A greenhouse trail was conducted to study the influence of five plant dried
leaf powders i.e. cabbage, sorrel, spinach, rocket and tomato in comparing with
oxamyl on root-knot nematode M. incognita infecting eggplant under greenhouse
conditions. All treatments showed remarkable increase in plant growth parameters
as well as reduced nematode criteria. Cabbage dried leaf powder showed higher
effectiveness of the tested botanical dried leaf powders and enhanced plant growth
parameters with significant increase values. On the other hand, spinach dried leaf
powder as soil amendments overwhelmed other treatments in suppressing
nematode 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 values
of the same nematode criteria was achieved by sorrel treatment with values of
34.0,77.3,90.5 and 89.3 respectively, comparing to nematode alone. The recorded
results showed a potential properties of using such plant dried leaf powders as ecofriendly
control method instead of chemical pesticides.
