Abstract:
This study was carried out in the laboratory of plant pathology, plant protection
Department, College of Agricultural Studies, Sudan University of Science and
Technology in (2017) the objective of this study was to evaluate The efficacy of
ginger (Zingiber officinale) ethanol extracts and (Fulldazim 50 WP) fungicides
against Fusarium oxysporum f.sp Lycopersion in tomato in culture media Potato
dextrose agar (PDA) in vitro. The fungi are an important causing significant
reduction in yield. In the present study, the pathogenic fungi were isolated from
infected plant parts .The fungi were identified based on morphological and
culture characters as Fusarium oxysporum f.sp Lycopersion. Studies were
conducted three concentrations of ginger ethanol extracts (25, 50 100%) in
addition to the control treated with distilled water. The results obtained that all
concentrations exhibited and has an inhibitory effects on the growth of the
fungus tested compared to control (5).The highest inhibition effect was obtained
at (100%) compered by control (5). Generally the inhibition zone increases with
increase the concentration of the extracts. In conclusion, these studies showed
that ginger contain antifungal properties that could investigate in further studies
