Screening 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 کاملThe Colletotrichum gloeosporioides species complex
UNLABELLED The limit of the Colletotrichum gloeosporioides species complex is defined genetically, based on a strongly supported clade within the Colletotrichum ITS gene tree. All taxa accepted within this clade are morphologically more or less typical of the broadly defined C. gloeosporioides, as it has been applied in the literature for the past 50 years. We accept 22 species plus one subspec...
متن کاملPhyscomitrella patens Activates Defense Responses against the Pathogen Colletotrichum gloeosporioides
The moss Physcomitrella patens is a suitable model plant to analyze the activation of defense mechanisms after pathogen assault. In this study, we show that Colletotrichum gloeosporioides isolated from symptomatic citrus fruit infects P. patens and cause disease symptoms evidenced by browning and maceration of tissues. After C. gloeosporioides infection, P. patens reinforces the cell wall by th...
متن کاملAntifungal activity of n-hexane extracts of Datura metel against Ascochyta rabiei
The antimycotic potential of Datura metel (syn. Datura alba Nees.) was investigated in vitro against Ascochyta rabiei, the cause of chickpea blight disease. The pathogen was exposed to various n-hexane concentrations (1, 2, 3 and 4% w/v) of shoot and root extracts of D. metel using poisoning food technique. All the employed concentrations of both root and shoot extracts significantly suppressed...
