Antagonistic effect of activity of Propolis, Royal Jelly and Bio-control agent, Trichoderma harzianum Rifai in growth of fungal pathogen Rhizoctania solani Kuhn.

Abstract

The research aimed to study the effect of different concentration of proplis and Royal jelly extracts (0, 20, 40 and 60)% and colony filtration at bio - control agent, T.harzianum in growth of fungal pathogen R.solani and compared these results. Results Showed that the 60% concentration of T.harzianum was the most active in effect of R.solani growth inhibition reached 100%. Generally the T.harzianum appeared high efficacy in fungal in pathogen R.solain inhibition with diameters average ( 5.1, 3.2 and 0.0)Cm. at (20, 40 and 60) %concentration respectively. While proplis extracts was lower inhibition efficacy. Whereas Royal jelly extracts had low effect in R.solani growth inhibition, them selver with diameters averages reached (6.0, 4.0 and 3.5)Cm. at (20,40and60)% concentration respevtivey .
