Abstract EN

The efficacy of Trichoderma harzianum Rifani, Paecilomyces lilacinus (Thom) Samson, some animal organic wastes (cow, horse and sheep dungs) and the nematicide fenamiphos in the control of root-knot and root-rot/wilt disease complex of eggplant cvs.

“Rima” and “Local” was tested in two separate tests.

Experiments were undertaken in Al-Mussaib, Technical Institute during 1998/1999 seasons, in a greenhouse for cv.

“Rima” and an open field for cv.

“Local”.

Soils in both locations were heavily infested with root-knot nematode Meloidogyne spp.

and the soil-borne pathogenic fungi Rhizoctonia sp.

and Fusarium sp..

A randomized complete block design with four replicates was used in each experiment.

Results of both tests were similar, and showed that all treatments except cow dung greatly increased (P≤0.05) the eggplant yield compared to the non–treated control, and suppressed (P≤0.05) the percentage of nematode-infected plants.

However, all treatments except cow and sheep dungs reduced (P≤0.05) the disease index (root galling) on a 0-5 scale.

Maximum reduction of root galling and increase of eggplant yield was obtained where Fenamiphos was used, followed by T.

harzianum , P.

lilacinus and horse dung.
