Abstract

The efficacy of date palm (Phoenix dactylifera L.) agro-wastes viz. palm
fibers, green drop fruits, palm fronds and rules of leaves applied as powder or
soakage to soil at various rates of application were evaluated for their nematisidal
activates against root-knot nematode, Meloidogynejavanicaand reniform nematode,
Rotylenchulusreniformis infected common bean (Phaseolus vulgaris L.) cv. Polista
under greenhouse conditions. All the tested soil amendments of date palm wastes
significantly reduced the number of nematode in soil, developmental stages and
egg-masses per root for both nematode species as well as the number of root galls
formed by root-knot nematode on common bean roots when compared with
untreated check. Also, the percentage values of reductions of nematode final
population and egg production as well as the rate of nematode reproduction
gradually decreased with increasing the amount of agro-wastes of date palm to the
soil. The agro-wastes of green drop fruits and rules of leaves applied as powder or
soakage at the rates of 15 and 20 g/kg soil proved to be the best effect in controlling
for both nematode species than those of the other tested treatments. It is worthy to
not that the effect of the powder of agro-wastes of date palm on M. javanica
reproduction was more than the soaking agro-wastes while the soaking agro-wastes
on nematode reproduction of R. reniformis was more effective than powder agrowastes.
