| Abstract |
Five treatments (suspension Bacillus subtilus, suspension of Trichoderma harzainum, suspension of powder garlic cloves, mixture suspension of B. subtilus and powder garlic cloves and mixture suspension of T. harzainum and powder garlic cloves) with different concentrations were used to control root-knot nematodes, Meloidogyne incognita under laboratory, green house and field conditions on grape vine seedlings.The most effective treatment in controlling root-knot nematodes was the mixture suspension of B. subtilus and powder garlic cloves, whereas the least effective was the suspension of T. harzainum only under all laboratory, green house and field conditions. Under laboratory conditions the five treatments were used to study their effect on percentage of juvenile mortality. All treatments led to achieved the high percentage of juvenile mortality especially at the highest concentration (1:25) during all exposure periods especially after 72 hours under laboratory conditions. Using the mixture suspension of B. subtilus and powder garlic cloves was more effective in reducing numbers of galls, egg-masses and eggs per plant and number of 2 nd stage larvae in soil whereas, the least effective were the suspension of T. harzainum only under green house and field conditions. Under greenhouse conditions adding all treatments to soil led to increase the fresh weight of either the root or shoot system on grape vine seedlings at all the used concentrations especially in the highest concentration (1:25). Using three time of application per week of each treatment achieved high decrease in nematodes in both roots and soil, and increased the yield of grape under field conditions.
