Evaluation of Plant Extracts against Fusarium Oxysporum F. Sp. Lycopersici, Wilt Pathogen of Tomato
Wilt is an important disease of tomato crop causing significant reduction in yield. In present study, the pathogenic fungus was isolated from infected plant and identified based on morphological and cultural characters as Fusarium oxysporum f.sp.lycopersici whose pathogenicity was confirmed by Koch’s postulate on tomato seedling. In vitro evaluation of extracts of 20 plant species was done by p...
متن کاملInhibitory Effect of Algal Extracts on Mycelial Growth of the Tomato-Wilt Pathogen, Fusarium oxysporum f. sp. lycopersici
The present study was undertaken to explore the inhibitory effect of cyanobacterial extracts of Nostoc commune FA-103 against the tomato-wilt pathogen, Fusarium oxysporum f. sp. lycopersici. In an optimal medium, cell growth, antifungal activity, and antifungal compound production could be increased 2.7-fold, 4.1-fold, and 13.4-fold, respectively. A crude algal extract had a similar effect as m...
متن کاملDeveloping of Dna-marker to the Fusarium Oxysporum F. Sp. Lycopersici Resistance Genes of Tomato
Fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici is a destructive disease of tomato crops worldwide. The use of resistant varieties is the best strategy for disease control. In the present study we analyze eight tomato lines and hybrids for Fusarium wilt disease resistance by polymerase chain reaction. Total genomic DNA was extracted from young leaves of three-week-old plants of to...
متن کاملCompost and biochar alter mycorrhization, tomato root exudation, and development of Fusarium oxysporum f. sp. lycopersici
Soil amendments like compost and biochar are known to affect soil properties, plant growth as well as soil borne plant pathogens. Complex interactions based on microbial activity and abiotic characteristics are supposed to be responsible for suppressive properties of certain substrates, however, the specific mechanisms of action are still widely unknown. In the present study, the main focus was...
متن کاملThe Tomato Wilt Fungus Fusarium oxysporum f. sp. lycopersici shares Common Ancestors with Nonpathogenic F. oxysporum isolated from Wild Tomatoes in the Peruvian Andes
Fusarium oxysporum is an ascomycetous fungus that is well-known as a soilborne plant pathogen. In addition, a large population of nonpathogenic F. oxysporum (NPF) inhabits various environmental niches, including the phytosphere. To obtain an insight into the origin of plant pathogenic F. oxysporum, we focused on the tomato (Solanum lycopersicum) and its pathogenic F. oxysporum f. sp. lycopersic...
