| Abstract | ||
| This study conducted in the laboratories of Horticulture Department / Agriculture College / University of Kirkuk, to study the effectiveness of alcoholic and aqueous extracts with three concentrations (0, 0.25, 0.5)g/011 ml for each of the seeds (Sorghum Halepens L.) and (Lantana Camera L.) leaves on the growth of some plant pathogenic fungi ( Aspergillus niger, Rhizopus stolonifer and Penicillium oxalicum). The chemical analysis of plants showed that containt tanines, flavonoids ,resins, glycosides ,saponoids and alkaloids.The results showed the inhibition effectiveness of aqueous and alchoholic extracts against the fungi used , especially the concentration of 0.5 g / 011 ml gave the best results . The study showed that the highest percentage of inhibition was on fungus Penicillium oxalicum ( 04.56 ) when aqueous extract of (Sorghum Halepens L.) seeds in the concentration of 0.5 g / 011 ml was used . And the results indicate that the fungus Penicillium oxalicum was more sensitive to the alchoholic and aqueous extract of (Sorghum Halepens L.) and ( Lantana Camera L.) leaves ( 05 , 04.5, 02.5, 04.0) %, respectively, at the concentrations of 0.5 g / 011 ml and results showed that the aqueous extract of the (Sorghum Halepens L.) seeds and (Lantana Camera L.) leaves affected more in the rate of fungal growth, the percentage of inhibition of the fungi (A. niger and R. stolonifer and P. oxalicum) were (05.0, 0..5, 04.5)% for the (Sorghum Halepens L.) seeds and ( 02.5, 04.0, 04.0)% for (Lantana Camera L.) leaves respectively at a concentration of 0.5 g / 011 ml and the effect of alcoholic extract of (Sorghum Halepens L.) was better than the (Lantana Camera L.) leaves at a concentration of 0.5 g / 011 ml with the inhibition of (0., 0., 05)% of (Sorghum Halepens L.) seeds compared with (Lantana Camera L.) leaf against fungie . A significant differences between the levels of concentration and its effects on the rate of growth of fungi were recorded, the concentration of 0.5 g / 011 ml was more significant than other concentrations which record ..15 cm for the A.niger and ..00 cm for the (R. stolonifer) and 2.50 cm for the ( P. oxalicum). While we note that the comparison treatment for these three fungi recorded the highest growth rate of 5.2. cm for the (A.niger) and 5.05 cm for the (R. stolonifer) and 5.0. cm for the (P. oxalicum) . | ||
