media protected and improved tomato plant growth of either the infected or uninfected with nematodes to a certain extent. Among all tested materials, castor oil gave the highest increment in fresh weight of the whole plant either infected or uninfected with values of 135.42% and 217.59%, respectively. The same trend was observed with castor oil in respect to increasing shoot dry weight of the healthy tomato plants (37.14%) whereas recorded the second to linseed oil treatment with the infected plants with values of 32.56% and 35.2%, respectively. Moreover, sesame oil application achieved the second values to castor oil treatment in increase percentage of both fresh weight of whole plant (132%) as well as shoot dry weight (29.24%), respectively. The highest reduction percentage in nematode population was obtained with castor oil treatment which amounted to 93.53% followed by linseed oil application with value of 92.71%. Among all tested essential oils, sesame oil significantly decreased number of galls on tomato roots with reduction percentage of 90%, followed by those treated with either chamomile or linseed oils with value of 87.5% each. M. incognita did not produce egg-masses on plants treated with all of the tested materials and considered as highly resistant due to egg-masses indices (zero each) whereas those received linseed oil as very resistant with egg-masses index value of 3 and reduction percentage value of 97.4%.
