This study included the assessment of the antifungal activity of extracts of Cuminum cyminum, Zingiber officinale and Citrullus colocynthis on the growth of Macrophomina phaseolina. Additionally, the toxicity effect of the fungal filtrate on the percentage of okra seeds germination as well as some okra parameters. The results showed that the alcoholic extract of Cuminum cyminum had a significant effect on the inhibition of the radial growth and dry weight of M. phaseolina followed by Zingiber officinale and citrullus. Among the all extracts, Cuminum cyminum extract gave the highest germination, which was 66%, while the Zingiber officinale and Citrullus colocynthis had lowest effect on the germination by 53.3 and 46.2 respectively. The concentration of 50% tends to have a significant influence on okra seeds germination 55.1% than 25% concentration. The alcoholic extract of Cuminum cyminum had a significant effect at 3% concentration on plumule height, which was 6.2 cm, while zingiber officinale and citrullus colocynthis at the same concentration (3%) had plumule heights of 5.2 and 2.8 cm respectively. Cuminum cyminum extract also had a significant effect on the radiant, which was 1.8 cm. A similar effect on the radiant was examined to zingiber officinale which was 1.5 cm. In conclusion, the Cuminum cyminum extract exhibited a promising effect on some parameters of okra seedlings, especially for high concentrations. All alcoholic extracts under investigation showed an effective effect on infected fungi, in particular, Cuminum cyminum extract.
