Effect of some bio-factors against the sclerotinia sclerotiorum fungus causing white mold disease on eggplant in vitro

Abstract EN

The study aimed to evaluate the efficacy of some plant extracts and Bio-factors against the Sclerotinia sclerotiorum fungus causing white mold disease on eggplant in vitro.

The results of isolation and diagnosis showed three isolates of Sclerotinia sclerotiorum.

The results of isolation and diagnosis showed three isolates of Sclerotinia sclerotiorum.

The results showed that the fluorescens Pseudomonas bacteria had a significant effect in inhibiting the growth of isolate of pathogenic fungi that causing white mold disease of eggplant.

The results also showed the Effective microorganism extract (EM-1) in inhibiting the growth of the tested pathogen isolate (S.

sclerotiorum (Sc-2)), where the percentages of inhibition amounted to (100.

00%).

The results showed that all used plant extracts to study their effect against the pathogenic fungus (S.

sclerotiorum), which included the leaves of the water hyacinth, Hornwort, and Conocarpus, achieved high effectiveness of inhibitory against the growth of pathogenic fungi on the culture media and in a direct relationship with an increased focus for each treatment.

The results indicated that the aqueous extract for the Propolis was inhibiting activity against the pathogenic isolate for the fungi pathogenic (Sc-2), where the percentages of inhibition amounted to (50.

77, 52.

92 and 74.

13%) when adding concentrations of (5, 10 and 15%), respectively.

This study showed, for the first time in the world, the efficiency of the cold aqueous extract for propolis and the leaves extract for the water hyacinth, Hornwort, and Conocarpus against the S.

sclerotiorum fungus that causing white mold disease on eggplant.
