Abstract

A greenhouse study was conducted (0 Investigate the e'ieci of certain gel so.l
conditioners on the pathogenicity of the reniform nematode, Rotvteocnc'us renitorrrus
Infecting okra plant roots ( Abe/moschus esculentus l) For this arrn two gel 5011
conditioners were used i e .. Evergreen 500 (EG) and Broad leaf P4 (al) at 'our
concentrations, 0 (control treatment), 02, 04 and 0.6 % Kesults indicated tha: tne
Increment of EG concentrations highly significant Increased the final nematode
population with polynomial relationship On the contrary, a Significant polynomial
negative correlation ocourred between Bl concentratrons anc final nematode
poputanor.. The concentration 0.2 % of BL caused encouragement for R remtormis
final population that reached to 4679 individuals with reproduction tactor of 2.34
Generally the tested soil conditioners increased the plant growth in spite of nematode
infection.
