against Fusariumoxysporum pathogenic to asparagus, carnation and strawberry, as well as its safety in asparagus plants. A significant inhibition of mycelial growth and sporulation of F. oxysporum f. sp. asparagi, F. oxysporum f. sp. dianthi and F. oxysporum pathogenic to strawberry was obtained by the addition of the asparagus extract enriched in flavonoids in three independent experiments and using the amended plate technique.Our results constitute the first report of the antifungal properties of bioactive compounds, mainly flavonoids, from asparagus by-products, and show these extracts as a promising alternative within horticultural crop protection strategies..

Biological control of Fusarium wilt of potato (Fusarium oxysporum f. sp. tuberosi) by Trichoderma isolates under field condition and their effect on yield Abstract Application of Trichoderma species is a harmless method in controlling soil borne plant diseases thus reducing hazardous pesticide use and environmental pollution. Some Trichoderma isolates performing proper inhibitory effect against Fusarium oxysporum f. sp. tuberosi under laboratory and green house conditions were screened against wilt disease of potato caused by this pathogen under field condition in Shahrood Agricultural Research Center, Iran, during 2009-2010. Results of two years field studies indicated that T. virens (T7) followed by T. asperellum (T2) were superior to others in reducing the disease in comparison to infested control. In comparison to Fusarium infested plots, yield was higher in all plots treated with Trichoderma, but highest yields were obtained from plots in which T. virens (T7) and T. asperellum (T2) were involved respectively. It might be stated that isolates of T. virens and T. asperellum are among the effective biocontrol agents against Fusarium wilt disease of potato and can be used as formulated biofungicides in reducing this disease.
