Abstract:
This experiment was conducted under laboratory and the Department of Plant Protection, (in Plant Pathology Lab ) College of Agricultural Studies , Sudan University of Science and Technology ( shambat ) to study the effect of alcoholic extract of the fruits of coriander and fungicide score250EC the fungusAternariasolani growth that causes early blight on Tomatoes.Used three concentrations of the alcoholic extract of coriander seeds (50%, 25 % and12,5 % ) and the fungicide score250EC addition to the witness has been assessed to the inhibitory effect of these concentrations logged percentage inhibition of the growth of fungus . The results showed that the concentration of all the alcoholic extract of the fruits of coriander and tested the fungicide has shown a significant effect on the laboratory compared to the control (test fungus). Concentrations of aqueous extrac may have interacted individually against the fungus with the effect is obvious to extracts of the fungicid
Concentrations least ( 12.5 % ) in each of the extracts alcoholic gave the highest percentage of inhibition compared to the control .This study concludes that coriander contains some ingredients that have the ability to inhibition , which can be regarded as a benefit for the continuation of this type of research to identify natural substances that Taatdmentha coriander.
