All treatments showed remarkable increase in plant growth parametersas well as reduced nematode criteria. Cabbage dried leaf powder showed highereffectiveness of the tested botanical dried leaf powders and enhanced plant growthparameters with significant increase values. On the other hand, spinach dried leafpowder as soil amendments overwhelmed other treatments in suppressingnematode population in soil (78.3%), root galling number (87.0%), egg-masses(91.5%) and eggs / one gram root (91.5%) respectively. However, the least valuesof the same nematode criteria was achieved by sorrel treatment with values of34.0,77.3,90.5 and 89.3 respectively, comparing to nematode alone.

The obtained results showed that, the application of A.conoides + Wormwood + Tervigo treatment gave the highest reduction percentageof the nematode with reduction ratio of (85.0%) followed by the treatment of A.conoides + Tervigo (77.3%) in Cucumber plants and the same previous treatmentsgave (80.0% and 70.5%) in Courgette plants, respectively. Moreover, the twoprevious applications gave better enhancement in various growth parameters suchas, plant height, shoot weight, and root weight in both Cucumber and Courgetteplants. The same application gave the lowest gall index (1.0) representing thehighest total decrease in gall numbers (-83.3%) in cucumber and (-81.8%) inCourgette compared with control. There are significant differences in root gall indexbetween control treatment and all other treatments.
