Chemical Composition and Antifungal Activity of Trachyspermum copticum Essential Oil Against Alternaria alternata (In-Vitro Study)
Background: Alternaria alternata (AA) is a fungus that has wide range of plant host and can cause diseases in humans and produces a number of mycotoxins. Exposure to high numbers of AA spores can trigger severe asthma exacerbations. Resistance to antifungal drug has been shown in this species. Trachyspermum copticum (Ajowan) is an annual herbaceous essential oil )EO) bearing plant . The ripenin...
متن کاملAntifungal activity of diketopiperazines extracted from Alternaria alternata against Plasmopara viticola: an ultrastructural study.
Three dipeptides, belonging to the family of diketopiperazines (DKPs), were extracted from broth culture of the grapevine endophyte Alternaria alternata, and were tested against Plasmopara viticola on leaves of grapevine plants grown in greenhouse. DKPs, used at different concentrations (10(-3), 10(-4), 10(-5) and 10(-6)M) both singularly and in mixtures, demonstrated real effectiveness in inhi...
متن کاملScreening of Antagonistic Activity of Microorganisms against Colletotrichum Acutatum and Colletotrichum Gloeosporioides
The antagonistic activities of five biocontrol agents: Trichoderma harzianum, Gliocladium roseum, Bacillus subtilis, Streptomyces noursei and Streptomyces natalensis, were tested in vitro against Colletotrichum acutatum and Colletotrichum gloeosporioides, the causal agents of anthracnose disease in fruit crops. The microbial antagonists inhibited mycelial growth in the dual culture assay and co...

متن کاملGlobal antifungal profile optimization of chlorophenyl derivatives against Botrytis cinerea and Colletotrichum gloeosporioides.
Twenty-two aromatic derivatives bearing a chlorine atom and a different chain in the para or meta position were prepared and evaluated for their in vitro antifungal activity against the phytopathogenic fungi Botrytis cinerea and Colletotrichum gloeosporioides. The results showed that maximum inhibition of the growth of these fungi was exhibited for enantiomers S and R of 1-(4'-chlorophenyl)-2-p...
