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 کاملIdentification and Characterization of Benomyl-Resistant and -Sensitive Populations of Colletotrichum gloeosporioides from Statice (Limonium spp.).
ABSTRACT Sixty-four isolates of Colletotrichum gloeosporioides were isolated from infected Limonium spp. cultivated in 12 different locations in Israel. All isolates were identified as belonging to the C. gloeosporioides complex by species-specific primers. Of these isolates, 46 were resistant to benomyl at 10 mug/ml and 18 were sensitive to this concentration of fungicide. Based on arbitrarily...
متن کاملMolecular and phenotypic analyses reveal association of diverse Colletotrichum acutatum groups and a low level of C. gloeosporioides with olive anthracnose.
Anthracnose (Colletotrichum spp.) is an important disease causing major yield losses and poor oil quality in olives. The objectives were to determine the diversity and distribution pattern of Colletotrichum spp. populations prevalent in olives and their relatedness to anthracnose pathogens in other hosts, assess their pathogenic variability and host preference, and develop diagnostic tools. A t...
متن کاملpelB gene in isolates of Colletotrichum gloeosporioides from several hosts.
Colletotrichum gloeosporioides is an important pathogen for a great number of economically important crops. During the necrotrophic phase of infection by Colletotrichum spp, the degradative enzymes of plant cell walls, such as pectate lyase, clearly increase. A gene pelB that expresses a pectate lyase was identified in isolates of C. gloeosporioides in avocado pathogens. Various molecular studi...
متن کاملComparison of Colletotrichum gloeosporioides Isolates from Various Avocado Producing Areas
Eighty six isolates of C. gloeosporioides isolated from avocados from various production areas were compared using fruit inoculation studies. Differences were observed, and isolates could be grouped into three groups based on lesion size. These results are preliminary and further investigation must be carried out to confirm these findings.
